Abstract: The disclosure describes a system that includes an evaporator, an accumulator downstream of the evaporator, a centrifugal compressor downstream of the accumulator, a first heat exchanger stage downstream of the centrifugal compressor, and a second heat exchanger stage downstream of the first heat exchanger stage. The evaporator is configured to cool a conditioned air stream using a refrigerant. The accumulator is configured to store excess refrigerant. The centrifugal compressor is configured to compress the refrigerant. The first heat exchanger stage is configured to cool the refrigerant using environmental air. The second heat exchanger stage is configured to cool the refrigerant from the first heat exchanger stage using a portion of the excess refrigerant from the accumulator.

Abstract: A vapor-compression system includes a centrifugal compressor configured to increase a pressure of a refrigerant based on at least one of an activation of a device or the device being equal to or above a first threshold temperature. A fluid communication system is configured to provide, to the device, a portion of the refrigerant in a liquid state. The portion of the liquid refrigerant in a liquid state is configured to have a saturation temperature equal to or below the first temperature threshold.

Abstract: A pressure control system includes an overboard valve in indirect communication with a first enclosed environment and in direct communication with a second enclosed environment. The first environment is suitable for human occupancy and configured to receive pressurized air from an environmental control system. The second environment is configured to receive the pressurized air from the first environment. An inboard valve is configured to supply a discharge of pressurized air from the second environment. An outflow valve is configured to regulate a discharge of air from the first environment to an area outside the first and second environments. A positive pressure relief valve configured to regulate a discharge of air from the first environment. A negative pressure relief valve configured to regulate an ingress of air into the first environment. A control valve is configured to regulator and supply pressurized air from the first environment to a compressor.

Abstract: A system includes an air pressurization system (APS) and an environmental control system (ECS). The APS is configured to supply pressurized supply air to the ECS. The ECS includes a primary heat exchanger (PHX), an air-driven turbine downstream of the PHX, and a vapor cycle refrigeration system (VCRS) downstream of the PHX. The PHX is configured to cool the supply air using environmental air. The turbine is configured to power a vapor cycle refrigeration system (VCRS) using the supply air. The VCRS is configured to cool the supply air to generate cabin air.

Abstract: A system includes a manifold, a power unit, and a throttle valve. The manifold is configured to receive cabin discharge air from a cabin. The cabin discharge air includes cabin discharge air from a waste region of the cabin. The auxiliary power unit is fluidically coupled to the manifold and configured to draw cabin discharge air from the manifold. The throttle valve is configured to control flow of cabin discharge air from the manifold to the power unit. A method includes receiving a pressure measurement for the manifold and a pressure setpoint for the manifold representing a predetermined flow of cabin discharge air from the cabin to the manifold. The method includes determining and outputting, based on the pressure measurement and the pressure setpoint, a control signal for at least one manifold inlet configured to control flow of cabin discharge air from the cabin to the manifold.
