Temperature value, to obtain the value of first operating parameter.It is appreciated that being indoor unit return air temperature in first operating parameter
Degree, when second operating parameter is indoor unit evaporating temperature, the air conditioner room unit includes two temperature sensors 40, institute
It states two temperature sensors 40 and is joined with obtaining corresponding first operation for the temperature of detection indoor unit associated components respectively
The value of number and second operating parameter.
The indoor machine wind shelves regulating device 30 is according to using the first preset duration as described in the timing acquisition indoor unit of interval
The value of first operating parameter and second operating parameter, by calculating the corresponding period by interval timing of the second preset duration
The difference of interior first operating parameter and second operating parameter, when the difference is all higher than the first predetermined threshold value, with
The value of first variable is the rotation wind shelves increase that the other difference of wind shelf grade controls the indoor fan 20, or small in the difference
When the second predetermined threshold value, the rotation wind shelves that the indoor fan 20 is controlled using the value of the first variable as the other difference of wind shelf grade drop
It is low.
The value of first preset duration be according to indoor unit provide refrigeration and heating capacity of water, runnability,
The conjunction that the factors such as day and night temperature and the temperature in four seasons variation of different regions are chosen by lot of experimental data comprehensive analysis
Just when value range can be 5-10min, and the value of the first preset duration described in different regions can be selected according to actual conditions
Take different desired values.
First operating parameter/second operating parameter is temperature value, can be used for indicating indoor heat exchanger temperature (such as
Coil temperature), indoor unit pressure and temp, indoor temperature, indoor unit evaporating temperature, indoor unit return air temperature, indoor target temperature,
Indoor unit target evaporating temperature etc., value can be detected by the temperature sensor 40 being set on indoor unit and be obtained, or
A preset value in indoor unit default setting can also be what user was arranged by terminals such as remote controler, mobile phone, tablet computers
One value.When first operating parameter is indoor unit evaporating temperature, second operating parameter can be indoor unit target
Evaporating temperature；When first operating parameter is indoor unit return air temperature, second operating parameter can be that indoor unit steams
Send out temperature, etc..
The temperature sensor 40 being set on indoor unit is able to detect that respective chambers machine component (such as indoor unit coil pipe)
Real time temperature, the indoor unit obtain corresponding one or more using the first preset duration as interval timing by temperature sensor 40
The value of a operating parameter, and by acquired one or more operational parameter values and operating parameter obtain time point be stored in it is described
On the memory of indoor unit, or the value for being stored in one or more operating parameters on the indoor unit memory is read, tool
No matter running body parameter value acquisition modes can use the combination of which kind of acquisition modes, the knot obtained depending on actual demand
Fruit is to obtain the value of corresponding first operating parameter and the second operating parameter.Wherein, the temperature sensor 40 can be temperature-sensitive
The equipment that packet, infrared temperature sensor etc. have temperature sensing function.
Second preset duration is the desired value chosen by analysis according to lot of experimental data, for determining
Every how long carry out once calculate with obtain the different time points stored in the corresponding period it is corresponding it is described first fortune
The difference of row parameter and second operating parameter.In the present embodiment, the value of second preset duration is described first
The integral multiple of preset duration, such as 1-3 times, when the value of second preset duration is 1 times of first preset duration,
It is corresponding in second preset duration that there are one the differences；It is described first default in the value of second preset duration
