Description

technical field [0001] The invention belongs to the technical field of heat pump systems, in particular to an air source heat pump energy station. Background technique [0002] Air-source heat pump units are also called air-cooled heat pump units, which is the general term for air-air heat pumps and air-water heat pumps. Its characteristics include: one machine with dual functions, with dual functions of cooling in summer and heating in winter; ambient energy is taken from the air in the natural environment, and there are few limiting factors for energy sources; easy to install, and can be placed in the open air on the top floor of the building or in an outdoor open space; Low investment, so it is widely used. [0003] However, at present, when the air source heat pump system is used for heating, the ambient air heat exchanger adopts air-refrigerant liquid-vapor phase change to directly exchange heat, and the refrigerant liquid-vapor phase change absorbs a lot of heat per u...

AI Technical Summary

Problems solved by technology

The upscaling of traditional air source heat pumps is achieved through the simple parallel connection of a large number of such single units. The upscaling is the simple superposition of small modules. The stop / start of the machine corresponds to the stop / start of the air-refrigerant liquid-vapor phase change heat exchanger. When the large-volume air-refrigerant liquid-vapor phase change heat exchanger is in an unsaturated operating state, its excess The heat exchange capacity has not been fully utilized, so the large-scale has not brought the corresponding scale effect

Moreover, a large-volume air-refrigerant liquid-vapor phase conversion heat exchanger and a small-volume, high-power compressor are combined into a module, and a protective shell is added, which can easily cause resonance in the cavity; at the same time, a large-scale unit is formed The protective shell also limits the unit layout, location and space selection, and it is easy to produce the hot and cold island effect
