Reverse air cycle air conditioner

An air conditioning apparatus comprising:

• a housing;
• a first partition disposed within the housing to define in conjunction therewith a condenser plenum, said first partition containing a first partition window;
• a condenser housed within the condenser plenum and dividing the condenser into inlet and outlet chambers, each chamber being in communication with a portion of the first partition window;
• a second partition disposed within the housing, separate and substantially parallel to the first partition, to define an evaporator plenum;
• said second partition containing a second partition window;
• an evaporator housed within the evaporator plenum that divides the evaporator plenum into inlet and outlet chambers, each chamber being in communication with a portion of the second partition window;
• a third partition within the housing, in a plane transverse to the first and second partitions, that divides the space between the first and second partitions;
• a single damper carried sealingly between the first and second partitions, having two co-acting portions, one on either side of and sealingly engaging the third partition;
• said damper being pivotal about an axis transverse to the third partition to at least one of heat and cool positions;
• an indoor compartment defined by the space between the first and second partitions, the damper and the housing;
• said indoor compartment having discharge and suction chambers defined by the third partition therebetween;
• said indoor compartment being operable to be placed exclusively in communication through at least one of the first partition window with the condenser plenum, and the second partition window with the evaporator plenum, as the damper is in respective heat and cool positions;
• means for flowing air through the discharge chamber of the indoor compartment and in heat exchange relationship with at least one of the condenser and the evaporator;
• an outdoor compartment on the opposite side of the damper from the indoor chamber, defined by the space between the first and second partitions, the damper, and the housing;
• said outdoor compartment having discharge and suction chambers defined by the third partition therebetween;
• said outdoor compartment being operable to be placed exclusively in communication through at least one of the first partition window with the condenser plenum, and the second partition window with the evaporator plenum, as the damper is in respective cool and heat positions;
• and
• means for flowing air through the discharge compartment of the outdoor chamber and in heat exchange relationship with at least one of the evaporator and the condenser.
