흡수식냉난방기용 다성분 리튬염 작동매체의 증기압 및 용해도 측정 = Measurement and Analysis on the Physical Properties of Multi Lithium Salts Solution in Absorption Heat - Pumps

다국어 초록 (Multilingual Abstract)

In an effort to obtain high efficiency in air cooled absorption heat pump, a new working fluid has been developed with the addition of LiNO₃ and LiCl to the conventional solution of LiBr-H₂O. The solubility and vapor pressure of the multicomponent salts solution developed in this work were measured and compared with the results of LiBr-H₂0 solution. It was observed that there exists an optimal molar ratio of the inorganic salts in terms of solubility. The molar ratio of LiBr and LiNO₃ was found to be about 5 : 1 in the LiBr-LiNO₃ mixture, and in the case of LiBr-LiNO₃-LiCl mixture, the molar ratio of LiBr, LiNO₃ and LiCl was found to be around 5 : 1 : 2. The vapor pressure of the multicomponent salts solution of the optimal molar ratio was increased with adding LiNO₃, while decreased with adding LiCl.
