PROBLEM TO BE SOLVED: To suppress influence of the atmosphere in the case of opening a rear door to a small value by providing an air conditioner for diffusing the air toward forward upon reception of sensing of closing of the door and diffusing the air toward rearward upon reception of sensing of opening of the door by a sensor. SOLUTION: When a rear door 12 is closed, closing of the door 12 is sensed by a sensor 13. After sensing of the sensor 13, a fan motor 14b is continuously reversely rotated for a predetermined time in a cooling unit 14. Thus, the vicinity of the door 12 in a load chamber 11 can be rapidly returned to a predetermined temperature. Further, after a predetermined time is elapsed, the motor 14b is forward rotated. Then, the air cooled by a cooler 14a is again diffused toward forward. Thus, since the chamber 11 is held at a predetermined cooling temperature by the one unit 14 and an air flow layer is formed in an exist/ entrance of the chamber 11 in the case of opening the door 12, its cost can be reduced as compared with an air curtain. |
