Multi-position air conditioning unit

Claim 2

An air conditioning unit adapted for installation in a vertical disposition and either of two horizontal dispositions comprising: a cabinet including front and rear faces and containing blower means for creating air flow through said cabinet in one direction, said cabinet being adapted to receive air therein through a front face inlet and alternatively an end inlet, said cabinet front face having access panel means separable from said cabinet; a fin and tube evaporator coil angularly disposed in said cabinet with its upstream face presented to both said front face inlet and said end inlet areas; a first condensate drain trough encompassing that end of said coil adjacent the front wall; a second condensate drain trough encompassing that end of said coil adjacent said rear wall; a drain pan of relatively large area extending along the rear wall of said cabinet and facing the downstream face of said coil and inclined relative to the rear wall fo feed condensate into said second drain trough; a detachable drip tray of relatively small area compared to said drain pan and facing the upstream face of said coil, and adapted to be positioned to feed condensate to said first drain trough in one horizontal position of said unit, and to feed condensate to said second drain trough in a vertical disposition of said unit.

Claim 3

An air conditioning unit according to claim 1 wherein: said first condensate drain trough includes a drain aperture therein in the portion of said trough facing the end inlet area; and said second condensate drain trough includes one drain aperture in the portion of the trough facing the end inlet area, and another drain aperture in the portion of the trough facing said front inlet area.

Claim 4

An air conditioning unit adapted for installation in a vertical disposition and either of two horizontal dispositions comprising: a cabinet including front and rear faces and containing blower means for creating air flow through said cabinet in one direction, said cabinet being adapted to receive air therein through a front face inlet and alternatively an end inlet, said cabinet front face having access panel means separable from said cabinet; a fin and tube evaporator coil angularly disposed in said cabinet with its upstream face presented to both said front face inlet and said end inlet areas; a first condensate drain trough encompassing that end of said coil adjacent the front wall and having a drain aperture therein in the portion of said trough facing said end inlet area; a second condensate drain trough and drain pan assembly including a trough portion encompassing that end of said coil adjacent said rear wall and a pan portion extending along the rear wall over an area upon which condensate would drop from said coil when said cabinet is disposed horizontally with the rear wall on the bottom, said drain trough having a drain aperture in both the portion of said trough facing said end inlet area and the portion facing said front inlet area; a detachable drip tray having one position on the upstream face side of said coil for feeding condensate to said second drain trough when said cabinet is in a vertical disposition, and having an alternative position on the upstream face side of said coil for feeding condensate to said first drain trough when said cabinet is in a horizontal disposition with said rear face on top; the relationships between said coil drain troughs, drain pan and drip tray accommodating the installation of said cabinet in a vertical disposition, and in a horizontal disposition with either said front or rear face on top.

Claim 5

An air conditioning unit adapted for installation in a vertical disposition and either of two horizontal dispositions comprising: a cabinet including front and rear faces and containing blower means for creating air flow through said cabinet in one direction, said cabinet being adapted to receive air therein through a front face inlet and alternatively an end inlet, said cabinet front face having access panel means separable from said cabinet; a fin and tube evaporator coil angularly disposed in said cabinet with its upstream face presented to both said front face inlet and said end inlet areas; a first condensate drain trough encompassing that end of said coil adjacent the front wall and having a drain aperture therein in the portion of said trough facing said end inlet area; a second condensate drain trough and drain pan assembly including a trough portion encompassing that end of said coil adjacent said rear wall and a pan portion extending along the rear wall over an area upon which condensate would drop from said coil when said cabinet is disposed horizontally with the rear wall on the bottom, said drain trough having a drain aperture in both the portion of said trough facing said end inlet area and the portion facing said front inlet area; a detachable drip tray having one position on the upstream face side of said coil for feeding condensate to said second drain trough when said cabinet is in a vertical disposition, and having an alternative position on the upstream face side of said coil for feeding condensate to said first drain trough when said cabinet is in a horizontal disposition with said rear face on top; the relationships between said coil drain troughs, drain pan and drip tray accommodating the installation of said cabinet in a vertical disposition, and in a horizontal disposition with either said front or rear face on top.
