Abstract

The invention discloses an air conditioning unit operation optimization method and system. The method comprises the following steps: S1, initial value setting: initial values are set, and the initial values comprise an optimization period, a data acquisition period, an operation parameter constraint condition and a genetic algorithm initial value; S2, data collection, wherein operation parameters of the air conditioning unit are collected and stored; S3, data preprocessing: the operation parameters acquired in the step S2 is processed to obtain effective operation parameters; and S4, energy-saving optimization: the operation parameters of the air conditioning unit in the next optimization period is optimized by utilizing the effective operation parameters obtained in the step S3 to obtain optimized operation parameters. According to the method, the optimization process is simplified, the simplified process is verified, and a good energy-saving effect is achieved.

Description

technical field [0001] The invention belongs to the field of air-conditioning unit control, and in particular relates to an operation optimization method and system for an air-conditioning unit. Background technique [0002] The air conditioning unit is the main terminal refrigeration equipment of the central air conditioning system. Most of the AHUs in the central air-conditioning system of existing buildings operate in a constant air volume mode. Because the chilled water temperature of the refrigeration main engine is relatively constant, that is, the cooling capacity output is controlled only by adjusting the chilled water flow rate. Compared with the variable air volume mode, the control method is relatively simple. The applicability of the change of working conditions is poor, and it is easy to cause the system to operate in low efficiency under partial load conditions. The conventional variable air volume operation mode usually sets the air supply temperature to a fi...
