Méthodes d'essai pour l'évaluation en laboratoire des performances des ventilateurs-récupérateurs de chaleur/énergie

1.1.1
This Standard applies to packaged heat/energy-recovery ventilators (HRVs/ERVs) that consist of factory-assembled elements, including fans or blowers, in which heat or heat and moisture are transferred between two isolated airstreams.

1.1.2
This Standard specifies laboratory methods of test and procedures for rating the apparent effectiveness and heat-recovery efficiency of HRVs/ERVs. Procedures for determining air movement capabilities and the leakage of air from one airstream to another are also included.

1.1.3
Packaged HRVs/ERVs that use a refrigeration cycle or circulating fluid to transfer heat between two isolated airstreams may be rated using this Standard.

1.2
In CSA Standards, "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; "may" is used to express an option or that which is permissible within the limits of the standard; and "can" is used to express possibility or capability.

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
