Abstract

An angled germicidal lamp is used to illuminate a coil and drain pan for optimum energy utilization. In one embodiment, a variable angled mount is used for positioning a germicidal lamp at a desired angle at the time of installation. In a second embodiment, a fixed angled mount is used for installation where the desired angle of mounting is known prior to installation. The angled germicidal lamp may be used with any coil installation, including flat, tilted and A-coils. For A-coil installations, a preformed delta plate is provided to ease installation.

Claims

1. An air conditioning system, comprising

a rectangular heat exchanger disposed within a duct having four sidewalls in a rectangular configuration,

a drain pan beneath said heat exchanger to collect condensation from said heat exchanger, and

a substantially linear germicidal tube for emitting energy to said heat exchanger and said drain pan, said germicidal tube disposed diagonally between first and second corners of said heat exchanger, wherein said first and second corners are opposite one another.

2. The air conditioning system of claim 1 wherein said heat exchanger comprises a slab coil.

3. The air conditioning system of claim 1 wherein said heat exchanger comprises an A-coil.

4. The air conditioning system of claim 1 and further comprising a mount for mounting said germicidal tube at a desired angle relative to one of said sidewalls of said duct.

5. The air conditioning system of claim 4 wherein said mount may be set at a selected one of a plurality of angles.

6. The air conditioning system of claim 4 wherein said germicidal tube is set within a range of ten to eighty degrees relative to said one sidewall.

7. An air conditioning system, comprising

a duct,

a heat exchanger disposed in said duct,

a drain pan beneath said heat exchanger to collect condensation from said heat exchanger, and

a substantially linear germicidal tube for emitting energy to said heat exchanger and said drain pan, said germicidal tube oriented at an angle between ten and eighty degrees relative to a plane of a sidewall of said duct.

8. The air conditioning system of claim 7 wherein said angle of said germicidal tube is approximately the same as the angle between opposite corners of said heat exchanger.

9. The air conditioning system of claim 7 wherein said angle of said germicidal tube is approximately the same as the angle between the profile of opposite corners of said heat exchanger projected onto a plane perpendicular to a major axis of said duct.

10. The air conditioning system of claim 7 wherein said angle of said germicidal tube is approximately the same as the angle between the profile of opposite corners of said heat exchanger a plane parallel to a major axis of said duct and a sidewall of said duct.

11. A germicidal lamp for controlling the presence of microorganisms on a heat exchange system, comprising:

a germicidal lamp for emitting radiation on said heat exchange system; and

a variable mounting system for mounting said germicidal lamp at one of a plurality of angles relative to a mounting surface, wherein said plurality of angles include at least one angle in the range of ten to eighty degrees.

12. The germicidal lamp of claim 11 wherein said mounting system includes a plurality of mounting couplers each having top and bottom surfaces at different angles such that one of said mounting couplers may be used to orient the germicidal lamp at a desired angle.

13. The germicidal lamp of claim 12 wherein said mounting system includes a flange on the base of the germicidal lamp that may be oriented at a variety of angles.
