Abstract

The invention discloses an air conditioner as well as a detection method and device for the compressor oil level of the air conditioner. The method comprises the following steps: a first temperature and a second temperature are acquired, wherein the first temperature is the detected temperature of the upper end of a warning line of a compressor, and the second temperature is the detected temperature of the lower end of the warning line of the compressor; the difference of the first temperature and the second temperature is calculated; the difference and a preset temperature are compared; oil return of the compressor is controlled when the difference is larger than the preset temperature. The air conditioner as well as the detection method and device for the compressor oil level of the air conditioner solve the technical problem of lower detection accuracy of the compressor oil level in the prior art.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner and a method and device for detecting the oil level of a compressor thereof. Background technique [0002] At present, the air conditioner system judges whether it enters the oil return mainly by detecting the running time of the air conditioner in the low frequency band to determine whether the compressor is short of oil. However, in actual operation, there are certain limitations in judging whether the compressor is short of oil based on the running time. It may happen that the compressor has a lot of oil, but the air conditioner enters the oil return, which greatly reduces the comfort and wastes energy; or The compressor is short of oil and the air conditioner fails to return the oil in time, which greatly reduces the reliability of the compressor. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0...
