【摘要】：经过了一个多世纪的发展,空调系统已经从只满足人类对空气温度的要求发展到能满足人类对空气温度、湿度、洁净度、风速等多方面的要求;在控制系统中应用自动控制理论,实现了空气调节设备对空气状态的准确调节;在建筑能耗方面通过合理的结构设计展现出了巨大的节能潜力。本文基于济南某公园管理处办公楼设计项目,从实际出发,设计一套新风机组空调控制系统,实现建筑内空气温湿度调节和空气环境改善,并通过合适的结构设计,在上述基础之上尽可能降低空调系统的能耗,体现绿色环保的设计理念。论文首先概述了本课题做空调系统的目的和意义,介绍了典型空调系统的组成与分类和国内外的研究动态;其次阐述了空气调节的热力学原理、空调系统控制任务和应用的控制原理;然后对空调系统的新风机组进行了结构设计,采用多级温湿度处理,并对应用的空气处理设备进行了建模分析,总结其控制特点,得出了控制系统的传递函数,针对系统中温湿度在控制过程中的耦合情况应用前馈补偿法设计了前馈补偿器,解除了其中的耦合,实现了温湿度的独立控制;最后根据整体的设计方案完成了电气设计、程序设计、上位机组态设计,并在现场通过调试运行,使空调系统在空气的过滤、温湿度处理、室内环境调节等方面实现了预期效果,满足了设计要求。
[Abstract]:After more than a century of development, air conditioning system has been developed from only to meet the air temperature requirements to meet the air temperature, humidity, cleanliness, wind speed and many other requirements; The automatic control theory is applied in the control system to realize the accurate regulation of the air state by the air conditioning equipment, and the energy consumption of the building has shown great energy saving potential through the reasonable structural design. Based on the design project of an office building of a park management office in Jinan, a set of air conditioning control system of fresh air unit is designed to realize the air temperature and humidity adjustment and air environment improvement in the building, and the proper structure design is adopted. On the basis of the above, the energy consumption of air conditioning system is reduced as much as possible, and the design concept of green environmental protection is embodied. Firstly, this paper summarizes the purpose and significance of this subject, introduces the composition and classification of typical air conditioning system and the research trends at home and abroad, and then expounds the thermodynamic principle of air conditioning. The control task of air conditioning system and the control principle of its application are analyzed. Then, the structure of the fresh air unit is designed, and the multi-stage temperature and humidity treatment is adopted. The model of the air treatment equipment is analyzed, and the control characteristics are summarized. The transfer function of the control system is obtained, and the feedforward compensator is designed for the coupling of temperature and humidity in the control process by the feedforward compensation method. The coupling of the feedforward compensator is uncoupled and the independent control of temperature and humidity is realized. Finally, according to the overall design scheme, the electrical design, the program design, the configuration design of the upper computer are completed, and the air conditioning system is filtered in the air, and the temperature and humidity are treated by debugging and running on the spot. The expected effect of indoor environment regulation has been realized and the design requirements have been met.
