If you’re considering hiring licensed professionals to install custom louvers on your property, you might have a few questions about them. For custom louvers, form and function typically go hand in hand. For louvers, it’s a relatively attractive way to cover up the exterior wall opening required for the murky air intake and exhaust of an HVAC system. Custom louvers also do an excellent job providing privacy and keep water, wind, and intruders out of your property. Here are a few pointers on how contractors decide precisely how to size and install custom louver for your property’s HVAC system.
The Cut for Your Custom Louvers
The entire process of determining proper custom louver sizing should precede the cut into the outside wall. If the louver doesn’t align perfectly with the back of the HVAC system, a rear extension can be used to assist in fitting the unit. The hole should be sized to ensure a close enough fit to prevent any water from intruding.
The open, or free area, is defined as space through which both fresh and discharged air will flow throughout the custom louver. It is the space that isn’t occupied by any louver blades. This will account for about 35 to 60 percent of the total louver space. A supplier will generally provide a chart specifying the amount of free space needed to provide fresh air to the specified unit.
Intake vs. Exhaust Split
The split wall sleeve behind the custom louver separates fresh air from any exhaust air. The splits are then set at a slight angle to shed off moisture and are based on the preferred percentage of intake to exhaust. For example, 55 (intake percent to 45 (exhaust) percent. The required split is determined by the needs of individual units and can be determined using calculated formulas.
Free Area Velocity
This is just the flow rate of air divided by the cross-sectional area that it moves through.
Rated Water Penetration Velocity
This is the intake speed at which your HVAC unit will begin to draw water through the custom louver. This is a vital value because it sets the threshold at which a custom louver can allow any damaging water into your property and your HVAC system. This value is normally provided in the catalog that is accompanied by your custom louver.
