scope:
This Standard applies to packaged heat-recovery ventilators that comprise factory-assembled element including fans in which heat is transferred between two isolated aistreams, and that are intended for use in ducted supply and exhaust systems.
This Standard prescribes methods for rating the sensible and total thermal effectiveness, the air-movement capcities, and the leakage of air from one aistream to another for head-recovery ventilators.
All units tested under this Standard shall have a maximum rated capacity of no less than 25 L/s (50 ft3/min) and nother more than 200 L/s (400 ft3/min) with a tolerance of ±5% for ±5 L/s (±10 ft3/min), whichever is greater. The laboratory facilities shall be capable of testing a unit in the complete range between the minimum and maximum reated air-halding capacity of that unit.
This Standard does not apply to mechanical vapour-compression equipment (eg, heat pumps).
The values given in parentheses are provided for information only.
Purpose
The purpose of this Standard is to
(a) establish a uniform method of testing for performance data;
(b) Specify data, calculations to be used, and report data; and
(c) List and define terms used in this Standard
