| Abstract |
The effects of applying the micro CHP system to the domestic sector in Korea were investigated using annual cooling and heating demand data. Four prime movers, micro gas turbine, PEMFC, gas engine and Stirling engine, were compared for three operational modes. Two way buy-back was assumed for both electricity and heat. The Stirling engine gave the lowest CO2 emission per energy for 300kWh monthly electricity production. However, PEMFC became more effective when considering PURPA criteria. PEMFC generated the least greenhouse gas with higher electrical efficiency for cooling. The Stirling engine, however, became competitive for heating with higher total efficiency |
