Two types of variable water flow control were installed to the low flow circulation ground source heat pump (LF-GSHP) multi-split system in the field experiment. It was demonstrated that one variable water flow control that keeps temperature difference between inlet and outlet of the heat pump unit has advantage from the viewpoint of follow capability of water flow control according to cooling output. The average SCOP during cooling season was 4.51 and the value achieved target SCOP of more than 4.5. Additionally, the LF-GSHP multi-split system combined variable water flow control could reduce approximately 80% of electric power consumption compared to the one with constant flow operation.
