KW中型卡车空调制冷系统匹配设计

精品文档---下载后可任意编辑摘要：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进展过程及其前景，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。蒸发器采纳板翅式，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。关键词：汽车空调，匹配设计，蒸发器，冷凝器。Abstract:Main content designs the main body of a book for automobile air-conditioning system mates. The process having introduced development of automobile air-conditioning first and their prospect, and specifically for automobile air-conditioning characteristic has made further detailed introduction. To whose parameter and the refrigerant, sigmatism can't have a summary simple. The detailed design coming to have been in progress to the refrigerating system designing medium-sized examination questions 2.9 KW trucks air-conditioning matching secretly schemes against The load carrying out the truck cooling down secretly schemes against , ascertains compression engine needed cold amounts , joined accordingly to ascertain the refrigerant and truck usage by whose. Major component condenser and evaporation implement mating for air-conditioning system, the design having set forth a condenser and having evaporated an implement detailedly secretly schemes against, core having calculated heat passage modulus and air drag loss and having carried out school on the person, the dimension having also carried out feasible design, and enclosing herewith on entirety ...
