Problems solved by technology

At a certain evaporating temperature (that is, the refrigeration temperature requirement), when the ambient temperature is constant, increasing the exhaust pressure can improve the performance of the circulation system; but the higher the pressure ratio of the compressor, this will reduce the efficiency of the compressor and increase the efficiency of the system. The irrev...

Abstract

The invention discloses a small-scale throttling low-temperature refrigerator circulation system with an ejector, which comprises a compressor connected to a pipeline, a cooler, two regenerators and a throttle valve. Another ejector is further arranged between a second regenerator and an evaporator. By utilizing the effects of expansion and pressurization of the ejector, the invention can enhance the suction pressure of the compressor, lower the pressure ratio and the air absorption ratio capacity of the compressor, thus correspondingly lowering the unit power consumption of the compressor and enhancing the gas transmission rate of the compressor, increasing the cooling capacity of the system and enhancing the performance coefficient of the system. On the other hand, the ejector is adopted to result in that the heat exchange water equivalent of two sides of the regenerator is more matched, thus improving the heat recovery process and reducing the irreversible loss in the heat recovery process. Thereby, the small-scale throttling low-temperature refrigerator circulation system with an ejector has obvious advantages with respect to improving the performance of the throttling refrigeration system.

Description

technical field [0001] The invention belongs to the technical field of refrigeration and low temperature, and relates to a refrigeration cycle system, in particular to a small throttling low-temperature refrigerator cycle system with an ejector. The cycle system can increase the suction pressure of the compressor due to the use of the ejector , reduce the pressure ratio of the compressor, increase the air delivery capacity of the compressor; thus reduce the unit power consumption of the compressor, increase the cooling capacity of the system, and improve the performance of the circulation system. It can be applied to the cooling of low-temperature refrigerators, medical low-temperature refrigeration equipment and electronic equipment. Background technique [0002] Small throttling cryogenic refrigerators are widely used in space refrigeration, electronic device cooling and medical cryogenic refrigeration equipment and other fields. It has the characteristics of simple and c...
