Abstract
A humidity controller for an air handling unit of a space, room or zone. The controller may be a dehumidification system integrated with a constant volume air handling unit. The system may have separate actuator control of a mixed air damper and other actuator control for both an outdoor air intake damper and an indoor air exhaust damper. Humidity and temperature sensors may be placed outdoors and indoors in the space having air to be dehumidified, temperature controlled and/or mixed with outdoor air. An economizer controller may be connected to the sensors and actuators for controlling various properties of the air in the space. The air may be dehumidified by slowing down the movement of air across the cooling coil of the air handling unit.
