Ground or water-source heat pumps

PRODUCT CLASS
MINIMUM EFFICIENCY
 
November 2006
Cooling
  Open systems – no greater than 40 kW with 15°C entering water

  Closed loop – no greater than 40kW with 25°C entering water
4.75 COPc




3.93 COPc
Heating
  Open systems – no greater than 40kW with 10°C entering water

  Closed loop – no greater than 40kW with 0°C entering water
3.6 COPh



3.1 COPh

Where

COP = Coefficient of performance – a ratio for both the cooling (COPc) and heating (COPh) modes calculated by dividing the capacity expressed in watts by the power input in watts, excluding any supplementary heat

Requirements for the energy efficiency report, as listed in Schedule IV of the Regulations

  • type of product (ground- or water-source heat pump);
  • brand name;
  • model number;
  • manufacturer;
  • name of the organization or province that carried out the heat pump verification and authorized the verification mark that will be affixed to the heat pump;
  • cooling capacity; in kW (Btu/h);
  • heating capacity; in kW (Btu/h);
  • Air-conditioning and Refrigeration Institute (ARI) classification;
  • cooling coefficient of performance;
  • heating coefficient of performance; and
  • whether the heat pump is to be used in a closed-loop or open system, or both a closed-loop and open system.

APPLIES TO
ground- or water-source heat pumps that are factory-built single packages or split-system matching assemblies that have a cooling or heating capacity of less than 40 kW (135 000 Btu/h) and are intended for application in open- or closed-loop ground- or water-source systems.

TEST STANDARD
CAN/CSA-C13256-1
