摘　　要：设计了一套采用活性炭-甲醇为工质对,用燃料电池余热驱动的吸附制冷式汽车空调系统。该空调系统采用了回质循环,本文对该系统进行了数值计算和仿真研究。研究表明:回质是改善系统性能的重要手段,采用回质过程可在热源温度较低的情况下提高系统性能,且能降低外界环境对系统性能的影响;工质对的变化对回质过程不敏感。A fuel cell vehicle air- conditioning system which is driven by waste heat employs activated carbon- methanol as refrigerant. Advanced mass recovery cycle is presented.This paper is about the system simulation study solved by numerical method, Results show that mass recovery is an important means to improve system performance. Mass recovery can improve system performance as the low temperature of vehicle waste heat and reduce the effects on environment. In addition, the effects of refrigerant＇s change on mass recovery are little.
