The Theoretical Analysis And Simulation Calculation Of The Single-effect Lithium Bromide Absorption Refrigeration System

Solar energy as the heat source of the absorption cooling system,has become relatively succeed of the solar cooling.Single-effect lithium bromide absorption cooling system will have a broad prospects for the development of refrigeration technology,because of its low operating heat source and high cooling efficiency.It's vitally important for physical parameters of Lithium bromide aqueous solution and Saturated water(vapor)to make theoretical analysis and simulation calculations.We gain the physical parameters of LiBr and Saturated water(vapor)by looking up the chart or curve indirectly as usual.In order to optimization of system design and simulation calculation,In this paper,we tried to fit curve and check the fitted formula,and then to get the relative accuracy of the physical parameters of the formula for the future research applications.Based on energy conservation and mass conservation and other physical laws,We have had a detailed theoretical analysis and study on the Single-effect lithium bromide absorption refrigeration system.Set up the simulation model of the whole refrigeration system and each component,Which provides a good theoretical basis for single-effect absorption refrigeration system.We have had the thermodynamic calculation of the state parameters of the system with cooling capacity of 14kW,to ensure the system meets heat balance.Then by means of the calculation of heat transfer on the system to design structure.In order to explore the factors influence on system performance,Based on the simulation model established in this paper,we changed a single variable,calculated the heat source temperature,the cooling water inlet temperature and the cold water outlet temperature and other physical parameters,which impact on the performance of Single-effect Lithium Bromide Absorption Refrigeration System.It has some important reference value for the system for its design and study.Solar energy as a rich natural resources,combining the refrigeration system and the solar collector system,which would be the most promising aspect of the single-effect lithium bromide absorption refrigeration system.
