Abstract

The ejector attached self cascade refrigeration circulating system comprises a pipes connected compressor, a condenser, a gas and liquid separator, an evaporation condenser, an evaporator, and an inflated valve with ejectors between the evaporating condenser and the evaporator. The outlet of the compressor connects with the inlet of the condenser whose outlet connects with the inlet of the gas and liquid separator and the gaseous coolants of the outlet of the gas and liquid separator connecting with the inlet of the evaporating condenser, the other liquidized coolant connecting with the evaporating condenser through the inflated valve. One of the branches of the outlet of the evaporating condenser enters into the evaporator through the inflated valve; the other branch of coolant vapor enters into the ejector as the working vapor, with the outlet of the ejector connecting with the inlet of the compressor.

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 self-cascading refrigeration cycle system with an ejector. Because the ejector is used in the cycle system, the suction pressure of the compressor can be increased. Reduce the pressure ratio of the compressor; reduce the pressure drop of the expansion valve; reduce the heat transfer temperature difference in the evaporative condenser. Thereby reducing the irreversible loss in the cycle and improving the performance of the circulatory system. It can be used in low temperature refrigerators, low temperature coolers and gas liquefaction equipment. Background technique [0002] The self-cascade refrigeration system is a refrigeration cycle system using multiple mixed working fluids. It uses a single compressor to achieve high-boiling-point components and low-boiling-point components through self-separation and ...
