This disclosure presents a heat exchanger that comprises a header frame having end plates, a plurality of rows of finned hairpins, each extending through a cooling fin and each having ends extending through the end plates, and at least one finless hairpin having ends extending through the end plates. Additionally, a support sheet is coupled to the header frame and at least on finless hairpin extends through the support sheet and is supported thereby. A method of manufacturing the heat exchanger is also presented as well as a heat ventilation air conditioning system in which the heat exchanger may be employed.

An apparatus for draining condensate accumulated by an air handling unit element, the element presenting a footprint area, includes: a substantially unitary plurality of surfaces oriented between a first level and a second level and bounded by a peripheral wall. The first level is generally higher than the second level in an installed orientation. A first surface is situated substantially at the first level and is generally horizontal and presents a generally planar expanse generally coextensive with the footprint area in the installed orientation. A second surface generally extends from the second level at a first end of the apparatus to the first level at two loci separated by the first surface at a second end of the apparatus opposite the first end to orient the first surface in a generally nested relationship with respect to the second surface. At least one third surface joins the first and second surfaces.

Apparatus and method for draining condensate

A low profile evaporator coil assembly and method for configuring the assembly in HVAC equipment. In one deployment, the assemblyis located between a heating furnace and a plenum. The assemblyincludes multiple coil slabsthrough which a refrigerant courses. The slabslie in a parallel relationship at an angle of inclination to the air entering a coil assembly. A baffleis associated with each coil slabto constrain air flow through the associated coil slab. A drain panis positioned beneath the slabs. The drain panhas multiple troughsfor collecting condensate. At least some of the multiple troughshave an air foilthat reduces air flow restriction.

Low profile evaporator coil

A drain pan for capturing condensate from a cooling coil in an air conditioning system is configured to facilitate condensate drainage from the pan and to inhibit accumulation of condensate therein. The pan includes troughs for collecting condensate and for channeling the condensate to the front part of the pan where the drain openings are located. A back trough has a central hump to enhance the flow of condensate from the back trough in both directions into opposed side troughs. The side troughs are sloped from back to front to conduct the condensate into a front trough to facilitate drainage from the pan. The lowermost portion of the front trough region is defined by a relatively narrow, non-flat area to reduce the amount of condensate residue in the pan.
