Air energy heat transfer system has become an important way of energy utilization in terms of new energy benefits because of its simple structure, low cost and stable movement.  Air energy refers to the low-grade thermal energy contained in the air.  According to the second law of thermodynamics, a low temperature heat source will not be transferred to a high temperature heat source without consuming external energy.  Heat pumps can absorb heat from the air and transfer it to high temperature objects or the environment, which is called air source heat pumps.  The air source heat pump realizes the transfer of heat energy by consuming electric energy or other energy to realize the utilization of air energy.  Therefore, the air source heat pump is not driven by air energy, but by electricity or other drives.  Air source heat pumps can be used for heating, heating, drying and other fields.

Air energy heat exchange system is mainly composed of air energy heat pump host and indoor unit.  Air energy heat pump hosts usually include compressors, evaporators, condensers and other components to absorb heat energy from outdoor air and raise it to a temperature suitable for heating through a circulation system.  Indoor unit: including indoor heat exchanger, fan, control system and other components, used to transfer the heat generated by the heat pump host to the room, and distribute the heat through the indoor pipeline system.
