Abstract

The invention provides operation control method and device, an air conditioner and a readable storage medium. The operation control method comprises the steps of respectively acquiring air inlet temperature and air outlet temperature of an air conditioner indoor unit, and surface temperature of a heat exchanger; determining a current temperature characteristic proportion according to the air inlettemperature, the surface temperature of the heat exchanger and the air outlet temperature, wherein the current temperature characteristic proportion corresponds to current heat exchange efficiency ofthe heat exchanger; determining whether adjusting parameters of a fan are generated or not according to a relation between the current temperature characteristic proportion and a preset target temperature characteristic proportion, wherein the target temperature characteristic proportion corresponds to target heat exchange efficiency adaptive to a target air volume; and if generating the adjusting parameters, adjusting the rotary speed of the fan according to the adjusting parameters. According to the technical scheme provided by the invention, a calculation model in the control process is simplified, so that the convenience in implementation is realized; and in addition, the fan speed is adjusted based on the acquired temperature values, so that high reliability is realized.

Description

technical field [0001] The present invention relates to the field of air conditioners, in particular to an operation control method, an operation control device, an air conditioner and a computer-readable storage medium. Background technique [0002] Since the air volume is a key factor affecting the cooling or heating effect of the air conditioner system, if the air volume cannot be kept constant, it will directly affect the cooling or heating effect. In related technologies, the indoor unit of the air conditioner uses sensors to monitor the fan during operation According to the characteristic curve of the fan, the current air volume and static pressure are obtained, and finally the motor speed is reversely adjusted according to the required static pressure and air volume to achieve the control output of constant air volume. The current defects of this control method include: [0003] (1) The control process is more complicated; [0004] (2) Since the control accuracy of t...
