Heating test of the low flow circulation ground source heat pump (LF-GSHP) multi-split system was carried out in the field and approximately 4.0 of SCOP were obtained on the some conditions. Also, antifreeze solution was applied as the thermal medium instead of water and heating and cooling test were conducted. The LF-GSHP multi-split system with antifreeze solution decreased only less than 15% of SCOP compared to the one with water in the both of heating and cooling experiment. In addition, daily average SCOP during heating operation was 3.33.5 even in the middle of winter season. These show that the LF-GSHP multi-split system has great possibility of adaptation also in the cold region.
