摘要： A cooling system includes an expansion valve configured to exert a first pressure drop on refrigerant circulated through the cooling system. The cooling system also includes a plurality of capillary expansion tubes fluidly coupled in parallel to an output of the expansion valve and configured to exert a second pressure drop on the refrigerant circulated through the cooling system. The cooling system also includes a controller communicatively coupled to the expansion valve, wherein the controller is configured to control magnitude of the first pressure drop by instructing the expansion valve to adjust the valve position based at least in part on refrigerant mass flow expected to be supplied to the expansion valve to facilitate substantially uniformly distributing the refrigerant mass flow between each of the plurality capillary expansion tubes.

摘要： A solar powered cooling system that obtains a plurality of cooling temperatures in a simultaneous fashion. The system includes a heliostat field, a steam-Rankine cycle (SRC), absorption-refrigeration cycle (ARC), an ejector-refrigeration cycle (ERC) and a cascaded-refrigeration cycle (CRC). The heliostat field directs solar energy to a receiver included in the SRC to heat molten-salt. The heated molten salt transfers heat energy to form vapors of a first refrigerant. A steam turbine transfer the power to drive the vapor compression system (CRC) system and vapor at the turbine exit is fed to the ERC cooling system. The ERC achieves a first cooling temperature range by driving an ejector-nozzle by the vapors of the first refrigerant. The steam turbine drives a first compressor and a second compressor included in the CRC to obtain a second cooling temperature range. A condenser included in the ARC portion condenses the vapors of the first refrigerant to obtain a third cooling temperature range.

摘要： A system includes a control module and a monitor module. The control module selectively operates a component of the system in an ON state. The system receives power from an electrical grid. The monitor module selectively detects a fault event of the electrical grid in response to (i) an amount of current drawn by the component or (ii) a voltage of power received by the component. In response to detecting the fault event, the control module switches the component from the ON state to a second state, determines a first delay period according to a random process, identifies an apparent conclusion of the fault event, and in response to the apparent conclusion of the fault, waits for the first delay period before switching the component back to the ON state. The component consumes less power in the second state than in the ON state.
