Abstract

The invention relates to the technical field of refrigerant test, in particular to a device and a method for measuring refrigeration oil and refrigerant mixed media. The device comprises a high-pressure sealed container comprising a pressure-resistant glass tube, a viscosity testing device comprises a capillary viscometer and a lifting device, the capillary viscometer is located inside the pressure-resistant glass tube, the lifting device comprises a magnet and metal, the magnet is arranged outside the pressure-resistant glass tube and capable of moving up and down along the tube wall, and the metal can drive a capillary viscometer to move up and down under the attraction action of the magnet. The device is simple, convenient to operate, safe and reliable, maximum borne pressure of the viscosity testing device depends on pressure bearing capacity of the sealed container of the high-pressure sealing device without being related to the capillary viscometer, and the device and the method can be used for measurement of liquid movement viscosity under a high-pressure state.

Description

technical field [0001] The invention relates to the technical field of refrigerant testing, in particular to a device and method for measuring the mixed medium of refrigeration machine oil and refrigerant. Background technique [0002] In the research field of alternative refrigerants, the solubility characteristics of refrigerants and corresponding refrigeration oils have been widely concerned. The air conditioning system generally requires that the refrigeration oil and the refrigerant have a certain compatibility. The compatibility between the two is good. The refrigerant dissolves in the refrigeration oil in a large amount, and the system returns oil quickly. However, another problem that may be caused is that the refrigerant will dilute the refrigerant. Oil, causing the viscosity of the mixture of the two to drop, which in turn affects its lubricating performance. In the face of the diversification of new refrigerants and the severe form of research and development of ...
