PURPOSE:To perform air conditioning during the operation with capacity corresponding to the number of passengers by adding the call number of an elevator floor to the number of passengers detected by a load detector to set a reference value for controlling capacity of an air conditioner. CONSTITUTION:A reference value of a circuit 1 is formed by a call button of an elevator, and a reference value of a circuit 2 is formed by a load detector. The circuit 1, the circuit 2 and a compressor 3 are connected in series. Consequently, a current value flowing in a motor for driving the compressor 3 is controlled automatically by increasing and decreasing a value obtained by adding resistance values of the circuit 1 and the circuit 2. As a result, air conditioning inside of an elevator cage can be concluded during the elevator waiting time, namely, during the travelling toward a floor, where a call is generated. Air conditioning can be thereby performed during the operation with capacity corresponding to the number of passengers. |
