Summary
as information technology and artificial intelligence technology in central air conditioning, and refrigeration technology popularization and promotion of industries, enabling better product performance and improvement. This article mainly introduces the main components of central air conditioner, classification and working principle and introduces features, structures, and types of control technology of central air conditioner; analysis of central air conditioning control, and control principle diagram. Central air conditioning is processed after a certain amount of air into the Interior in a certain manner, keep the indoor air temperature, relative humidity, cleanliness and speed of flow control within the appropriate range to meet the technology needs of comfort and a special technology. Central air conditioning system is made up of a host (or a refrigeration system or air supply system) through duct supply air or hot water-driven multiple Terminal, to achieve the purpose of indoor air conditioning air conditioning systems. This courses design in accordance with buildings automation central air conditioning fresh air unit control system design common of specification, and standard, detailed set out has load calculation, and air conditioning way of determines, and wind system design, and air conditioning water system design, and hot and cold source programme of determines, and refrigeration unit design, and air conditioning refrigeration construction figure design, content, and to out typical building air conditioning engineering of design instance and the main as courses design with, and has smart learning features of refrigeration air conditioning refrigeration design software.

摘要
随着信息技术、制冷技术以及人工智能技术等在中央空调行业的普及和推 广，产品性能也将得到有利得提高与改进。 本文主要介绍了中央空调的主要组成，分类以及工作原理；介绍了中央空调 的控制技术的特点、结构和类型；分析了中央空调的控制要求，并要求做出控制 原理图。 中央空调新风机组 DDC 控制就是把经过一定处理后的空气，以一定的方式 送入室内，使室内空气的温度、相对湿度、清洁度和流动速度等控制在适当的范 围内以满足生活舒适和生产工艺需要的一种专门技术。 中央空调系统是由一台主 机（或一套制冷系统或供风系统）通过风道送风或冷热水源带动多个未端的方式 来达到室内空气调节的目的的空调系统。 本课程设计按照楼宇自动化中央空调新 风机组控制系统设计常用的规范、 标准， 详细阐述了负荷计算、 空调方式的确定、 风系统设计、空调水系统设计、冷热源方案的确定、制冷机组设计、空调制冷施 工图设计等内容，并给出典型建筑空调工程的设计实例及主要作为课程设计用、 具有智能学习功能的制冷空调制冷设计软件。
