Claims

[Scope of utility model registration request]

For one outdoor unit equipped with a compressor, a heat exchanger on the non-use side, an outdoor blower, etc., a throttle device and a heat exchanger on the use side constitute a refrigerant circulation circuit together with the compressor, the heat exchanger on the non-use side, etc. In a system in which a plurality of indoor units equipped with an automatic temperature controller that controls on/off the operation of an indoor blower installed in the machine and also controls a second auxiliary relay on/off by using second contacts, and a second auxiliary relay of the first auxiliary relay. A control circuit is connected to each of the indoor units, and includes an on-off switch that is provided in parallel with the contact of the switch and energizes the second auxiliary relay when closed, regardless of the operation of the first auxiliary relay. An operating circuit is provided correspondingly and in which the contacts of each of the second auxiliary relays are connected in series, and the opening/closing circuit controls the operation of the compressor on and off according to the opening/closing state of the operating circuit. Air conditioner provided with means.
