Abstract
Solar-assisted refrigeration systems have been proposed for application in Goldstone energy conservation projects. This article describes and analyzes the dynamic simulation and the computer modeling procedure of one of these systems, namely a lithium bromide/water absorption refrigeration system. A new analytical expression that fits the three-dimensional surface of LiBr concentration, refrigerant temperature and solution temperature in the range of interest from 0.50 to 0.65 kg LiBr/kg solution is presented with a standard deviation of +0.2 percent. This will save considerable computing time and effort required for evaluation of system performance. A numerical example from typical running conditions is added to show the relative weight of each parameter used together with the sequence of program steps followed. The results from this simulation are heat rates, line concentrations, pressures and the overall coefficient of performance.
