Abstract
Abstract A drain pan with an opening or openings through which air flows to a coil and a coil which, in one embodiment, has a cover plate so air flowing through a drain pan flows between vanes of a coil rather than out from an opening at an end of the coil; such a pan in combination with such a coil; and a system with such a coil-pan combination which uses a single pan for multiple orientations of the coil-pan combination in both horizontal flow, up-flow, and down-flow systems.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
233 words
A device for conditioning air, the device comprising an enclosure having an interior and the enclosure having sides made of an insulative material and having a top metal member and a bottom metal member over the insulative material and an air conditioning coil with a plurality of vanes disposed in the enclosure, a first opening in the enclosure through which unconditioned air flows to the coil, air conducting means connected to the enclosure for conducting conditioned air from the enclosure, the air-conducting means comprising a plurality of at least two air-conducting conduits, at least two second openings in the enclosure to which flows air conditioned by the coil and from which air flows to the air-conducting means, one second opening corresponding to each of the at least two air-conducting conduits, the air flowing only once through the coil, the coil's vanes directing air in the general direction of the at least two second openings, a customizable connection member for connecting the first opening to an outlet of an air-conveying apparatus which conducts the unconditioned air to the first opening, the connection member comprising metal bracing members movably positionable about and securable about the first opening for accommodating the outlet of the air-conveying apparatus, a blower for moving unconditioned air to the first opening of the enclosure, the blower mounted adjacent to the air-conveying apparatus which conducts the unconditioned air to the second openings.
Claim 2
Independent Claim
233 words
A device for conditioning air, the device comprising an enclosure having an interior and the enclosure having sides made of an insulative material and having a top metal member and a bottom metal member over the insulative material and an air conditioning coil with a plurality of vanes disposed in the enclosure, a first opening in the enclosure through which unconditioned air flows to the coil, air conducting means connected to the enclosure for conducting conditioned air from the enclosure, the air-conducting means comprising a plurality of at least two air-conducting conduits, at least two second openings in the enclosure to which flows air conditioned by the coil and from which air flows to the air-conducting means, one second opening corresponding to each of the at least two air-conducting conduits, the air flowing only once through the coil, the coil's vanes directing air in the general direction of the at least two second openings, a customizable connection member for connecting the first opening to an outlet of an air-conveying apparatus which conducts the unconditioned air to the first opening, the connection member comprising metal bracing members movably positionable about and securable about the first opening for accommodating the outlet of the air-conveying apparatus, a blower for moving unconditioned air to the first opening of the enclosure, the blower mounted adjacent to the air-conveying apparatus which conducts the unconditioned air to the second openings.
Claim 3
Dependent Claim
28 words
The device for conditioning air of claim 1 wherein the enclosure has at least one side made from duct board suitable for easily cutting the second openings therethrough.
Claim 4
Dependent Claim
12 words
The device of claim 1 wherein the coil is a coiling coil.
Claim 5
Dependent Claim
67 words
The device of claim 1 comprising also a drain pan comprising a body member defined by side walls and at least one bottom wall, the bottom wall having a pan opening there-through for air flow to the coil, the coil mounted on the pan and having a general shape viewed from one end, and the pan opening corresponding in shape to the general shape of the coil.
Claim 6
Dependent Claim
27 words
The device of claim 4 wherein the general shape of the coil is a V-shape and the corresponding shape of the pan opening is a general V-shape.
Claim 7
Dependent Claim
51 words
The device of claim 4 wherein the at least one bottom wall is a plurality of bottom walls and the side walls and bottom walls define a plurality of sub-pans mounted to the body member, the sub-pans spaced apart by sub-openings so that air to be conditioned flows between the sub-pans.
Claim 8
Dependent Claim
92 words
The device of claim 4 wherein the coil is comprised of sub-coils which are generally configured in an M-shape when viewed from a side thereof, the coil having three bases comprised of extending edges of sub-coils, the pan having an end trough, the plurality of sub-pans comprising three sub-pans, one sub-pan extending adjacent and beneath each of the three bases of the coil, the three sub-pans communicating with the end trough, so that water flowing into the sub-pans flows into the end trough, and the end trough having a water drain outlet.
Claim 9
Dependent Claim
153 words
An air conditioning system drain pan comprising a body member defined by side walls and a plurality of bottom walls, the bottom walls for supporting a coil mounted on the drain pan, the coil comprised of sub-coils which are generally configured in an M-shape when viewed from a side thereof, the coil having three bases comprised of extending edges of sub-coils, the pan having an end trough, the plurality of bottom walls and the side walls defining a plurality of sub-pans mounted to the body member, the sub-pans spaced apart so that air to be conditioned flows between the sub-pans to the coil, the plurality of sub-pans comprising three sub-pans, one sub-pan extending adjacent and beneath each of the three bases of the coil, the three sub-pans communicating with the end trough, so that water flowing into the sub-pans flows into the end trough, and the end trough having a water drain outlet.
Claim 10
Dependent Claim
153 words
An air conditioning system drain pan comprising a body member defined by side walls and a plurality of bottom walls, the bottom walls for supporting a coil mounted on the drain pan, the coil comprised of sub-coils which are generally configured in an M-shape when viewed from a side thereof, the coil having three bases comprised of extending edges of sub-coils, the pan having an end trough, the plurality of bottom walls and the side walls defining a plurality of sub-pans mounted to the body member, the sub-pans spaced apart so that air to be conditioned flows between the sub-pans to the coil, the plurality of sub-pans comprising three sub-pans, one sub-pan extending adjacent and beneath each of the three bases of the coil, the three sub-pans communicating with the end trough, so that water flowing into the sub-pans flows into the end trough, and the end trough having a water drain outlet.
