Use this tool to help determine if your ductwork configuration will result in acceptable performance.
- Determine whether you need 50Hz or 60Hz equipment and select the appropriate category.
- You must calculate ductwork for the evaporator/fan coil and the condensing unit separately.
- ‘Duct length’ equals both the duct length to the farthest supply grill and to the farthest return grill from the unit.
- Supply grilles and return grilles are calculated using Wine Guardian grilles.
Note: This ductwork calculator should be used as a guide only. Variables in ductwork construction and system layout may affect static pressure loss and cooling unit performance, and as such Wine Guardian cannot guarantee system performance based solely on calculator results.
We reserve the right to make changes to this calculator at any time without prior notice.
