Problems solved by technology

Since this refrigeration cycle system does not have a heat exchange device, when the air conditioner is running under low load, the refrigerant flowing out of the evaporator will not be completely evaporated, which will cause liquid shock in the compressor
In addition, in order to condense all the refrigerant, the heat exchange area of ​​the condenser must be large enough, which will undoubtedly increase the volume of the outdoor unit and heat up a large amount of air around the outdoor unit.

Abstract

The present invention discloses a regenerative refrigeration cycle system air conditioner. It includes compressor, condenser, throttle device, evaporator and recuperative heat exchanger. The described recuperative heat exchanger includes a cylindrical tank body whose top portion and bottom portion are respectively equipped with low-pressure refrigerant outlet and inlet connected with compressor suction pipe and evaporator outlet, a straight tube which is placed in the interior of tank body along vertical direction and whose upper and lower ends are respectively connected with condenser outlet and throttle device and a heat-exchanging coiled tube, said coiled tube and straight tube are integrally formed into one body.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an air conditioner with a regenerative refrigeration cycle system. Background technique [0002] Generally, an air conditioner is a device that makes the refrigerant inside it undergo a refrigeration cycle consisting of a compression process, a condensation process, an expansion process, and an evaporation process. In the air conditioner, the refrigerant that has been compressed into a high-temperature and high-pressure state can dissipate heat to the outside in the condenser, and when it flows through the throttling device, its temperature and pressure are significantly reduced, and then the low-temperature, low-pressure refrigerant flows through the evaporator It absorbs heat and eventually flows back into the compressor. Among them, the compression process, condensation process and expansion process are carried out in the outdoor unit of the air conditioner, while the evaporation process...
