The invention relates to a control device for an air-conditioning cooling water system and a data processing method of a main control module of the control device. The control device comprises a network controller, a temperature and humidity sensor and the main control module connected with the network controller and the temperature and humidity sensor. In the control device, operating state data of a water chilling unit are sent to the main control module by the network controller, and outdoor temperature and humidity data are acquired by the temperature and humidity sensor, and are sent to the main control module; corresponding actual operating frequencies are sent to the main control module by frequency converters of a cooling tower fan and a cooling water circulating pump; and the optimized result that the total energy consumption of the air-conditioning cooling water system is lowest is obtained through calculation by the main control module according to received data, and the operation of the cooling tower fan and the cooling water circulating pump is controlled according to the optimized result, so that the air-conditioning cooling water system operates in the optimal state, and the energy consumption of the air-conditioning cooling water system is greatly reduced.
Description
technical field [0001] The invention relates to the field of optimization control, in particular to a control device for an air-conditioning cooling water system and a data processing method for a main control module thereof. Background technique [0002] The cooling water system of the central air conditioner mainly includes chillers, cooling towers, cooling water circulation pumps and pipelines. Among them, the chiller is responsible for preparing low-temperature chilled water supplied to the end of the user, and generates condensation heat; the cooling tower uses circulating cooling water as the coolant, uses the flowing contact between water and air to exchange heat and cold to generate steam, and uses evaporation to dissipate heat and convective heat transfer The condensation heat generated by the chiller is discharged into the atmosphere to reduce the temperature of the cooling water by the principle of heat transfer and radiation; the cooling water circulation pump is...
