Abstract
The characteristics of a diffusion absorption refrigerator driven by the waste heat from a diesel engine exhaust were investigated. The heating unit of the diffusion absorption refrigerator was modified to be able to utilize the waste heat from engine exhaust. A series of tests were conducted including the original refrigerator driven by the alternating current (AC) power, direct current (DC) power, liquid petroleum gas (LPG), and the waste heat from a diesel engine exhaust gas. The performances of the modified refrigerator driven by the waste heat from engine exhaust were compared with that of original performances of the refrigerator driven by AC, DC, and LPG. The results showed that the performances of the refrigerator driven by engine exhaust were better than that of the original refrigerator driven by AC and DC power. The results showed that the exhaust heat from diesel engine is an applicable, attractive energy resource for diffusion absorption refrigerator.
