When it comes to air conditioners that don't need electricity, what do you think of first?

The original ecological air conditioners invented by the African people in the above figure that use the “throttle effect”? Or is it a solar air conditioner that has been introduced by a domestic appliance brand?

In fact, none of them, friends who pay close attention to technology news should notice that the Dutch startup SoundEnergy launched a THEAC-25 cooling system using thermoacoustic effect at this year's CES show, which can directly convert waste heat into cold air. And the entire refrigeration process does not require refrigerant or precious metal materials, but the use of the most inert gas in the air - argon, is very environmentally friendly.

Legendary air conditioner

People's crazy pursuit of how to make electrical appliances useless electricity, the degree of obsession and the pursuit of perpetual motion by Europeans hundreds of years ago is exactly the same. The reason is that energy problems are becoming more and more serious. With air conditioning, there will be up to 6 billion air conditioners in the world by 2050, and they consume 37% of the world's electricity. Electricity consumption means that the home is warming all year round, and global warming people will cause the weather to be hot to encourage people to open air conditioners to cool off, which forms an infinite loop. So there is an urgent need to find new solutions, and SoundEnergy gives a good idea.

THEAC-25 thermoacoustic cooling system refrigeration principle

The mechanism for the mutual conversion of thermal energy and acoustic energy has only been obtained after centuries of exploration. Physicists have observed that when a hot bulb is attached to the end of an ice-cold glass tube, the air inside the glass tube expands and compresses, which in turn makes a sound, thus discovering the mystery of thermal and acoustic energy conversion.

The cooling device using the thermoacoustic effect is to generate a resonance sound wave in the resonance tube and work on the working gas in the tube, and the gas reciprocates to compress, expand and generate a temperature change, and then the cold air can be transmitted through the heat exchange.

The THEAC-25 thermoacoustic cooling system uses this principle. Argon gas is used as the heat exchange gas. The device absorbs heat and generates sound waves. The sound waves are continuously enhanced by the pressurization cycle, which causes the argon gas to generate a temperature gradient and finally converts the cold air. The refrigeration process does not use mechanical moving parts at all, and of course does not require electricity itself. It only needs to use industrial waste heat or solar energy to work.

What is life in the future?

The stunning appearance of the THEAC-25 thermoacoustic cooling system (airless air conditioner) has made the world feel that this is the future of home appliances. However, what is the future? Perhaps the upcoming AWE2019, known as the industry innovation vane, can give you some answers!

AWE, one of the world's three major home appliances and consumer electronics exhibitions

Whether it is the upcoming AWE2019 or the past CES show, intelligence is the only theme. Various manufacturers are also emphasizing smart homes and building their own smart home solutions.

Skyworth Smart Kitchen

Among them, Skyworth, a domestic traditional home appliance brand, will set up an experience zone on this AWE, allowing visitors to experience the “future life” at close range. Its smart Habitat solution not only realizes the interconnection between home appliances, Skyworth also provides personalized and customized services for users. For example, when the smart door lock recognizes the fingerprint of any member of the family, the indoor lighting system is immediately activated, the air conditioner is turned on to a comfortable temperature, the curtain is opened or closed according to personal habits, and the humidifier is automatically turned on.

Yunmi Whole House Internet Appliances

Yunmi is an Internet home appliance brand, and smart homes and smart home appliances are impressive. In this AWE2019, Yunmi started with the family scene, using AI and IoT as the core technology to create a matrix of all-home Internet home appliances, providing users with an integrated home Internet of things experience with multi-screen and multi-terminal.

Haier 'U+' platform

Haier's smart home platform 'U+' and TCL artificial intelligence platform TCLAL-IN are also expected to appear at the AWE2019 exhibition.

Haier's smart living room, the voice interaction of the TV can control other smart home appliances, and can also view the security of the whole house, air and other information. In the smart cloakroom, the 'Clothing Network' complete set of products such as smart washing machine, smart washing machine and smart fitting mirror can satisfy the user's whole process of washing, protecting, wearing, taking and purchasing clothes and shoes. Wisdom experience.

Haier smart kitchen solution, users can touch the screen hub to control the microwave oven, dishwasher, refrigerator and other appliances in the kitchen (via Wi-Fi or Bluetooth connection), but also can use it to buy daily necessities, real-time access to recipes, remote Video call and other operations.

From the last year AWE2018 can also see the 'future' development trend

In fact, as can be seen from last year's AWE2018, a single smart home appliance is no longer the mainstream, and the concept of 'all-room smart interconnection' has become popular. Yunmi brought 11 categories at the show last year, but a variety of new products, users can use the cloud meter V as the nerve center of the whole house smart connected appliances, users can use voice control, gesture control, face recognition and other technologies Communicate with it.

Yunmi Small V Smart Internet 'Nervous Center'

Summarizing the future life trends of AWE2018 to AWE2019, the intelligence is more reflected in the whole home environment, no longer just the intelligence of a certain product. From the smart products of the previous two years, the single intelligent hub, to the Internet of Everything, the concept of “central” has been weakened, that is, all the home appliances can be controlled by any product.
