Cold Storage Doorway With Airflow Control System And Method
US Patent:
8287337, Oct 16, 2012
Filed:
Jan 4, 2007
Appl. No.:
11/649513

International Classification:
F24F 9/00
US Classification:
454188, 454189
Abstract:
A conditioned vestibule, control system, and method are disclosed for use with a cold storage doorway that separates warm and cold sides. A heater warms an air stream discharged across the doorway by the vestibule. A control unit operates the heater to maintain an air stream temperature. The control unit continuously monitors the air stream temperature and operates the heater to maintain the air stream temperature in a non-saturated state based on a humidity ratio. One embodiment calculates first and second temperatures based, respectively, warm and cold side tangent lines to a psychrometric saturation curve and based on the humidity ratio. The tangent lines are based on humidity and temperature sensed on the warm and cold sides. The air stream is warmed to at least the greater of the first and second temperatures. One embodiment controls air flow to adjust the humidity ratio to more efficiently operate the vestibule.

F25D017/04
US Classification:
454188, 62256, 62408, 454192, 454195
Abstract:
A conditioned vestibule for a cold storage doorway is disclosed. The vestibule includes a frame that supports inner and outer moveable door-forming members. The vestibule also includes a heater that circulates air between the inner and outer door-forming members and a variable-speed fan that varies flow of the air between the inner and outer door-forming members. In one embodiment, the airflow from the fan increases upon the opening of the door-forming members and decreases upon the closing of the door-forming members.

International Classification:
A47J 47/00
US Classification:
454173000
Abstract:
A conditioned vestibule for a cold storage doorway is provided having a trackless, bi-folding door operated by an actuator that rotates a first arm portion. The first arm portion rotates about a first end. A second arm portion is connected pivotally to a second end of the first arm portion at a hinge. The second arm portion rotates relative to the first arm portion at the hinge, in response to movement of the actuator. A door body is connected to at least one of the first and second arm portions. In one embodiment, the vestibule further includes an air curtain, including a fan that circulates air across a doorway opening across into which the first and second arm portions extend, a discharge means that discharges the air across the opening, and a return means that communicates discharged air to the fan.
