Exergy analysis of heat pipe for waste heat lithium-bromide refrigerator driven by exhaust gas of diesel engine

At present, the industrial process releases a large mount of waste heat, causing loss of usable energy and environmental pollution. In the paper, a novel absorption refrigeration cycle with lithium bromide water as working fluid pair is introduced. This refrigeration system utilizes heat pipe to callback the waste heat. An exergy analysis is carried out on the result of actual measurement. The results indicate that the heat pipe for waste heat absorber of cycle callbacks the waste heat effectively and exergy efficiency of the whole system is improved.
