Problems solved by technology

[0002] In related technologies, when the air-conditioning system needs to operate at low load for a long time, the operating frequency of the compressor is not low enough or the time allowed for the low-frequency operation of the compressor is too short, which will lead to frequent shutdown of the compressor at low load and fluctuations in the temperature of the air-conditioning room, resulting in compressor failure. Reduced reliability of operation and poor user comfort experience

Abstract

The present invention provides an operation control method, device, air conditioner and storage medium, wherein the operation control method of the air conditioner includes: determining the operating condition parameters to be collected according to the operating mode of the air conditioner; detecting Whether the system pressure difference meets the pressure difference requirement; if it is detected that the system pressure difference does not meet the pressure difference requirement, reconfigure the first set of control parameters related to the system pressure difference so that the compressor of the air conditioner can continue to run within the specified frequency range. By implementing this scheme, the compressor can reliably operate at low frequency until the system pressure difference meets the pressure difference requirement, and realize the adjustment of other control parameters for the compressor in the low-frequency operation state, so as to reduce the air conditioner's long-term The frequency at which the compressor is turned off and on when the load is low.
