    摘要： A solid-state control for a variable air volume (VAV) temperature conditioning system adapted to control a plurality of refrigerant cooling stages, and in particular, to modulate an outdoor air economizer. The control includes both an outdoor ambient air and a discharge air temperature sensor. Further included are means for selectively modulating the economizer either in response to the deviation of the discharge air temperature from a setpoint or in response to the discharge air temperature, depending upon the relative magnitudes of the outdoor and discharge air temperature, and upon one or more stages of cooling being energized.

    摘要： A refrigeration system with a high percentage of fresh air. The system comprises 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; and an expansion device. The system also comprises 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; and 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. The system further comprises a subcooler located between and operably connected to the indoor heat exchange coil and the parallel circuited arrangement; and a control valve in the reheat tubing operable to control refrigerant flow through the reheat coil.
