The present invention is to provide a hydrogen refueling system capable to cool down the H2 pre-cooling heat exchanger fast enough when a FCV enters the HRS, so that there is no or very minimal waiting time for the customer before starting refueling. A hydrogen refueling system including a cryogenic fluid tank that stores a cryogenic fluid, a dispenser that supplies H2 to a vehicle, including a heat exchanger that cools H2 with the cold and/or cryogenic fluid provided from the cryogenic fluid tank, an inlet line that sends the cold and/or cryogenic fluid to the heat exchanger from the cryogenic fluid tank, an outlet line that collects the cryogenic fluid fed from the heat exchanger, and an injection valve that is provided in the inlet line.

Disclosed is a liquefied natural gas storage apparatus. The apparatus includes a heat insulated tank and liquefied natural gas contained in the tank. The tank has heat insulation sufficient to maintain liquefied natural gas therein such that most of the liquefied natural gas stays in liquid. The contained liquefied natural gas has a vapor pressure from about 0.3 bar to about 2 bar. The apparatus further includes a safety valve configured to release a part of liquefied natural gas contained in the tank when a vapor pressure of liquefied natural gas within the tank becomes higher than a cut-off pressure. The cut-off pressure is from about 0.3 bar to about 2 bar.

The present invention relates to a cylinder holder (10) for a cylinder (20) for pressurized storage of therapeutic oxygen, the cylinder holder (10) comprising a receptacle (11) arranged to hold the cylinder (20) in a holding position, characterized in that the cylinder holder (10) comprises at one or more than one cylinder switch (12) adapted to be actuated by the cylinder (20) when received in the receptacle (11) in the holding position. A corresponding supply system (100) for therapeutic oxygen and a corresponding supply method are also part of the present invention.

A fuel-filling system of an LPG vehicle is provided. LPG remaining in an LPG bombe is forcibly fed to a fuel injection pipe using a fuel pump and is used to pressurize new LPG, which is injected into the fuel injection pipe, toward the LPG bombe. Thus, the LPG bombe is refilled with new LPG despite warmer weather conditions.

Fluid tanks in a hospital or similar environment include sensors to detect, e.g., state and location, which can be communicated to a central station where this data can be processed to permit predictions of resource usage and enable automated management of the fluid tanks.

A HRS comprising at least a HRS center module, a HRS dispenser module and a first hydrogen supply line facilitating flow of hydrogen between the HRS center module and the HRS dispenser module, the HRS center module comprises a safety controller and a process controller, wherein data is communicated between the safety controller and safety components of the HRS dispenser module via a safety communication channel, and wherein data is communicated between the process controller and process components of the HRS dispenser module via a process communication channel.

The present invention provides a control system (10) for managing the supply of bottled gas to users (12), the system comprising: a gas cylinder system (14) having a gas cylinder (15) for receiving and distributing gas contained therein; a first electronic monitoring system (16) associated with said gas cylinder system (14) and operable to monitor parameters associated with said cylinder system (14); a second monitoring system (18) associated with one or more locations (A-F) in which said cylinder may reside and being operable to monitor the presence or absence of said cylinder within said one or more locations (A-F); and a computer system (20) in communication with each of said second monitors (18) for receiving information therefrom relating to the presence or absence of said cylinder system (14) in said one or more locations (A-F).

To provide a fluid supply apparatus capable of preventing inconveniences cause by cut of a signal line when a filling hose is separated through an emergency separation pipe joint. The fluid supply apparatus (100: fluid supply apparatus for supplying fluid such as hydrogen gas and gasoline) includes a supply system for transporting fluid such as hydrogen gas and gasoline in a housing main body while measuring flow rate of the fluid; a control mechanism for controlling the supply system; a hose (2) introduced from the supply system and having a nozzle (1) at an end thereof; and a signal line (3) along the hose (2), wherein the signal line (3) is detachable.

A vehicle has a fuel system that includes a controller that determines when the vehicle is in a refuel mode or a run mode based on a connection of a refuel nozzle to a vehicle connection of the vehicle. The controller controls a fuel pump input selector, a vehicle fuel pump, and a fill/run fuel selector such that fuel is pumped from a storage tank external to the vehicle into a vehicle fuel tank by way of the vehicle fuel pump in the refuel mode, and fuel is pumped to an engine of the vehicle from the vehicle fuel tank by way of the vehicle fuel pump in the run mode.

A tube-array-type liquid nitrogen container includes a container body having a mouth; a tube array component received in the container body; and a top cap sealing the mouth from above. The top cap is rotatable in the mouth. The tube array component is composed of a plurality of holding tubes. The holding tube is opened at one end thereof, wherein the opening thereof faces the top cap. The top cap has at least one tube access passing therethrough. Each tube access is atop covered by a tube access cover. The tube-array-type liquid nitrogen container uses a tube-array component composed of the a plurality of holding tubes to store the freezing tubes, and is cooperated with the rotatable top cap and an external robotic arm, thereby improving space utilization and thermal insulation, effectively ensuring safety of the freezing tubes, and facilitating automatic storage of freezing tubes.
