摘要
LNG(液化天然气)作为绿色汽车燃料,可以减少汽车尾气排放造成的空气污染。此外,LNG在汽化、温升的过程中释放大量的冷能。本文提出利用乙二醇溶液做冷媒的蓄冷系统对该冷能进行回收。并将回收的冷能用于低温冷藏链中的冷藏运输过程。系统参数计算结果表明:回收的冷能满足中短途小型冷藏车的冷负荷需求。
Air pollution arisen by auto exhaust gas will decrease when LNG (Liquefied Natural Gas) is used as the vehicle fuel. In addition, plenty of cold energy will be released during gasifying and temperature increasing of LNG. Recovering and utilizing the cold energy in cold storage vehicle have been put forward in this paper by cold-storage system of glycol. The parameter design and the results indicate that the cold energy recovered is matched with the need of minitype low temperature cold storage vehicle.
