Air source heat pump is a heat pump that uses air as a low-temperature heat source to produce hot water. It is mainly composed of air source heat pump circulation system and water storage tank. The air source heat pump water heater is a kind of equipment to produce hot water by consuming part of electric energy and transferring the heat in the air to the water. It can also replace the energy-saving and environment-friendly hot water supply device that the boiler is not limited by resources. It uses green and pollution-free cold coal to absorb the heat in the air, and through the work of the compressor, it can produce more than 50 degrees of domestic hot water. The annual C.O.P value reaches more than 3.0.

The energy saving effect of heat pump is outstanding, the return on investment period is short, and the air source heat pump can save 70% of energy; Compared with the solar water heater with gas, electricity and electric auxiliary heating, the annual cost is the lowest, which is less than the solar water heater (with auxiliary electric heating), about 1/3 of the gas water heater and about 1/4 of the electric water heater. Short term recoverable investment. Each 1kw of power consumption can produce 4kw of heat energy on average, and the same power consumption is about 3 times more than that of electric hot water boiler.

Moreover, the air energy heat pump has a good control system and a heat storage tank, which can achieve sufficient water supply every day and meet the needs of daily peak water supply. It is equipped with liquid level and temperature control to ensure that the heat pump starts to heat when the water temperature is low; When the liquid level is low, the cold water will be replenished automatically; More hot water can be regulated and stored by the heat storage tank; If the return water temperature of the system is low, the circulating water pump and the heat pump will automatically start to reheat the stored warm water. If the outlet water temperature is too low for a long time, the auxiliary electric heater can be started for short-term heating. Therefore, the water supply temperature of the heat pump hot water system is stable and reliable, the water supply is sufficient, and the water supply quality is guaranteed.
