小規模施設向け熱エネルギ供給設備における各種システムの性能比較

抄録

This paper compares the performances of 5kW-class “Air source heat pump system (ASHP) and Ground source heat pump system (GSHP)” at the same time and the same condition at semi-cold region. GSHP is more efficient than ASHP, but there is little evidence. As a result, the total energy consumption efficiency of ASHP was 29% to 40% higher than the that of GSHP. Therefore, 5kW-class heat pumps should be improved the efficiency.
