2.9KW中型卡车空调制冷系统匹配设计

摘要：本文主要内容为汽车空调系统匹配设计。首先介绍了汽车空调的发展过程及其前景，并针对汽车空调的特点做了进一步详细的介绍。对其参数及制冷剂的使用也有简单概述。对设计题目2.9KW中型卡车空调制冷系统匹配来进行了详细的设计计算。进行卡车的冷负荷计算，确定其所需冷量，并据此确定制冷剂及卡车使用的压缩机。主要部分为空调系统匹配冷凝器与蒸发器，详细的阐述了冷凝器与蒸发器的设计计算，计算了传热系数和空气阻力损失并对其进行了校核，对整体结构也进行了可行的设计，并附上了尺寸图。蒸发器采用板翅式，是较为高效的换热器。计算了析湿系数与湿工况下空气侧表面传热系数，通过对传热系数和传热面积的计算，确定了尺寸，对其结构进行了设计，并附有具体尺寸图。
