Energy Efficiency Regulations, 2016
Version of section 666 from 2023-06-21 to 2024-08-18:
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.
