1.Ventilation Needs A. Room count calculation Determine your ventilation needs installation How much fresh air do I need? Good air quality is based in part on the capacity of the home’s ventilation system. Usually, the HRV’s or ERVs capacity is measured in CFM (cubic feet per minute) or L/s (Liters per seconds) of fresh air being distributed in the living space. The room count calculation or the air change per hour method shows you how to determine your ventilation needs.
INSTALLATION GUIDE 2. Types of Installation (continued) Exhaust at the source and supply in the return There are different practices used to combine HRV or ERV to a forced air system. Exhaust at the source installation This application uses a devoted duct system for the exhausting of stale air accumulated in the home. The fresh air is dumped into the return air duct and is distributed thru the home by the existing supply air ductwork of the forced air system.
2. Types of installation (continued) Exhaust and supply in the return Exhaust and supply in the return 3’ installation When using this application make sure that there is at least 6' between the fresh air and exhaust air connections of the HRV or ERV in the return air duct. 6’ 6’ 18” Supply air from HRV or ERV must be at least 3' from the forced air system.
