Why is Haier's self-cleaning air conditioner so magical?

Haier self-cleaning air conditioner has four patented technologies: 1 cold expansion technology: it has an expansion force of 960kg/cm2, which is the expansion force after water freezes, and this force is very strong. By quickly collecting water vapor in the air, it condenses into frost and freezes, and the dirt on the evaporator is stripped by cold expansion technology. 2. Condensed water technology: high strength and large amount of water. Condensed water technology increases 30% of condensed water with large amount of water, which effectively washes the dirt in the heat exchanger. Sapphire coating: Haier patented sapphire coating, the hydrophilicity is increased by 50%, the water flow speed is increased by 20%, and it is more antibacterial and decontamination.
