Problems solved by technology

However, for fixed-frequency compressors, in the case of partial load, the required cooling capacity is actually less than that at full load, that is, the compressor does not need to be operated at full load. Down is actually a waste of energy

Abstract

The invention relates to frequency conversion type water cycle heat pump air conditioning unit in refrigeration technology field. It includes given frequency compressor, changed frequency compressor, oil separator, water-cooled condenser, liquid receiver, thermostatic expansion valve, refrigerant liquid supply tube, valve, evaporator, refrigerant liquid back tube, cooling tower, cooling water supply tube, supply valve, and back tube, water pump, and cooling water back valve. It adopts water cycle heat pump to improve refrigeration circular efficiency, and adopts two compressors according to demand.

Description

technical field [0001] The invention relates to a device in the technical field of refrigeration, in particular to a variable frequency water ring heat pump air conditioner unit. Background technique [0002] In the current social life, the air conditioner unit has also become one of the essential electrical appliances. Existing air-conditioning units are mostly air-cooled, and the efficiency of the refrigeration cycle is low, while the water-loop heat pump adopts water-cooling, which can reduce the condensation pressure and improve the refrigeration efficiency. [0003] After searching the literature of the prior art, it is found that the Chinese patent application number: CN01109633.0, publication number: CN1374482, this patent proposes "a heat pump air conditioner unit suitable for cold regions", which includes a compressor, a condenser, an expansion The valve and evaporator form a closed working cycle, and the system uses a scroll compressor. However, for fixed-frequen...
