本実施形態では、上記のように、水素タンク１４と高圧水素貯蔵タンク１２とが、接続部３０にて一箇所で連結されるため、水素タンク１４側に、第１水素供給管路１８と第２水素供給管路２０とに夫々別個に接続される複数の供給口を設ける必要がなく、水素タンク１４の構造の簡略化を図ることができる。また、第１水素供給管路１８と第２水素供給管路２０とが被覆材５０により一体化されているため、水素タンク１４への水素供給側である高圧水素貯蔵タンク１２側の配管を１本の管として取り扱うことができ、水素充填時の取り回しが容易になり作業性が向上する。
Sturdy and responsive: The product TC90 higher-strain thermocouple is created for temperature checking for the duration of hydrogen refuelling.
そこで、本発明は、水素タンクへの水素充填時における水素タンク内の温度変化を抑制するのに適した温度の水素を該水素タンクへ迅速に充填できると共に、水素充填終了直後の水素タンク内を略大気温度とすることが可能で、該水素タンクへの水素充填量を十分に確保できる水素充填装置及び水素充填方法を提供することを目的とする。

Such as, the temperature can be a important variable when refuelling with hydrogen. Monitoring it calls for a specific thermocouple. A maker of H2 refuelling systems has hence opted for instrumentation from WIKA.
The heat insulating device 24 suppresses an increase within the temperature in the hydrogen cooled from the cooling device 22 and prevents frost formation and condensation around the outer wall surface area of the 2nd hydrogen offer pipe twenty by which the cooled hydrogen flows. Offered. Therefore a heat insulating signifies 24, a so-termed warmth insulating product for instance glass wool, rock wool or foamed resin product is wound around the outer wall area of the second hydrogen provide pipe twenty, and the second hydrogen offer pipe twenty is a double pipe.
本発明によれば、水素タンクへの水素充填時における水素タンク内の温度変化を抑制するのに適した温度の水素を該水素タンクへ迅速に充填できる。また、水素タンクへの水素充填時における水素タンク内の温度上昇を低減することが可能となり、該水素タンクへの十分な量の水素を充填できる。
前記第１の水素供給管路と前記第２の水素供給管路とは、被覆材により一体化されていることを特徴とする水素充填装置。
The hydrogen filling approach Based on Anybody of statements eight to 10, A hydrogen filling method, wherein the hydrogen tank is crammed with hydrogen at the next temperature In the beginning of hydrogen filling in the hydrogen tank.
(kJ/kg) cv designates the state in the Command volume [0055] The enthalpy is often based on measuring the temperature and tension with the hydrogen in the circulation stream, if possible at a degree near or in the tank inlet, Together with the mass circulation to the tank staying calculated or calculated from Original and last disorders. To estimate the final temperature of your fuel all through or following a refueling process, the actual heat transfer, Q, within the gasoline in to the tank wall must be estimated. Due to the fact Equation [two] only offers facts for the internal Electricity condition of your tank a Device, such as the National Institute of Expectations and Know-how (NIST) Thermophysical Home Database, is used to lookup the temperature from The inner Vitality Attributes of your target gas, e.g., hydrogen. A curve in shape to your NIST facts utilized below for inner Vitality is illustrated in FIG. two. The distinction between the adiabatic inside Vitality along with the measured interior Vitality (U2 at measured temp and stress) is the quantity of warmth that is transferred with the Manage quantity, and might be established from check information.

Time curve for just a hydrogen tank refueling process during which the adiabatic temperature, Tadiabatic, is Utilized in calculating the warmth transfer. The warmth transferred from your hydrogen can be explained by Equation [5] as comprehensive over. This supplies a Instrument for analyzing true test info to ascertain the quantity of warmth which has been transferred from the hydrogen fuel out with the Handle volume, or into the construction of the tank. Take note which the adiabatic internal Power is based only on First ailments in the tank (Original mass of hydrogen and Preliminary temperature) along with the conditions of the hydrogen sent within the station (enthalpy and fill mass).
