Abstract

The invention relates to the technical field of air conditioners and provides a method and a device for forecasting air-conditioning load and an air-conditioner. The method comprises steps of acquiring the parameter amount affecting the air-conditioning system load; inputting parameters to an air-conditioning load forecasting neuronic network model which is trained in advance; and acquiring the prediction value of the air-conditioning load. The air-conditioning hourly load of the air-conditioning system can be predicted accurately, the refrigerating capacity changes with the air-conditioning load, the energy is not wasted, the operation and the adjustment of a water cooling unit has a basis, and the water cooling unit can operate at the best efficiency state.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner load forecasting method, device and air conditioner. Background technique [0002] The operation mode of the traditional air-conditioning system is mainly to adjust the cooling capacity of the air-handling unit by directly comparing the deviation between the room temperature and the set temperature. In the process of air-conditioning system adjustment, only the air-conditioning load is included in the closed loop as the disturbance quantity. In the control loop, the dynamic change of the air conditioning load is not considered. Due to the lack of consideration of the dynamic change of the air-conditioning load, it often leads to the situation that the cooling capacity is inconsistent with the change of the air-conditioning load. For example, the cooling capacity may not meet the cooling capacity required by the air-conditioning load, or the...
