An air-conditioning system linkage energy-saving control system and method

Abstract

The invention discloses an air-conditioning system linkage energy-saving control system. The wind-water linkage intelligent controller automatically adjusts the wind-water linkage energy-saving control device according to the working condition parameters, and the cooling water pump and the chilled water pump intelligent controller automatically adjust the cooling water pump and the chilled water pump respectively according to the working condition parameters. The operating frequency and number of the cooling tower and the cooling host intelligent controller automatically adjust the number of cooling tower fans and refrigeration hosts according to the working conditions. The proportional regulating valve and the energy-saving controller of the blower adjust the opening of the air valve at the end of the air supply branch pipe, the proportional regulating valve of chilled water and the operating frequency of the blower respectively. The invention also discloses an air-conditioning system linkage energy-saving control method. The system of the present invention automatically matches the parameters of the energy-saving working conditions of the current system to adjust the electrical equipment and controllers in the system, so that the air-conditioning system operates at the best efficiency and achieves the purpose of reducing the total energy consumption of the system.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning energy saving, in particular to an air-conditioning system linkage energy-saving control system and method. Background technique [0002] With the development of intelligent building technology, automation systems such as central air-conditioning computer control, constant pressure water supply, and intelligent lighting create a comfortable working and living environment for buildings, but also bring huge energy consumption demands. Among them, the central air-conditioning system is an important part of the building system, which accounts for a large proportion of the energy consumption of the entire building system. According to statistics, the energy consumption of the construction industry accounts for 30% of the country's total energy consumption, and the electricity consumed by the air-conditioning system It can account for 60% to 70% of the energy consumption of the entire b...
