THERMODYNAMIC DESIGN-DATA FOR ABSORPTION HEAT-PUMP SYSTEMS OPERATING ON WATER-CARROL .2. HEATING

The Gibbs phase rule and thermodynamic properties of the working pair limit the choice of operating temperatures. For any combination of tem peratures, the concentrations in the absorber and the generator and he nce the flow ratios are fixed. For any particular working pair, the co efficient of performance is related to the how ratio. Tables of possib le combinations of operating temperatures and concentrations, includin g flow ratios, Carnot coefficients of performance and enthalpy based c oefficients of performance have been presented for water-carrol (lithi um bromide-ethylene glycol) absorption systems for heating. The intera ctions of operating temperatures have been illustrated graphically.
