Abstract
The objective of this work is thermal and cost assessment of a micro-capacity absorption refrigeration system. The simple effect absorption refrigeration system we modeled in EES (Engineering Equation Solver), in order to recovery the exhaust energy provided by the exhaust gases of an internal combustion engine. The exergy analysis of the cycle components we performed considering the heat transfer modelling. The cost of the produced cold we computed. A cold of up to 17.9 kW was produced at the maximum engine load of 37.5 kW at a unit cost of 0.058 US$/kW. The minimum engine load was required for the operation of the 22.5 kW cycle, the cold produced was 9.7 kW at a unit cost of 0.164 US$/kW.
