Abstract
The invention relates to a device and a method for filling pressurized-gas tanks, including a distributor, to feed a tank with pressurized gas, a refrigeration system including a circuit of refrigerant fluid and a heat exchanger for exchanging heat between the heat-transfer fluid and the flow of gas in the distributor, the circuit of heat-transfer fluid including, in series in a loop, a reserve of heat-transfer fluid, a member for setting the heat-transfer fluid in circulation in the circuit, and at least one evaporator ensuring heat exchange between the heat-transfer fluid and a source of cold, a bypass portion and a set of bypass valves allowing all or part of the heat-transfer fluid to bypass the heat exchanger of the distributor thereby cooling the heat-transfer fluid in the reserve and to accumulate cold energy therein independently of the need for cold energy in the distributor.
