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.
Claims66
A system for controlling humidity of air from an output of an air handling unit having a cooling mechanism and an air mover, comprising:
- a first damper proximate to an input of the air handling unit;
- a first actuator connected to said first damper;
- a humidity sensor proximate to the output of the air handling unit;
- and
- a controller connected to said first actuator and humidity sensor;
- and
- wherein:
- adjusting said first damper affects a speed of air moving through the cooling mechanism;
- decreasing the speed of air moving through the cooling mechanism decreases humidity of the air from the output of the air handling unit;
- and
- increasing the speed of air moving through the cooling mechanism increases humidity of the air from the output of the air handling unit.
A system for controlling humidity of air in a space comprising:
- an air mover having an input, a cooling mechanism and an output connected to the inlet of the space;
- a first air flow adjustor proximate to the input of said air mover and the outlet of the space;
- a second air flow adjuster proximate to an outside supply of air, to said first air flow adjuster and to the input of said air mover;
- a third air flow adjuster proximate to the outlet of the space, to the outside supply of air and to said first air flow adjuster;
- a first actuator connected to said first air flow adjuster;
- a second actuator connected to said second and third air flow adjusters;
- a controller connected to said first and second actuators;
- and
- a humidity sensor situated in the space and connected to said controller.
A method for controlling a climate control system for an enclosure, the climate control system including one or more conduits for passing an air stream past one or more cooling coils for cooling and/or dehumidifying the air stream, the method comprising the steps of:
- activating the one or more cooling coils to cool and/or dehumidify the air stream;
- and
- selectively restricting the air flow in the one or more conduits to reduce the velocity of the air stream past the one or more cooling coils for increased dehumidification.
An apparatus for controlling a climate control system for an enclosure, the climate control system including one or more conduits for passing an air stream past one or more cooling coils for cooling and/or dehumidifying the air stream, the apparatus comprising:
- means for activating the one or more cooling coils to cool and/or dehumidify the air stream;
- and
- means for selectively restricting the air flow in the one or more conduits to reduce the velocity of the air stream past the one or more cooling coils for increased dehumidification.
A system for controlling humidity of air from an output of an air handling unit having a cooling mechanism and an air mover, comprising:
- a first damper proximate to an input of the air handling unit;
- a first actuator connected to said first damper;
- a humidity sensor proximate to the output of the air handling unit;
- and
- a controller connected to said first actuator and humidity sensor;
- and
- wherein:
- adjusting said first damper affects a speed of air moving through the cooling mechanism;
- decreasing the speed of air moving through the cooling mechanism decreases humidity of the air from the output of the air handling unit;
- and
- increasing the speed of air moving through the cooling mechanism increases humidity of the air from the output of the air handling unit.
