7.5kw CO2 Heat Pump Air Source Water Source Residential Hot Water High Temp 90℃

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.
