Disclosed is a refrigerant gas injection tube having a double-tube structure for a handler. The injection tube includes a dry air tube injecting/discharging dry air; a refrigerant gas tube having an external diameter which is smaller than the inner diameter of the dry air tube and arranged in the dry air tube; and a refrigerant gas injection hole penetrating the dry air tube and the refrigerant gas tube. The refrigerant gas injection hole may be formed to spray the refrigerant gas injected to the refrigerant gas injection tube to the outside of the dry air tube without spraying the refrigerant gas into the dry air tube. |
