Automatically cleaning pattern is executed to indoor unit；If average value is not more than the 4th preset value relative to the change rate of standard current value,
Automatically cleaning pattern is not executed to indoor unit.In this way, first by by the dew of the coil temperature of indoor unit and air
Point temperature compares, to judge whether the indoor unit of air conditioner has condensation generation, when the coil temperature of indoor unit is not less than air
Dew-point temperature not will produce condensation on the indoor unit of air conditioner, and the wind turbine electric current of indoor unit will not be affected due to condensation,
Therefore can the concrete numerical value of the 4th preset value be arranged slightly lower, such as the 4th preset value is set as 0.1, i.e., multiple wind turbine electricity
When the average value of flow valuve is more than 0.1 relative to the change rate of standard current value, air conditioner just can execute automatically cleaning mould to indoor unit
Formula.Certainly, the 4th preset value can also be other numerical value, and those skilled in the art can flexibly set the in practical applications
The concrete numerical value of four preset values, as long as can judge that machine does not generate condensation indoors by the separation that the 4th preset value determines
In the case of indoor unit whether tie ash.In addition, in order to consider wind of the condensation to indoor unit when machine generates condensation indoors
The influence of electromechanics stream, it should the second default settings must be higher than the 4th preset value always.In addition, similar with the first preset value
Ground, third preset value could be provided as 2 DEG C, and those skilled in the art can flexibly set third preset value in practical applications
Concrete numerical value, as long as the separation determined by third preset value can judge whether the coil temperature of indoor unit excessively high i.e.
It can.
