Stacked sleeve type condenser

Abstract

The invention discloses a stacked sleeve type condenser, and relates to the technical field of vapor compression type refrigerating systems. The stacked sleeve type condenser comprises a condenser body, an outer sleeve is arranged outside the condenser body, a lining pipe is installed inside the outer sleeve, the outlet end of the condenser body is sequentially connected with a throttling device,an evaporator and a compressor, the outlet end of the compressor is connected with the inlet end of the condenser body to form a circulating refrigeration system, the circulating refrigeration systemis filled with a refrigerant, the refrigerant flows out of the outlet end of the compressor, sequentially flows through the condenser body, the throttling device and the evaporator and flows into theinlet end of the compressor, and the lining pipe is arranged at the outlet end of the outer sleeve. According to the stacked sleeve type condenser, by arranging the lining pipe inside the outer sleeveof the condenser body, the internal volume is reduced while the heat exchange area of the condenser body is not reduced, the effective refrigeration time is prolonged, and the efficiency of a refrigeration system is improved.

Description

technical field [0001] The invention belongs to the technical field of vapor compression refrigeration systems, and in particular relates to a laminated casing condenser. Background technique [0002] The vapor compression refrigeration system is a closed circuit. The compressor drives the refrigerant to circulate in the condenser, capillary, evaporator, return pipe and other components in order to transfer heat. The condenser is a heat-releasing part. The compressor inputs the high-temperature and high-pressure gaseous refrigerant into the condenser. Through the heat exchange between the condenser and the outside world, the internal refrigerant gradually condenses from gaseous state to liquid state. As the phase state of the refrigerant changes, The flow rate of the refrigerant gradually decreases. [0003] Refrigerators and air conditioners are vapor compression refrigeration systems. The compressors are turned on and off periodically to control the constant temperature i...

Problems solved by technology

[0004] Under the same conditions, the larger the surface heat exchange area of ​​the condenser in the refrigeration system, the higher the efficiency. Although increasing the diameter of the condenser pipe can increase the heat exchange area, the increase in the diameter of the pipe will reduce the flow rate of the refrigerant and dissolve in the refrigeration system. The refrigerating oil in the refrigerant will suffer from oil separation when the flow rate is lower than the rated flow rate. Too much refrigerating oil in the condenser will reduce the heat transfer efficiency of the refrigeration system. Therefore, a condenser is required without reducing the heat transfer of the condenser. Reduce the internal volume while reducing the area, prolong the effective refrigeration time, and improve the efficiency of the refrigeration system
