PURPOSE:To variably control ventilation quantity according to the number of passengers so as to accomplish energy saving and improvement of environmental comfortableness in a car by detecting a load inside the car and controlling wind quantity of a ventilation device arranged inside the car according to the dimensions of the detected load. CONSTITUTION:In an elevator car 1, plural ventilation fans 2a-2c, a load detector 3 detecting the number of passengers as a load, and a temperature detector 4 detecting the temperature of the inside are respectively arranged. On the other hand, a ventilation side controller 5 normally arranged above the elevator car 1 is provided with an inputting unit 6 connected to respective detectors 3, 4 and the like, an outputting unit 7 connected to the respective ventilation fans 2a-2c, and a control computing processor 8. In the control computing processor 8, ventilation wind quantity is controlled according to the dimensions of the detected load. In other words, ventilation is controlled with large ventilation quantity in the case of a large number of passengers, while controlled with little ventilation quantity in the case of a small number of passengers. |
