Air-conditioning plant using heated water and heating pump

Abstract

Disclosed is a hot water heat pump air conditioning, comprising heat recovery device with input tube (10) and output tube (13) linked in series between the outlet of compressor (1) and high pressure side inlet of four-way valve (8) , bypass fluid control pipe (3) with one end linking to the compressor (1) and another end to the high pressure air side control pipe inlet of four-way valve (8). The invention has realized excellent refrigeration and heating effect of air condition and heat recovery ensured each part operate stably, and it has simple structure low cost convenient manufacture.

Description

technical field [0001] The invention relates to various large, medium and small air-conditioning heat pump refrigeration devices, in particular to a hot water heat pump air-conditioning device that recycles condensation heat.

Problems solved by technology

At present, there are a large number of heat pump / air-conditioning refrigeration equipment of various capacities in China, such as household air conditioners, large and medium-capacity refrigeration / heat pump devices, etc., and their structures are composed of compressors, four-way valves, condensers, dry filters, evaporators, liquid storage The four-way valve is composed of a pneumatic control tube used to control the reversing of the four-way valve spool. The inlet of the pneumatic control tube is connected to the inlet of the four-way valve and then connected to the outlet of the compressor. Most of the condensers of the air conditioner It adopts single air cooling or water cooling. When cooling in these ways, a large amount of heat is directly discharged into the atmosphere, which not only pollutes the environment (thermal pollution), but also wastes energy. The condensation heat released into the air cannot be recycled.

Similar products at home and abroad have disadvantages such as complex refrigeration process transformation, frequent replacement of components, which is not conducive to production and processing
