1, patented cold expansion technology: patented cold expansion technology developed by using this principle, the expansion force of 1 gram of water freezing is as high as 960 kg per square centimeter, so that condensed water freezes and frosts on the radiator, and dirt can be easily peeled off by the expansion force;
2. Patented condensation technology: Haier patented condensation technology can increase the amount of condensed water, which is 30% higher than that of ordinary air conditioners. At the same time, frozen and frosted water will melt at one time, thus generating a lot of water and thoroughly washing off the peeling dirt;
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;
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 patented silver ion antibacterial technology, and the antibacterial rate is as high as 99.9% after testing by a third-party testing organization.
