Measurement of operation of a GSHP system in winter

Tests the operation conditions of ground-source heat pump(GSHP) system in Qingjianghuayuan residential quarters in winter in 2007-2008, and analyses the variation of the parameters including the COP of the HVAC unit and system, the temperature of the underground soil, the heat transfer of underground tube and the water temperature of the inlet and outlet of the unit. The calculation result shows that the energy saving effect is significant for the GSHP system adopted in Wuhan.
