Large air conditioners and heat pumps

Update August 2016 (Original May 2016)

Technical bulletin on amending the standard

Webinar - June 2016

This update is to correct an error in the original bulletin from May 2016 for evaporative-cooled large air conditioners. Table 3 has been added to this updated bulletin outlining the proposed MEPS for evaporative-cooled units which aligns with requirements in the US. In the original May 2016 bulletin, Table 2 mistakenly included the MEPS for water-cooled and evaporative-cooled units.

On April 30, 2016, Natural Resources Canada's Office of Energy Efficiency issued a Notice of Intent to align Canada’s Energy Efficiency Regulations (the Regulations) for large air conditioners and heat pumps (Large AC/HP) with standards in the United States (U.S.). This technical bulletin has been released to initiate the consultation process and to collect stakeholder views on the requirements being considered for Large AC/HP.

Input received during this stage of the process will inform the development of the Amendment 14 proposal.  In addition, the department will undertake a cost-benefit analysis using the best-available Canadian market data to assess the economic and environmental impacts of aligning these standards and to ensure Canadian consumers and businesses benefit from its implementation.

The Government of Canada intends to pre-publish a regulatory proposal in the Canada Gazette, Part I within approximately one year of this bulletin.

Background

Large air conditioners and heat pumps have been regulated in Canada since 1998 and were last updated in Canada in 2010. On May 16, 2012, the U.S. Department of Energy (DOE) published a direct final rule adopting amended energy conservation standards for water-cooled and evaporative-cooled commercial package air-conditioning and heating equipment. Subsequently on January 15, 2016 the U.S. DOE published a direct final rule adopting amended energy conservation standards for air-cooled commercial package air-conditioning and heating equipment – Tier 1 effective January 1, 2018 and more stringent Tier 2 effective January 1, 2023.

Natural Resources Canada (NRCan) is considering increasing the MEPS for water-cooled and evaporative-cooled products to align with the MEPS in the US for those classes of products.  NRCan is also considering increasing the MEPS for air-cooled products to align with Tier 1 of the US DOE ruling that is coming into force on January 1, 2018.  In addition, Tier 2 levels may be considered in a future amendment.

Product description

This proposed Regulatory change applies to factory assembled commercial and industrial unitary air conditioners and heat pumps ranging in capacity from 19 kW (65,000 Btu/h) to 223 kW (760,000 Btu/h). It does not include a single package vertical air conditioner.

Energy performance test procedure

NRCan is proposing that the following energy performance test procedure be referenced:

  • United States Code of Federal Regulations (CFR), Title 10, Part 431, Subpart F, Appendix  A until the revised CSA standard C746-06 - Performance Standard for Rating Large and Single Packaged Vertical Air Conditioners and Heat Pumps is finalized and published, which is expected before publication in Canada Gazette, Part ll.

Effective dates

These Regulations will come into force six months after the date of publication in the Canada Gazette, Part II.

NRCan proposes that the updated standards will apply to products manufactured on or after January 1, 2018.

Labelling requirements

NRCan is not proposing labelling requirements for Large AC/HP at this time.

Verification requirements

There is no change proposed for the energy efficiency verification requirements for this product.

Reporting requirements

Energy efficiency reports

There is no change proposed to the reporting requirements for Large AC/HP.

The Regulations apply to products imported or shipped inter-provincially for sale or lease in Canada. This report must be submitted, by the dealer, to NRCan before the product is imported into Canada or traded interprovincially for the first time.

Import reports

There is no change proposed to import reporting requirements for Large AC/HP.

Comments invited

The purpose of this bulletin is to provide stakeholders with technical details required to comment on the requirements under consideration for Large AC/HP. 

Additional information on Canada’s Energy Efficiency Regulations including a current list of Standards Council of Canada accredited certification bodies can be found in the Department’s website.
