Abstract: A climate-control system includes a working fluid circuit and a storage tank. The working fluid circuit has a first compressor, a first heat exchanger, a second heat exchanger, a flash tank, and a third heat exchanger. The first heat exchanger receives working fluid discharged from the first compressor. The flash tank is disposed downstream the first heat exchanger and includes an inlet and first and second outlets. The first outlet provides working fluid to the third heat exchanger disposed between the flash tank and the first compressor. The second outlet provides working fluid to the first compressor. The storage tank contains phase-change material that is thermally coupled with the second heat exchanger of the working fluid circuit.

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 system may include a compressor, a heat exchanger, an expansion device, a lubricant separator, and a flow path. The compressor includes a compression mechanism. The heat exchanger receives compressed working fluid from the compressor. The expansion device is disposed downstream of the heat exchanger. The lubricant separator receives lubricant and working fluid discharged from the compression mechanism and provides separated lubricant to the compression mechanism. The flow path may receive working fluid from the heat exchanger and may provide working fluid to the heat exchanger. The flow path may extend between a first location disposed between the heat exchanger and the expansion device and a second location disposed between the heat exchanger and the compressor. The working fluid from the flow path may absorb heat from the separated lubricant.
