Unitized air conditioning apparatus for conditioning air for an enclosed space may include: an inlet chamber through which air may be drawn; first and second selectively operable air handling units by which air may be drawn through the inlet chamber and refrigeration apparatus for circulating refrigerant through the air handling units for heat exchange with air prior to discharge into the enclosed space. Air dampers are provided for isolating one of the air handling units, when not operating, from the other air handling unit when it is operating.

Unitized air conditioning apparatus for conditioning air for an enclosed space, said apparatus comprising: an inlet air chamber through which air may be drawn; first and second selectively operable air handling units by which air may be drawn through said inlet air chamber for subsequent discharge into said enclosed space; refrigeration means for circulating refrigerant through said air handling units for heat exchange with said air prior to its discharge into said enclosed space; and a common air chamber between said air handling units through which air passes from said inlet air chamber to either one of said air handling units, said common air chamber being provided with first and second isolation dampers through which said air must pass into said first and second air handling units, respectively, prior to said discharge into said enclosed space, each of said isolation dampers being selectively moveable between open positions, in which air is drawn through its respective air handling unit, and closed positions, in which air flow is blocked from its respective air handling unit.
