Description

Technical Field

[0001] The invention relates to the technical field of air source heat pumps, in particular to a full air circulation cold and heat exchange air source heat pump control system. Background Art

[0002] Air source heat pump is an energy-saving device that uses high-level energy to make heat flow from low-level heat source air to high-level heat source. It is a type of heat pump technology and is known as "the transporter of nature's energy". It has multiple advantages such as low cost, easy operation, good heating effect, safety and cleanliness.

[0003] CN214701320U proposes an air source heat pump system, including more than two outdoor heat exchangers, wherein the outdoor heat exchanger is divided into a preheating heat exchanger and a common heat exchanger, one side of the preheating heat exchanger is connected to the indoor heat exchanger and the refrigerant discharged from the indoor heat exchanger can flow directly to the preheating heat exchanger without throttling. The system can achieve a relatively good defrosting effect.

[0004] However, the existing technology still has certain defects when applied. When the existing technology is applied, the heat exchange effect between the evaporator and the outside air is mainly improved by the fan, but the continuous operation of the fan will undoubtedly increase the energy consumption of the equipment.
