Preface

This is the fifth edition of CSA C439, Laboratory methods of test for rating the performance of heat/ energy-recovery ventilators. It supersedes the previous editions, published in 2009, 2000, 1988, and 1985.

This Standard applies to packaged heat/energy-recovery ventilators.

Scope

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.

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.

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