초록

냉 난방 수요에서 일어나는 환경오염의 최소화와 화석연료 소비를 감소시키기 위해서 에너지 회수를 개선시키는 것은 필수적이다. 이러한 점에서 흡수식 열펌프기술은 에너지 절약을 위해서 많은 가능성을 가지고 있다. 흡수식 열펌프는 에너지를 주입하지 않고 폐열의 이용을 높일 수 있는 방법이다. 본 연구에서는 에너지 회수를 위한 재흡수 열펌프 연군를 메탄올-글리세린을 이용하여 수행하였다. 이 물질의 열역학 데이터를 이용하여 재흡수 열펌프의 이론적 열효율 값을 각 기관의 조업 조건에 따라서 계산하였다. $70{\sim}80^{\circ}C$의 산업 폐열 온도를 가지고 $40{\sim}50^{\circ}C$ 승온 시킬 때 열효율 값 0.4 이상을 얻을 수 있었다.

The improvement of energy recovery is mandatory to decrease consumption of fossil fuels and to minimize negative impacts on the environment which originates from large cooling and heating demand. The absorption heat pump technology has a large potential for energy saving in this respect. Absorption heat pump is a means to upgrade waste heat without addition of extra thermal energy. In this study, resorption heat pump for energy recovery has been investigated using methanol-glycerine. The simulated calculation of theoretical thermal efficiency was performed based on the thermodynamic properties of the working fluid over various operating conditions. The thermal efficiency of higher than 0.4 was obtained by raising industrial waste heat, $70{\sim}80^{\circ}C$, by $40^{\circ}C$ in this system.
