Haier self-cleaning air conditioner has four patented technologies: 1. Patent cold expansion technology II. Patented condensed water technology. Patent sapphire blue coating 4. Patented antibacterial technology. Its working principle is as follows: In the traditional air conditioner, the condensed water of the evaporator is directly discharged by the drain pipe. Haier Air Conditioning found that if the condensed water on the evaporator frosts and freezes, each gram of water can generate an expansion force of 960 kg/cm2. In the process of water freezing, like the high temperature in summer, melted chocolate easily sticks to the wrapping paper. If you put the chocolate in the refrigerator and then take it out, the wrapping paper will be clean after peeling! This is the principle of Haier's self-cleaning air conditioning cold expansion technology to strip dirt.
