Abstract

80%에서 120%로 증 가할 때 흡수액 농도가 56%, 55%, 54%, 53%에서의 열교환량은 각각 30%, 33%, 34%, 37% 정도 증가하 였다 또한 고온재생기의 흡수액 입구농도가 . 56%, 55%, 54%, 53% 일 때 공기측 입구온도가 170 o C에서 210 o C로 증가함에 따라 고온재생기의 열교환량은 각각 140%, 160%, 220%, 224% 정도 증가하였다 . Abstract: An absorption chiller-heater using only a natural refrigerant hardly causes any environmental pollution. In an absorption chiller-heater, the performance of its high-temperature generator, which uses exhaust gases, is essential to achieving superior system performance. To investigate the performance of such a high-temperature generator, a laboratory-scale high-temperature generator working with exhaust gases was designed and tested. Changes in the performance of the high-temperature generator as a function of inlet conditions of the absorbing solution, such as air inlet temperature and mass flow, were investigated. It was observed that when the air mass flow rate ratio was increased from 80% to 120%, the heat capacity was increased by 30%, 33%, 34%, and 37%, respectively. Additionally, when the air inlet temperature was elevated from 170°C to 210°C for absorption solution concentrations of 56%, 55%, 545, and 53%, the heat capacity increased by 140%, 160%, 220%, and 224%, respectively.
