Abstract: The cooling effect of the condenser of household air conditioner is directly related to the working efficiency of air conditioner. Using the condensate produced by air conditioner to cool the condenser can not only improve the refrigeration coefficient, but also reduce the random discharge of condensate. The developed condensing water recovery device improves the heat exchange effect of the condenser and reduces the starting times of the air conditioner. Taking the household air conditioner as an example, it can save about 220 yuan of electricity every year. It is easy to install and low in price, so it has a broad application prospect.

Key words: Condensate recovery, Atomizer, Special water pipe for air conditioning, Condensate tank, Coefficient of refrigeration
