Abstract:
A refrigeration system comprising:a supply air duct; an indoor heat exchange coil operably positioned in the supply air duct; a reheat heat exchange coil operably positioned in the supply air duct; an outdoor heat exchange coil; at least one compressor; an expansion device; refrigeration system tubing connected to and serially arranging the compressor, the outdoor heat exchange coil, the expansion device and the indoor coil into a refrigeration circuit; reheat tubing connecting the reheat coil to the refrigeration tubing so as to arrange the reheat coil in a parallel circuited arrangement with the outdoor heat exchange coil and in a series circuited arrangement with the compressor, the expansion device and the indoor heat exchange coil; and a subcooler located between and operably connected to the indoor heat exchange coil and the parallel circuited arrangement wherein the subcooler is located in the supply air duct in physical proximity to the reheat coil; further including a refrigerant receiver operably connected to the refrigeration system tubing between the subcooler and the parallel circuited arrangement and a control valve in the reheat tubing operable to control refrigerant flow through the reheat coil wherein the valve is controlled responsive to a supply air duct condition.
