Abstract
Disclosed is an improved ventilator comprising a turbine, and a fan configured to force air from a ventilated space, the fan being coupled to the turbine so that rotation of the turbine results in rotation of the fan at a rotational speed greater than that of the turbine.
Description
- The invention relates generally to roof ventilators and in particular to an enhanced wind-powered turbine roof ventilator.
- Wind-powered turbine ventilators are widely used in a variety of ventilation applications. Turbine ventilators are especially suited for ventilation of the under-roof space of residential, commercial, and industrial buildings. The popularity of wind-driven turbine ventilators derives from their relatively small initial costs, low maintenance requirements, and negligible operating costs.
- Turbine ventilators reduce the cost of cooling a building by removing hot air from the under-roof space of a building. Because the effectiveness of a ventilator is a function of the amount of air the ventilator is able to remove from the ventilated space, it is desirable to increase the volume of air-flow through a ventilator. It is further desirable to increase airflow without increasing the size of the ventilation assembly, because larger ventilators are more expensive to manufacture, generally considered unaesthetic, and may take up otherwise useful space.
- One solution found in the prior art is to use an externally-powered fan to force air through the ventilator. However, the use of an external power source inherently makes the ventilation apparatus more complicated to manufacture, and more prone to malfunction; translating into higher production and maintenance costs. Use of an external power source also makes the ventilator more expensive to operate than a wind-powered ventilator.
- Another solution attempted in the prior art involves including a fan within the ventilation apparatus and connecting the fan by a rod directly to the wind-powered turbine. However, because the rotational speed of the turbine is relatively slow, the fan does not turn quickly enough to provide a sufficient increase in airflow.
- The invention relates to an improved ventilation apparatus comprising a fan which is coupled to a turbine so that rotation of the turbine results in rotation of the fan at a greater speed of rotation than the turbine.
- For a more complete understanding of the present invention and the advantages thereof, reference is now made to the following description taken in conjunction with the accompanying drawings, in which:
- FIG. 1 illustrates a ventilation apparatus;
- FIG. 2 illustrates a gear assembly which may be used in a ventilation assembly;
- FIG. 3 depicts a turbine which may be used in a ventilation assembly; and
- FIG. 4 depicts a fan which may be used in a ventilation assembly.
- Referring to the drawings, FIG. 1 shows a wind-powered
turbine ventilator 100 embodying features of the present invention. In the embodiment shown in FIG. 1, theventilator 100 includes aturbine 12 rotably mounted on aventilation shaft 14, which extends from aventilation port 19 in aroof 16. Flashing 13 is preferably used between theventilation shaft 14 and theroof 16 to prevent precipitation from entering the building. Theturbine 12 is preferably mounted to theventilation shaft 14 using a plurality ofsupport members 15, which extend from the outer perimeter of theventilation shaft 14. Thesupport members 15 are preferably connected at the opposite end to a bearinghousing 17 at a point above the center of theturbine 12. The top of theturbine 12 is preferably rotably mounted in the bearinghousing 17 so that theturbine 12 is rotably supported above theventilation shaft 14 by thesupport members 15. A number of other methods of rotably mounting theturbine 12 above theventilation shaft 14 are known in the art, and any method may be used which is effective for holding theturbine 12 in position above theventilation shaft 14 while allowing rotational movement of theturbine 12. - A
fan 18 is positioned within or near theventilation shaft 14, preferably near theventilation port 19, and is preferably configured to force air from the ventilated space through theventilation port 19. Thefan 18 preferably is coupled to theturbine 12 so that rotation of theturbine 12 results in rotation of thefan 18. More preferably, thefan 18 is coupled to theturbine 12 so that rotation of theturbine 12 causes the fan to rotate at a greater speed of rotation than theturbine 12, preferably at a ratio of at least approximately 1.5:1, and, most preferably, at a ratio of about 15:1. Thefan 18 is preferably coupled to theturbine 12 so that thefan 18 rotates in the same direction as the turbine, but may alternatively be configured to rotate in the opposite direction. - Preferably, an
