Abstract
A low profile evaporator coil assembly and method for configuring the assembly in HVAC equipment. In one deployment, the assembly 40 is located between a heating furnace and a plenum. The assembly 40 includes multiple coil slabs 42 through which a refrigerant courses. The slabs 42 lie in a parallel relationship at an angle of inclination to the air entering a coil assembly 40. A baffle 46 is associated with each coil slab 42 to constrain air flow through the associated coil slab. A drain pan 52 is positioned beneath the slabs. The drain pan 52 has multiple troughs 54 for collecting condensate. At least some of the multiple troughs 54 have an air foil 56 that reduces air flow restriction.
Claims12
A low profile evaporator coil assembly for use in heating, ventilation and air conditioning equipment, the assembly being located proximal to a discharge side of a heating furnace or the inlet side of an air handler and upstream of a plenum, the assembly comprising:
- multiple coil slabs, each slab having coil segments that define an internal passage therewithin, said passage being adapted for a refrigerant flow therethrough, the multiple coil slabs having an angle of inclination to a major component of air entering the multiple coil slabs;
- and
- a baffle associated with each coil slab of the multiple coil slabs for directing air through a corresponding one of the multiple coil slabs, the baffle associated with each coil slab being positioned around opposed ends of the corresponding one of the multiple coil slabs, the baffle associated with each coil slab being configured to direct substantially all of the air that contacts the baffle through the corresponding one of the multiple coil slabs.
A method for configuring an evaporator coil so that its performance characteristics meet or exceed minimum SEER requirements and yet can be accommodated within spatial constraints, the method comprising the steps of:
- deploying a multiple slab coil assembly through which a refrigerant is able to course, each slab in the multiple slab coil assembly having an angle of inclination to the air entering the multiple slab coil assembly;
- mounting a baffle around each slab coil, each baffle being configured to constrain air contacting the baffle to flow only through an associated coil slab;
- and
- locating a drain pan beneath the multiple coil slab assembly, the drain pan being provided with multiple troughs for collecting condensate and with an air foil that reduces air flow restriction by directing incoming air in a divergent pattern toward adjacent slabs.
