The invention discloses an air conditioning system water chilling unit group control method and device, electronic equipment and a storage medium, and the method comprises the steps that current operation parameters of water chilling units in an air conditioning system are obtained; comparing the current header pipe water supply temperature of the water chilling unit with a water supply temperature set value, and generating a regulation and control strategy of the water chilling unit according to a comparison result and the current operation parameters; and calculating the operation efficiency of the water chilling unit under the regulation and control strategy by using a pre-constructed water chilling unit ICOP-DCOP model, and matching a target regulation and control value of the water chilling unit according to the operation efficiency. Therefore, the running number and frequency of the water chilling units are automatically adjusted and optimized according to actual cooling requirements under different running working conditions in the cooling season, so that the efficient running of the water chilling units is maintained for a long time, and the running energy consumption of the system is reduced; the problem that an existing regulation and control strategy cannot carry out operation regulation and control based on evaluation and prediction of actual operation efficiency is solved.
Description
technical field [0001] The present application relates to the technical field of automatic control of an air-conditioning system, and in particular to a group control method, device, electronic equipment and storage medium of chillers in an air-conditioning system. Background technique [0002] While providing a healthy and comfortable indoor environment for the building, the air-conditioning system also consumes a large amount of energy. According to statistics, the energy consumption of the air-conditioning system accounts for about 30% to 50% of the total energy consumption of public buildings. Therefore, the energy-saving control of the air-conditioning system is of great significance to the energy-saving of public buildings and the energy-saving work of the entire building field. The energy consumption of the chiller is an important part of the energy consumption of the air conditioning system, accounting for 50%-80% of the energy consumption, and its operating efficien...
