Absorption Heat Pump Simulation and Studies: A Modular Computer Simulation of Absorption Systems. Final Report

摘要

A computer simulation program for absorption systems has been developed in a flexible and modular form, which makes it possible to simulate various configurations with different working fluids. The user supply input containing information about given flow rates and temperatures, as well as characteristics of the various subunits of the system. In addition, the user must convey to the computer an image of the cycle in question. The program calculates the temperature, composition, flow rate, and pressure at each state point of the system and the heat quantities at each unit, from which the coefficient of performance may be determined. The program has been tested on single- and double-stage absorption heat pumps and heat transformers with lithium bromide-water and water-ammonia as the working fluids. Results have been compared with experimental data from tests of a lithium bromide-water heat transformer, giving good agreement. (ERA citation 11:034193)
