Energy Efficiency Regulations, 2016 — 657
Definitions 657 The following definitions apply in this Subdivision. A dd represents, with respect to display door assemblies, the surface area in m 2 (square feet). ( A pp ) A nd represents, with respect to a door assembly other than a display door assembly, the surface area in m 2 (square feet). ( A pa ) annual walk-in energy factor means the ratio of total heat removed from an enclosed space, excluding heat generated by the operation of the walk-in refrigeration system, to the total energy input of the walk-in refrigeration system during a one-year period, expressed in watt-hours per watt-hours. ( facteur énergétique annuel de la chambre froide ) dedicated condensing refrigeration system means a dedicated condensing unit, a single-package dedicated system or a matched refrigeration system. ( unité de condensation dédié ) dedicated condensing unit means a positive displacement condensing unit that (a) has one or more compressors, a condenser and one refrigeration circuit; and (b) is designed to serve one refrigerated load. ( unité de condensation dédiée ) (c) [Repealed, SOR/2019-163, s. 49] display door assembly means a walk-in door assembly that is designed for product display and that has 75% or more of its surface area composed of glass or other transparent material. ( assemblage de porte de présentation ) envelope means (a) the portion of a walk-in cooler or walk-in freezer that isolates the interior, refrigerated environment from the ambient, external environment; and (b) all energy-consuming components of the walk-in cooler or walk-in freezer that are not part of its refrigeration system. ( enveloppe ) floor panel means a walk-in panel that is installed, or designed to be installed, as the floor of a walk-in freezer. ( panneau de plancher ) freight door assembly means a walk-in door assembly, other than a display door assembly, that is 1.22 m (4 feet) or more in width and 2.44 m (8 feet) or more in height. ( assemblage de porte de quai de chargement ) matched refrigeration system means a refrigeration system that includes a dedicated condensing unit and one or more unit coolers with which it is sold. ( système de réfrigération apparié ) Net Refrigeration Capacity or (q net ) is the net refrigeration capacity available for space and product cooling. ( puissance frigorifique nette ou q net ) passage door assembly means a walk-in door assembly that is not a display door assembly or a freight door assembly. ( assemblage de porte de passage ) RSI-value means, in respect of a walk-in panel and a walk-in door assembly, its thermal resistance, in square metre kelvins per watt (m²·K/W). ( valeur-RSI ) R-value means, in respect of a walk-in panel and a walk-in door assembly, its thermal resistance, expressed in square foot Fahrenheit per Btu/h (ft 2 ·°F·h/Btu). ( valeur-R ) single-package dedicated system means a single-package refrigeration system that has (a) one or more compressors, one condenser and a means of forced circulation of refrigerated air; and (b) components by which heat is transferred from air to refrigerant without any components that are external to the system imposing resistance to the flow of the refrigerated air. ( système dédié monobloc ) structural panel means a walk-in panel that is installed, or is designed to be installed, as the ceiling or a wall of a walk-in cooler or walk-in freezer. ( panneau de structure ) 10 C.F.R. Appendix A means Appendix A to Subpart R, Part 431 of Title 10 to the United States Code of Federal Regulations , entitled Uniform Test Method for the Measurement of Energy Consumption of the Components of Envelopes of Walk-In Coolers and Walk-In Freezers , as amended from time to time. ( appendice A 10 C.F.R. ) 10 C.F.R. Appendix B means Appendix B to Subpart R, Part 431 of Title 10 to the United States Code of Federal Regulations , entitled Uniform Test Method for the Measurement of R-Value for Envelope Components of Walk-In Coolers and Walk-In Freezers , as amended from time to time.
