House – 2 story, no basement, 2000 sq feet, 4 bedroom, 2.5 bath, Ductless heat pumps, ACH 1.9, Climate zone 6
I am in the process of planning my HRV retrofit. I have obtained a duct design from a local company and am in the process of getting the equipment so i can install the ductwork and HRV. I just wanted to ask the local community if they feel the design, airflow and equipment suggested make sense before moving ahead and purchasing.
Design airflow 138cfm high, 69 cfm low (I think it was calculated at 0.6 in w.c)
Recommended Equipment – Lifebreath 205 – 179 cfm @ 0.4, 148cfm @ 0.6
Could I use a Vannee 90H-V ECM instead of the recommended lifebreath – 80-157 cfm @ 0.4, 136CFM @ 0.6.
Attached are a few screen grabs from the report that was provided.
Thanks for your thoughts/input
