Step S3242 determines the rotating speed of target of each axial-flow windwheel according to the target wind speed；
Blower is specially counter-rotating fan.Two axial-flow windwheels air shape in rotation disturbance air-conditioned wind tunnel in the opposite direction
At distinguished and admirable.Difference according to target wind speed and current blower wind speed determines the rotating speed of target of each axial-flow windwheel respectively, makes two
A axial-flow windwheel cooperation rotation makes the wind speed of air conditioner can reach target wind speed.
Step S3243 controls each axial-flow windwheel and runs according to corresponding rotating speed of target.
In the present embodiment, target wind speed is reached by the setting of counter-rotating fan, is conducive to improve air conditioner
Outlet air efficiency.
Further, according to default human thermal comfort inductance value and human comfort relevant parameter, target user place is determined
Before the step of target measuring point temperature and target measuring point wind speed of position, further includes:
Step S00 determines estimated average hotness index according to human comfort relevant parameter；
Obtain human comfort relevant parameter after, current PMV can by by human comfort relevant parameter (measuring point temperature,
Relative humidity, measuring point wind speed, radiation temperature, human activity amount and clothing situation etc.) it substitutes into preset comfort sense formula and calculates
It arrives.Preset comfort sense formula can be specifically arranged according to specific comfort demand, current environment feature etc..
Step S01, judges whether estimated average hotness index meets default heat comfort condition；
If not satisfied, then executing according to human thermal comfort inductance value and human comfort relevant parameter is preset, determine that target is used
The step of target measuring point temperature and target measuring point wind speed of family position；
If satisfied, thening follow the steps S02.
After obtaining estimated average hotness index, it can determine whether estimated average hotness index is equal to default Studies of Human Body Heat
In the either no pre-set interval being located at where presetting human thermal comfort inductance value of comfortable inductance value, if so, determining estimated average heat
Feel that index meets default heat comfort condition, if it is not, then determining that estimated average hotness index is unsatisfactory for default heat comfort condition.
Step S02, control air conditioner are run according to current state.
By the above-mentioned means, wind-warm syndrome timely can be gone out by target when the user in air conditioner action space is uncomfortable
Degree and target wind speed adjust the operation of air conditioner in phase, make the environment of air conditioner action space that can meet the comfortable of user
Property demand.
