Abstract
A hybrid air conditioning system consists of a gas engine as a driving source and a hybrid refrigerator which can be driven by waste heat and motive power simultaneously. It can improve the efficiency of the gas engine heat pump greatly because it uses waste heat from the gas engine. This paper aims to estimate the performance of this hybrid air conditioning system by the simulation. The objective hybrid refrigerator is composed of the single-effect absorption type and single-stage compression type refrigerator. The working fluids are not shared for each refrigerator. The static simulation model of the hybrid air conditioning system is constructed and the performance is investigated using this model. To evaluate the system performance, the heat and power ratio is used. As a result of the simulation, higher performance part load can be realized by making the heat and power ratio of the hybrid refrigerator agree with that of gas engine.
