Abstract

The invention belongs to the field of compression refrigeration equipment, and particularly relates to a thermal insulation device for MRC two-stage compression mixed refrigeration; it includes a circulation component, a thermal insulation component and a detection component; the circulation component, the thermal insulation component and the detection component are all arranged in a columnar structure; the A first solenoid valve is arranged inside the circulation assembly; the heat preservation assembly is arranged on the upper end of the circulation assembly, and a third cavity and a fourth cavity are arranged inside the heat preservation assembly, and the third cavity and the fourth cavity are mutually Isolation; the present invention adds the heat preservation device to the existing two-stage compression refrigeration system, and the heat preservation device can form a group of open and closed loops with the compression link in the two-stage compression refrigeration system, and stop working in the two-stage compression refrigeration system Afterwards, the open-close circuit operates, and the compressed gas in the circuit is compressed and stored, so that the refrigeration system can be opened and used at any time without preheating, and the use is quick.

Description

A kind of thermal insulation device for MRC two-stage compression mixed refrigeration technical field The invention belongs to the field of compression refrigeration equipment, particularly a kind of thermal insulation device for MRC secondary compression mixed refrigeration. Background technique Two-stage compression refrigeration is to divide the compression process into two times to realize, to be about to evaporate the low-pressure refrigerant output from the evaporator. The gas is first compressed to the intermediate pressure with the low-pressure compressor, and then compressed to the condensing pressure with the high-pressure compressor. Existing secondary compression refrigeration system consists of evaporator, condenser, intercooler, low pressure compressor and high pressure compressor group The working process is as follows: the steam flowing out from the evaporator is sucked by the low-pressure compressor, compressed to the intermediate pressure, and flows w...
