摘要
采用谐波反应法对重庆长安汽车公司生产的“长安牌”SC10 11A微型载货汽车空调冷负荷进行了分析计算。分析表明 ,谐波反应法比传统的稳态计算法更能准确地体现出汽车空调负荷动态变化的特性。计算结果表明 ,该型汽车空调冷负荷最大出现在下午 14 :0 0 ,其值为 30 98W。在整个空调负荷中 ,车窗得热量和维护结构得热量最大 ,占到总得热量的 5 0 0 %。漏风得热量占到 2 7.3% ,表明需进一步改进车体的密封性能。重庆长安汽车公司根据该结果对该车汽车空调系统进行了优化设计 ,实车通过环境模拟测试 。
This paper adopts harmonic reaction method to calculate the cooling load of the air conditioning system of the NO.1011A loaded miniature cars in Chongqing Chang'an Automobile Company .The study indicates that harmonic reaction method is more exact than traditional steady method to show the dynamic characteristic of cooling load. The maximum cooling load appears on 2:00 pm, it's 3 098 W. Among the whole cooling load,heat load through windows and heat load through components are the biggest,they occupy 50% of the whole amount. Heat load of air leaks occupies 27.3%,which shows that it is necessary to improve the seal of cars. Chongqing Chang'an Automobile Company develops optimize design for the air condition system with this result, which reaches a perfect climate effect.
