    摘要： The method is based on the comparison of local vapor concentrations at the inlet and outlet refrigeration ports and taking action based on that comparison. Control apparatus is installed inside a refrigeration enclosure (10), adjacent to a port (14,15), preferably at the lowermost port (14). If the enclosure (10) contains multiple ports (201,202) at similar height, then each port (201,202) has a form of the control apparatus attached to it. The control apparatus adjusts a flow of vapor leaving the interior of the enclosure (10). The control apparatus includes a duct assembly (17,214,224,300,401,501,601) and a blower system (26,210,220,403,503,603). The bottom portion of the duct assembly (17,214,224,300,401,501,601) is a tunnel enclosure (20,22) through which a conveyor belt (16,203) passes. Connected to an inside edge of the tunnel enclosure is a duct (23) that extends upward from the conveyor belt (16,203). A blower (26,210,220,403,503,603) for this duct (23) either sucks vapor away from the conveyor belt (16,203) or blows vapor from the enclosure interior (12) toward the belt (16,203). Regardless of the flow direction, a vapor curtain forms inside the tunnel enclosure and represents a transitional region from all vapor to all air. Control of the blower (26,210,220,403,503,603) for the duct assembly is based on vapor concentrations in the tunnel enclosures (20,22) adjacent to each port (14,15,201,202). A microprocessor compares measured concentration levels and alters the blower motor (27,211,221,404,504,604) frequency in such a manner as to minimize the difference in concentration levels at each port (14,15,201,202).

    摘要： A cooling tunnel system that includes a conveyor for carrying objects through a tunnel chamber. The conveyor enables a cooling fluid to pass therethrough and about the objects. A plurality of slot means feeds the cooling fluid to the conveyor means. Each slot means includes at least one aperture for enabling vapor flow onto and about the objects. A plenum adjacent the plurality of slot means distributes the cooling fluid. And at least one fan in the tunnel chamber causes a flow of the cooling fluid into the plenum and through the slot means with sufficient velocity to impinge upon and cool the objects and to recirculate the cooling fluid within the tunnel chamber.
