AC-83-05-4 -- Computer Simulation of a Lithium Bromide-Water Absorption Heat Pump for Temperature Boosting

Conference Proceeding by ASHRAE, 1983

G. Grossman; K.W. Childs

Full Description

A computer simulation model has been developed to predict the performance of an absorption heat pump for temperature boosting of low-grade heat. The model simulated a single-stage, lithium bromide-water system currently being constructed. The effects of waste heat temperature, cooling water temperature, and solution circulation rate were investigated. The temperature boost and delivered capacity increased almost linearly with an increase in the waste heat temperature or a decrease in the cooling water temperature. The system's coefficient of performance (COP) increases slightly under either of these conditions.
