Abstract

A device and process for refuelling containers with pressurized gas comprising a pressurized gas source (2), a transfer circuit (4) comprising one upstream end (5), 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 refrigerant cooling loop circuit (20) comprising a bypass conduit (13) comprising an upstream end connected to the outlet of the compressor (8) and a downstream end connected to the refrigerant cooling loop circuit (20) upstream the compressor (8) inlet and bypassing the condenser section (9) and expansion valve (10), the device comprising a bypass regulating valve (15) for controlling the flow of refrigerant flowing into the by-pass conduit (13).
