Kurzbeschreibung (Abstract)
A breadboard prototype of an absorption system for truck refrigeration using heat from the exhaust-gases was designed, built and tested. Measured COP values of the unoptimized single-stage ammonia-water absorption cycle varied between 23 and 30%, but system modeling shows that this can be improved to values considerably over 30%. Computer simulation for the system included cycle analysis as well as component modeling, using a detailed two-fluid model for flow of the ammonia-water mixture in the condenser and absorber. This detailed model was also validated using test data. In addition, the recoverable energy of the exhaust gases was analyzed for representative truck-driving conditions for city traffic, mountain roads and flat roads. The results show that the system is promising for long distance driving on flat roads.
