Abstract

<p>The purpose of this research is to examine the behavioral characteristics and energy performance of gas fired using a two-source hot water recovery absorption heat pump/chiller. Gas fired with a two-source hot water recovery absorption heat pump/chiller can simultaneously use two kinds of waste hot water, each with its own temperature zone and flow rate, and can effectively increase energy efficiency. First, a simulation model was constructed for a system equipped with gas fired using a two-source hot water recovery absorption heat pump/chiller in this paper. Then, the energy performance of the air conditioning system equipped with the gas fired using a two-source hot water recovery absorption heat pump/chiller was examined by conducting an energy simulation for an office building with a total floor space of about 5,000 m2 located in Tokyo. In this simulation, it is assumed that waste heat of the co-generation system and solar heat are recovered as two-source hot water in the cooling mode. In the heating mode, only the former is recovered and well water is used as a heat source for the heat pump. As a result, it is found that the COP of the heat source machine was improved and the energy consumption can be reduced significantly by two-source hot water recovery in cooling mode and using well water as a heat source in heating mode. As for the whole system, although the transport energy increases, it is confirmed that the energy saving effect is obtained due to the improvement of the COP of the heat source machine. </p>
