摘要:
A refrigerated merchandiser includes a display case defining a product display region having an open-front isolated from the ambient air of the store by means of a downwardly directed inner air curtain of relatively cold refrigerated air and a downwardly directed outer air curtain of relatively warmer air established via an improved curtain air admission assembly. The curtain air admission assembly defines a plenum atop the refrigerated display through which the flow of air substantially reverses direction when passing from a first flow passage to a second flow passage. This reversal of flow direction serves to distribute the air flow more uniformly along the length of the display case.

A refrigerated merchandiser includes a display case defining a product display region having an open-front viewing area. A first air outlet is associated with the display case for directing a first air stream generally downwardly across the front viewing area along a first path, and a second air outlet is associated with the display case for directing a second air stream generally downwardly across the front viewing area along a second path outwardly of the first air stream. The first air stream and the second air stream are directly adjacent to one another and the first air stream exits the first air outlet at a first discharge velocity and the second air stream exits the second air outlet at a second discharge velocity, where the second discharge velocity is at least 1.4 times greater than the first discharge velocity.

A multi-band air curtain forms a separation barrier at an interface between a first environment having a fluid at a first condition and a second environment having a fluid at a second condition. A first stream (55) of a fluid is directed along a first path (45) generally parallel to the interface between the first environment and the second environment. A second stream (65) of fluid is directed along a second path (75) generally outwardly at an angle of divergence with the first path (45). A third stream (65) of a fluid is directed along a third path (95) between the first path (45) and the second path (75) at a first interior angle with said first path (45) and at a second interior angle with said second path (75). A refrigerated merchandiser (10) is also disclosed having a display case having an interior defining a product display region (30) having an open front and first (34), second (70) and third (58) air outlets for directing first (55), second (65) and third air (85) streams, respectively, across the open front of the refrigerated merchandiser in a divergent manner.

A refrigerated merchandizer includes a display case defining a product display region having an open-front isolated from the ambient air of the store by means of a downwardly directed inner air curtain of relatively cold refrigerated air and a downwardly directed outer air curtain of relatively warmer air. The outer curtain of relatively warmer air is directed downwardly and outwardly away from the inner air curtain of relatively cold air at a divergent angle with respect to the inner air curtain.

A container temperature control system having an inner container and a receptacle in which the inner container can be positioned. A thermoelectric based heat transfer unit is positioned in an opening in the receptacle such that an interior portion thereof is by the inner container and an exterior portion thereof is outside with heat being selectively transferable between these interior and exterior portions.

An ejector (38) has ports (40, 42, 44) for receiving a motive flow and a suction flow and discharging a combined flow. The ejector has a motive flow inlet, a suction flow inlet (42), and an outlet (44). A suction flow flowpath extends from the suction flow inlet. A motive flow flowpath extends from the motive flow inlet to join the suction flow flowpath and form a combined flowpath exiting the outlet. The ejector comprises a plurality of motive flow nozzles (100, 302, 402, 602, 702, 802) along the motive flow flowpath. The motive flow nozzles are oriented to impart a tangential velocity component to the motive flow. A plurality of diffusers (130, 304, 404, 604, 704, 804) are along the combined flowpath and are oriented to recover the tangential velocity from the combined flow.

A heat exchanger includes a first header, a second header and heat exchange tubes that extend between the first header and the second header. A fm is located between two adjacent heat exchange tubes, and the fm includes fin plates each having louvers. Each of the louvers includes a first louver section, a second louver section and a third louver section between the first louver section and the second louver section. The third louver section includes a drain portion that extends downwardly relative to the first louver section and the second louver section.

摘要:
A heat exchanger is described comprising a distributor having an outer housing and including a plurality of substantially parallel plates disposed within the housing and configured to partition an input two-phase flow into a series of primarily single-phase layers. A heat exchanger is described comprising a distributor having an outer housing including a plurality of substantially parallel channels disposed therein, each channel configured to uniformly and independently convey a portion of a homogenous input two-phase flow from an input of the distributor to an output of the distributor.
摘要:
An ejector (200; 400; 600; 700; 800) has a housing (202) and an insert. The housing has an upstream end (206) and a downstream end (208) and a branch (220). A primary flowpath extends from the upstream end and a secondary flowpath passes through the branch to join the primary flowpath. The insert (204; 402) is within the housing and extends from an upstream end (250) to a downstream end (252). The insert has a motive nozzle (240) having an inlet and an outlet. A mixer (242) is at least partially downstream of the motive nozzle. One or more passages (304) are positioned such that the secondary flowpath extends through the branch and through the one or more passages to join the primary flowpath, at least one portion of the insert being of less robust material than a material of the housing.
摘要:
A heat exchanger assembly for an aircraft control has an aircraft control for controlling an operation of an aircraft. The aircraft control is in thermal communication with a first fluid. A first thermoelectric device is configured to transfer heat between the first fluid and the second fluid against a temperature gradient of the first fluid and the second fluid. A temperature sensor is provided for sensing a temperature of the first fluid. A temperature control is also configured to control the first thermoelectric device based on an input from the temperature sensor.
