P-Factory Installed-Hot Gas Reheat (optional)
General
Hot Gas Reheat units provide a dehumidifying mode of op
eration. These units contain a reheat coil adjacent to and
downstream of the evaporator coil. Reheat coil solenoid
valve, L14, routes hot discharge gas from the compressor
to the reheat coil. Return air pulled across the evaporator
coil is cooled and dehumidified; the reheat coil adds heat to
supply air. See figure 48 for reheat refrigerant routing and
figure 49 for standard cooling refrigerant routing.
