A simulation model of absorption heat pump had been developed by analyzing mass and heat balances and heat trans -fer relationships of the overall system and its components .The model was used for analyzing the influence of temperature of circu-lating water and heating network water and turbine extraction pressure on system COP during a power plant heat pump unit opera-tion.Obtain the variation range of turbine extraction pressure in different working conditions in order to keeping the system COP a-bove 1.66 by simulation.
