A compact, down-flow appliance cabinet for indirect-exchange heat pump systems has a bottom panel that incorporates a mounting plate for the compressor and a lower rectangular aperture for the exit of conditioned air. A center shelf parallel to the bottom platform divides the cabinet into upper and lower chambers and provides a mounting location for a blower assembly within the upper chamber on top of a middle aperture. An air duct interconnects the middle and lower rectangular apertures. A top cover incorporates an air filter mount and an upper rectangular aperture that couples to the return air duct. Diagonally-positioned radiator mounts, which are secured to the cabinet frame, provide a mounting location for the evaporator coil. A desuperheater heat exchanger mounts within the lower chamber adjacent the heat pump; a refrigerant/ground loop heat exchanger mounts within the upper chamber beneath the radiator mounts.
