Terms

Term | Definitions
Coefficient of Performance (COP) | A ratio of heating or cooling provided to electrical energy consumed.
Direct Expansion (DX) Geothermal Systems | Use copper lines installed in the earth and filled with refrigerant, instead of using water as a primary loop for heat transfer.
Heat Pump | A refrigeration system that can reverse its refrigerant flow to take either heat from the space it’s serving or from the outdoors or source medium.
SEER | The total cooling output (in British thermal units or Btu) provided by the unit during its normal annual usage period divided by its total energy input (in watt-hours) during the same period.
Water-to-Water Heat Pumps | Typically one of multiple units using fluid circulated in a common piping loop as a heat source/heat sink.
