Problems solved by technology

[0004] The efficiency of the traditional jet refrigeration system is low, and the circulation pump, the only moving part, still needs to consume a certain amount of electric energy. Further improving the efficiency of the jet refrigeration system and reducing the power consumption of the system are of great significance to the development of jet refrigeration technology.

Abstract

The invention discloses a spray refrigeration system capable of recovering condensation heat and a method thereof, belonging to the technical field of low-grade energy utilization. The system includes generator, gas injector, evaporator, condenser, circulation pump and throttling device. On the basis of the traditional injection refrigeration system, a gas injector is added to inject part of the condensed gas leading to the condenser, and the gas is injected through the gas to recover part of the heat of condensation, reducing the heat load and area of ​​the condenser, The thermal load and area of ​​the generator are further reduced. Under the same cooling load, the fluid flow through the circulation pump is reduced, thereby reducing the power consumption of the circulation pump, and thus improving the thermal performance of the ejector refrigeration system. The utility model has a simple structure, greatly improves the performance of the jet refrigeration system, that is, improves the efficiency of the jet refrigeration system, reduces the electric energy consumed by the system, and has wide practicability in the technical field.

Description

technical field [0001] The invention relates to a refrigeration system and a method thereof, in particular to a jet refrigeration system and a method suitable for low-grade energy utilization and capable of recovering condensation heat. Background technique [0002] my country's industrial waste heat is rich in resources, has great potential for utilization, and is widely distributed. A lot of waste heat has high temperature and stable heat carrier flow, which has good utilization conditions, but the utilization efficiency is extremely low. The ejector refrigeration device can use low-grade energy such as industrial waste heat as a driving source, which can effectively improve energy utilization and help to solve the problem of energy shortage. The ejector refrigeration system is an environment-friendly refrigeration system, which has the advantages of simple structure, few moving parts, and low operation and maintenance costs. The ejector refrigeration system has been iden...
