What is the difference between the self-cleaning technology of Haier air conditioner and other brands of air conditioners?

Haier's self-cleaning air conditioner can thoroughly clean the heat exchanger of air conditioner and ensure air health by using four patented technologies: cold expansion patent technology, condensation patent technology, sapphire coating patent technology and antibacterial patent technology. 1, patented cold expansion technology As we all know, the volume of water expands when it freezes, so the heating pipes in the north and outdoors must be insulated in winter, otherwise the pipes will burst once the water inside freezes; The patented technology of cold expansion developed by using this principle, the expansion force of 1 g water freezing is as high as 960 kg per square centimeter, which makes the condensed water freeze and frost on the radiator, and the dirt can be easily peeled off by using the expansion force; As shown below, on the left is an ordinary air conditioner, and the dirt attached to the heat sink for a long time cannot be washed away by condensed water; On the right is Haier's self-cleaning technology, which uses the expansion force of water freezing and frosting to peel off dirt and solve the problem that dirt is difficult to peel off; 2. Patented condensation technology As can be seen from the comparison chart on the right, the amount of condensed water used in ordinary air conditioners is less, while Haier patented condensation technology can increase the amount of condensed water by 30% compared with ordinary air conditioners, and at the same time, by freezing frosted water and melting it at one time, a large amount of water is generated, and the peeling dirt is completely washed away; 3. Patented sapphire coating technology By coating a layer of sapphire coating material on the surface of the heat sink, the hydrophilicity of hydrophilic aluminum foil can be increased by 50%, and the water flow speed is increased by 20% compared with the original one; As can be seen from the right picture, the water flow speed of the radiator using this patented technology is obviously higher than that of the ordinary radiator, which can quickly wash away dust; 4, patented antibacterial technology heat exchanger is often in a humid environment, it is easy to breed bacteria; Haier's patented antibacterial technology adopts patented silver ion antibacterial technology, and the antibacterial rate is as high as 99.9% after testing by a third-party testing organization. Compared with ordinary air conditioners, the antibacterial rate of ordinary air conditioners is almost zero. 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.
