摘　　要：对太阳能溴化锂吸收式空调系统进行理论研究与分析时,需要知道溴化锂水溶液各物理量之间的关系。依据2013ASHRAE Handbook和《热力学》中的溴化锂水溶液温度-压力-浓度关系曲线,利用最小二乘法,拟合出计算关联式。通过将其值与其他文献提供的公式计算值进行比较与讨论,表明本文拟合公式计算简单、精确度高且适用范围广,可应用于太阳能溴化锂吸收式空调系统的理论分析与研究。The relationships among each physical quantity of lithium bromide solution should be known when analyzing the solar lithium bromide absorption type air-condition-ing system. According to the curve of the temperature-pressure-concentration stated in the 2013 ASHRAE Handbook and the Thermodynamics the least square method is used to fit out the suitable correlation. Comparing the calculated value and the values calculated ac-cording to the correlation from other documents, it can be indicated that the correlation is easy to calculate with high accuracy and wide scope of application, which can be applied to the theoretical analysis and study on the solar lithium bromide absorption type air-conditioning system.
