  • Publication number: 20240027111
    Abstract: An evaporator for a refrigeration plant including a high-pressure chamber, a low-pressure chamber, a filter screen interposed between the high-pressure chamber and the low-pressure chamber, and a communication conduit linking the high-pressure chamber to the low-pressure chamber. The filter screen passes the working fluid in the gaseous phase from the high-pressure chamber towards the low-pressure chamber, and blocks the passage of the working fluid in the liquid phase from the high-pressure chamber towards the low-pressure chamber and vice versa. The communication conduit essentially allows the working fluid in the liquid phase to pass from the high-pressure chamber to the low-pressure chamber, and opposes a free passage of the working fluid in the gaseous phase from the high-pressure chamber to the low-pressure chamber and vice versa.

  • Patent number: 9528657
    Abstract: Device for filling a container with a gas under pressure, especially hydrogen in a tank of a vehicle, comprising at least one source (1, 2, 3, 6) of gas pressurized to a first pressure, called high pressure, a transfer circuit (201, 36, 13, 14, 136, 146) capable of selectively connecting the source or sources (1, 2, 3, 6) of pressurized gas to the tank to be filled, the transfer circuit comprising control members (204, 132, 142) for controlling the flow of the gas from the source or sources (1, 2, 3, 6) to the tank, the transfer circuit further including at least one cooling exchanger (9), for cooling the pressurized gas, wherein the cooling exchanger (9) comprises a hot flow circuit (99) for the pressurized gas to be cooled, a cold flow circuit (98) for a cold cooling fluid, and a refrigeration hold-over medium (5), the refrigeration hold-over medium (5) being in direct heat exchange, on the one hand, with the cold fluid of the cold circuit (98) and, on the other hand, with the pressurized gas to be cooled o

  • Patent number: 8517062
    Abstract: A method for filling a gas tank at a pressure P2 from at least one gas source at a pressure Pi, P1 being higher than V2, said container and said at least one gas source being connected by a duct allowing the passage of gas from one to the other, the filing being carried out at a flow rate which is, at the end of the filling, lower than the initial flow rate, wherein said method comprises several successive filling steps 1 to i, each of the steps being carried out with a filling flow rate D1 to Di for a time t1 to ti, i being an integer higher than or equal to 2, the flow rate of a step i-1 being higher than the flow rate of the step i,; characterized in that the successive filling steps 1 to i are adapted for producing a controlled heating of the container that maximizes the heat dispersal in said container without increasing the temperature inside the container beyond the maximum accepted temperature for the container, and in that the sum of ti is between 1 and 7 minutes, preferably between 1 min 30 sec and

  • Patent number: 8360112
    Abstract: The inventive method for filling a pressure gas container from a gas source pressure with a high pressure for a predetermined filling time selected or calculated prior to filling and at a determined temperature consists in forming a connection in the form of a fluid passage between the source and container, in carrying out a plurality of the passage opening-closing sequences during predetermined sub-intervals of the predetermined filling time, wherein the curve of a current pressure in the container follows, according to a time, a theoretical straight line linking the pressure measured prior to filling and after thereof during the filling time, the predetermined filling time is subdivided into a number of the time sub-intervals ranging from two to several hundreds and having respective determined duration, preferably ranging from 5 and 20 seconds.
