This paper presents a computer model of a two-stage lithium bromide absorption chiller that can utilize hot water below 90 ° C as a heat source. The model includes two parts: thermal calculation and heat transfer calculation. The model can be used to quickly and accurately calculate the heat transfer area, the number of pipes, the number of trips, and various consumption indicators when changing any parameters such as external conditions, structural conditions and cooling capacity. Print any intermediate results as needed for research analysis and optimization. This model can be used in computer aided design and related research work.
