Fig. 1 is the flow chart of the control method of the present invention according to shown by an exemplary embodiment
As shown in Figure 1, the present invention provides a kind of control method of outdoor fan of air-conditioner rotating speed, start shooting available in air-conditioning
Operation or air-conditioning internal system pressure instantaneous pressure control to adjust the rotating speed of outdoor fan in the case of changing greatly, specifically
, the process step of the control method includes：
The indoor temperature of room area residing for S101, acquisition air-conditioning；
In the present embodiment of the present invention and following embodiment, it is illustrated with split-type air conditioner, split-type air conditioner
Mainly include indoor unit and outdoor unit, wherein, indoor unit is arranged at the room areas such as parlor, bedroom, and outdoor unit is then arranged at and builds
Build the outdoor areas such as beyond the region of objective existence wall, roof.Indoor unit is equipped with temperature sensor, can sense the temperature change in indoor environment, this
Sample, in step S101, indoor temperature can detect to obtain by the temperature sensor, and as this control flow
Indoor temperature parameter.
Generally, the room area such as parlor, bedroom is respectively provided with an indoor unit, each indoor unit is configured with independent
Outdoor unit, i.e. common domestic air conditioning type is by an indoor unit and outdoor unit work, therefore, for the application present invention's
The air-conditioning of control method, its indoor temperature gathered is the temperature parameter of the specific room area residing for its indoor unit, e.g., right
In the indoor unit for being arranged at parlor, air-conditioning performs the real time temperature that indoor temperature acquired in step S101 is parlor region；
Similarly, for being arranged at the indoor unit in bedroom, then acquired in air-conditioning be bedroom real time temperature.
And for application scenarios such as office building, hotels, then mostly using the business air conditioner type of " one drag more ", i.e. a room
Outer machine connects two or more indoor unit work at the same time, and among these, different indoor units is respectively at different rooms again
In inner region, therefore, for above-mentioned business air conditioner type, it is in the indoor unit for the state that enables respectively by independent temperature
The indoor temperature of the corresponding room area of sensor collection, afterwards, by Predistribution Algorithms such as weighting algorithms, is calculated indoor temperature
Average, and the indoor temperature parameter using the average as this control flow.
S102, the temperature gap according to indoor temperature and target indoor temperature, determine and control outdoor fan with outside first
Machine wind speed is run；
In step s 102, indoor temperature is indoor temperature parameter acquired in step S101, and target indoor temperature
The temperature value then reached for the expectation interior that user is inputted by remote controler or control panel, among these, for above-mentioned family
With air conditioner type, because it corresponds to structure type of an outdoor unit for an indoor unit, then in the target chamber in step S102
Temperature value is a single set temperature value；And for above-mentioned domestic air conditioning type, since it is more for an outdoor unit correspondence
The structure type of platform indoor unit, and user may set different indoor units respectively the different target Indoor Temperature of numerical values recited
Degree, therefore, the target indoor temperature can be more adding in the target indoor temperature enabled set by the indoor unit of state
Weigh the average being calculated；Alternatively, air-conditioning can prestore the default objects at different moments for Various Seasonal or in one day
Indoor temperature value, then can be using the default objects indoor temperature value as the target indoor temperature in step S102.
For example, in one embodiment, the default objects indoor temperature value set by air-conditioning includes but not limited to, summer 28
DEG C, 20 DEG C of winter, etc.；Alternatively, including for the default objects indoor temperature value at different moments on the same day of summer but not
It is limited to, 8 points are 28 DEG C, and 12 points are 25 DEG C, and 15 points are 24 DEG C, etc..In this way, the more indoor units in business air conditioner type are connect
When the target indoor temperature of received setting differs greatly, air-conditioning can be by finding the default objects indoor temperature of system intialization
It is worth to the target indoor temperature of this control flow.
In one embodiment, under cooling in summer operating mode, target indoor temperature is generally below indoor temperature；And make in the winter time
Under thermal condition, target indoor temperature is then generally greater than indoor temperature.Therefore, for the ease of to the first outer machine wind in outdoor fan
Speed determines that control flow of the present invention is outside the temperature gap according to indoor temperature and target indoor temperature, definite and control room
Before wind turbine is with the first outer machine wind speed operation, the operational mode of air-conditioning is also predefined, wherein, operational mode includes refrigeration mould
Formula and heating mode.
In this way, when operational mode is refrigeration mode, temperature gap subtracts what target indoor temperature obtained for indoor temperature
First temperature gap；When operational mode is heating mode, temperature gap subtracts what indoor temperature obtained for target indoor temperature
Second temperature difference.
Alternatively, the absolute value of the temperature gap of indoor temperature and target indoor temperature can be directly calculated in step S102, and
Determined according to the absolute value and control outdoor fan to be run with the first outer machine wind speed.

Section, so as to change the wind speed of outdoor fan, outdoor fan rotating speed is divided into multiple wind speed by the present invention according to rotating speed height in advance
Section, the wind speed interval as corresponding to 1000~1500r/min is high wind wind speed, 500~1000r/min are right for apoplexy wind speed
The wind speed interval answered, and 0~500r/min is then the wind speed interval corresponding to low wind wind speed, in this way, when the first temperature gap is expired
During the above-mentioned a certain Rule of judgment with preset threshold parameter of foot, you can adjust the wind speed of outdoor fan to foregoing corresponding
Rotating speed, to control the wind speed actually reached of outdoor fan to be in matched wind speed interval.
Alternatively, in another embodiment, outdoor fan is set for rotating speed control using different stalls and wind speed is adjusted, such as
Outdoor fan includes 1,2,3,4,5 this five gears, wherein, the rotating speed gear corresponding to the low wind wind speed of 1 gear, in 2 and 3 gears
The how corresponding rotating speed gear of wind wind speed, the rotating speed gear corresponding to the high wind wind speed of 4 and 5 gears.In this way, when the first temperature gap is expired
