毕业设计（论文）-大学学生宿舍楼飞的中央空调工程设计

摘 要

本工程为山东科技大学学生宿舍楼飞的中央空调工程，本工程的目的为根据所学基础理论和专业知识，结合本工程实际，设计出合适的空调系统，让生活在该宿舍楼的学生有良好舒适的空气环境，以便于他们全身心投入学习。 设计具体的方法为：首先进行建筑的冷热负荷计算，根据计算的冷热负荷确定工程的冷热源；然后进行建筑内部空调方式的比较和确定，确定空调方式以后便可以进行风系统和水系统的设计计算了，由计算结果就可以对所需设备进行比较和选型，并对相关细节进行处理；最后做出图纸和设计说明书以备参考使用。

经过认真严谨的计算和设计过程后，本设计采用的的空调系统经济合理，简单实用，达到了节能和舒适性的要求，并在建筑物特点和实际空调方式的基础上，使系统的功能性和和操作性得到提高。

Abstract

This works is for the central air conditioning engineering of Shandong University of Science and Technology students' dormitory building student.This project aims to according to the study of basic theory and professional knowledge, combined with the practical engineering, design a proper air-conditioning,Let the students live in good and comfortable air environment in the dormitory students, so that they devote themselves to their study.

The design methods are: First step is calculating building cooling and heating load, the hot and cold source for the project is determined based on the calculated cooling and heating load,and then compared the different air conditioning modes, so we can chose the suitable air conditioner, and the next step is designing and calculating of wind systems and water systems.The results can be compared for selection of the equipment, and relevant detail processing. Finally, make the design drawings and instructions for use and reference. Through the calculation and design process of serious posterior. The design of the air conditioning system is economical and reasonable, simple and practical, energy saving and comfort requirements, and based on the features of buildings and the actual air conditioning system, the function and operation of the system is to be improved.

Keywords：official building, central air conditioning, cooling water chiller fan coil units (F C Us)--fresh air system
