Look at the face value, spell the inside story, compare the quality … What do you eat with cold drinks?

  For many people, summer begins with a bottle of iced soda and an ice cream. Bingfeng, Nongfu Spring, Yili, Mattel, Zhong Xuegao … … Today’s cold drink market is very lively, with endless new brands and innovative old brands; There are both local ice products and national famous products.

  With the general trend of consumption upgrading, the cold drink industry has ushered in a new revolution. In this wave, who can be the guardian of consumers’ cool summer? What do people eat when they eat cold drinks nowadays?

  "online celebrity" appears frequently

  New and old brands lay out high-end markets.

  On a hot summer day, Feng Chenxi, a post-90s worker working in Chaoyang District, Beijing, walked into a convenience bee shop next to the company, looking for a cold drink to cool off. However, when he entered the store, he was a little confused, with ice cream, iced drinks and yogurt. After a cursory glance, I was attracted by a "small fresh" package in the freezer. This is a "boiled leaf" ice cream, which was jointly produced by Zhong Xuegao and Wufangzhai. "I didn’t eat zongzi during the Dragon Boat Festival, so just try this!" Without looking at the price, I directly deducted the payment code, and only after this deduction did I know that one wanted 15 yuan, which was a little expensive.

  "Fortunately, it tastes good, the fragrant leaves are mixed with milk, and there is a sticky feeling of glutinous rice." Feng Chenxi said.

  In Feng Chenxi’s impression, domestic cold drinks are mostly cheap, and only a few foreign brands can sell at this price. Recalling the midsummer when I was a child, a bag of "ice packs" with a dime could make him smile. The packaging of an ice pack is extremely simple, just an icicle wrapped in plastic. When he and his friends were sweating, they went to the grocery store to buy an ice pack. First, they put it on their faces and foreheads, which made them instantly cool. Then, when they were full of handfuls, they began to suck eagerly, and the coolness went straight to their foreheads … …

  This simple cold drink blended with pigment and sweetener has accompanied many people’s childhood. "That’s the coolest taste in summer." Feng Chenxi said.

  In recent years, driven by some cutting-edge brands, domestic ice products have continuously raised their price ceiling. There are more and more domestic ice creams above 10 yuan, but those below 10 yuan are rare. The unit price of Zhongjie 1946 and Zhong Xue’s high-quality ice cream is above that of 10 yuan, and the price of an "Ecuadorian pink diamond Ice Cream" that makes Zhong Xue’s high fire "out of the circle" is as high as that of 66 yuan.

  Seeing the cutting-edge forces overtaking in corners, the old players are also actively laying out the mid-to high-end market, and the cold drink market has entered the "10 yuan era".

  Yili has held the top spot in the domestic cold drink market for many years, and its ice factory, Qiaolezi and other products are deeply loved by consumers, but it needs new faces to open up the situation in the middle and high-end market. "With the rise of ice cream rookie brands, more innovative brands have entered the market with mid-to high-end products, which has led to fierce market competition. The brand side provides healthier and more unique products through continuous product and marketing innovation. " The relevant person in charge of Yili Group said. On the basis of affordable models, Yili launched new products such as rare and rare products, which successfully helped the brand to stabilize its market position.

  "Ice cream is the most eye-catching consumer product in midsummer. The sales of ice cream in convenience bees, Yili, Menglong and other places around 10 yuan are very high. In addition, online celebrity products with high prices are mostly the favorite of white-collar workers in business districts, such as Zhong Xuegao and Xicha ice cream." The person in charge of the convenience bee said.

  Not just to relieve summer heat.

  Full of creativity, attracting people to punch in

  Nowadays, domestic cold drink brands have gradually gained a foothold in the mid-to-high-end market and have the ability to wrestle with international brands, whether in couples shops on the street, convenience chains or large supermarkets. Behind the ever-increasing price is the all-round change of products by manufacturers. Raw materials, modeling, technology and packaging … … All aspects of cold drink production and research and development are constantly changing, which stems from manufacturers’ accurate grasp of the changes in consumption concepts.

