HRV fresh air supply ok?
HRV fresh air supply ok?
(OP)
Hi,
For a radiant floor heated industrial building in an extreme cold climate, what's the best way to supply fresh air into the room?
Is a HRV unit supplying fresh air (20cfm/p) into the room good enough? Or do we need reheat?
Thanks.

Ventilation should be sized on people (cfm/person) and area (cfm/ft2). Also, you may be exhausting for industrial purposes? Washrooms?
I'd check the off HX temp on your HRV at design, drop it by 5 degrees then picture it dumping into the space. If that is acceptable, no reheat required.
