A system supplies gas to a high-pressure gas-consuming apparatus and a low-pressure gas-consuming apparatus of a floating structure including a tank. The supply system includes: a first supply circuit, a second supply circuit, a return line, a first heat exchanger and a second heat exchanger. The return line includes a flow-regulating member. The supply system includes a device for managing the supply system which includes a control module to control the flow-regulating member based on the characteristics of the gas.

The gas supply system of this invention is furnished with a cylinder apparatus having a pneumatic valve that supplies process gas to a process chamber, and a solenoid valve that opens or closes said pneumatic valve by supplying or stopping the flow of valve actuating gas to said pneumatic valve; and a gas supply control apparatus that controls the actuation of the solenoid valve. In addition, said gas supply control apparatus comprises a main controller that controls the actuation of said solenoid valve during normal operation, and a sub-controller that senses an abnormal state of said main controller and if an abnormality is sensed, controls the actuation of said solenoid valve instead of said main controller.

According to one aspect of the present invention, a hydrogen fuel filling system includes a first flow passage through which hydrogen fuel supplied from a pressure accumulator that accumulates hydrogen fuel under pressure passes; a second flow passage through which hydrogen fuel supplied from the pressure accumulator passes, and which is arranged in parallel with the first flow passage; a switching valve that switches flow passages selectively from one of the first and second flow passages to another, or that switches flow passages between one and both of the first and second flow passages; and a control circuit that controls opening/closing of the switching valve, wherein a fuel cell vehicle using hydrogen fuel as a power source is filled with hydrogen fuel while switching the flow passages by the switching valve during supply from the pressure accumulator.

A control device of a gas charging device controls opening/closing of a control valve so that pressure increase rate of gas pressure in a tank when gas charging to the tank increases at a reference increase rate determined in advance. The control device, when gas charge to the tank begins, controls pressure increase rate at a high increase rate higher than the reference increase rate. After the difference between gas pressure in the tank when gas charging is performed at the high increase rate and gas pressure in the tank when the charging is performed at the reference increase rate has reached a predetermined pressure difference, the control device controls the opening/closing of the control valve so that gas charge to the tank is performed at the reference increase rate.

The invention relates to a gas container equipped with a gas distribution valve having an electronic device for measuring gas autonomy. Flow selection means allow a desired gas flow to be selected. The electronic device includes a pressure sensor. Signal processing means allow gas autonomies to be determined on the basis of the pressure signal and of the selectable gas flows. A selection component cooperates with the signal processing means in order to successively display, on data display means and in response to successive digital activations by the user of the selection component, the various selectable flow values and the various corresponding autonomies, with each flow value being simultaneously displayed with a corresponding autonomy.

The present disclosure provides systems and methods for refilling fluid containers. A fluid container may include a bottle and a valve assembly. The valve assembly may include two valves and be configured to engage with the bottle and a filling head or dispensing head. A system is configured to provide pressurized fluid to the refillable container, monitor filling, determine when to stop filling, and determine how much fluid was provided. The valve assembly may include a float mechanism coupled to one of the valves of the valve assembly to ensure fluid flow is stopped when the fluid container is full. The fluid, which can include carbon dioxide, is stored in a storage tank. A flow system provides the fluid to a filling head, which engages with the fluid container. The flow system includes a transfer pump, valves, and sensors configured to provide the fluid to the filling head.