  Ice cream brands frequently arouse consumers’ curiosity with richer flavors: durian flavor, toffee flavor, AD calcium milk flavor and salted egg yolk flavor … … "The new generation of consumers who seek novelty and novelty are more willing to pay for early adopters. They are less sensitive to price and pay more attention to factors such as product quality, taste, packaging and freshness. The rise of differentiated demand has promoted the growth of consumption of quality products. " Insiders analyzed.

  The popularity of Wenchuang ice cream this year is an example.

  Before going to Wuhan for the Dragon Boat Festival holiday, Wang Qi saw someone sharing "Yes ‘ Eat ’ The Yellow Crane Tower was planted with grass in an instant. "The ice cream has fine texture, realistic shape and good taste. It’s one from 15 yuan, and the price is not too expensive. It’s cool to take pictures in front of the Yellow Crane Tower!"

  Well-known scenic spots such as the Forbidden City, West Lake, Leshan Giant Buddha, etc., are all combining their own characteristics to launch a unique style of cultural and creative ice cream, and taking pictures in front of the "deity" with ice cream in the shape of landmark buildings or cultural relics has become a new fashion for tourists to punch in.

  Taking advantage of the popularity of cultural relics, Sanxingdui introduced two bronze masks "doll head" ice cream, which was robbed that morning. According to Feng Shixiong, an ice cream designer, there will also be a variety of products with different shapes and flavors, such as bronze giants and bronze birds, so that visitors to Sanxingdui can see, eat and bask in their circle of friends.

  Nine-story pagoda in Mogao Grottoes, Horse Head in Yuanmingyuan, Yungang Grottoes … … Wenchuang ice cream in various scenic spots attracts tourists’ attention, and some prices reach tens of yuan, and many consumers are still willing to queue up.

  The new "online celebrity" attracts attention by creating a sense of topic, while the old brand wins by virtue of tradition.

  Founded in 1906, Mattel can sell more than 10,000 ice creams every day, regardless of the cold and heat. In the crowded central street of Harbin, it is almost a standard action to buy a Mattel popsicle to take pictures — — Not to quench your thirst, just to make a card.

  "The function of cold drinks is changing, and it gradually carries more cultural and social attributes. At present, the products of the head ice cream brand in the market may have little difference if they only compare their tastes. For young people, choosing a fast-moving consumer product is largely to express their personality. " Sun Zubin, general manager of Maddie Group, said, "Maddie is the earliest popsicle brand in China, and has always adhered to the old technology and several traditional tastes. This inheritance is the core competitiveness of the brand. What was the taste of popsicles that people ate more than 100 years ago? For consumers, it is a rare cultural experience. "

  Return to quality

  Cold drinks grow red only when they are delicious

  Novelty tastes are refurbished, and the styles are exquisitely crafted. In the cold drink market where product upgrading is accelerating, there are always new products and ways of playing. However, no matter how it changes, cold drinks are food after all, and what goes into the stomach is its root. The key to changing from "online celebrity" to long red lies in whether the products can go from mouth to heart.

  "Yili cold drink has a history of 29 years. Walking in the streets, wherever there is a freezer, there will be Yili ice cream. " The relevant person in charge of Yili Cold Drink Division said that the word-of-mouth accumulated over the years is the greatest wealth of the brand. Taste, product line and channel are changing, but the insistence on quality makes the brand ride the wind and waves in the fierce market competition.

  "Health has gradually become an important dimension to measure the quality of cold drinks." The relevant person in charge of Yili Cold Drink Division said that Yili’s "Have some oatmeal" ice cream uses milk with natural oatmeal particles, and milk protein and plant protein collide to create delicious and healthy. Another ice cream brand "Must Be Happy" focuses on providing consumers with high-quality ice cream with advanced liquid nitrogen extraction technology and patented live bacteria without artificial colors, flavors and preservatives.

  "Consumers are increasingly demanding the quality of beverages, which requires enterprises to work hard on products, constantly improve quality, and truly make ‘ Online celebrity ’ The product becomes long red. " The relevant person in charge of Nongfu Spring said.

