Title:
SIPHON EVAPORATION DEVICE HAVING HEAT EXCHANGE STRUCTURE, AND OPERATION METHOD AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/065600
Kind Code:
A1
Abstract:
The present invention relates to the technical field of absorption refrigeration. Provided are a siphon evaporation device having a heat exchange structure, and an operation method and application thereof. The siphon evaporation device comprises an evaporator and a heat exchanger. The heat exchanger is located above the evaporator. A liquid refrigerant outlet at the lower end of the heat exchanger is connected to a liquid refrigerant inlet at the upper end of the evaporator. A gaseous refrigerant outlet at the upper end of the evaporator is connected to a gaseous refrigerant inlet at the lower end of the heat exchanger. A liquid refrigerant passes through a heat exchange tube pass of the heat exchanger. A tail end of the heat exchange tube pass enters a shell pass of the heat exchanger from the bottom of the heat exchanger through a pressure reduction pipe. The gaseous refrigerant outlet is further formed on the heat exchanger. Compared with an absorber structure in the prior art, the heat exchanger is used for replacing an original gas-liquid separator, a supercooling degree of the refrigerant before entering the evaporator can be increased, the superheat degree of refrigerant steam at the refrigerant outlet is improved, the refrigerating capacity of the refrigerating system is improved, and the COP of the refrigerating system is increased. In an absorption refrigeration system, a precooler is reduced, and the process complexity is reduced.
