메탄올-글리세린 시스템을 이용한 흡수 열 펌프의 이론적 성능
Theoretical Performance of an Absorption Heat Pump Using Methanol-Glycerine System
에너지 회수를 위한 흡수 열 펌프 시스템은 LiBr 수용액을 이용하여 왔다. 이 용액은 결정화와 부식의 단점 때문에 본 연구에서는 메탄올-글리세린을 선택하였다. 이 물질의 상평형 열역학 data를 이용하여 흡수 열 펌프의 성능 계수(COP) 값을 각 기관의 조업조건의 변화에 따라 계산하였다. 난방을 위한 COP 값은 1.3-1.6이고 냉방을 위한 COP값은 0.3-0.7을 얻었다.
An absorption heat pump system for energy recovery has been using aqueous solutions containing lithium bromide. Because of problems such as crystallization and corrosion in these solutions, methanol-glycerine(working pair) was selected. The calculation of the theoretical coefficient of performance(COP) for the absorption heat pump was carried out based on the thermodynamic properties of this working pair over various operating conditions for each part of the system. The values of COP are as follows. The COP for heating 1.3-1.6. The COP for cooling 0.3-0.7.
