· Ground source heat pump system can reduce energy consumption and CO2 emission of heating cooling and hot water supply system in buildings. The capacity of ground heat exchanger is subjected to the restriction of the building or site area and this leads frequently to the situation where the amount of heat supply from ground heat source does not balance the heat demand by whole the For the sake of this example we will use the rating for a Mitsubishi Hyper Heat™ heat pump which is rated to provide sufficient heat output down to -13 degrees Fahrenheit. Heat pumps are rated for "output." In this example when it is 30 degrees out a heat pump will easily produce 100 of its output at the highest efficiency.

· Our manuals account for this and we calculate separate COP s for each stage. For example the four-ton water to air heat pump we looked at above has a COP of 4.10 in stage 1 and 3.89 in stage 2 while in heating mode on a closed loop. You can estimate an average COP by adding these two together and dividing by two (4.20 3.89) / 2 = 4.05 units with a cooling capacity around 5 tons (18 kW). The energy use of new centrifugal compressors dropped considerably from an average of 0.85 kW/ton (4.14 COP) in the late 1970s in the United States to 0.60 kW/ ton (5.86 COP) in 1996. In. 1997 the lowest-energy-use new centrifugal chiller is 0.49 kW /ton (7.17 COP).
