Abstract　　Represents an energy estimation method for combined heating and cooling system (CHC) operated by heat from cogeneration systems or heating bollers and wasted heat, with consideration of effects of variation in inlet and outlet steam properties of the turbine on the heating and cooling energy consumption. Gives estimation of the primary energy ratio of heating and cooling for systems including the heat pump system and comparison with those for conventional systems.

Keywords　　heating, cooling, cogeneration energy, consumption
