Abstract

The invention discloses an on-off optimization control method and device of a central air-conditioning system. The method comprises the following steps that: S1. a controller acquires the operating signal of each equipment of the central air-conditioning system in real time; S2. on-off commands of a user are received; S3. the controller automatically accumulates the operating time of each equipment of the central air-conditioning system according to the operating signals to respectively compare the equipment with the shortest operating time and the equipment with the longest operating time inthe same equipment of each equipment in the central air-conditioning system; and S4. the controller sequentially starts the equipment with the shortest operating time in the same equipment or closes the equipment with the longest operating time in the same equipment according to the on-off sequence and operating time of each equipment of the central air-conditioning system, thereby outputting starting or closing control signals. By applying the technical scheme of the invention, the operation stability of the system and the convenience of maintenance equipment are improved, and the energy consumption of the system is reduced.

Description

technical field [0001] The invention relates to the field of starting and stopping of a central air-conditioning system, in particular to a method and device for optimally controlling the starting and stopping of a central air-conditioning system. Background technique [0002] At present, building central air-conditioning systems are generally managed and operated by building managers, and the start-stop control methods are as follows: [0003] When starting each equipment in the central air-conditioning system, the starting time is determined according to the outdoor temperature and humidity and the working time. Generally, the controller will turn on the electric butterfly valve of the refrigerator, turn on the cooling tower, turn on the cooling water pump, turn on the cold water pump, and start Start up the refrigerators in sequence; when the equipment in the central air-conditioning system is turned off, the shutdown time is determined according to the outdoor temperatur...
