Thermal Design Analysis of an Absorption Heat Transformer for using Waste Hot Water
- 발행 : 1985.12.01
초록
A computer program for thermal design analysis has been developed to predict the performance of an absorption heat transformer. The effects of temperature boost, cooling water temperature and effectiveness of components on the performance were investigated. Not only the detailed thermodynamic states such as temperatures, concentration of the solution, and mass flow rate at each point of the process but also the heat transfer rate in each component could be easily determined with given input parameters. The system's coefficient of performance (COP) was seen to increase with increased effectiveness of components, decreased temperature boost of hot water, and decreased cooling water temperature. Even though the COP increases with increased effectiveness of the components, the variation in the COP is not substantial above certain values of the effectiveness. A reference design point can be selected on this basis.
