Computer Simulation Of Lithium Bromide-water Refrigerator With Heat-Pipe Driven By Exhaust Gas

Lithium bromide-water refrigerator with heat pipe driven by waste heat of flue gas transfers waste heat from flue gas to high pressure lithium bromide-water generator by high efficient heat pipe heat exchanger. At present, prototype has been in use.The mature software has not existed for the complicated system design. Manual computation consumes much time. Moreover the performances of system in varying duty are not known. The cost of experiment is too high. The main work of this paper is compiling the computer aided design and simulation software of this kind of model. The software has six modules: thermo physical property of working medium, design of heat pipe lithium bromide-water generator driven by waste heat, system design of single or double lithium bromide-water refrigerators with heat pipe, performance simulation of single or double lithium bromide-water refrigerator with heat pipe in varying duty, thermodynamic parameters of each state, thermodynamics analyses. The software makes the design more convenient and correct. It can be used to compare the design of multiparameter and select deferent design methods according to different needs. Also, it lays a foundation for dynamic simulation of system. By this work, the whole system design and simulation software has been constructed. Comparison between simulation result and expriment data shows excellent agreement. This software satisfies effectively the requirement of project. This makes prediction more convenient and accelerates popularize of this kind of model.
