[0002] An air source heat pump is an energy-saving device that uses high-level energy to make heat flow from a low-level heat source, air, to a high-level heat source. It is a form of heat pump. As the name suggests, a heat pump is like a pump that can convert low-level heat energy that cannot be directly used, such as the heat contained in the air, soil, and water, into usable high-level heat energy, thereby saving some high-level energy, such as coal, gas, oil, and electricity. When an air source heat pump is used in a lower temperature environment, frost will form on its heat exchanger, affecting the quality of the air source heat pump.
