摘要：本次课题的目的是让人们在夏季中乘坐公交车可以有一个更舒适的环境。本文对空调的主要部件及其作用进行了介绍。本次课题主要在于空调系统的设计，在本次设计中主要有四大难点：空调系统中各种参数的查寻、对空调调系统的各种负荷进行计算、对空调主机中的冷凝器、蒸发器的设计、对空调系统的风系统进行计算。42492

由于本次设计是对公交车的空调系统设计。所以，此次设计的负荷计算中并不包括热负荷。在进行空调系统的风系统进行计算时运用了鸿业暖通软件来运算。

本次设计通过运用鸿业暖通，CAD等软件完成了对空调系统的各个主要部件的设计。在老师的帮助下完成了本次设计。

Air Conditioning System Design For Shanghai Bus

Abstract:The purpose of this topic is to allow people to take the bus in the summer can have a more comfortable environment. In this paper, the main parts of the air conditioning and its role were introduced. This topic mainly depends on the design of air conditioning system. There are four major difficulties in this design:various parameters of air conditioning system in the search.the air-conditioning system for a variety of load calculation

 The design of condenser and evaporator in air conditioning system .the air conditioning system design of the wind system.

Because this design is the air conditioning system design of the bus. Therefore, the design of the load calculation does not include thermal load.In the wind of air conditioning system is calculated by Hongye HVAC software operations. This design through the use of Hongye HVAC CAD software, completed the design of each of the major components of the air conditioning system with the help of the teacher completed the design.

Keywords :Parameters, load, condenser, evaporator
