PROBLEM TO BE SOLVED: To carry out easy and quick automatic adjustment to a set value of a temperature of cold air blowing out from a blowout opening, and to carry out automatic adjustment to an optimal value of air capacity also in a vortex tube. SOLUTION: In the temperature controller, an electropneumatic regulator 8 is provided in a supply line of compressed gas to a generator 4 of the vortex tube, a motor operated proportional control valve 13 is provided on a tip of a hot air tube 5, and a temperature signal and a temperature signal of a humidity sensor 9 and an air capacity sensor 16 provided in the cold air blowout opening 7 of the vortex tube are respectively compared with set values in a temperature controller 11 and an air capacity controller 17 to provide a humidity control signal and an air capacity control signal to be supplied to a sequence circuit 15. Control of a drive circuit 12 of the electropneumatic regulator 8 based upon the air capacity control signal, control of the drive signal 12 of the electropneumatic regulator 8 based on the temperature control signal, and control of a drive circuit 14 of the motor operated proportional control valve 13 based upon the temperature control signal are carried out based upon a sequence carrying out alternative selection.
