- 2. a first fan mounted to the inside of the wrap adjacent to a first one of the ends, the fan being ducted for exhausting air from within the wrap, and
- 3. a second fan mounted to the inside of the wrap adjacent to the second end, the second fan being ducted for blowing air from within the wrap out the back of the wrap and into an inlet in the enclosure wall;
- b. a refrigeration chassis having
- 1. a frame having first and second legs forming an L-shape,
- 2. an operable refrigeration system mounted on the frame with a compressor and a condenser coil mounted on a first side of the L-shaped frame and an evaporator coil mounted on a second side of the L-shaped frame,
- 3. the chassis being mounted in the wrap with a first leg of the L-shaped frame being adjacent and parallel to the back and the second leg extending between the wrap front and the back, the frame being attached to each side of the wrap and dviding the wrap into first and second chambers with the compressor, condenser coil and first fan being in the first chamber and the evaporator coil and second fan being in the second chamber;
- c. a baffle positioned between the evaporator coil and the wrap back and baffling the second chamber into an air inlet from the wrap back to the evaporator coil and into an air outlet from the evaporator coil to the second fan;
- d. an air inlet to the first chamber;
- and
- e. a cabinet front cover removably fastened to the wrap and forming in the first chamber a path of air flow from the inlet through the condenser coil and then to the first fan, and also closing the front of the second chamber.

An air conditioner for attachment to the exterior wall of an enclosure box for controlling the temperature within the enclosure box, comprising:
- a. a cabinet having panels forming a box having a back side with means for mounting of the air conditioner to the wall of an enclosure box:
- b. an operative refrigeration system within the cabinet;
- c. air ducting in the back side of the cabinet for drawing hot air from the enclosure to an evaporator coil and blowing cold air from the coil into the enclosure;
- d. an air inlet and an air outlet in and through the cabinet panels for intake of ambient air to a condenser coil and exhaust of heated air from the condenser coil to ambient;
- and
- e. an air filter holder mounted on the cabinet and having a pair of filter retainers, a first retainer being adjacent an edge of the air inlet and a second retainer being on the opposite side of the air inlet and spaced from the first retainer a distance of twice the size of the air inlet as measured between the retainers, for retaining an air filter to the cabinet with one half of the filter covering over the air inlet, the retainers being able to identically retain the air filter when the filter is turned end for end so that the filter may be used twice before replacement thereof.
