The invention relates to the technical field of air conditioner systems, and discloses an oil returning detection device, a compressor and an oil returning control method. The oil returning detection device comprises an oil returning fixing base, a sliding rod arranged on the oil returning fixing base and an oil returning floating component arranged on the peripheral wall of the sliding rod in a sleeving manner; a first limiting component is arranged on the portion, close to the upper end face of the oil returning fixing base, of the sliding rod, and a second limiting component is arranged on the top of the sliding rod; the oil returning floating component can do reciprocating motion between the first limiting component and the second limiting component in the axial direction of the sliding rod along with the height of the oil level in the compressor. The oil returning detection device has the beneficial effects that oil can be effectively returned in time, and wear caused by oil starvation of the compressor is avoided.
Description
technical field [0001] The invention relates to the technical field of air conditioning systems, in particular to an oil return detection device, a compressor and an oil return control method. Background technique [0002] At present, most of the oil return of the air conditioning unit is carried out after the detection of its running to a fixed time. For the air conditioning system with a small oil discharge, the oil return is carried out within a fixed time, which will make the working performance of the whole machine And the power of the whole machine fluctuates greatly. For the air-conditioning system with a large amount of oil discharge, the oil is returned within a fixed time, which will cause the compressor to wear and tear and reduce the service life of the compressor due to the untimely oil return of the whole machine. [0003] For this reason, in view of the above-mentioned defects, the designer of the present invention researches and designs an oil return detecti...
