Geothermal heat pump system having a downflow appliance cabinet

Abstract

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.

1 . A down-flow appliance cabinet for indirect-exchange heat pump systems comprises:
 a generally rectangular cabinet structure having
 a rear panel; 
 right and left front corner posts; 
 a top cover having an air intake opening; 
 a bottom cover having a conditioned air exit; 
 a central shelf having a central aperture incorporating a fan mount; 
 an air duct coupling the conditioned air exit and the central aperture; 
 a radiator frame diagonally positioned above the central shelf; 
 an upper coil mount secured to the rear panel above the central shelf; 
 a lower coil mount secured to the rear panel below the central shelf; 
 a compressor base secured to the bottom cover; and 
   a plurality of covers to fully enclose the front and sides of the cabinet structure.   
     
     
         2 . The down-flow appliance cabinet of  claim 1 , wherein said upper coil mount is intended to hold a refrigerant/ground loop heat exchanger mounted within the upper chamber beneath the radiator frame and said lower coil mount is intended to hold a desuperheater heat exchanger.
