Abstract
A humidity control apparatus for controlling the humidity level of air within a given area. The apparatus includes a plurality of control valves connected in fluid flow communication to a fluid supply source for injecting water into the air within the area for controlling the humidity level within the area. A controller outputs electrical signals controlling the activation of the fluid flow control valves based on temperatures and sensor inputs within the area input to the controller along the with a multi-position switch which controls the present humidity set point within the area as well as the delay between activation of various numbers of the control valves in sequence with a predescribed time delay.
Claims6
A humidity control apparatus for controlling the humidity within an area comprising:
- a plurality of fluid flow control means for controlling the injection of fluid into the air within the area;
- input switch means for establishing a pre-set humidity set point for the area;
- humidity sensing means, mounted within the area, for sensing the current humidity level in the air within the area;
- air flow sensing means for sensing the presence of air flow within the area;
- and
- control means including a stored program and responsive to the input switch means, the air flow sensing means and the humidity sensing means for automatically activating the fluid flow control means to maintain the humidity level of the air within the area at the preset humidity set point.
A humidity control apparatus for controlling the humidity within an area comprising:
- a plurality of electrically operated solenoid valves for controlling the injection of fluid into the air within the area;
- input switch means for establishing a preset humidity set point for the area;
- humidity sensing means, mounted within the area, for sensing the current humidity level in the air within the area;
- switch means for setting a preset amount of time delay for energization of the valves;
- on/off switch means, switchable between both "on" and "off" positions corresponding to the activation and the de-activation, respectively, of the time delay;
- temperature sensing means, mounted within the area, for sensing the temperature of the air within the area;
- temperature and humidity set point display request input means;
- display means, responsive to the control means, for displaying the preset humidity set point and temperature as the preset humidity set point and temperature are requested;
- air flow sensing means for sensing the presence of air flow within the area;
- and
- control means including a stored program and responsive to the input switch means, the air flow sensing means and the humidity sensing means for automatically activating the valves to maintain the humidity level of the air within the area at the preset humidity set point, and responsive to the switch means and the on/off switch means for delaying the energization of the valves a preset amount of time delay as set by the switch means when the on/off switch means is in the "on" position, and responsive to the temperature sensing means and the temperature and humidity set point display request input means for controlling the display means to display the temperature and humidity set point as requested.
