Problems solved by technology

There are also some ejector design concepts, such as the Chinese patent (ZL 03136281.8) applied by Denso Co., Ltd., because considering that the nozzle and the diffuser section need to adapt to maintain a relatively high performance in a relatively wide range of medium flow, the design of the nozzle, The channel section adjustable mechanism of the diffuser has not been reported on its specific ejector performance, but this adjustable mechanism obviously brings about increased cost and complicated structure

Abstract

The invention discloses a vapor compression refrigerating system with ejector. It includes compressor, air-liquid separator, radiator, ejector and evaporator. The compressor outlet is connected with the radiator, the compressor inlet is connected with the air-liquid separator; the air-liquid separator is connected with diffusing section of the ejector via a valve; the valve is connected with controller; the radiator is connected with ejector nozzle via pipeline and is connected with first throttling element via the pipeline; the first throttling element is connected with the evaporator through pipeline and is connected with secondary throttling element and secondary one-way valve paralleled with the secondary throttling element to ejector suction chamber by pipeline; the evaporator is connected with the liquid end of air-liquid separator; the air end of air-liquid separator is connected with the compressor via pipeline.

Description

technical field [0001] The invention relates to a vapor compression refrigeration system, in particular to a vapor compression refrigeration system comprising an ejector, the system adopts the ejector as a vapor compression cycle of the main throttling element, and can be used in vapor compression refrigeration and heat pump devices . Background technique [0002] In the vapor compression cycle, after the refrigerant is compressed by the compressor, it is discharged into the condenser by the compressor, releases heat to a high-temperature heat source and condenses, and is throttled when it passes through a throttling element (such as a capillary tube, expansion valve). Both the pressure and temperature are reduced, and then enter the evaporator, absorb heat from a low-temperature heat source and evaporate, and finally re-enter the compressor to be compressed, completing a complete cycle. [0003] In 1966, C.A.Cemper of the United States applied for the patent No. US 3277660...
