Shi Jinhang alarms and stops being promoted the rotational frequency of compressor.Wherein, case temperature alarm threshold value is lower than maximum permissible temperature value.
If the case temperature of compressor is less than preset case temperature alarm threshold value, compressor housing is indicated without reason
Barrier continues to lift up the rotational frequency of compressor until the base temperature of compressor reaches the object run temperature of seat at this time.
After waiting the first preset time (such as a few minutes), further judge whether pedestal Current Temperatures are less than pedestal
Highest allows running temperature, and pedestal Current Temperatures and pedestal highest allow whether the difference of running temperature is less than preset threshold.
If pedestal Current Temperatures, which are less than pedestal highest, allows running temperature, and pedestal Current Temperatures and pedestal highest allow
The difference of running temperature is less than preset threshold, then controls air conditioner shutdown, and be judged to may not operate obstruction failure.Wherein, if
When in refrigerant pipeline there is no may not operate obstruction failure, then preset time rear base Current Temperatures can be substantially reduced, so that
The pedestal Current Temperatures of preset time be less than pedestal highest running temperature or pedestal Current Temperatures and pedestal highest allowed to permit
Perhaps the difference of running temperature, which is greater than, is arranged this preset threshold.
In one embodiment of the invention, after waiting preset time, further whether judge pedestal Current Temperatures
Less than pedestal highest allow running temperature, and pedestal Current Temperatures and pedestal highest permission running temperature difference whether be less than it is default
