PROBLEM TO BE SOLVED: To provide a chill/refrigerator van having an air curtain unit for enabling a blower fan to rapidly exhibit a prescribed function, when door is opened. SOLUTION: The chill/refrigerator van has a freezer/refrigerator where a door mechanism for opening or closing the carry-in/carry-out opening is provided while the carry-in/carry-out opening for carrying in or out a load is formed, and a refrigerating machine for cooling the inside of the freezer/ refrigerator. The blowing fan of the air curtain unit for forming an air flow layer along the carry-in/carry-out opening is operated at a steady rotation region, when the operation of the refrigerating machine is instructed and the door mechanism is open. When the operation of the refrigerating machine is instructed and the door mechanism is open, operation is made at an idle rotation region which is lower than the steady rotation region. |
