In the dehumidification process, latent heat is transferred from the outside air to the refrigerant as it passes through the evaporator coil. As the air is cooled below its dew- point, moisture condenses on the evaporator coil. The latent heat captured by this process, along with the power consumption of the compressor, is absorbed by the mechanical refrigeration system. This energy is returned to the air stream via the reheat coil, resulting in lower relative humidity of the leaving air. 2. The energy recovered is split between the hot gas reheat condenser and a full-size, outdoor air-cooled condenser or optional water condenser. Hot gas reheat is varied automatically by a modulating valve controlled by a microprocessor controller, so that the user's system leaving air temperature set-point is maintained to within + or — 2.0° F. During the heating season, the compressor shall be locked out below a 550 F entering air dew point. When the unit is provided with a full cooling option, on a call for cooling from an optional space thermostat, the unit will disengage the hot gas reheat. B. Unit Description 1.
