Linkage energy-saving control system and method for air conditioning system

Abstract

The invention discloses a linkage energy-saving control system for an air conditioning system. An air and water linkage intelligent controller automatically adjusts an air and water linkage energy-saving control device according to working condition parameters. A cooling water pump and chilled water pump intelligent controller automatically adjusts the operation frequencies and the numbers of cooling water pumps and chilled water pumps according to the working condition parameters. A cooling tower and refrigerating host intelligent controller automatically adjusts the number of operated cooling tower draught fans and operated refrigerating hosts according to the working condition parameters. An air conditioner tail-end intelligent controller adjusts the opening degrees of air supply branch pipe tail-end air valves and chilled water proportion regulating valves and the operation frequencies of air feeders respectively through an air supply branch pipe tail-end air valve, chilled water proportion regulating valve and air feeder energy-saving controller according to the working condition parameters. The invention further discloses a linkage energy-saving control method for the air conditioning system. The linkage energy-saving control system is automatically matched with the energy-saving working condition parameters according with the current system, electric equipment and the controllers in the air conditioning system are adjusted, the air conditioning system runs at the best efficiency, and the purpose of reducing the total energy consumption of the system is achieved.

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...
