22 is a motor for driving the fan, 23 is a contact of the auxiliary relay 6 in the 14th (a), 25 is a normally closed contact, 26 is an auxiliary relay, 27 is a contact of the auxiliary relay 26, 29 is an electromagnetic contactor, and 30 is an electromagnetic contact. The contacts of the contactor 29 are shown and are connected as shown. Further, the electric circuit is also provided with a local start/stop switch 31, and the local start/stop switch 31 is connected in series to the electric motor 22 for driving the fan and the electromagnetic contactor 29.

を開始する。In the electric circuit of the No. 1 air conditioning unit and the No. 2 air conditioning unit described above, when each local start/stop switch 11.31 is in the ON state, when the operation button 3 is pressed, the auxiliary relay 6 is activated 7, and the Ω Contacts 7 and 8 are closed, and contact 7 causes auxiliary relay 6 to self-hold. Furthermore, when the contact 8 closes, the electric motor 2 for driving the fan is energized, and at the same time the electromagnetic contactor 9 is activated, and the contact 10 is closed, the electric motor 1 for driving the compressor is energized, and the No. 1 air conditioning unit is activated. Start driving.
