Abstract

The invention discloses an oil return control method, device and appliance and a storage medium, and belongs to the technical field of air conditioners. The method comprises the steps that compressors in the oil shortage state in an air conditioner system are determined; when the number of the compressors in the oil shortage state is smaller than the total number of compressors in the air conditioner system, the compressors in the oil shortage state are increased to a target frequency from a first operation frequency so that the compressors in the oil shortage state can be subjected to oil return; the current second operation frequency of compressors which are not in the oil shortage state in the air conditioner system is acquired; the current load of the air conditioner system is determined according to the second operation frequency and the target frequency; and the compressors which are not in the oil shortage state are controlled to operate according to the current load. By controlling the compressors which are not in the oil shortage state to operate according to the current load of the air conditioner system while performing oil return on the compressors which are in the oil shortage state, it is guaranteed that the load of the air conditioner system does not fluctuate during oil return of the compressors, and therefore the comfort of a user is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioner control, in particular to an oil return control method, device, equipment and storage medium. Background technique [0002] The compressor is the core module of the air-conditioning system. The compressor needs lubricating oil during operation, otherwise the compressor will be damaged due to overheating or wear. In order to ensure the safe and reliable operation of the air-conditioning system, the compressor must maintain a safe oil level to keep the compressor The amount of oil is higher than the minimum amount of oil required by the compressor to ensure safe and reliable operation of the compressor. The traditional modular machine has multiple outdoor units and is independent of each other, and the oil return method is to switch the currently running compressor to the oil return frequency at the same time for oil return, which will cause large fluctuations in the system load in a short p...
