The prediction of the coefficient of performance of vapour compression heat pumps

Feasibility of using vapor compression refrigeration system for cooling steam plant condenser

“…These experiments were done for temperature lift T c À T e in the range of 20-50°C and for evaporating temperature in the range of 2-4°C. The mechanical and electrical efficiencies were taken 0.85 and 0.9, respectively, as reported in [22].…”
