Abstract
A ceiling mounted apparatus draws air upwardly through an inlet and processes the air through heat exchange elements before distributing the air downwardly. The air is preferably distributed downwardly by air discharge structure surrounding the heat exchange elements. The air is ultimately discharged through one or more air discharge ducts positioned relatively close to the air inlet. Each air discharge duct includes a rotatable louver mounted therein that in conjunction with the walls of the duct defines particular paths for the conditioned air in heating versus cooling.
Claims15
Ceiling mountable apparatus for heating or cooling air, said apparatus comprising:
- an external housing;
- a frame containing an air inlet, said frame fitting into said external housing;
- a fan within the external housing for drawing air up through the air inlet in said frame and for subsequently distributing the drawn in air radially outwardly;
- a plurality of heat exchange elements positioned radially outwardly of said fan for heating or cooling the radially distributed air from said fan;
- air channel structure positioned within the external housing relative to said fan so as to deflect the radially distributed air from said fan downwardly;
- and
- at least one air discharge duct in said frame containing the air inlet, said discharge duct having a first wall located near at least one edge of the air inlet and a second wall opposite said first wall which is located further outwardly from the edge of the air inlet than said first wall, wherein said first and second walls are smooth, continuous walls formed in said frame wherein said first wall in said discharge duct comprises a first straight wall portion followed by a curved wall portion followed by a second straight wall portion terminating where air is discharged from the discharge duct, said second straight wall portion being at an angle relative to said first straight wall portion so as to direct air discharged from the discharge duct away from the air inlet.
