This table lists the cooling CFM for each CellarPro cooling unit (at each fan setting, if applicable). To size an evacuation fan using these CFMs, be sure to adjust for pressure losses based on the fan curve of the evacuation fan.

Air Changes per Hour

It is calculated based on the cellar size (at sea level, assuming R19 insulation, 85° F ambient temperature and 55° F cellar temperature). Air Changes per Hour is a useful metric for comparing cooling units and optimizing for a given application. Less than 10 or greater than 30 are not recommended, to avoid short cycling. The higher the value within this range, the better a unit is able to manage heat load changes, such as opening a door or re-stocking the wine cellar.
