CSA C500.2:24

Preface

This is the first edition of CSA C500.2, Benchmark energy factor (BEF) assessment of refrigerated facilities . It replaces CSA C500, which was published in 2018 under the title Monitoring and energy performance measurement of industrial refrigeration systems (IRS) using benchmark energy factor (BEF) concepts. CSA C500 has been separated into two Standards: CSA C500.1, which incorporates the requirements for refrigerated spaces and processes; and CSA C500.2, which incorporates the refrigeration requirements at a facility level. The following are the major ways in which this Standard differs from the relevant corresponding parts of CSA C500: a) The Standard has been aligned with more recent BEF standards in terms of document structure, language, terminology, and definitions. b) Essential load and energy determination have been simplified and user inputs have been reduced to make the Standard more user-friendly. c) Essential performance factors used for essential load and energy have been confirmed or updated. d) Required corrections and recommendations identified from the validation study have been incorporated. CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of BC Hydro, Efficiency Manitoba, Electricity Canada, FortisBC, Hydro-Québec, Independent Electricity System Operator (IESO), and the Québec Ministère de l’Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs. This Standard was prepared by the Subcommittee on Industrial Refrigeration Systems, under the jurisdiction of the Technical Committee on Energy Efficiency of Industrial Equipment and Systems and the Strategic Steering Committee on Performance, Energy Efficiency, and Renewables, and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

Scope

1.1 Inclusions

This Standard is intended for refrigerated facilities with the following characteristics: a) refrigerated storage and refrigerated processing facilities for food and beverage products; b) vapour-compression cycle and providing cooling by convection or conduction; c) refrigerated zone volume equal to or greater than 283 m 3 (10,000 ft 3 ); and d) greater than 50% of the facility floor area being refrigerated. Note: See CSA C500.1 for assessing the BEF of the refrigeration system only (e.g., where the non-refrigerated floor area exceeds 50%).

1.2 Exclusions

This Standard is not intended for use for the following systems: a) stand-alone packaged walk-in cooler and freezer units; b) mobile refrigeration units; c) cryogenic freezing processes; and d) grocery and retail facilities.

1.3 Terminology

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

1.4 Dual measurements

The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
