Abstract

The invention discloses an air conditioner and an oil return control method and device thereof. The oil return control method includes the steps of judging whether the operation condition of the air conditioner meets a preset condition which is used for triggering the air conditioner to start an oil return program, and controlling the air conditioner to start the oil return program under the condition that the operation condition of the air conditioner is judged to meet the preset condition so that oil return operation, at least comprising increasing of the operation frequency of a compressor of the air conditioner, can be executed. The technical problems that in the prior art, due to improper oil return of the compressor, the lubricating effect is poor, and abrasion of the compressor is high are solved.

Description

technical field [0001] The invention relates to the field of control, in particular to an air conditioner and an oil return control method and device thereof. Background technique [0002] At present, the oil return method of the air conditioner (for example, inverter air conditioner) is: when the detected frequency is continuously lower than a certain frequency and runs for a certain period of time (for example, 17 minutes), the oil return will start, and then the oil return time will be determined according to different frequencies and operating hours How long does it take to finally achieve the effect of lubricating the compressor. In low-frequency operation, it is necessary to return oil every 17 minutes, and the oil return is more frequent, and there is a certain irrationality in the formulation of oil return frequency and oil return time. However, the oil return at low frequency of the air conditioner will break the stable state of the environment, resulting in room t...
