| 摘 要： | 公交车的LNG燃料蕴含大量冷量,目前尚未得到利用.文中就LNG冷能用于公交车空调系统低温送风和空调系统的过冷循环分别进行了优化分析.应用Cleland公式和VB编程计算,结果表明:LNG冷能用于12m公交车低温送风,空调制冷系统COP可提高6.8％～8.6％;将LNG冷能用于12m公交车空调系统的过冷循环,空调制冷系统COP可提高18.2％.

| Abstract: | The LNG fuel in bus contains a lot of cold energy which is wasted currently.In this paper,the utilizations of LNG cold energy for cold air distribution system and subcooled cycle in bus air-conditioning system were analyzed respectively.The results by means of Cleland formula and VB programming show that the COPs of air conditioning system will increase by 6.8%～8.6% and 11.3% when the cold energy is used by cold air distribution system and subcooled cycle respectively in the air-conditioning system for 12m LNG bus. |
