Description

A heating and cooling multifunctional air source heat pump household unit

Technical Field

The utility model relates to the technical field of air source heat pumps, in particular to a multifunctional air source heat pump household unit for heating and cooling.

Background Art

The air source heat pump is driven by an electric motor. It uses the working principle of the vapor compression refrigeration cycle to produce cold or hot air or cold or hot water with ambient air as the cold or heat source. The air source heat pump uses the heat in the air as a low-temperature heat source, and exchanges heat through the condenser or evaporator in the traditional air conditioner. Then, through the circulation system, it extracts or releases heat energy, and uses the unit circulation system to transfer energy to the building to meet the user's needs for domestic hot water, floor heating or air conditioning. It is a multifunctional heat pump that can cool and heat. When the air energy heat pump is working, a lot of water droplets and water stains will be generated on the surface of the evaporator. If it is not cleaned for a long time, it is easy to enter the interior of the air energy heat source pump. At the same time, it will freeze and frost at low temperatures in winter, which will easily cause damage to the pump body and reduce the service life of the air heat pump. For this reason, a heating and cooling multifunctional air source heat pump household unit is proposed.
