摘要
本文介绍了固体吸附式制冷、蒸汽喷射式制冷和吸收式制冷等三种利用余热的热能制冷技术,以及燃料电池的工作原理与特性。针对燃料电池汽车余热浪费大的现状,提出了利用该余热制冷,为燃料电池汽车空调提供冷源的方案,并对其进行了可行性分析。采用热能制冷技术,合理地利用燃料电池汽车余热作为汽车空调系统的驱动热源来实现制冷目的,将带来显著的经济和社会效益,是燃料电池汽车余热回收利用的一种较理想方案。
The work principles and characteristics of fuel cell as well as three categories of heat recovery refrigerationtechnologies-adsorption refrigeration, and jet refrigeration and absorption refrigeration were introduced in this paper. Considering the present conditions that large waste heat exists on fuel cell automobile, the program that cold source was provided for automotive air conditioning with the refrigeration system driven by the waste heat being proposed and its feasibility being studied. If refrigeration technologies, which are driven by heat energy, are reasonably applied to heat recover of fuel cell automobile and the refrigeration effect is obtained, it will be a better program for heat recovery of fuel cell automobile and bring us great economic and social benefits.
