Performance evaluation and trial model of absorption refrigerator using exhaust heat from home CHP

Effective use of exhaust heat from a combined heat and power (CHP) in summer is an issue. This study tries to develop absorption refrigerator using exhaust heat from home CHP. We selected active carbon-ethanol pair for this refrigerator, and cooling capacity analysis showed that adsorption refrigerator using this pair works with high efficiency. To evaluate the effectiveness of introducing absorption refrigerator, the cost and CO2 emission analysis in the case with absorption refrigerator and CHP was conducted. This indicated that absorption refrigerator with CHP has a potential of CO2 emission reduction with low cost. In addition, we developed an experimental system of trial model.
