A refrigerant purification equipment

Abstract

A refrigerant purifying device comprises a high-pressure gas-liquid separator (21), a coiled pipe type evaporation and condensation heat exchanger (41) and an evaporation chamber (42), wherein the high-pressure gas-liquid separator (21) is connected with the coiled pipe type evaporation and condensation heat exchanger (41) through a pipe, the high-pressure gas-liquid separator (21) is located under the connecting position of the high-pressure gas-liquid separator (21) and the coiled pipe type evaporation and condensation heat exchanger (41), and the coiled pipe type evaporation and condensation heat exchanger (41) is located in the evaporation chamber (42) and is of a zigzag coil structure uniform in thickness. The refrigerant purifying system is an energy-saving device connected with a refrigeration system pipeline to separate and discharge oil, non-condensable gas and moisture in the refrigeration system under the interaction of high-pressure gas and low-pressure liquid. The coiled pipe type evaporation and condensation heat exchanger housing used by the device is full in turbulence and high in heat exchange efficiency and lower in ammonia and oil loss.

Description

technical field [0001] The invention relates to a refrigerant purification device. Background technique [0002] The existing RPS series refrigerant purification equipment can have the function of separating and removing non-condensable gases such as air, moisture and oil in the refrigerant running in the refrigeration system. Using Chinese man-machine interface, the operation is simple and convenient. Thereby improving cooling efficiency and reducing energy consumption. Through the examples of many factories, we found that quite a few factories use the method of opening the vent valve to directly discharge to the pump to reduce the condensing pressure. This method is wrong. Because the manual discharge does not go through the low temperature condensation process, more than 90% of the discharged gas is ammonia refrigerant gas, and only a small part of the air is discharged along with it. The drainage and oil discharge are also manual discharge, which is not only dangerous ...

AI Technical Summary

Problems solved by technology

Because the manual discharge does not go through the low-temperature condensation process, more than 90% of the discharged gas is ammonia refrigerant gas, and only a small part of the air is discharged. The drainage and oil discharge are also manual discharge, which is not only dangerous but also very inefficient.