axle 20 is mounted to theturbine ceiling 22, preferably near its center. Theaxle 20 preferably extends downward from theturbine ceiling 22, substantially in alignment with the axis of rotation of theturbine 12. Theaxle 20 is preferably fixed in position with respect to theturbine 12, so that theaxle 20 rotates with theturbine 12. - Referring to FIG. 2, the opposite end of the
axle 20 is preferably configured to provide driving power to agear assembly 24. Thegear assembly 24 is preferably held in a fixed position relative to the ventilation shaft by one ormore braces 26. Theaxle 20 is preferably connected by acoupler 31 to aninput shaft 32, which preferably extends through a bearinghousing 34. Toward the opposite end of theinput shaft 32, afirst gear 36 is preferably mounted to theinput shaft 32. Thefirst gear 36 is preferably configured to drive asecond gear 38 mounted on agear shaft 40. Thegear shaft 40 is preferably rotably mounted in thegear assembly 24 housing. Athird gear 42 is preferably mounted on thegear shaft 40, so that thethird gear 42 turns in conjunction with thesecond gear 38. Thethird gear 42 is preferably configured to drive afourth gear 44, which is preferably mounted on an upper end of anoutput shaft 46. - Preferably, the circumference of the
first gear 36 is approximately 4 times the circumference of thesecond gear 38. The circumference of thesecond gear 38 is preferably about ¼ the circumference of thethird gear 42. The circumference of thethird gear 42 is preferably about 4 times the circumference of thefourth gear 44. However, any gear size ratios may be used that is effective for rotating thefan 18 at a greater speed of rotation than that of theturbine 12. - The
output shaft 46 preferably extends through a second bearinghousing 48 to thefan 18. Theoutput shaft 46 is preferably used to drive thefan 18 and to provide support for thefan 18. Alternatively, theoutput shaft 46 may be used only to provide a driving force to thefan 18, and thefan 18 may be supported by another method, such as by use of additional braces (not shown) and a bearing assembly (not shown). - Although the coupling mechanism shown in FIG. 2 and described above is the preferable coupling means, the
fan 18 may alternatively be coupled to theturbine 12 by other means. For example, a drive axle to the gear housing could be configured to engage a theturbine 12 at abottom rim 30, or theturbine 12 could be configured to drive a flywheel (not shown), which could in turn be used to drive a fan. Alternatively, theturbine 12 could be used to drive an electric generator (not shown), which could be used to generate electricity to drive an electric fan (not shown). In yet another embodiment, thefan 18 may be coupled to theturbine 12 by a hydraulic connection (not shown). In yet another embodiment, an external power source (not shown), such as solar power or commercially-available electricity, could be used in addition to wind power, to aid in ventilation when wind power is inadequate. Generally, any mechanism may be used for coupling thefan 18 to theturbine 12 that is effective for transferring energy from theturbine 12 to thefan 18 and for causing the fan to rotate at a greater rotational speed than theturbine 12. - FIG. 3 depicts a fan that may be used in a ventilator embodying aspects of the present invention. Preferably, the
fan 18 comprises a plurality offan blades 52 attached to afan hub 54. Preferably, thefan 18 has about fourfan blades 52, although any number offan blades 52 may be used. A hole 56 is preferably defined in thefan hub 54 and the hole 56 is preferably configured to receive anoutput shaft 46, as shown in FIG. 1. Many other fans, impellers, propellers, blowers, and the like are known in the prior art and may be used in the present invention. - FIG. 4 illustrates a turbine that may be used in a turbine ventilator. The
turbine 12 preferably comprises a plurality ofturbine blades 64, attached at an upper end to a roof 62 and attached at a lower end to arim 30. Theturbine blades 64 are preferably curved outward from the center of theturbine 12, and are preferably positioned at an angle with respect to the circumference of theturbine 12. Theturbine blades 64 are also preferably placed in close proximity to one another so that, in combination, the blades substantially prevent precipitation from entering theventilation shaft 14. Alternatively, a separate cover (not shown) may be place over theventilation shaft 14 to block precipitation, or precipitation may be allowed to enter theventilation shaft 14 and then directed into a drain (not shown). Other turbine designs are known in the prior art and may be used in the present invention. - Having thus described the present invention by reference to certain of its preferred embodiments, it is noted that the embodiments disclosed are illustrative rather than limiting in nature and that a wide range of variations, modifications, changes, and substitutions are contemplated in the foregoing disclosure and, in some instances, some features of the present invention may be employed without a corresponding use of the other features.
