Abstract

The invention discloses a device and a method for measuring the solubility of a refrigerant in refrigerator oil and an application thereof. The device for measuring the solubility of the refrigerant in the refrigerator oil comprises a balance kettle device, a constant temperature device, a voltage divider, a flow collecting device and a refrigerant gas cylinder, wherein the balance kettle device comprises a balance kettle and a vacuum pump, and the vacuum pump is connected with the balance kettle; the constant temperature device comprises a constant temperature bath; the balance kettle is arranged in the constant temperature bath; the flow collecting device consists of a flower meter and a flow collecting system, and the flower meter is respectively connected with the balance kettle and the flow collecting system; and the voltage divider is arranged between the flow meter and the refrigerant gas bottle. The device has the advantages of simple structure, easiness in construction, low cost, short time required for gas and liquid balance; and the solubility of the refrigerant in the refrigerator oil can be quickly measured.

Description

technical field [0001] The invention relates to the technical field of testing devices, in particular to a device, method and application for measuring the solubility of refrigerant in refrigerating machine oil. Background technique [0002] The solubility of refrigerant in refrigerating machine oil is an important physical and chemical property. Determining the solubility of refrigerant in refrigerating machine oil is very helpful to understand the gas-liquid phase composition and saturated vapor pressure of the mixture of the two at different temperatures and pressures. It is of great significance to guide the development and design of compressors and the development of refrigerating machine oil. At present, developed countries and regions are stepping up the replacement of new refrigerants and the research and development of corresponding refrigeration oils. Facing the diversification of new refrigerants and the severe situation of research and development of refrigeratio...
