Abstract: A system for maintaining thermal separation between first and second adjacent rooms or spaces. The system includes a vestibule with at least a first compartment, and other embodiments may include two or more compartments, such that the vestibule provides a passageway between the first and second rooms. At least one blower draws air from the first room through an air intake, and back into the first room through an exhaust. The system further includes an exhaust port from the first compartment in fluid communication with the exhaust, to exhaust air from the first compartment into the first room. During operation, a vacuum is formed within the first compartment that provides thermal separation between the first and second adjacent rooms.

Abstract: A method for adjusting pressure at an inlet of a blast freezer. The method includes positioning an airfoil proximate to the inlet, the inlet having a perimeter. The airfoil includes a strip of material having a length and being attached to the freezer along at least one side of the inlet, the strip of material being spaced from the perimeter of the inlet by an offset distance. The offset distance at any location along the length of the strip of material is the closest distance between the strip of material and the perimeter at that location. The offset distance varies substantially along at least a portion of the strip of material. Cold air is flowed in the blast freezer past the inlet and over the airfoil so that the flow of air past the inlet is disrupted and creates a resultant adjustment to the air pressure at the inlet.
