摘要
本文根据物质基本的物理和热力学性质,选择了LiBr/H_2O、LiBr-ZnCl_2/H_2O、LiBr-ZnCl_2-CaBr_2/H_2O和LiCl/H_2O等几种增温型吸收热泵工质对,在实验室装置上进行了实验研究。结果表明,LiBr-ZnCl_2-CaBr_2/H_2O混合工质对循环流率比低,增温效果和性能系数与LiBr/H_2O基本相近,是一种值得开发和具有实用价值的无机物工质对。
The systems of LiBr/H_2O, LiBr-ZnCl_2/H_2O, LiBr-ZnCl_2-CaBr_2/H_2O and LiCl/H_2O heve been selected as the working pairs of absorbtion heat transformer, according to the physical and thermodynamic properties of these substances. The experimental studies has been performed in the laboratory. The results stated that the mixed working pair of LiBr-ZnCl_2-CaBr_2/H_2O is a promising and valuable inorganic working pair, because it has lower cycleflow-rate ratio, higher boosting temperature and its coeffecient of performance is similer to the system of LiBr/H_2O