  Recently, it was discovered that the oriental leaf "Jasmine Tea" tastes different. "The floral fragrance is more full, natural and refreshing, and it is more suitable for drinking in summer."

  "Consumers’ demand for sugar-free tea is not just sugar-free, but a comprehensive experience based on taste, which is an invisible competition for brands ‘ Barriers ’ 。”

  Quality is the lifeline of the brand. This is true for Nongfu Spring in the twenties, and it is also true for Xi ‘an Bingfeng in the seventies. In the 1990s, Coca-Cola entered the Xi ‘an market in a big way, and tried its best to defeat the ice peak. The glass bottle was filled with 50ml more, and the wholesale price was 5 cents cheaper. Even so, it failed to make the ice peak fall.

  "This is certainly not just feelings. Guangxi’s high-quality white sugar, multi-channel purified water, glass bottles that have undergone four procedures of soaking, cleaning, disinfection and drying for 40 minutes, and the consistent craftsman spirit ensure the quality of Bingfeng soda, which makes us win the recognition of Xi’ an citizens and tourists from all over the world. " The head of the brand department of Xi’ an Bingfeng Beverage Co., Ltd. said.

  Nowadays, as the tourism market in Xi ‘an continues to be hot, Bingfeng goes out of Xi ‘an with the help of the Internet and pushes products to the whole country through new retail. In addition to sticking to the taste, Bingfeng also followed the footsteps of the times to create diversified products. New packaging and new tastes enriched the product matrix and accelerated the pace of Bingfeng’s stepping out of the land of Sanqin.

  Cold drink consumption will usher in more and faster changes. In the past, an ice cream and a bottle of soda accompanied several generations to grow up, but now the same generation is witnessing the changes and upgrading of different cold drink brands. What can stay is a brand that is more adaptable and innovative on the basis of excellent quality. (Kang Pu Han Xin)

Do you know this knowledge about "old man’s music"?

Do you know the knowledge of "Old Man’s Music"?

Overview of "Old Man’s Music": Definition and Characteristics "Old Man’s Music" mainly refers to low-speed electric three-wheeled and four-wheeled vehicles. It is named because of its simple operation, affordable price and meeting the driving needs of the elderly. This kind of vehicle usually has the following characteristics. Do you know the knowledge of "Old Man Le"?

Cheap price: Compared with traditional cars, the price of Lao Toule is lower, which is more easily accepted by consumers with limited budgets, especially the elderly.

Simple procedures: Early old people may not need complicated licensing procedures or driver’s license requirements in some areas, and the threshold for purchase and use is relatively low.

Application scenario: it is mainly used for short-distance transportation, especially in rural areas, small towns or closed communities, as a connecting tool or daily travel. Development course and supervision policy

Early development: Laotoule has various origins, which may be related to golf carts, three-wheeled agricultural vehicles and other similar means of transportation. Since the early 2000s, it has been rapidly popularized in rural areas of China. Do you know the knowledge of "Old Man’s Music"?

Standardization and upgrading: With the growth of market demand and the prominent problems of safety and environmental protection, the government began to gradually strengthen the supervision of Laodule. For example, the regulations before 2021 require that such vehicles be formally included in the standards of new energy vehicles within six months, and lead-acid batteries should be replaced by Ferrous lithium phosphate or ternary lithium batteries. At the same time, manufacturers are required to meet the standards of crash test, vehicle quality and motor performance.

Market changes: After the domestic retirement of the non-compliant Laole, the micro-new energy vehicle market has received more attention. In the international market, the old man music products made in China have even attracted the interest of European and American consumers. Brand and market situation Brand participation: There are many enterprises focusing on the production of Laodule in the market, such as Reading Automobile, which compete in this segment.

Product evaluation: Although the market exists, there is a view that as of a certain point in time (for example, in 2022), Laotoule manufacturers have not yet launched models that can compete with the mainstream products in the domestic new energy vehicle market at that time.

Influence and controversy

Social demand: Laotoule really meets the travel needs of some specific groups (especially the elderly) and provides convenient transportation solutions.

