摘要
在轻量化改进大型客车空调设计的过程中,壳体的制作材料使用5052-H32铝板代替原有的3003-H24铝板,并将汽车空调的壳体由原设计的单一厚度结构改为不同部位采用不同厚度铝板结构。设计改进后的天然气大型客车空调的长度缩短了8.8%,质量减少了18.6%。经焓差试验室的验证,轻量化设计改进对大型客车空调制冷性能的影响在GB/T21361—2008允许的测量误差范围内。
In the design of light-weight large bus air-conditioning,the aluminum sheet5052-H32 is used to produce air-conditioning＇s shell structure instead of the aluminum sheet 3003-H24.According to the shell structure of bus air-conditioning unit,instead of the original design with a single thickness structure,the fresh profile is designed with different aluminum sheet thickness.The length of the light-weight LNG bus air-conditioning unit is shortened by 8.8%and the weight is lightened by 18.6%.It is verified in enthalpy difference lab that the effect of light-weight design on the refrigeration performance of the large bus air-conditioning unit is in the range of allowable test-error of GB/T21361-2008.
