Non-condensable gas purification device, refrigeration system and method

Abstract

The invention provides a non-condensable gas purification device, a refrigeration system and a method. The non-condensable gas purification device comprises a separation device and a control device, wherein a connection pipeline is arranged between the separation device and a refrigerant circuit of the refrigeration system, and the separation device can extract mixed gas of non-condensable gas anda gaseous refrigerant in the refrigerant circuit and condenses the gaseous refrigerant in the mixed gas into liquid to be separated out; and the control device comprises a detector and a switch part,wherein the detector is installed on the refrigerant circuit and automatically detects whether the non-condensable gas exists in the refrigerant circuit or not, the switch part is installed between the separation device and the refrigerant circuit, and the switch part controls the communicating or non-communicating of the connection pipeline according to a detection result from the detector. Thenon-condensable gas purification device can effectively solve the problem that the system energy efficiency is reduced due to the fact that the non-condensable gas easily enters the low-pressure refrigeration system, the application range of the device is wide, the non-condensable gas purification requirement of the system can be quickly identified, the system can be rapidly purified in time, andthe efficient and reliable operation of the refrigeration system is ensured.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a non-condensable gas purification device, a refrigeration system and a method. Background technique [0002] For refrigeration systems using low-pressure refrigerants, because the working pressure is lower than atmospheric pressure, the air in the atmosphere will penetrate into the refrigeration system through various gaps, such as valves, compressors, pipelines and other sealing parts. The infiltrated non-condensable gas not only seriously affects the heat transfer efficiency of heat exchange equipment, but also increases the power consumption of power equipment such as compressors and water pumps, reducing the energy saving level of products. Seriously, the exhaust pressure of the compressor increases, which increases the force acting on the bearings, sliding surfaces and other parts, which may accelerate the loss of mechanical equipment, and even cause the c...
