Description
- The present invention relates generally to ventilation systems and methods and more specifically to ventilation systems and methods that utilize integrated duct assemblies.
- Adequate ventilation is necessary for the comfort and safety of building occupants. Ventilation involves air exchange between interior and exterior of a building as well as air circulation within the building. It is a crucial factor and is subject to an important minimum legal requirement. Methods for ventilating a building may be divided into mechanical/forced and natural types.
- Many mechanical type systems use some form of direct venting that provide direct access between the inside and the exterior of a building. While such ventilation systems facilitate air exchange, rodents or other pests can get past or through them into the building structure. Such ventilation systems also suffer from penetration of moisture into the building structure.
- Moisture penetration is another issue associated with mechanical type systems. Such ventilation systems can allow moisture into building causing structural damage as well as mold, mildew or other such hazardous health conditions. In addition, such ventilation systems often require more space than is available in the exterior wall of a building structure.
- It is within the aforementioned context that a need for the present invention has arisen. Thus, there is a need to address one or more of the foregoing disadvantages of conventional systems and methods, and the present invention meets this need.
- Various aspects of a multi-tap integrated duct assembly apparatus and method can be found in exemplary embodiments of the present invention.

Each blade is spaced equally spaced apart and angled downward.
- The unitary integrated duct assembly further includes a plenum box having a front, a rear, and a base. The base is angled such that it slants downward from the rear to the front, wherein the plenum box is physically coupled at the front to the louver. Air flows from an external environment to an internal environment through the louver. Moisture is removed from the internal environment to the external environment through the weep holes of the plenum box.
- In one embodiment, a plurality of taps or inlet members that are coupled to an intake end of the plenum box enable passage of air flow from an internal environment to an external environment through the blades of the plenum box. In this manner, additional ducts can be coupled to the inlet members with only a single plenum box. At least one divider segregates the air flow passing from the inlet members through the plenum box.
- In a further embodiment, a method includes providing a louver having multiple blades from a bottom of the louver to a top of the louver, the multiple blades spaced equally apart and angled downward, the louver also including multiple weep holes at the bottom; the method providing a plenum box with an exhaust end, an intake end, and a base. The plenum box is connected at the exhaust end to the louver, where the base is angled such that it slants downward from the intake end to the exhaust end, the moisture is removed from the plenum box through the weep holes; the method uses multiple taps or inlet members coupled to the intake end of the plenum box, to pass air flow from an internal environment to an external environment through the blades of the louver; and the method installing the inlet members as a singular unit with the plenum box.
- In a further embodiment, the method includes providing at least one divider extending between the intake end and the exhaust end of the plenum box, the at least one divider segregating the air flow passing through the plurality of inlet members.
- An advantage of the unitary multi-tap integrated duct assembly of the present invention is that it is easily installed as a singular unit into congested and size limited exterior walls of a building structure. The unitary multi-tap integrated duct assembly also includes a weather tight seal with the building structure.

Although not shown, one of ordinary skill in the art will realize thatlouver 101 may be any shape or configuration consistent with the spirit and scope of the present invention. - In
FIG. 1 , unitary integratedduct apparatus 100 further includes a J-moldedframe 102 protruding from an outside oflouver 101, the J-molded frame havingweep holes 103 at its own bottom face. An advantage of the present invention is that weepholes 103 enable shedding of water that is driven into the unitaryintegrated duct apparatus 100 from external wind and/or rain. Although shedding of moisture is accomplished via weepholes 103, a person skilled in the art will realize that said shedding of moisture can be implemented via other means consistent with the spirit and scope of the present invention. - In
FIG. 1 ,plenum box 105 is positioned such that it slants toward weepingholes 103 to enable water driven into unitaryintegrated duct apparatus 100 to be discharged to the exterior of the building. It is evident by the above described assembly of unitaryintegrated duct apparatus 100, water can be removed from the inside ofplenum box 105 via weepholes 103 to the exterior of the building. Unlike conventional systems which retain water within the plenum box, causing mold and other unhealthy conditions, the present invention discharges entrained moisture to prevent unhealthy spore conditions as well as provide building stability. - Unitary
integrated duct apparatus 100 further provides improvements over conventional systems as a result of being a singular assembly. Conventional systems can require adaptation of an existing plenum box in order to attach a louver. - According to one embodiment, unitary
integrated duct apparatus 100 is two inches deep and can fit into an exterior wall with water tight application. The unitary integrated duct assembly of the present invention overcomes disadvantages faced by prior systems, including ineffective water tight seals. Such disadvantages are related to small sized louvers required due to space constraints and exterior wall thickness. In another embodiment, the unitary integrated duct assembly combines the space efficiency of smaller systems with the performance of larger systems. -
