Technical Field

Background
The air source heat pump is used as modern high-efficiency energy-saving heat supply and refrigeration equipment, and when the heat pump operates in a low-temperature environment, fins on the surface of a heat exchanger of the heat pump are prone to forming frost. The formation of frost not only reduces the heat exchange efficiency, resulting in reduced performance of the heat pump system, but may also increase energy consumption and even cause equipment failure, severely affecting its stability and service life. To cope with this problem, the conventional defrosting methods mainly include electric heating defrosting, reverse circulation defrosting, natural melting defrosting, and the like.
Electric defrosting is a relatively straightforward and widely used defrosting mode. The principle is that by installing an electric heating element near the heat pump fin or on the surface, when detecting that the ambient temperature falls below the preset frosting temperature, the control unit starts the electric heating element to electrify, and the frost on the fin is directly melted by the heat generated by the electric heating element. However, the electric defrosting mode has a significant energy consumption problem. On the one hand, the electric heating element consumes a great deal of electric energy during operation, and particularly in the case of long-time or frequent defrosting, the operation cost of the heat pump system is increased significantly. On the other hand, the heat generated in the electric heating defrosting process is often not fully utilized, and part of the heat can be dissipated into the air, so that the energy efficiency is low.
