Description

Technical Field

[0001] The utility model relates to the technical field of solubility testing equipment, in particular to a solubility testing device for refrigerants and refrigeration oils. Background Art

[0002] Refrigerant, commonly known as refrigerant, is a working fluid used to transfer heat energy and produce a freezing effect in refrigeration and air conditioning systems. It can be divided into primary refrigerant and secondary refrigerant based on its working method, and can be divided into natural refrigerant and synthetic refrigerant based on its material properties. Refrigeration oil is the oil used to lubricate the moving parts in the refrigeration compressor. In the compressor, refrigeration oil mainly performs functions such as lubrication, sealing, cooling and energy regulation.

[0003] When the physical and chemical properties test of refrigeration oil and refrigerant takes too long or the refrigeration oil and refrigerant are stored in the main tank, the boiling point of the liquid refrigerant is below zero and the main tank is in a high-pressure state. Due to the change in time, the ratio of refrigeration oil and refrigerant in the main tank will change, resulting in inaccurate test results. Sometimes the refrigeration oil and refrigerant are not completely dissolved, but are an emulsion. The denser side will sink, and the ratio will be inaccurate during the test. However, the main tank is a high-pressure tank with requirements for airtightness, and the stirring device cannot be directly inserted. In view of this, improvements are made to the existing problems and a refrigerant and refrigeration oil solubility test device is provided. Utility Model Content
