What is SUNCHI ENERGY Carbon Dioxide/CO? Heat Pump:
The DC inverter compressor sucks the low-temperature and low-pressure gas CO?Refrigerant from the evaporator,
and the CO?Refrigerant compresses into a high-temperature and high-pressure supercritical fluid .
The fluid enters the gas cooler and exchanges the heat with cold water, and is cooled to a high pressure fluid in the gas cooler.
The fluid thus releases a large amount of heat, and the cold water absorbs the released heat so that the water temp. is higher
After the high-pressure fluid is throttled and depressurized by the electronic expansion valve, which absorbs the heat in the air around of the heat pump by fan running In the evaporator, and evaporates into a low-pressure gas, which is again sucked into the compressor for compression work, so that the Refrigerant cycle is repeated to obtain high-temperature hot water.
