CSA C500-18 (R2022)

Preface:

This is the first edition of CSA C500, Monitoring and energy performance measurement of industrial refrigeration systems using benchmark energy factor concepts.

CSA acknowledges that the development of this Standard was made possible in part by the financial support of BC Hydro, the Canadian Electricity Association (CEA), Hydro Quebec, Independent Electricity System Operator, Manitoba Hydro, Natural Resources Canada (NRCan), Nova Scotia Department of Energy, Efficiency Nova Scotia, and Ontario Ministry of Energy.

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 to be used for industrial refrigeration systems using refrigerants such as R22, R404A, R448a, R410a, and ammonia (R717) and with the following characteristics:
a) facility types including storage warehouses, distribution facilities, and refrigerated processes;
b) facility storage volume equal to or greater than 283 m3 (10,000 ft3); and
c) process cooling capacity of a minimum of 70 kW (20 TR).

1.2 Exclusions
This Standard is not intended for use for the following systems:
a) stand-alone packaged walk-in cooler and freezer units; or
b) mobile refrigeration units.

1.3 Dual dimensions
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.

1.4 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.
