SUBDIVISION CLarge Heat Pumps

Marginal note:Definitions

 The following definitions apply in this Subdivision.

AHRI 340/360

AHRI 340/360 means the AHRI standard ANSI/AHRI 340/360-2007 entitled Performance Rating of Commercial and Industrial Unitary Air-Conditioning and Heat Pump Equipment. (AHRI 340/360)

CSA C746-98

CSA C746-98 means the CSA standard CAN/CSA-C746-98 entitled Performance Standard for Rating Large Air Conditioners and Heat Pumps. (CSA C746-98)

IEER

IEER means the integrated energy efficiency ratio, expressed in British thermal units per watt hour, that constitutes a single number cooling part-load efficiency metric of a large heat pump. (IEER)

large heat pump

large heat pump means a commercial or industrial unitary heat pump that is intended for air-conditioning and space-heating applications and that has a cooling capacity of at least 19 kW (65,000 Btu/h) but less than 223 kW (760,000 Btu/h). It does not include a single package vertical heat pump. (thermopompe de grande puissance)

Marginal note:Energy-using product
  •  (1) A large heat pump is prescribed as an energy-using product.

  • Marginal note:Limits

    (2) However, for the purposes of sections 4, 5 and 197, a large heat pump is not considered to be an energy-using product unless

    • (a) in the case of a large heat pump with a cooling capacity that is less than 70 kW, it is manufactured on or after December 31, 1998; and

    • (b) in the case of a large heat pump with a cooling capacity that is greater than or equal to 70 kW, it is manufactured on or after January 1, 2010.

Marginal note:Energy efficiency standards
  •  (1) The energy efficiency standards set out in column 3 of Table 1 to this section apply to large heat pumps described in column 1 that are manufactured during the periods set out in column 4 and that have no heating section or have an electric heating section.

  • Marginal note:Energy efficiency standards

    (2) The energy efficiency standards set out in column 3 of Table 2 to this section apply to large heat pumps described in column 1 that are manufactured during the periods set out in column 4 and that have a heating section other than an electric heating section.

  • Marginal note:Testing standard

    (3) A large heat pump complies with the energy efficiency standard set out in column 3 if it meets that standard when tested in accordance with testing procedures established by the standard set out in column 2 that are applicable to a large heat pump as defined in section 195.
