Embodiment Construction

[0030] For ease of understanding, the combination of refrigerant R32 and Figure 1-3 Specifically set forth the component structure of the present invention and its specific working process; R32 is a hot spot refrigerant replaced by HCFC (hydrochlorofluorocarbon), and it is miscible with refrigerator oil most of the time under the working temperature of the oil separator in the refrigeration system. It is impossible to completely separate in the oil separator 20, and it is most convenient to explain the invention focus of the present invention by using it as a representative description. When the traditional oil separation method is used to measure the oil circulation rate of the R32 refrigeration compressor, some refrigerant is inevitably dissolved in the oil circuit measurement circuit, resulting in a relatively small flow rate in the refrigerant circuit and a large flow rate in the oil circulation circuit. After part of the refrigerant is too large, the measurement data of ...

Abstract

The invention belongs to the technical field of refrigeration, and particularly relates to a refrigerant compressor oil circulation rate measuring and testing device based on intermiscibility. The device comprises an oil separation assembly which is provided with an oil outlet end and a refrigerant outlet end, the refrigerant outlet end is at least communicated with a compressor air suction port end at least through a condenser, a liquid storage device and an evaporator to form a refrigerant loop, the oil outlet end is communicated with a compressor air suction oil return port to form an oil circulation loop, and flow meters are arranged on the oil circulation loop and the refrigerant loop. The device further comprises a refrigeration assembly, and liquid supply temperature of the refrigeration assembly is lower than the highest two-phase separation temperature of a refrigerant and refrigerator oil. The device improves work efficiency of a whole oil circulation system, meanwhile, values measured by the flow meters on the loops are more accurate, and finally precision of oil circulation flow rate measurement data of a refrigerant compressor is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of refrigeration, and in particular relates to a test device for measuring the circulation rate of refrigerant compressor oil based on compatibility. Background technique [0002] Refrigeration oil has the functions of lubrication, cooling, flushing, sealing, etc. It is an indispensable and important component of the refrigeration system. However, the mixing of refrigeration oil will also bring some negative effects to the refrigeration system, such as: changing the thermophysical properties of the refrigerant , Affect the heat transfer effect on the refrigerant side, etc. The circulation of refrigeration oil will affect the working performance of the refrigeration system, and the oil circulation rate flowing into the refrigeration cycle is also an important criterion for the evaluation of the lubrication and sealing performance of the compressor. [0003] The Chinese national standard GB / T5773-2004 stipula...
