Abstract

The invention provides cooling load prediction control method and device, applied to a dynamic ice storage air conditioning control system. The cooling load prediction control method comprises the following steps: dividing one day into a plurality of first preset time segments, dividing each first preset time segment into a plurality of second preset time segments, and collecting and calculating a water flow rate and a temperature difference between supply water and return water in a freezing water pipeline in each second preset time segment; calculating an actual cooling load value in each second preset time segment according to the water flow rate and the temperature difference between supply water and return water in the corresponding second preset time segment; and solving an average of the actual cooling load values with a preset number as a predicted cooling load value in the following second preset time segment. With the design, the demand for cooling capacity in a next day can be more accurately predicted, and control is optimized.

Description

technical field [0001] The invention relates to the technical field of control, in particular to a method and device for predictive control of cooling loads. Background technique [0002] The existing dynamic ice storage control system perceives the change of the supply load according to the change of the return water temperature at the end, and the response is slow, so it cannot timely feedback the real-time load at the end. Unable to respond to the changing demand of the terminal load in time, resulting in a large amount of overshoot and hysteresis, resulting in a large amount of waste of cooling capacity. In addition, it is impossible to accurately predict the cooling demand for the next day, resulting in insufficient ice storage or a large excess. Contents of the invention [0003] In view of this, embodiments of the present invention provide a cooling load forecasting control method and device, which can solve the above problems. [0004] In order to achieve the abo...
