Abstract

A gas engine heat pump (GHP) is the type of compression heat pump that is driven by the motive power from the gas engine. To improve the performance of this GHP greatly, it is necessary to add the heat pump driven by the waste heat from the gas engine to the GHP. This paper suggests the new hybrid heat pump in which the waste heat driven heat pump is combined with the compression heat pump. This system can be driven by the motive power and the waste heat from the gas engine simultaneously. In this paper, the hybrid heat pump whose waste heat driven heat pump is the absorption heat pump is adopted. The working-fluids are ammonia and water. The performance of this hybrid heat pump is analyzed with the simulation. As a result, it was found that gas engine hybrid air conditioning system with the new hybrid heat pump can realize the very high efficiency-primary energy ratio is about 2.4.
