臭化リチウム水溶液の熱力学性質 第1報-沸点圧力の精密測定 Thermodynamic Properties of LiB/H_2O Solution 1st Report : Measurements of Bubble-Point Pressures
Although most of the absorption refrigeration/heat pump systems use LiBr/H<SUB>2</SUB>O solution for absorbent/refrigerant pair, there exist only a limited number of reliable sets of data on the bubble-point pressures of LiBr/H<SUB>2</SUB>O solution. The objective of the present study is to reveal the concentration and temperature dependence of bubble-point pressures of LiBr/H<SUB>2</SUB>O solution over a wide range of parameters so as to provide more precise set of thermodynamic property data for advanced design of the absorption refrigeration/heat pump equipments.<br>A total of 44 bubble-point pressures have been measured along seven concentration isopleths of 20, 30, 40, 45, 50, 58 and 60 wt%LiBr solution which cover the range of temperatures 283-413 K and of pressures up to 300 kPa. The experimental uncertainties of temperature, pressure and concentration measurements were not greater than ±20mK, ±0.1 kPa and ±0.1wt%, respectively.
