Principle Introduction of 7.5kw CO2 heat pump air source water source residential hot water high temperature 90℃

The compressor sucks low-temperature and low-pressure gas carbon dioxide refrigerant from the evaporator, and compresses the carbon dioxide refrigerant into a high-temperature and high-pressure supercritical fluid through work. The high-temperature and high-pressure supercritical fluid enters the gas cooler to exchange heat with water, and is cooled in the gas cooler. The high-pressure fluid releases a lot of heat, and the water absorbs the heat released and the temperature continues to rise. After the high-pressure fluid is throttled and depressurized by the expansion valve, in the evaporator, the fan absorbs the heat in the surrounding air and evaporates into low-pressure gas, which is sucked into the compressor and compressed, so that it is repeatedly circulated to provide hot water.

Features of 7.5kw CO2 heat pump air source water source residential hot water high temperature 90℃
