The superiority is a point that one outdoor unit is superior to the other outdoor unit. For example, the above-mentioned EHP is superior.
As for the outdoor unit of the above-mentioned GHP,
The outdoor unit of GHP has a long maintenance time interval because it does not emit combustion gas and does not change engine oil, and has a low noise level during operation. Since the compressor is driven by the power of the gas engine, there is almost no power consumption during operation, and the heat generated by the engine can be used, so there is a feeling of rising during heating operation and the feeling of cold wind during defrosting operation. That's a few.

For example, this is notified (S5), and in order to supplement the insufficient capacity for the air conditioning load due to the stop of the malfunctioning outdoor unit, the EHP of step 8 described later
Then, the superiority of GHP is judged. On the contrary, if there is no unannounced outdoor unit, it is determined whether or not all of the outdoor units currently in operation are thermo-off (S6),
If there is at least one outdoor unit that is not turned off,
The operation is continued as it is. On the contrary, when all the outdoor units in operation are thermo-off, rotation of the outdoor units to be operated by thermo-on after that is performed, so that the advantage of EHP and GHP in step 8 described later is obtained. A sex judgment is made.

If there is no operation signal, the stop state is continued (S3). ), If there is the above-mentioned operation signal, it is judged from the calendar function and the clock function provided in the central control section 6 whether or not the operation situation allows the superiority of any of the outdoor units to be utilized (S8). If it is determined that the operating condition is one in which the superiority of the outdoor unit can be utilized, then one of the outdoor units that can utilize the superiority is selected (S9), and only the outdoor unit capable of operating in which the superiority is utilized is the indoor unit. It is determined whether or not the air conditioning load from S is satisfactory (S10), and if the capacity is not satisfactory, the other outdoor unit is also selected (S11).
