Abstract

The invention discloses a building cooling load prediction method and a device of an air conditioning refrigerator. The method comprises the steps of: acquiring meteorological parameters in multiple positions out of a building, and calculating heat out of the building; counting heat parameters in the building, and calculating heat in the building; building a building physical model according to the heat out of the building and the heat in the building; and acquiring operation data of an air conditioning refrigerator system in a preset time, training the building physical model according to a genetic algorithm, building an ash bin model, and predicting a building cooling load. The method has the beneficial effects of fastness, high accuracy, organic integration of prediction and feedback optimal control, capability of realizing precise and accurate control of a central air conditioning system and realization of effective energy saving effect.

Description

technical field [0001] The invention relates to the technical field of air-conditioning control, and more specifically, to a method and device for predicting building cooling load of an air-conditioning refrigerator. Background technique [0002] The energy consumption of central air-conditioning accounts for 65% of the total energy consumption of buildings, of which the energy consumption of refrigeration stations accounts for about 70% of the energy consumption of air-conditioning systems; in the cooling period in southern China, the energy efficiency management and control of central air-conditioning systems must be based on building cooling load forecasting , in order to achieve effective management and significant energy saving. Only when the building cooling load forecast is more accurate, can the scheduling and operation of the central air-conditioning system based on the building forecast load be based on evidence, so as to realize the efficient operation and energy ...
