Abstract

An environmental air conditioner including an air entrance, an air exit, a heat exchanger placed between the entrance and exit and an air circulation fan. The entrance opens and closes through entrance vanes driven by motor. The exit opens and closes through a door activated by a vertically slidable motor. Air direction control vanes are extended through entrance through the exit for varying the direction of the discharged air. Before the door be opened or closed, the air control vanes are automatically moved upwards toward a clear space position for avoiding the interference with the movement of the door. When the exit and the entrance are going to close the entrance vane motor is operated before the door motor secures that the entrance and the exit are completely closed in simultaneous form, even if it takes more time for the entrance vanes travel on all its state completely closed. A sensor determines when the door reaches its almost closed state and the door motor continues operating during a period after for securing with the door completely closes.
