Property.
Fig. 5 shows the structural representation of air conditioner according to an embodiment of the invention.
As shown in figure 5, air conditioner 500 according to an embodiment of the invention, including：The control device 400 of air conditioner.
Air conditioner 500 according to an embodiment of the invention, by the control device 400 of the air conditioner, when temperature detection fills
When putting failure, according to target outdoor temperature corresponding with the current operating parameter of air conditioner (estimating obtained outdoor temp angle value)
The real time execution frequency of cooler compressor is controlled, can be avoided because temperature-detecting device failure can not obtain now
Outdoor temperature leads to not the real time execution frequency for effectively adjusting compressor, so cause air conditioner can not normal work, together
When compressor is avoided because of highest compressor operating frequency corresponding to the outdoor temp angle value that running frequency is estimated beyond this, and
The service life of air conditioner is detracted, wherein, the real time execution frequency is the compression that measures after the temperature-detecting device failure
The running frequency of machine.
Technical scheme is described in detail above in association with accompanying drawing, by technical scheme, can avoid
Because the outdoor temperature that temperature-detecting device failure can not obtain now leads to not effectively to adjust the real time execution frequency of compressor
Rate, so cause air conditioner can not normal work, while compressor is avoided because running frequency exceeds the outdoor estimated
Highest compressor operating frequency corresponding to temperature value, and the service life of air conditioner is detracted, wherein, the real time execution frequency is
After the temperature-detecting device failure, the running frequency of the compressor measured.
