Air conditioning unit and method for detecting oil level of compressor thereof

Abstract

The invention aims to solve the problem of oil level judgment for a high pressure chamber compressor and provides an air conditioning unit and a method for detecting the oil level of a compressor thereof. The air conditioning unit is provided with a compressor part with an oil level detector, which can accurately judge whether the oil level is lower than the normal work oil level in the operation process of the compressor, provides reliable reference for the system to perform oil equalization operation and ensures safe and stable operation of the high pressure chamber compressor. The compressor part of the air conditioning unit also has the oil level detector which comprises an oil storage tank, an oil equalization tube connected to the normal oil level position of the compressor, and a first check valve and a first capillary tube which are arranged on the oil equalization tube; the two ends of the oil equalization tube are respectively connected with a casing and the oil storage tank of the compressor; one end of the first capillary tube close to the oil storage tank is provided with a first thermal bulb; the exhaust port of the compressor is provided with a second thermal bulb; and the first thermal bulb and the second thermal bulb are electrically connected with a control component.

Description

Air-conditioning device and method for detecting oil level of its compressor technical field The invention belongs to the technical field of air conditioners, in particular to the technical fields of multiple machines and compressors. Background technique In the field of air-conditioning technology, in a multi-line system in which multiple compressors operate in parallel, the oil balance between compressors is a key technical issue that affects system stability. For low-pressure chamber compressors, oil equalization between compressors can be achieved by setting oil-air balance pipes. As for the high-pressure chamber compressor, since the oil chamber is at the high-pressure end, the oil balance pipe cannot be directly used for oil equalization. When the oil level is unbalanced, the refrigeration oil must be evenly distributed through a specific oil equalization process. Accurately judging the oil level of the compressor is a necessary condition for the oil equalization pr...
