とするマルチ形空気調和機。 A plurality of indoor units A to D each containing an indoor heat exchanger 18 are connected in parallel to an outdoor unit X containing a compressor 1 and an outdoor heat exchanger 7, and the The multi-type air conditioner is provided with an operation control means 42 for controlling the operation so that the refrigerant discharged from the compressor 1 is circulated to the indoor heat exchanger 18 of the indoor unit whose operation is requested according to the operation request. Furthermore, an abnormality determining means 45 determines whether or not each of the indoor units A to D can be operated, and when it is determined that any indoor unit is not operable, only the indoor unit that is not operable is stopped. abnormal unit stopping means 46, and the operation control means 42.
The present invention is characterized by being provided with an abnormal unit signal input stop means 47 for stopping the operation request signal from the indoor unit which cannot be operated by restricting the input of the operation request signal from the indoor unit which is operable. Multi-type air conditioner.
