Abstract
에너지 절약과 지구 환경문제에 대한 관심이 증가함에 따라서, CFCs와 HCFCs와 같은 냉매가 필요없는 흡수식 냉난방기가 최근 많은 관심을 얻고 있다. 공기냉각방식의 흡수식 냉난방기는 소형장치를 위해 개발되었으나, 용해도와 증기압 등의 높은 물리화학적 특성들을 요구한다. 본 연구의 주된 목적은 5성분 작동매체의 가능성을 평가하는 것이다. LiBr+LiNO3+LiCl+ZnBr2 시스템을 선택하였고, 실험을 동해서 최적의 몰비가 LiBr:LiNO3:LiCl:ZnBr2= 5:1:2:2.5로 선정되었다. 용해도는 68~76wt%에서 측정하였고, 증기압은 293.15K~324.15K에서 측정하였다. 실험 데이터는 Antoine-type 식으로 상관관계를 지었고, 용해도와 증기압의 측정 값들을 통해서 P-T-X 선도를 작성하였다. In accord with the increasing concern about the energy saving and the global environmental issues, the absorption chiller is currently being considered very attractive since they do not require refrigerants such as chlorofluorocarbons(CFCs) and hydrochloro-fluorocarbons(HCFCs). Air-cooled absorption chiller is being developed for small scale but this unit requires high physical and thermal properties such as solubilities, vapor pressure and so on. The main purpose of this study is evaluating the possibilities of 5 components working fluid. LiBr+LiNO3+LiCl+ZnBr2 system was selected and the optimum mole ratio was experimentally determined to be LiBr:LiNO3:LiCl:ZnBr2=5:1:2:2.5. The solubilities were measured at concentrations from 68~76wt% and the vapor pressures were measured at temperatures from 293.15 to 423.15K. The experimental data was correlated with an Antoine-type equation and P-T-X chart was constructed through the measurements of solubility and vapor pressure.
