Problems solved by technology

[0004] However, in the current technology, once a control device participating in the cooperative control fails, the control strategy will be affected and no longer applicable, resulting in the control parameters of other normally working control devices being no longer suitable, and the reliability is low.

Abstract

The invention discloses a method and a device for controlling an air conditioner, and an air conditioning system. The method comprises the following steps: cyclically executing a technical scheme of return air temperature control until the current return air temperature detection value is equal to a return air temperature set value, and cyclically executing a technical scheme of supply air temperature control until the current supply air temperature detection value is equal to a supply air temperature set value, wherein the return air temperature control and the supply air temperature control are corresponding to an independent control component and an independent control logic respectively, are mutually independent from each other and have no mutual interference, and are also mutually independent from control for other components of the air conditioner and have no mutual interference, that is, the return air temperature control and the supply air temperature control are not influenced in the case that the other components are failed. Hence, the technical scheme provided by the invention is capable of improving the reliability of the return air temperature control and the supply air temperature control relative to the prior art.

Description

technical field [0001] The present invention relates to the technical field of control, in particular to an air-conditioning control method, device and an air-conditioning system. Background technique [0002] Air-conditioning has been widely used by people with its good effects such as refrigeration. The return air temperature control of the air conditioner and the supply air temperature control of the air conditioner play an important role in the good operation of the air conditioner. [0003] The current technology is an air-conditioning control technology that simultaneously controls the return air temperature and the supply air temperature. A fixed finite control strategy has been formulated for different working conditions. After collecting various temperature information, one of the control strategies is selected to control multiple control devices. Unified control, through the synergistic effect of multiple control devices, the purpose of controlling the return air ...
