Abstract: An air system includes an enclosure including walls; and selectively removable opening sections on one or more of the walls. Each of the selectively removable opening sections comprises a part that is selectively removable to create an air flow passageway out of the enclosure. The air system and/or enclosure is thus adaptable for different configurations of air flow.

Abstract: An air treatment system having an outer heat exchange coil, an inner heat exchange coil spaced-apart from and encompassed by the outer heat exchange coil, seal structure positioned with respect to both coils so that air pulled through the air treatment system by air movement apparatus may flow through the inner heat exchange coil without flowing through the outer heat exchange coil; and in one aspect, an air treatment system having an outer heat exchange coil; an inner heat exchange coil within the outer heat exchange coil; the inner coil spaced-apart from the outer heat exchange coil; the inner heat exchange coil and the outer heat exchange coil defining an inner chamber therebetween; the inner chamber positioned so that air exhaust apparatus above the inner heat exchange coil moves air into the inner chamber for exhausting therefrom by the air exhaust apparatus; air flowing from outside the outer heat exchange coil, through the outer heat exchange coil, and into the inner chamber; and air flowing from outsi

Abstract: An air conditioning coil system having a first and a second outside tubing slab, a first and a second inside tubing slab, the inside tubing slabs positioned between the outside tubing slabs, a top of the first outside tubing slab contacting a top of the first inside tubing slab, a top of the second outside tubing slab contacting a top of the second inside tubing slab, and a bottom of the first inside tubing slab contacting a bottom of the second inside tubing slab, each tubing slab having a plurality of spaced-apart heat exchange fins, each outside tubing slab having a plurality of spaced-apart tubing rows extending through he plurality of heat exchange fins of the corresponding outside tubing slab, and each inside tubing slab having at least one tubing row extending through the plurality of heat exchange fins of the corresponding inside tubing slab.

Abstract: A multi-pan for an air conditioning system which has a coil positionable in one of three orientations has been invented, the multi-pan includes, in certain aspects, a bottom pan having walls defining an inner space the bottom pan disposed for receiving water from the coil when the coil is positioned above the bottom pan, a first side pan connected at one end to the bottom pan, the first side pan disposed for receiving water from the coil when the coil is positioned above the first side pan, and a second side pan connected at one end to the bottom pan and spaced apart from the first side pan by the bottom pan, the second side pan disposed for receiving water from the coil when the coil is positioned above the second side pan. the bottom pan can be configured for an A (or V) coil with an air flow space therethrough, or for an M-coil with two air flow spaces therethrough and a middle pan part.

Abstract: An insulator has been invented for use between adjacent portions of wire coils of a helical heater wire, the insulator, in one aspect, having a body member with a front, a rear, a first side, a second side, a top, and a bottom, a first groove formed in the front of the body member and extending from the first side to the second side, the first groove for receiving and holding a first portion of a first wire coil. In certain aspects the insulator also has a second groove formed in the rear of the body member spaced apart from the opposite the first groove, the second groove extending from the first side to the second side, the second groove for receiving and holding a portion of a second wire coil adjacent to and spaced apart from the first wire coil. In one aspect the first and second grooves are at a top of the body member and another pair of such grooves are at the bottom of the body member. A heater element has been invented with such an insulator and a heater has been developed with such a heater element.

Abstract: A drain pan system has been invented for receiving water condensed on and flowing from an air conditioning coil, including a pan with a pan member for receiving and holding water from the coil, and the pan member having a side lip for connecting to an adjacent pan, the adjacent pan adjacent the coil and disposed at an angle to the pan member. In one aspect the drain pan is used with the coil which is generally configured in a V-shape when viewed from an end thereof. In one aspect the system includes a lateral pan or pans sealingly connectible to the adjacent pan and to which the pan member is sealingly secured.

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.

Abstract: Air conditioning apparatus with an enclosure which both houses a conditioning coil and serves as a plenum for transferring air to one or more conduits. In one aspect, vanes of the coil or coils are oriented to direct air toward openings in the plenum. An enclosure that serves as a coil housing and as a plenum.

Abstract: An air distributor for mounting in a duct outlet in an air conditioning heating and ventilation system is provided to direct the flow of air within the conditioned space. A frame is mounted within the conditioned space and in fluid communication with the outlet of the duct. The frame has an opening therethrough. A deflection member is movably mounted to the frame from an open position wherein the air can flow into the conditioned space to a closed position where essentially no air flows into the conditioned space. The deflection member is selectively adjustable in intermediate positions between the open and closed positions. A diverter is provided with the deflection member and is accessible for adjustment from the conditioned space to selectively direct the air flow between the frame and deflection member into the conditioned space in a two way, three way and four way pattern.

Abstract: Disclosed is a plenum starter piece useful for attaching conduit to a planar plenum. The starter piece includes a body member which is a relatively short cylindrical piece having an external flange adapted to fit against the surface of the plenum and to accommodate fastening means. The outer end of the body member is proportioned for telescoping engagement with a conduit. Telescoped into the flanged end of the body member is an insert having a projecting end which is proportioned to fit through and engage the edges of a hole cut in the plenum.
