对冷藏保温车隔热性能的探讨

Inquiring Into the Property of Heat Insulation of the Refrigerating Motor Vehicle

冷藏车厢体传热系数K值的大小及变化情况直接影响到冷藏保温车的隔热性能,而目前有关标准中及实测得到的K值均为静态参量。根据实践经验和有关参考资料,对K值的构成进行了分类,并探讨了每个组成部分对冷藏保温车隔热性能的影响。

Value of heat transfer coeffient K and its variation directly effect the heat insulation property of a refrigerating motor vehicle. The value K obtainable now from relevant standards and practical testing are parameters in static status, which is not suitable to be directly utilized. Based on practical experience and related reference material, cgmpositions of value K have been analysed and sorted, and the effect of each component on insulating property of the refrigerating motor vehicle has been studied.
