Description

technical field

[0001] The invention relates to the field of heat pumps, in particular to a modular distributed air source heat pump unit. Background technique

[0002] The heat pump unit is a cycle system composed of compressor-condenser-throttle-evaporator-compressor and other devices. The refrigerant circulates in the system under the action of the compressor. It completes the process of increasing the pressure and temperature of the gaseous state in the compressor, and the temperature is as high as 100°C. After entering the condenser, it exchanges heat with the heat dissipation source to release heat. The refrigerant is cooled and converted into a high-pressure liquid state of about 1.5Mpa. When it runs to After the restrictor, the pressure suddenly drops to about 0.4Mpa. When it runs to the evaporator, the liquid state quickly absorbs the heat of the heat-absorbing source and evaporates, and then turns into a gaseous state again. At the same time, the temperature drops...