Safety and environmental protection issues: Due to the lack of unified standards and strict supervision in the early stage, Laotoule may have potential safety hazards, such as insufficient structural strength and poor braking performance. In addition, the old man who uses lead-acid batteries has a certain impact on the environment, which is why the policy later requires him to switch to a more environmentally friendly battery type.

To sum up, "Laotoule", as a special type of low-speed electric vehicle, played an important role in transportation in a specific period and region, but its development was accompanied by increasingly strict legal requirements, market transformation and the demand for safety and environmental protection performance improvement. With the advancement of standardization, the old man music industry is gradually moving closer to the standard of micro new energy vehicles to adapt to the new market environment and regulatory requirements.

Ruan Jingtian’s Love Entanglements and Gossip Past

The love life of Ethan Ruan, the former stud star, has always been in the spotlight. His love affair with Liu Pinyan and his eight-year relationship with Xu Weiyuan have attracted widespread attention. However, there are many controversies and untold stories in these relationships.

In recent years, there have been fewer and fewer opportunities for Ethan Ruan’s work to be screened in China. After the broadcast of his work "Heartbeat on the Bite of the Tongue", the reputation has been declining all the time, and the reviews on Douban are all bad. Audience reviews of the show can be summed up as: the cliché Mary Su drama. In this drama, Ethan Ruan also has a fierce love affair with the actress.

During the filming of "A Bite of My Tongue," people familiar with the matter broke the news that Ethan was in love with Song Zuer, who was 16 years younger than him. However, as soon as the news broke, Ethan Ruan and Song Zuer’s team immediately denied it. However, this did not stop the media from continuing to dig into their romance. Soon after, Ethan Ruan was photographed going to Hengdian alone to visit Song Zuer, and the relationship between the two seemed to be closer.

However, this relationship did not last long. In July 2022, Ruan Jingtian’s new girlfriend was exposed, and it was suspected that Song Zuer’s best friend broke up with Ruan Jingtian to the Taiwanese media. The specific reason is unknown.

Mr. Nguyen’s love life has been contentious. He broke up with his girlfriend, Yvonne, forcibly for his career and demanded that she abort her pregnant child. Although Mr. Nguyen has denied this, the woman has provided no substantive evidence. In addition, he also fell in love with a female agent, Xiao Ren, but eventually broke up and injured Xiao Ren. In his relationship with Liu Pinyan, Liu Pinyan was only 17 years old and was still a minor.

Overall, Ethan’s love life is full of twists and turns and challenges. His love story has attracted a lot of attention, but also caused a lot of controversy. In the days to come, we expect him to bring more excellent works, and we also hope that he can have a good ending in terms of relationship.

  However, the reporter tried to use the ride-hailing service on the morning of the 19th, but no driver had taken the order as of press time.

  ID card can only be photographed and uploaded.

  In the identity verification, the reporter noticed that Didi Hitch requires both passengers and car owners to upload ID photos. The upload can only use the "photo" function, not the "select from the gallery" function, which means that the uploaded ID card can only be taken on site, not pictures and previous photos. After uploading the ID card, face verification is also required, and the task can only be completed after both are completed.

  Car owners need facial recognition to receive orders

  Hitch owners must perform facial recognition before each order, and compare the current order owner with the platform authentication identity when registering through facial security recognition technology.Owners who fail facial recognition cannot take orders

Xiaomi’s new first-class air conditioner (1 horse) evaluation: high quality, low price, high value, intelligent control, huge power saving

[Technology Dog]

Xiaomi’s new first-class air conditionerIt has become the hottest star item in the Xiaomi brand at present. Many netizens and users have developed interest and expectations for this new product. The new first-level energy-efficient "giant power-saving" air conditioner includes 1, 1.5, 2 and 3 models, priced at 2099 yuan, 2299 yuan, 4299 yuan and 5299 yuan respectively.

So…Huge power saving | Xiaomi’s new first-class air conditionerIs it worth buying? Objectively understand it through the in-depth experience of the technology dog.

