Research On Energy Saving Optimization Of Air Conditioning Equipment In Building Environment Building System Based On CPS

With the accelerated process of urbanization,the proportion of energy consumption in the total amount of energy consumption is increasing year by year,and the problem of building energy saving is becoming more and more prominent.In order to create a comfortable living environment,a large number of mechanical and electrical equipment are used in the building,in which the energy consumption of the air conditioning system accounts for 40%~50% of the energy consumption of the whole power system.Therefore,reducing the energy consumption of building air-conditioning system is an important part of reducing building energy consumption,and is also the basis for achieving energy optimization research of building environment building system.The current operating mode of the building air conditioning system is single,which can not meet the requirements of meeting the indoor comfort and reducing the energy consumption.The CPS system is applied to building environment of electromechanical equipment energy saving system,using CPS system: reliable sensing,real-time transmission,precise control,reliable service characteristics,real-time perception of the physical environment of buildings,and according to the actual needs of the air conditioning system of environmental regulation,in order to achieve on-demand supply,reduce energy consumption "the purpose of.The main work is as follows:(1)to study the theory of CPS system,the characteristics,functions and hierarchical structure of the system are analyzed.In view of the complex and changeable physical environment in the building,the building situational awareness model based on CPS is established.The model is divided into three levels,including collection layer,processing layer and service layer.The function and composition of each layer are explained in detail.Taking the flow density and temperature and humidity environment in the building area as an example,the corresponding detection methods and grade classification standards are put forward.(2)a study on energy saving control system of building environment,built the CPS building environment control system based on the optimization model of energy saving unit,on the basis of this,according to the actual needs of the environment(population density,temperature and humidity),using genetic algorithm,selection of parameters conform to the requirements of energy set as the initial population algorithm and after iterative calculation,get the optimal solution set,the regulation of the air conditioning system in accordance with the optimal solution concentration,to achieve the purpose of saving energy.(3)the Petri net theory is used to verify the rationality of the sequence of interlocking switches for all kinds of electrical equipment in air conditioning units and reduce unnecessary energy consumption.The crowd density and indoor temperature and humidity value are introduced to participate in the switching of the air conditioning system working mode.Through simulation,it is verified whether there is deadlock,whether the token is reachable,and whether it is reliable.It provides a theoretical basis for the energy saving control of the actual air conditioning system.
