THERMODYNAMIC DESIGN-DATA FOR ABSORPTION HEAT-PUMP SYSTEMS OPERATING ON WATER-CARROL .3. SIMULTANEOUS COOLING AND 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 flow ratio. Tables of possi ble combinations of operating temperatures and concentrations, includi ng flow ratios, Carnot coefficients of performance and enthalpy based coefficients of performance have been presented for water-carrol (lith ium bromide-ethylene glycol, ratio 4.5) absorption systems for simulta neous cooling and heating. The interactions of operating temperatures have been illustrated graphically.
