暖通设计概述

1、绪论?设计目的空调课程设计是暖通空调课程的重要教学环节之一，通过这一环节达到 了解空调设计的内容、程序和基本原则，学习设计计算的基本步骤和方法， 巩固 暖通空调课程的理论知识，培养独立工作能力和解决实际工程问题的能力。同时，利用与之相关的软件，增强应用与创造能力。如用于辅助设计的CAD用于编写文档的WORD用于数据统计的EXCEL都是帮助我们高效工作的工具， 故此，此次课程设计不仅是对空调工程的专业知识的应用，也是对当代的我 们应用各种计算机软件的一个考验。?设计任务整个设计要求完成恒温车间（一层）的空调设计。应将设计结果整理成设计 计算说明书，其中包括：原始资料、设计方案、计算公式、数据来源

2、、设备类型、 主要设备材料表。设计成果还应能用工程图纸表达出来，必须提供空调平、剖面 图、系统图及机房详图。指导老师：马荣生 丁兴凤目录 TOC o 1-5 h z HYPERLINK l bookmark4 o Current Document 一、原始资料 1 HYPERLINK l bookmark6 o Current Document （一）建筑及结构 1 HYPERLINK l bookmark8 o Current Document （二）气象资料 1 HYPERLINK l bookmark10 o Current Document （三）工艺资料 1 HYPERLINK l
