The compressor absorbs low-temperature and low-pressure gaseous carbon dioxide refrigerant from the evaporator, and then compresses it into a high-temperature and high-pressure supercritical fluid. This fluid enters the gas cooler to exchange heat with water, where it is cooled into a high-pressure fluid and releases a large amount of heat. The water absorbs the released heat and the temperature continues to rise. After the high-pressure fluid is throttled and reduced in pressure by the expansion valve, it absorbs the heat in the surrounding air and evaporates into a low-pressure gas through the action of the fan in the evaporator, and is then sucked into the compressor for compression. This cycle is repeated to produce hot water .
Excellent high-temperature heating performance: the highest water output can reach more than 90’C.
Excellent low-temperature performance: high-temperature hot water can still be produced at an ambient temperature of -30°C.
First-level energy efficiency: high efficiency, standard COP not less than 4.6.
Wide application range: can work normally in an ambient temperature of -30’C43’C, suitable for producing domestic or industrial hot water In most parts of my country.
