Abstract: A heat exchanger has a fin pack, with a first supply header and a first return header at the first end of the fin pack. A first group of U-shaped tubes is provided with a first segment extending from the first supply header to the second end of the fin pack, and a second segment extending from the second end of the fin pack to the first return header. A second supply header and a second return header are also provided at the first end of the fin pack. A second group of U-shaped tubes is provided with a first segment extending from the second supply header to the second end of the fin pack, and a second segment extending from the second end of the fin pack to the second return header, where the second plurality of U-shaped tubes is disposed inwardly of the first plurality of U-shaped tubes.

Abstract: An open-front refrigerated display case is provided having a medium temperature zone disposed above a low temperature zone in a generally vertically-stacked arrangement. A spillover airflow-diverting device is disposed between the medium temperature zone and the low temperature zone and is configured to direct spillover air from the medium temperature zone air curtain (and ambient air entrained therewith) in a direction away from the open front of the low temperature zone. The spillover airflow-diverting device may include louvers configured to direct a gravity-induced flow of the spillover air in an outward direction away from the open front of the low temperature zone, or may include fans to collect spillover air and forcibly direct it in an outward direction away from the open front of the low temperature zone. The outwardly directed spillover air may be discharged in the form of an ‘outer layer’ for an air curtain on the low temperature zone.

Abstract: A refrigerated device has an evaporative condensate dissipation system for disposing water from its cooling element during defrosting. Progressive stages operating at increasing temperatures provide a cascading evaporative dissipation. One pan receives water from the cooling coil and operates at ambient temperature for a first evaporative dissipation. Overflow from the pan flows through a first standpipe to a second stage. The second stage includes another pan that receives water from the first standpipe, and is heated by hot gas refrigerant for operation at a higher second temperature to provide a second evaporative dissipation. Overflow from the second pan is directed through a second standpipe to a third stage. The third stage includes a third pan that receives the water from the second pan via the second standpipe, and is heated by an electric heater for operation at a higher third temperature to provide a third evaporative dissipation.

Abstract: A refrigerated case has an insulated support structure that serves as a display platform and provides contact cooling for preservation of fresh food products. The case includes a base and an insulated support structure coupled to the base. The insulated support structure includes a platform portion configured for placement of food products directly thereon, and a front wall portion and a rear wall portion. The front and rear wall portions support a canopy, so that the insulated support structure and the canopy substantially enclose and define a temperature controlled space. The insulated support structure includes a top surface facing the temperature controlled space, and a bottom surface opposite the top surface with an interior space defined between the top and bottom surfaces. A pattern of cooling passages are arranged within the interior space along an underside of the top surface at the platform portion to provide contact cooling to food products disposed on the platform portion.

Abstract: A defrost system for a temperature controlled storage unit includes an enclosure providing a space for storage of products. A refrigeration system has a supply line and a return line coupled to a cooling element to circulate a refrigerant through the cooling element to provide cooling to the space. A control module initiates a plurality of defrost modes on a predetermined frequency and for a predetermined duration by reducing a flow rate of the refrigerant through the cooling element so that a superheat temperature of the refrigerant in the cooling coil is increased to a predetermined range.

Abstract: An apparatus (10) for helping to protect an occupant of a vehicle includes an inflatable vehicle occupant protection device (12). An inflator (14) provides inflation fluid for inflating the protection device (12). A vent member (30) includes at least one vent opening (62) for venting the inflation fluid. A vent cover (100) has a closed condition for blocking fluid flow through the at least one vent opening (62) and an open condition for permitting fluid flow through the at least one vent opening. The vent cover (100) includes a side wall (110) that has at least one portion (134, 372) that projects from the side wall into the vent member (30) to help maintain the vent cover in the closed condition.

Abstract: An apparatus (10) includes an inflatable device (12) for helping to protect a vehicle occupant, and an inflator (14) with inflation fluid outlets (24). A vent member (30) connected with the inflator (14) has a vent wall (60) having at least one vent opening (62). A vent cover (100) includes an outer wall (110) having first and second end portions (112 and 114). The vent cover (100) has a closed condition clamped on the vent wall (60) and covering the vent opening (62), and an open condition enabling fluid flow through the vent opening. An actuatable device (130) has an unactuated condition connecting the first and second end portions (112 and 114) to maintain the vent cover in the closed condition, and an actuated condition releasing the end portions to release the vent cover to the open condition to vent inflation fluid from the apparatus (10).
