A roof-mounted radiant cooling system incorporating a bypass structure, intended for use on liquid natural gas (LNG)-fueled refrigerated vehicles and offering stable dynamic regulation was designed. A model was established using the TRNSYS software package to simulate the operation of this system, and the effects of various factors on the refrigeration performance were analyzed. The quantitative relationship between the LNG flow rate and the ambient temperature was determined and a dynamic regulation strategy proposed. The results of this work show that, when the vehicle is operated at an economical speed, the cooling capacity provided by the system is greater than 1.2 kW, which meets the requirements for a refrigerated vehicle. The dynamic regulation approach developed in this study was found to allow use of the refrigerated vehicle under different climactic conditions and to improve the stability of the cooling system.

LNG冷藏车车顶辐射冷却系统的研究

设计了一种带有旁路结构的屋顶辐射冷却系统,该系统旨在用于液态天然气(LNG)燃料的冷藏车辆,并提供稳定的动态调节。使用TRNSYS软件包建立了一个模型来模拟该系统的运行,并分析了各种因素对制冷性能的影响。确定了液化天然气流量与环境温度之间的定量关系,并提出了动态调节策略。这项工作的结果表明,当车辆以经济的速度运行时,系统提供的冷却能力大于1.2 kW,这满足了冷藏车的要求。