Before the evaluation, the technology dog first talks about the installation of air conditioners. This Xiaomi mall has been publicized in detail, including the installation tariffs in special environments, etc. The actual installation process is also very simple. If you place an order to buy an air conditioner, the customer service staff will call you when it arrives, and the two parties can agree on the installation time. It should be noted that the installation time of air conditioners is about two hours, including punching holes, indoor unit installation, outdoor unit punching, installation and the most important air conditioner debugging work. In the evaluation later, the technology dog said that it will be emphasized.

Note: The air conditioner tested in this article is Xiaomi’s new first-class air conditioner. The views and test results described only represent the measured products in this article and are for the reference of netizens only.

Appearance analysis: Continuation of G-Mark Gold Award design, fit-fit design saves space

But let me get back to that.Xiaomi’s new first-class air conditionerThe appearance design. It still continues the product style of Xiaomi. Dozens of products have been baptized. The industrial design style of Xiaomi products has been deeply rooted in the hearts of the people. The gray and white color matching, simple industrial design, as long as you are not using the traditional Chinese or American retro home style,Xiaomi’s new first-class air conditionerIt should be able to harmoniously form a unified, fit-in design to save space.

The biggest difference in the appearance of the whole machine is the use of UV-resistant HIPS panels, the biggest feature is that it is not easy to change color. A round LED screen on the right side of the front of the fuselage, although like a traditional air conditioner, it still bears the task of displaying details such as temperature and wind speed, but the higher resolution allows this screen to display more text information, and the style of the screen is more appealing to technology enthusiasts. And another "big screen" appeared on the remote control,Xiaomi New Level 1 Air ConditioningThe remote control borrows the layout of the Internet TV remote control, reducing buttons and putting more settings on the screen.

Xiaomi’s new first-class air conditionerAlso called"Huge power saving | Xiaomi’s new first-class air conditioner"DC frequency conversion constitutes the most important technical index of this air conditioner." Frequency conversion "refers to the adjustment of the motor’s running speed by expanding the power supply frequency range of the air conditioner motor.

For example, the motor of a traditional fixed-frequency air conditioner is equivalent to a car that cannot adjust the throttle. When the room temperature is higher than the predetermined temperature, the "throttle" is stepped to the bottom and works at high load. When the room temperature reaches the predetermined temperature, the throttle is released and does not work at all. Therefore, it is difficult to maintain a constant temperature, giving people the feeling of hot and cold.

The inverter air conditioner is like a car with a delicate throttle. When the temperature difference is large, it will step on the throttle vigorously. When the temperature difference is close, it will step on the throttle slightly and cool with low power, so that the room temperature is relatively constant and the body feels good. And "DC" refers to the use of a brushless DC motor in the air conditioner. This motor is relatively small in size and high in efficiency, which can effectively reduce the power consumption of the air conditioner. It supports accurate temperature control at 0.5 ° C, optional seven-speed wind speed, and also supports one-button energy-saving mode, which can intelligently reduce power consumption.

Intelligent moisturizing is also a big selling point. Xiaomi has innovatively developed the dual temperature and humidity control function, which adopts 0.5 fine temperature regulation and is matched with a 45% to 65% humidity control range to make humidity and temperature changes more comfortable. It should be noted that the moisture control function is only suitable for warm and moist environments to reduce and maintain comfortable air humidity. At present, it is temporarily impossible to provide humidification services for users in dry environments.

Xiaomi’s new first-class air conditionerThe design of the feeding trend is special, using an integrated arc heat exchanger, with a large heat exchange area, high cooling and heating efficiency; large-diameter cross-flow fan with 80mm length of arc-shaped wind guide plate, so that the air is stronger and the air is farther.

Xiaomi’s new first-class air conditionerThe air conditioner is also equipped with electric auxiliary heating function, which makes the air conditioner have both large cooling capacity and high heating capacity, allowing you to feel the desired temperature in a space of 16-23 square meters. The fan blade adopts a blade design to ensure large air volume while reducing noise.

