PROBLEM TO BE SOLVED: To provide gas-filling equipment which is capable of reducing design pressure of a pressure accumulator while reducing the size of a compressor.SOLUTION: The gas-filling equipment 1 is provided with a compressor 4 and a pressure accumulator 5. The relationship between filling pressure and a target flow rate is determined beforehand according to the volume of a tank 3. The filling pressure is detected to determine the target flow rate. The flow rate of the gas being supplied into the tank 3 is controlled according to the target flow rate. When the target flow rate is equal to or less than the maximum discharge rate of the compressor 4, gas is supplied to the tank from the compressor 4 only. When the target flow rate is greater than the maximum discharge rate, gas is supplied to the tank from the compressor 4 and the pressure accumulator 5. |
