Characteristics Analysis of an Absorption Air Conditioning System both by using Solar Thermal Energy and Small Gas Engine Waste Heat

Abstract

Lately, in Japan, energy saving and renewable energy utilization are strongly required from view point of both global warming protection and energy security. But the amount of energy consumption in the building sector has remarkably increased. Therefore, the Building Energy Efficiency Act was enforced on April of 2016 in order to strengthen energy efficiency measures on building. The authors have started the measurement of energy consumption for experimental apartment house “NEXT21” in order to investigate feasibilities of energy saving and renewable energy introduction. In this report, the actual performances of coupling air conditioning system consist of hot water driven single effect absorption refrigerator and gas fired doubled effect absorption chiller was mainly investigated.
