Starting, and the axial-flow fan 20 for controlling the other side continues to run with the slow-speed of revolution.For example, when user indicates: the axial-flow fan in left side
20 outlet air, when the axial-flow fan 20 on right side is closed, the axial-flow fan 20 in the control of control device 60 left side is according to wind set by user
Speed rotation, and controlling the fan on right side leads to room to be less than preset rotation speed continuous running to avoid right area atmosphere draught-free
Interior machine can not radiate or cold scattering.Similarly, when being used to indicate the axial-flow fan 20 for only opening right side, the fan in left side is controlled with small
In preset rotation speed continuous running.In the present embodiment, preset rotation speed very little is only used for auxiliary indoor unit heat dissipation/cold scattering, such as can
To be set as 10r/s.
According to being described above, environmental information detection device 40 is set between two air outlets of shell, that is, environment
Information detector 40 is set to the middle of indoor unit, can 360 ° without dead angle detect indoor environment.Environmental information inspection
It surveys device 40 to be configured to controllably detect indoor environment information, indoor environment information includes: the human surface temperature of user, user
Location information and user are at a distance from air conditioner indoor unit.In the present embodiment, environmental information detection device 40 further comprises
Human body temperature detection module 41, infrared detection sensing module 42, as shown in Figure 6.Infrared detection sensing module 42 can sense room
Interior user number can obtain the position of each human body and can sense human body and its distance, because of environmental information detection device
40 are located on air conditioner indoor unit, it can be considered as human body at a distance from air conditioner indoor unit at a distance from human body.Using infrared
Quantity, the position etc. of sensor or other sensors detection human body belong to what those skilled in the art were noted, specific former
Reason is no longer described in detail herein.Human body temperature detection module 41 is able to detect the human surface temperature of indoor user.Utilize infrared ray
Radiation sensitive human body temperature is also what art technology was noted, and concrete principle is no longer described in detail herein.
Control device 60 is configured to after receiving indoor environment information above-mentioned, controls the unlatching number of axial-flow fan 20
The revolving speed and air supply direction of amount, axial-flow fan 20, so that air supply mode is more suitable and current indoor environment while making to have leisure
Adjust indoor unit more energy saving.Such as: in refrigeration, when detecting that user human surface temperature is higher, improve corresponding through-flow wind
The revolving speed of fan keeps user's body-sensing comfortable to reduce user's body temperature as early as possible.When detecting distance of user's human body to air conditioner indoor unit
When less than pre-determined distance, the revolving speed of corresponding axial-flow fan is reduced, and controls wind deflector or puts the outlet air that leaf makes axial-flow fan
Human body is avoided in direction, to prevent cold air blow-through.Above-mentioned control device 60 automatically controls the mode of axial-flow fan operation, is not
Implement in the case where receiving user operation instruction, if user has sent operational order, control device 60 is according to user's
Actual instruction controls air conditioner indoor unit operation.
It will be understood by those skilled in the art that in case of no particular description, it is so-called in the use of the new type embodiment
"upper", "lower", "left", "right", " cross ", " perpendicular ", "front", "rear" etc. are for indicating that the term of orientation or positional relationship is with air-conditioning