Technology dogs discovered through visual inspection,Xiaomi’s new first-class air conditionerIn the design of the air duct, a special method is also adopted, using the type line design of the air duct, which minimizes the turbulence of the air flow, and at the same time enhances the air circulation and makes the air supply smoother. At the same time, the noise is also effectively controlled to minimize the noise caused by wind noise.

openXiaomi’s new first-class air conditionerThe panel has an unobstructed view of the internal structure. The one-time injection molding bacteriostatic filter screen is adopted, and the filter screen has good flatness and high connection strength. This design is conducive to enhancing the filtration effect and ventilation efficiency. At the same time, the filter screen can be washed with water and kept clean at all times. At the same time, the antibacterial rate exceeds 99%. After the air conditioner is turned off after refrigeration or dehumidification, it will continue to keep the fan running for a period of time to blow dry the condensate in the evaporator, which has an anti-mildew effect. Xiaomi’s new first-class energy-efficient air conditioner also supports self-cleaning mode. With hydrophilic aluminum foil fins, the dirt is automatically cleaned. At the same time, an antibacterial and anti-mildew filter screen

Xiaomi’s new first-class air conditionerThe design of the remote control is rather special, obviously larger than that of other smart hardware remote controls in the Xiaomi ecological chain, and the overall shape design is still Xiaomi minimalist. The operation logic is almost indistinguishable from ordinary air conditioners, and simplicity and ease of use are still the genes of Xiaomi products.

If it cannot be controlled by the remote control and mobile APP.Xiaomi’s new first-class air conditionerWhen, you can use the emergency operation button to operate. The control button needs to open the front panel of the air conditioner indoor unit and is located on the right below the front panel, as shown in the red circle below.

In the shutdown state, press the emergency switch to turn on the air conditioner and start the automatic mode to run automatically. The air conditioner will automatically select the cooling/heating mode according to the current room temperature, and then press the emergency switch to enter the shutdown state.

Xiaomi’s new first-class air conditionerContinuation of G-Mark Gold Award design, "Appearance is justice". The overall appearance is simple, fashionable, and very in line with the aesthetic standards of modern people. It is suitable for various types of decoration styles. Technology Dog believes thatXiaomi’s new first-class air conditionerIn terms of appearance, it is still very beautiful and durable. The white color scheme is particularly elegant, and it can give people a cool feeling at first glance.

First use and measured effect

Through the above introduction, the netizens have alreadyXiaomi’s new first-class air conditionerWith a certain understanding of the appearance and some technical characteristics, the first use also requires WiFi networking, which is included in the installation service. The installer needs to power on the indoor and outdoor units of the air conditioner before installing on the wall, and the user needs to perform WiFi networking adaptation. Even if the user has no experience in networking adaptation, there is no need to worry, because the installer will help you complete this operation during this process.

First of all, users can download the Mijia APP according to the QR code on the manual. If you have used Xiaomi products, there will definitely be the Mijia APP application. After the download and installation are completed, open the "Mijia APP", and the APP can be searched at this time.Xiaomi’s new first-class air conditioner, At this time, the Wi-Fi indicator light above the air conditioner is flashing and waiting to connect. When the Wi-Fi indicator light is on, it indicates that the connection is successful.

After the connection is successful, it can be displayed normally in the Mijia APP. "Xiaomi’s new first-class air conditioner"Now, click to enterXiaomi’s new first-class air conditionerThe operation interface of the mobile APP is basically similar to the operation logic of the remote control, and there is basically no difficulty in getting started. You can master it in a few seconds.

So let’s start.Xiaomi’s new first-class air conditionerThe working noise (automatic heating mode) is detected 1.5 meters below the trend of the air conditioner by installing the decibel detection APP on the mobile phone, and the average value within one minute is calculated. When the air conditioner is turned off, the average indoor noise is 35dB. Turn on the air conditioner and set it to automatic mode. At this time, the wind is the smallest, the average value is 41dB per minute, and the maximum wind is 50dB. So in the night sleep state, the noise of the space does not cause any trouble to falling asleep.

Since it is currently winter,Xiaomi’s new first-class air conditionerThe cooling function of the dog cannot be tested. When the weather turns hot in the future, the technology dog will supplement the test results in this regard.

