Abstract

A device for refuelling containers with pressurized gas, comprising a pressurized gas source (2), a transfer circuit (4) intended to be removably connected to a container (3), the device (1) comprising a refrigeration system for cooling the gas flowing from the gas source (2) prior to its entering into the container (3), the refrigeration system comprising a refrigerant cooling loop circuit (20) comprising, arranged in series, a compressor (8), a condenser section (9), an expansion valve (10) and an evaporator section (11), the refrigeration system comprising a cold source (12) in heat exchange with the condenser section (9) and a heat exchanger (7) located in the transfer circuit (4) and comprising a heat exchange section between the gas flowing in the transfer circuit (4) and the evaporator section (11), the device comprising an electronic controller (21) connected to the expansion valve (10) and configured for controlling cooling power produced by the refrigeration system via the control of the opening of the expansion valve (10), characterized in that the electronic controller (21) is configured to generate or receive a signal indicative of the cooling power needed at heat exchanger (7) for cooling the flow of gas in the transfer circuit through the heat exchanger (7) and, in response, for controlling the cooling power produced by the refrigeration accordingly.
