Description

Technical Field

[0001] The utility model relates to the technical field of air source heat pumps, in particular to a heat preservation device for an air source heat pump. Background Art

[0002] An air-source heat pump is a motor-driven device that utilizes the principle of a vapor-compression refrigeration cycle to produce cold (hot) air or water using ambient air as a cold (hot) source. Its main components include a heat exchanger on the heat-using side, a heat exchanger on the heat-source side, and a compressor. Air-source heat pumps utilize the heat in the air as a low-temperature heat source, exchanging heat through the condenser or evaporator in a traditional air conditioner. This heat is then extracted or released through a circulation system, which then transfers the energy to the building, meeting user needs for domestic hot water, floor heating, or air conditioning.

[0003] During and after the heat exchange process, in order to effectively maintain the temperature of the liquid inside the water tank and reduce heat loss and energy waste, effective insulation measures must be taken. However, when improving the insulation effect, the efficiency of the water tank and the heat exchange device still needs to be guaranteed. The traditional insulation measure for the water tank is simply to cover the outside of the water tank with an insulation layer, which cannot take into account both the insulation effect and the equipment efficiency. Therefore, an insulation device for an air source heat pump is proposed to solve the above problem. Utility Model Content
