Description

technical field [0001] The invention relates to the technical field of central air-conditioning control, in particular to a central air-conditioning continuous optimization system and method. Background technique [0002] In recent years, with the continuous increase of the proportion of building energy consumption in the total energy consumption, people pay more and more attention to building energy conservation, and central air conditioning accounts for the majority of building energy consumption. Therefore, how to reduce the energy consumption of central air conditioning , and the ability to optimize the system during the operation period of the central air conditioner is one of the key research technologies of the central air conditioner. However, the existing systems for optimizing the central air conditioner have the following problems in the actual use process: [0003] 1. At present, for the optimization of the central air-conditioning system, the RC air-conditioning...

[0003] 1. At present, for the optimization of the central air-conditioning system, the RC air-conditioning optimization method is mostly used in foreign countries, that is, to optimize the construction of the existing air-conditioning system in the building. However, the RC air-conditioning optimization method only focuses on the optimization during the construction period. The continuous improvement and energy-saving optimization of the central air-conditioning system cannot be realized during the equipment operation period

[0004] 2. The traditional domestic air-conditioning tuning method is often to adjust the water and air volume by controlling the opening of the valve or damper for the water and air system of the central air-conditioning system, and some central air-conditioning systems use frequency converters to control the pump or its speed In these control methods, the control system is only partially modified, which has great limitations, single control mode, and failure to consider the influence of air humidity and wind pressure on the system. Therefore, traditional tuning In the method, the refined management of system operation is not achieved, so that the operation mode of the equipment cannot be fully optimized, and it is difficult to realize the maximum saving of electric energy
