Water chilling unit control method, device and equipment and storage medium

Abstract

The invention relates to the technical field of water chilling units, in particular to a water chilling unit control method, device and equipment and a storage medium. Firstly, pre-selection actions of opening or closing are preset for the water chilling units, and the number of the water chilling units needing to execute the pre-selection actions is preset, that is, the preset number is determined. And if the preset number of water chilling units execute the preselection action, the limit cold load which can be borne by the preset number of water chilling units together is assumed. And meanwhile, predicting the prediction probability that the limit cold load corresponding to the preset number is matched with the future cold load, screening out a target number from the multiple preset numbers according to the prediction probability, and controlling the water chilling units of the target number to execute the pre-selection action. By predicting the probability that whether the limit cold load is matched with the future cold load or not, the number of the water chilling units is controlled to execute starting and stopping operation, so that the operation frequency of starting and stopping the water chilling units can be reduced, the running reliability of the water chilling units is improved, and energy is saved. 本发明涉及冷水机组技术领域，具体是涉及一种冷水机组控制方法、装置、设备及存储介质。本发明首先给冷水机组预设打开或关闭的预选动作，并预设有多少台冷水机组需要执行预选动作，也就是确定预设数量。并假设如果有预设数量的冷水机组执行预选动作，那么这些预设数量的冷水机组在一起所能承载的极限冷负荷。同时预测与预设数量所对应的极限冷负荷匹配未来冷负荷的预测概率，并根据预测概率，从多个预设数量中筛选出目标数量，并控制目标数量的冷水机组执行预选动作。本发明通过预测极限冷负荷是否匹配未来冷负荷的概率，以控制多少数量的冷水机组执行启闭操作，从而能够降低启闭冷水机的操作频率，进而提升冷水机组运行的可靠性并节省能源。
