　　The swimming pool heat pump is an air source heat pump designed by the air energy manufacturer specifically for swimming pools. Its working principle is the same as that of ordinary air source heat pumps. The difference between the two is:pass heat pumps for sale It can be seen from the present situation that the market prospect is relatively broad, which is conducive to our reference and investment. http://mangoenergyheatpump.com

　　Ordinary air source heat pumps are mainly used for domestic hot water heating, while swimming pool air source heat pumps are dedicated to constant temperature heating of swimming pools. The heat exchanger is made of special pure titanium tubes with good corrosion resistance. Because swimming pools need to be cleaned by adding chemicals, ordinary heat pumps will quickly corrode the heat exchanger. In the past, swimming pools liked to use coal/gas/oil, electric boilers and other equipment to provide hot water, but in recent years, with the country’s attention to environmental protection and other issues, coupled with the shortcomings of coal/gas/oil, electric boilers and other equipment themselves, such as unsafe, high pollution and high cost, more and more swimming pools and swimming pools have begun to choose new hot water equipment to provide hot water for swimming pools. Among them, swimming pool air source heat pumps have become the object of constant temperature pursuit of villa swimming pools, swimming pools, and fitness clubs.

Moreover, there is no pollutant emission to the environment during use, no environmental pressure, and it meets national environmental protection requirements. There is no need to face annual inspections by boiler-related departments.

　　

　　2. It is more energy-efficient and saves more money. The heating efficiency of ordinary air-energy heat pumps is generally 400%, which is four times that of ordinary electric water heaters. However, because the swimming pool air-energy heat pump can control the temperature at only 28＜C, which is lower than the outlet water temperature of ordinary air-energy heat pumps, the heating efficiency is as high as 520%, which is more energy-efficient.

　　

　　3. Accurate temperature control and more comfortable. The air-energy swimming pool constant temperature system has a wider temperature operation range (ambient temperature range -25-43＜C, water temperature control range 20-55＜C), and can automatically adjust the flow rate according to ambient temperature, water temperature and other data to ensure stable and efficient operation of the unit. And it is not affected by natural climate such as wind, light, rain, and snow, and can achieve constant temperature of the swimming pool throughout the year.
