A frost control system is described for inhibiting and removing frost from the door of a storage locker. Relatively cool air is received by an inlet to the frost control system at an inlet placed above the door. The air is drawn into the system by a blower which forces the air through the ducts of the system. The air passes through strip heaters within the vertical ducts of the defrost system positioned on either side of the door. The warm air is discharged horizontally across the bottom portion of the door and simultaneously rises creating a blanket of relatively warm air in comparison to the ambient area. Discharge apertures are included in the ends of the vertical ducts which blow a portion of the warmed air to the base of the door to enhance coverage of the door by the warmed air.
A frost control system for removing from and preventing the formation of vapor condensation and/or frost upon a cold storage locker door having a top, a base, first and second side edges, a cold-side surface and a warm-side surface, said system comprising:
A frost control system for a door having a top, a base, first and second side edges, a cold-side surface and a warm-side surface, said system comprising:
A frost control system for a door disposed in an opening in an enclosure wall separating a volume of relatively warm fluid from a volume of relatively colder fluid wherein header means and side wall means extend outwardly from said wall into said volume of relatively warm fluid adjacent said opening and above a floor means, said system comprising:
A frost control system for removing from and preventing the formation of vapor condensation and/or frost upon a cold storage locker door having a top, a base, first and second vertical edges, a cold-side surface and a warm-side surface, said system comprising:
A method of frost control to reduce frost formation on a cold storage locker door having a cold-side surface and a warm side surface, and a header and side walls extending from adjacent said door on the warm side, said method comprising the steps of withdrawing air from the vicinity of said warm side surface adjacent said header, heating the withdrawn air, transporting said air to the vicinity of the bottom said side wall and said door on said warm side, and discharging said air from said heater means along said warm side surface.
