本文提出了利用电子计算机进行溴化锂制冷机优化设计的一种方法-最佳点探索法。根据这一方法所编制的计算程序在进行溴化锂制冷机热力计算的同时可以完成循环参数的最佳选择。进而实现优化设计。为了能适应国内情况的使用,笔者特根据国产溴化锂水溶液物性实测数据进行回归得到可以适用的有关溴化锂水溶液的物性方程。 In this paper, a method of optimal design of lithium bromide refrigerator using electronic computer is put forward. According to this method of preparation of the calculation program in the lithium bromide thermodynamic calculation can be completed while the cycle parameters of the best choice. Then to achieve optimal design. In order to be able to adapt to the use of the domestic situation, the author of the special Lithium bromide aqueous solution measured according to the actual data obtained regression applicable lithium bromide aqueous solution of the physical equation.
