The invention relates to the technical field of air conditioner control, particularly provides a control method and system of an air conditioner compressor, and aims to solve the problems that an existing compressor is single in oil return process control mode and poor in oil return effect. In order to achieve the purpose, the control method of the air conditioner compressor comprises the steps that after it is detected that the compressor is started, a control result of oil return control of the compressor last time is obtained; oil return control is conducted on the compressor in an oil return control mode matched with the control result; and after oil return control, the next oil return control is selectively conducted on the compressor according to the actual operation state of an air conditioner. The problems that the previous oil return control process cannot be executed or is not completed due to abnormal conditions in the previous oil return control process, the oil return of the compressor is incomplete, the oil return effect is poor, and the performance of the compressor is influenced can be effectively avoided; and meanwhile, the oil return effect of the compressor in the stable operation stage can be ensured.
Description
technical field [0001] The invention relates to the technical field of air-conditioning control, and specifically provides a control method and system for an air-conditioning compressor. Background technique [0002] The air conditioner compressor plays the role of compressing and driving the refrigerant in the air conditioner refrigerant circuit, so the compressor is very important in the operation of the air conditioner. When the compressor is running, the compressor often lacks oil. [0003] In the prior art, for the lack of oil in the compressor, the main control method is automatic oil return, that is, the compressor automatically enters the oil return mode after running for a period of time. Although this control method plays the role of oil return to a certain extent, the control method is relatively simple. If there is an abnormal situation, such as compressor failure or compressor shutdown, the oil return cannot be performed normally, resulting in incomplete oil re...
