Abstract
A novel home cogeneration system that is available to air conditioning use has been proposed, and its feasibility has been investigated theoretically. Waste heat from PEFC that is used as a generator is usually utilized as a hot water in micro cogeneration. But, in Japan, in order to reduce increasing power consumption for air conditioning in residential use, it is indispensable to develop a home cogeneration system that can be used for air conditioning. Therefore, a single effect absorption chiller heater was adopted as waste heat recovery equipment. The absorption chiller heater is driven by the low temperature waste heat from the PEFC and is available for air conditioning. Their performances and efficiencies were predicted quantitatively by computer simulation. Furthermore, air conditioning performances of the absorption chiller heater were calculated with considering real weather conditions and were cleared for cooling water temperature changes.
