1. A process for refueling containers with pressurized gas with a device comprising gas source and a transfer circuit for transferring compressed gas from the gas source to a container, the process comprising the steps of:
cooling a heat exchanger located in the transfer circuit, the heat exchanger being in heat exchange with the pressurized gas flowing from the source to the container(s), wherein said step of cooling comprises production of a cooling power in an evaporator section of a refrigerant cooling loop circuit, the cooling loop circuit comprising, arranged in series, a compressor, a condenser section, an expansion valve and the evaporator section, the condenser section being in heat exchange with a cold source; and
regulating a suction pressure at an inlet of the compressor via control of a speed of the compressor and control of a quantity of refrigerant compressed by the compressor which is reinjected via a bypass conduit upstream of the compressor without flowing through the condenser section and the expansion valve.
