Mixing an HRV and exhaust only for ventilation
I posted a couple weeks ago about how I am looking for a solution for venting my new home. It has two bedrooms that are on the second floor of a timber frame building. The master suite which has a basement below is situated in such a way that it is difficult or impossible to duct from the basement area up to the 2 bedrooms in the timber frame portion. This basically leaves me with using the lunos fans or 2 ducted hrv units. It looks like I need a bit less than 100 cfm of air exchange. So I am wondering if I could use the Panasonic intellebalance cold climate unit, setting it up for about 100 cfm on the supply ( ducting this supply into the great room , the central part of the house) then setting the hrv exhaust ( To 50 cfm )And to pull thru the master bedroom and exhaust from the master bath. On the second floor I would install a bath fan with exhaust only set to around 50 cfm also . As these bedrooms are above the great room it should provide decent mixing. I am in zone 5 . It seems this would provide a reasonably priced balance solution, any thoughts or comments would be appreciated .