It should be noted that the trend temperature of the air conditioner is determined by the ambient temperature. There are national standards for the trend temperature of the air conditioner. The temperature difference between the trend temperature and the trend temperature is greater than 8 degrees in the cooling state; the temperature difference in the heating state is not less than 18 degrees for the normal trend temperature. There is no specific value, only related to the ambient temperature. The higher the ambient temperature, the higher the trend temperature (heating) The lower the room temperature during cooling, the lower the trend temperature.

Voice control and mobile APP experience

Users can achieve AI in-depth control of the product through voice. Xiaomi speakers/touch screen versions/TVs and other products are bound to the Mijia APP. After authorization, they can be controlled through the voice interaction of the speaker, and the air conditioner can be controlled by voice, giving people a very different feeling.

For example: "Xiao Ai, turn on the air conditioner", Xiaomi AI speaker voice broadcast: "Okay, turn on the air conditioner". The tedious opening steps are solved in one sentence! Thanks to the strong ecological chain behind Xiaomi, Xiao Ai acts as the smart home center, allowing you to stay away from various remote controls, and operating these smart appliances only takes "one sentence".

In fact, if you have a Xiaomi TV with PatchWall artificial intelligence system at home, you can also control the air conditioner by voice.

What if you don’t have Xiaomi speakers?

Xiaomi’s new first-class air conditionerIt also supports Xiao Ai’s intelligent voice control, and controlling the air conditioner is "a matter of one sentence". Turning on and off the machine, adjusting the temperature, changing the mode, adjusting the air volume, timing switch, etc. can be done in one sentence. There is no need to wake up the remote control at night, and there is no need to wake up the mobile phone in the dark. Control the air conditioner can be realized in one sentence.Xiaomi’s new first-class air conditionerRedefine peace of mind, peace of mind, and comfort.

With various sensors of Xiaomi Smart Home, various start and stop conditions of the air conditioner can be refined, such as turning on the air conditioner when the room temperature is higher than 30 degrees, and turning off the air conditioner when the room temperature is lower than 26 degrees. The specific operation is as follows:

The existence of Xiaomi Mijia’s ecological chain allows you to comprehensively consider a group of products and set up more complex scene linkage control methods. When the window is opened, the air purifier and air conditioner are automatically turned off, and when the window is closed, these devices are automatically turned on again. Or turn on the TV, turn on the ceiling light, in short, you can make any combination according to the actual situation. The new products that Xiaomi continues to add also provide room for upgrades in the follow-up gameplay of air conditioner operations. Looking forward to more gameplay.

How is the installation?

Unlike unpacking and ready-to-use electronic products, air conditioners have always been said to be "three points by buying, seven points by installing", and the quality of the installation directly determines the stability and reliability of the use of air conditioners. The first look at the door is an experienced old master, who is serious and cautious in the communication. The tools will be laid with a flannel first, and then arranged in a straight line.

During the key stages of installation, the master will use instruments to measure and ask the user to check together, such as whether the whole machine is installed level, whether the circuit is well grounded, etc. All steps will be recorded on a list. And on installation issues, he also communicates with the technology dog, such as how to use the air conditioner correctly, how to clean the air conditioner, etc.

The vacuum process in the installation of inverter air conditioners is the hardest hit area for many installation teams to cut corners. They often take advantage of unprepared people to escape for ten minutes, and this time Xiaomi took half an hour to install. Through communication with the installer, Xiaomi stipulates that the vacuum process cannot be less than 20 minutes, the standard time is half an hour, and the pressure gauge needs to be confirmed with the user before follow-up work can be carried out to ensure service quality and service efficiency.

One detail is particularly important. Before the final installation is completed, the installer will perform special treatment on the connection of the high and low pressure pipes, and wrap the pre-prepared cushions at the connection. The purpose of this is to prevent condensation and reduce energy consumption to a minimum while playing a role in heat preservation. Through communication with the installer, this is one of the working standards set by Xiaomi, and the installer must follow the above operation methods!

The entire installation process took less than two hours, and the service quality can be called five-star. If netizens start in the futureXiaomi’s new first-class air conditionerWhether such high standards can be guaranteed remains to be seen.

Note: The specific installation tariff Xiaomi Mall has been announced in detail, please inquire from netizens.

