The principle of self-cleaning air conditioner gives you the answer here.

1, patented cold expansion technology. As we all know, water expands when it freezes, so the heating pipes in the north and outdoors must be kept warm in winter, otherwise the pipes will burst once the water inside freezes; The patented cold expansion technology developed by using this principle, the expansion force of 1 g water is as high as 960 kg per square centimeter, which makes the condensed water freeze and frost on the radiator, and it is easy to peel off dirt by using the expansion force.

2. Patented condensation technology. Haier's patented condensation technology can increase the amount of condensed water, which is 30% higher than that of ordinary air conditioners. At the same time, it uses the accumulated water of ice and frost to melt at one time, thus producing a large amount of water and washing away the peeling dirt completely.

3. Patented sapphire blue coating technology. By coating a sapphire blue coating material on the surface of the heat sink, the hydrophilicity of hydrophilic aluminum foil can be improved by 50% and the water flow speed can be improved by 20%. The water flow speed of radiator using this patented technology is obviously higher than that of ordinary radiator, which can quickly wash away dust.

4. Patented antibacterial technology. Because the heat exchanger is often in a humid environment, it is easy to breed bacteria; Haier's patented antibacterial technology adopts the patented silver ion antibacterial technology. At the same time, Haier self-cleaning series air conditioners have specially added a "self-cleaning" button on the air conditioner remote control, which allows users to operate self-cleaning with one button, which is convenient and fast, and can ensure the healthy experience of air conditioners.
