Abstract: A plate heat exchanger is disclosed herein. In some instances, the plate heat exchanger may be disposed in an ice bin of a beverage dispenser for cooling one or more fluids. The plate heat exchanger may include a top plate, a bottom plate, an outer boundary wall, and a fluid flow path disposed between the top plate and the bottom plate. The fluid flow path may include an inlet and an outlet. A fin may be disposed within the fluid flow path from the top plate to the bottom plate between the inlet and the outlet.

Abstract: A transport refrigeration unit controls temperature within a transport refrigeration unit using a remote sensor or sensors. The transport refrigeration unit monitors cargo temperature with remote sensor(s) and air temperature to adjust air delivery speed or cooling capacity. Selected operation parameters are determined with consideration of both energy conservation and/or cargo quality. The transport refrigeration unit controls temperature using a first selected mode of operation or a second mode of operation.

Abstract: A refrigeration system includes a compressor having a first stage and a second stage; a heat rejecting heat exchanger including an inter-cooler and a gas cooler, the intercooler coupled to an outlet of the first stage and the gas cooler coupled to an outlet of the second stage; an unload valve coupled to an outlet of the intercooler and a suction port of the first stage; a flash tank coupled to an outlet of the gas cooler; a primary expansion device coupled to an outlet of the flash tank; a heat absorbing heat exchanger coupled to an outlet of the primary expansion device, an outlet of the heat absorbing heat exchanger coupled to the suction port of the first stage; and a controller for executing a startup process including controlling the unload valve to direct refrigerant from the intercooler to the suction port of the first stage.

Abstract: A refrigerant vapor compression system includes a compression device having at least a first compression stage (30a) and a second compression stage (30b) arranged in series refrigerant flow relationship; a first refrigerant heat rejection heat exchanger (80) disposed intermediate the first compression stage and the second compression stage for passing the refrigerant passing from the first compression stage to the second compression stage; a second refrigerant heat rejection heat exchanger (40) disposed downstream with respect to refrigerant flow of the second compression stage; a bypass line (90,130) positioned at least one of a discharge outlet port of the first compression stage and a discharge outlet port of the second compression stage; a bypass valve (92,132) disposed in the bypass line, at least one of the first compression stage and second compression stage bypassed and at least one of the first refrigerant heat rejection heat exchanger and the second refrigerant heat rejection heat exchanger bypassed

Abstract: A refrigerated transportation cargo container includes a transportation cargo container and a refrigeration unit disposed at an end of the transportation cargo container to provide a flow of supply air for the transportation cargo container. The refrigeration unit includes a housing and an evaporator fan (34) to urge the flow of supply air through the refrigeration unit. A kick plate assembly (40) includes a kick plate (46) extending from the refrigeration unit toward a floor of the cargo container and a baffle plate extending between the refrigeration unit and a sidewall of the cargo container. The kick plate assembly defines a discharge cavity to direct the flow of supply air toward the floor of the cargo container.

Abstract: A refrigerated transportation cargo container includes a transportation cargo container and a refrigeration unit located at an end of the transportation cargo container to provide a flow of supply air for the transportation cargo container. The refrigeration unit includes a housing having a front wall with one or more front wall openings therein. A back wall is located opposite the front wall and nearer to an interior of the cargo container relative to the front wall. One or more components of a refrigeration unit are installed in the housing via insertion through the one or more front wall openings.

Abstract: Operation of a transcritical refrigerant vapor compression system for supplying temperature conditioned air to a temperature controlled space is controlled when staging up or staging down to avoid undesirable overshoot and undershoot of the narrow temperature band bounding the control temperature set point for the temperature within the temperature controlled space.

Abstract: A refrigeration system (10) includes a compressor (20) having a first stage (20a) and a second stage (20b); a heat rejecting heat exchanger (40) having a fan (44) drawing ambient fluid over the heat rejecting heat exchanger, the heat rejecting heat exchanger including an inter-cooler (43) and a gas cooler(41), the intercooler coupled to an outlet of the first stage and the gas cooler coupled to an outlet of the second stage;, an unload valve (93) coupled to an outlet of the intercooler and a suction port of the first stage; a flash tank (70) coupled to an outlet of the gas cooler; a primary expansion device (55) coupled to an outlet of the flash tank; a heat absorbing heat exchanger (50) coupled to an outlet of the primary expansion device, an outlet of the heat absorbing heat exchanger coupled to the suction port of the first stage; and a controller (100) for executing a startup process.
