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. Unit Enclosure: A 14-gauge galvanized base panel shall be incorporated in all units. The unit shall be a minimum of 18-gauge galvanized panels. Supports shall be constructed of 14-gauge galvanized steel. Removable panels shall be provided to allow easy access to all internal parts and components. The electrical control box and switch panel shall be enclosed in a separate compartment, complete with a hinged door. Single Side Service Access — The unit shall be designed for complete access for service and maintenance from one side only. The units will require side access for easy removal of the filters. See mechanical drawings for access required. CEA#18010 100% OUTSIDE AIR UNITS 23 75 33 -2 COPYRIGHT©2018 CONSULTING ENGINEERING ASSOCIATES, INC.