Level 3 energy efficiency: Does it really cost electricity?

When buying an air conditioner, many people have considered whether to buy a third-level energy efficiency or a first-level energy efficiency. For consumers, the energy efficiency label must be a factor to consider. According to the current energy efficiency classification, it is divided into three levels: 1, 2, and 3. Many salespeople will instill in consumers that first-level and second-level products have good energy-saving effects, but for third-level energy-efficient products, the energy-saving effect is not ideal. Is that really the case?

The technology dog first calculates an account. At present, the cooling capacity of an air conditioner called 1 horse on the market is roughly 2300W, the positive 1 horse is 2500W, and the larger 1 horse is about 2600W. Based on the current energy efficiency rating, the first-level COP = 3.6, the second-level COP = 3.4, and the third-level COP = 3.2. On this basis, the respective power consumption is roughly as follows:

1 horse first power consumption = (2300/3.6) = 639W, second power consumption = (2300/3.4) = 677W; third power consumption = (2300/3.2) = 719W.

Positive 1 horse first power consumption = (2500/3.6) = 695W, second power consumption = (2500/3.4) = 735W; third power consumption = (2500/3.2) = 781W.

Large 1 horse first power consumption = (2600/3.6) = 722W, second power consumption = (2600/3.4) = 765W; third power consumption = (2600/3.2) = 813W.

Next, calculate the electricity bill. Based on the first-level energy consumption and the third-level energy consumption of an air conditioner, the difference between the two is 80W, the difference is 0.08 kWh in one hour, and the difference is 0.8 kWh in 10 hours a night. If the cost of 1 kWh of electricity is about 0.6 yuan, the electricity bill will be saved less than 50 cents a night. Assuming that the air conditioner is blown for 150 days a year, the electricity bill will be saved by about 70 yuan a year.

At present, the first-class energy-efficient air conditioners on the market are generally nearly 1,000 yuan more expensive than the third-class energy-efficient air conditioners, which means that the extra money can consume about 14 years of electricity bills, and the service life of an air conditioner is definitely not so long. Therefore, if the demand for air conditioners is not so strong, the third-class energy efficiency is more valuable than the first-class energy efficiency.

However, considering that some consumers need to heat up, or in the southern region, summer is usually longer, and the use of air conditioners is naturally longer. Therefore, such a situation can be purchased according to their own needs, or they can be based on the above calculation methods to estimate the general situation before making a decision.

Xiaomi’s new first-class energy efficiency air conditioner meets the national new first-class energy efficiency standards. Under the same conditions, it saves about 91 kWh of electricity a year and 45.5 yuan compared to the original first-class energy efficiency wall-mounted air conditioner. Vertical air conditioners can save up to 628 kWh of electricity a year.

The conclusion is actually very simple, three-level energy efficiency does not mean that it consumes a lot of electricity, and one-level energy efficiency means that it saves a lot of electricity, because the energy consumption performance should be comprehensively considered according to the actual use scenario and use time. It is recommended that netizens make multi-faceted comparisons on the Internet or brick and mortar stores, and choose suitable products to achieve twice the result with half the effort. Don’t lose confidence and mistake yourself.

Is Xiaomi’s new first-class air conditioner worth buying?

For Internet hardware to succeed, the most important point is still cost performance. In 2011, after the price of Xiaomi’s original mobile phone fell from the sky and caused a stir, hardware manufacturers under the banner of the Internet were not immune. Whether it is the mobile phone of the year, the later TV, or today’s air conditioner, Internet companies have entered the deeply rooted field of traditional manufacturers, and the only sharp knife is price. The new level of energy efficiency performance is cheaper and it provides six years of quality assurance time, which is comparable to the mainstream service of the industry. Xiaomi is quite sincere.

Air conditioners, TVs, refrigerators, washing machines, and Xiaomi TVs have made achievements. Xiaomi air conditioners may become another explosive product after Xiaomi TVs. Is it worth buying? Seeing that most netizens here are already well aware, will Xiaomi air conditioners recreate their brilliance? Let’s wait and see.
