Energy Efficiency Regulations, 2016

Marginal note:Energy efficiency standards

• 666 (1) The energy efficiency standards set out in column 2 of the table to this section apply to walk-in refrigeration systems described in column 1 that are manufactured during the periods set out in column 3.

• Marginal note:Testing standard

  (2) A walk-in refrigeration system complies with the energy efficiency standard if it meets that standard when tested in accordance with testing procedures established by 10 C.F.R. Appendix C that are applicable to a walk-in refrigeration system as defined in section 657.
