The Design And Application Of Central Air-conditioning Simulation System

The central air-conditioning energy consumption which accounts for about60%in total energy consumption. With the shortage of resources, central air-conditioningenergy conservation research is an important thing. In common central air-conditioningresearch, there are two main methods: one is the project practice; the other one is theMATLAB simulation. The configuration software in combination with MATLAB, tomake up for deficiencies of existing methods, and construct a kind of simple andconvenient central air-conditioner simulation system.This article starts from the research status of air-conditioning system simulationtechnology, has been clear about the starting point and emphasis of centralair-conditioning simulation system design. In this paper, we introduce in detail thestructure and principle of central air-conditioning system, summarize the commonthree kinds of control method, and analyze their respective advantages anddisadvantages. In this article, we discard the disadvantages of complex codeimplementation in the existing central air-conditioning simulation system research,combine configuration software with MATLAB, use the entire GUI mode to constructthe picture, model and realize communication.We analyze the structure of cooling load of the shopping plaza, and partitionmodel control strategy is put forward. According to the traffic rules, shopping plaza isdivided into three control areas, and set up the models. According to the practicalextension module and corresponding variables, we formulate corresponding controlstrategy with the air-conditioning simulation system. Through the combined analysisof real time curve and history curve, we online verify and optimize the parametersrespectively.In the actual project, air-conditioning area is divided by partition model controlstrategy, and implemented corresponding control strategy. The new and old systemwork by alternating days. According to historical data, we know that the energy savingeffect of partition model control strategy is obvious.
