Cooling load prediction method and system used for electronic factory

The invention relates to a cold load prediction method and system used for an electronic factory. A corresponding relation table between the wet bulb temperature and the total cold supply amount in different seasonal modes and different time periods is firstly established, then, according to the seasonal mode and time period of a prediction moment and the wet bulb temperature of the prediction moment, the total cold supply amount at the prediction moment is obtained through the corresponding relation table, the cooling load is predicted according to the total cold supply amount, then the cooling load needing to be supplied can be accurately predicted, on-demand supply of the cooling load is achieved, and energy consumption of a central air conditioning system is reduced. 本发明涉及一种用于电子工厂的冷负荷预测方法及系统，先建立不同季节模式不同时间段下湿球温度与供给总冷量之间的对应关系表，然后根据预测时刻所处的季节模式和时间段以及预测时刻的湿球温度，利用对应关系表得到预测时刻的供给总冷量，并根据供给总冷量对冷负荷进行预测，进而能够对需要供给的冷负荷进行准确预测，实现冷负荷的按需供给，降低中央空调系统的能耗。
