Abstract
High-COP energy system driven by city gas, named "Hybrid Gas-Eco" which COP is 2.68 by primary energy base, is developed. The system is consist of high efficient gas engine, high efficient absorption chiller-heater driven by waste heat of the engine, and high efficient centrifugal chiller driven by power generated by the engine. It is expected that the system contribute to energy saving, prevention from global warming, and level out the demand for electricity.
