Abstract

The invention discloses a refrigerating system of three-stage flash-evaporation ejection economizers. The refrigerating system comprises an evaporator, a compressor, a condenser, a first-stage high-pressure flash-evaporation-tank economizer, a first-stage ejector, a second-stage flash-evaporation-tank economizer, a second-stage ejector and a third-stage economizer. The refrigerating system has a simple structure, high practicability and great using value, and is convenient to use; flash refrigerant steam produced by each stage of economizer is ejected and concentrated into a highest-pressure economizer and enters the compressor for compressing, and a liquid refrigerant produced by the economizers is ejected and concentrated into a lowest-pressure economizer and enters the evaporator for secondary evaporation, so that the refrigerating cycle efficiency of the economizers is remarkably increased.

Description

[0001] technical field [0002] The invention relates to the technical field of air conditioning and refrigeration systems, in particular to a refrigeration system of a three-stage flash ejector economizer. Background technique [0003] The economizer cycle is an effective way to improve the efficiency of the refrigeration system. This technology uses a flash tank or a heat exchanger economizer on the liquid refrigerant pipeline to introduce the throttling flash refrigerant vapor at the intermediate pressure of the refrigeration system to the middle of the compressor. The pressure economizer interface forms a close to multi-stage compression refrigeration cycle, which can improve refrigeration efficiency. In order to further improve the efficiency of the economizer, a multi-stage economizer can also be used to form a refrigeration cycle close to multi-stage compression. In addition, there is a large pressure difference energy between the condenser and the evaporator of the ...
