    Abstract: A compressor may include first and second scrolls, and an axial biasing chamber. Spiral wraps of the scrolls mesh with each other and form compression pockets including a suction-pressure compression pocket, a discharge-pressure compression pocket, and intermediate-pressure compression pockets. The axial biasing chamber may be disposed axially between the second end plate and a component. Working fluid disposed within the axial biasing chamber may axially bias the second scroll toward the first scroll. The second end plate includes outer and inner ports. The outer port is disposed radially outward relative to the inner port. The outer port may be open to a first one of the intermediate-pressure compression pockets and in selective fluid communication with the axial biasing chamber. The inner port may be open to a second one of the intermediate-pressure compression pockets and in selective fluid communication with the axial biasing chamber.

    Abstract: A compressor may include a shell assembly, first and second scrolls, and a valve assembly. The shell assembly may define a discharge chamber. The first scroll may be disposed within the discharge chamber and may include a first end plate and a first spiral wrap. The first end plate may include a discharge passage in communication with the discharge chamber. The second scroll may be disposed within the discharge chamber and may include a second end plate and a second spiral wrap. The first and second spiral wraps define fluid pockets therebetween. The second end plate may include a port selectively communicating with one of the fluid pockets. The valve assembly may be mounted to the second scroll and may include a valve member that is movable between open and closed positions to allow and restrict communication between the port and the discharge chamber.

    Abstract: A climate control system includes an electrochemical device in fluid communication with at least one fluid conduit that also includes a first heat exchanger, an expansion device, and a pump, but may be free of any condensers. A working fluid is circulated in the fluid conduit that has a composition that undergoes a reversible hydrogenation and dehydrogenation reaction when it passes through the electrochemical device when a potential is applied thereto. The climate control system includes a heat rejection system in the form of a recirculation loop having a second heat exchanger configured to cool a portion of the working fluid exiting the electrochemical device and a recirculation pump that circulates the portion of the working fluid exiting the electrochemical device through the second heat exchanger and back to an inlet of the electrochemical device. Methods for rejecting heat from an electrochemical climate control system are also provided.

    Abstract: An electrochemical climate control system circulates a working fluid comprising ammonia (NH3) and hydrogen (H2). An evaporator volatilizes liquid ammonia for a refrigeration effect. An electrochemical device can increase a total pressure of the working fluid and/or a first partial pressure of ammonia and decrease a second partial pressure of hydrogen when an f is applied. A condenser cools the working fluid/transforms ammonia to a liquid. A separator separates liquid ammonia from gas phase hydrogen. A heat exchanger may be provided downstream of the evaporator. The system may include an ejector combining vapor phase ammonia and gas phase hydrogen in a pressurized stream. A second electrochemical device is optionally included that decreases a pressure of gas phase hydrogen exiting the separator and which generates electrical potential that is transferred to the first electrochemical device. Such high efficiency systems may be free of any mechanical pumps or moving parts.

    Abstract: A foil bearing assembly includes a cylindrical body that defines a cooling fluid passage between a radial outer surface and a radial inner surface of the cylindrical body. The foil bearing assembly includes a foil bearing retained within the cylindrical body and in thermal communication with the radial inner surface of the cylindrical body. The foil bearing assembly is connectable to a bearing housing such that intake and outlet ports of the foil bearing assembly are connected in fluid communication with a coolant inlet passage and a coolant outlet passage defined by the bearing housing. The foil bearing assembly is interchangeable with a second foil bearing assembly having at least one of a cooling fluid passage, a foil bearing, and a cylindrical body inner diameter different than the corresponding cooling fluid passage, the foil bearing, and the cylindrical body inner diameter of the first foil bearing assembly.
