Abstract

The invention relates to a capability output control method of an air conditioner indoor machine, terminal equipment and a computer readable medium. The method comprises the steps of acquiring a capacity parameter of the indoor machine, wherein the capacity parameter is set according to the capacity of the indoor machine; acquiring a temperature difference correction coefficient, corresponding toa current moment, of the indoor machine, wherein the temperature difference correction coefficient is determined according to an environmental temperature where the indoor machine is located and a working target temperature; calculating a capability demand output value of the indoor machine at the current moment according to the capacity parameter and the temperature difference correction coefficient; and performing capability output control on the indoor machine in real time according to the capability demand output value. Feedforward capability output control is performed on the air conditioner indoor machine, the actual capability demand is estimated in real time during the starting and running process of the indoor machine, so that the capability output control of the air conditioner system is more accurate and stable.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a method and device for controlling the capacity output of an air conditioner indoor unit and a computer-readable storage medium. Background technique [0002] At present, the target evaporation temperature or condensation temperature is mostly used to adjust the cooling and heating capacity output control of the air conditioning system, which belongs to the extensive capacity output control. When the indoor unit is turned on, the air conditioning system does not know how much capacity output the indoor unit needs. It can only perform extensive capacity output control through the system preset target evaporation temperature or condensing temperature. After the system is running, the indoor unit will be tested again. The tube temperature and temperature difference, the correction capability output correction control. This simple feedback output control is lik...
