Air source heat pump is one of the commonly used energy-saving technologies recently. The refrigerant (R22, R417A, etc.) in the air source heat pump water heater absorbs the low-temperature heat energy in the air, converts it into high-temperature heat energy after being compressed by the compressor, and then is used to heat the water temperature. This air source heat pump water heater has the characteristics of high efficiency and energy saving. It uses only 1 / 4 of the electric energy to carry the free heat energy of the external air indoors. Its energy saving effect is 4 times that of the electric water heater, 3 times that of the gas water heater and about 2 times that of the solar water heater.
