Abstract

PURPOSE:To make it possible to carry out an air conditioning operation by a compact construction when the device is in a fault by driving a compressor provided on the outdoor side by a forced drive signal from the indoor side when the indoor control part is in a fault. CONSTITUTION:In the air conditioner which has an inverter and also has controllers 1 and 9 on the indoor side and the outdoor side, respectively, and controls the outside controller 9 by a control signal from the indoor side controller 1, in a case where the controller 1 is in a fault, when a forced drive switch 7 is turned ON, a contact 7a is turned ON and a transmission line 10 assumes a high level. When the time of high level is more than the time set in the program, the compressor 6 is turned ON through an inverter controlling part 9 and is driven. It is possible to carry out the air conditioning operation by a simple construction even when the indoor controller is in a fault.

The operation of the above device will be explained using the flowchart shown in FIG. This flowchart is an example of an extracted part of the transmission signal reception program. If the control device is normal, a serial signal as shown in FIG.
The signal is sent from the inverter controller 9 to the inverter controller 9. Further, when the control signal is in the OFF state, the transmission line 10 becomes LOW level. Therefore, when the indoor control section fails, if the forced operation switch 7 is turned on, the contact 7a is also turned on and the transmission line 10 is switched on.
The level becomes Hi level as shown in the figure (B). If the time of this Hi level is longer than the time set in the program,
The compressor 6 is turned on and operated via the inverter control section 9. Note that if the transmission line 10 is configured to be at Hi level when the control signal is in the OFF state, the forced signal level may be set to LOW.
