What is the Electric Auxiliary Heating of Air Source Heat Pump?

The electric auxiliary heating of air source heat pump is an auxiliary heating technology, which is mainly used in heat pump water heaters (air source heat pumps). Its main function is that when the external ambient temperature is too low, when the heat in the air is not enough to quickly heat the water, the electric auxiliary heating function can be started to supplement the deficiency of the air source heat pump, thereby ensuring the stability and timeliness of hot water supply.

The working principle of the air source heat pump is to absorb the heat energy in the air through the operation of the compressor to increase the water temperature. However, when the ambient temperature is low, the heating efficiency of the air source heat pump will drop significantly, and it may even stop running. In this case, the electric auxiliary heating function can improve the heating efficiency through additional electric heating to ensure that enough hot water can still be provided under extreme low temperature conditions.

Electric auxiliary heating technology usually adopts PTC (positive temperature coefficient) electric auxiliary heating technology, which can automatically adjust the heat output according to the changes in room temperature and the size of the indoor unit air volume, so as to achieve the purpose of rapid and strong heating. In addition, electric auxiliary heating can also shorten the heating time and improve the overall efficiency of the system.

Therefore, electric auxiliary heating of air source heat pump is an important technology to improve the heating efficiency of air source heat pump in low temperature environment. It uses electric heating as an auxiliary means to ensure that users can still get sufficient hot water supply in winter or other low temperature conditions.
