When outdoor has natural wind to blow over, stabilizer 7 can drive housing 2 to rotate, and the second base 12 rotates relative to the first base 11, makes the direction that the air inlet 211 of the heat dissipation wind channel 21 in housing 2 blows towards natural wind.Anemobiagraph 3 can measure the flow velocity of natural wind, and this flow velocity signal is sent to controller.
Pipeline connector 91 and power connector 92 are all located on the second base 12, when the second base 12 rotates relative to the first base 11, pipeline connector 91 can avoid refrigerant pipeline to be wound around mutually, power connector 92 can prevent power line to be wound around mutually, thus ensures the normal work of air-conditioner outdoor unit 100.
If the wind speed of the natural wind that anemobiagraph 3 detects meets the radiating requirements of air-conditioner outdoor unit 100, the first wind deflector 81 can be utilized to make natural wind blow in housing 2, by natural wind, outdoor heat exchanger 6 is dispelled the heat; If the wind speed of the natural wind that anemobiagraph 3 detects cannot meet the radiating requirements of air-conditioner outdoor unit 100, then controller controls actuator 5 and starts and rotate with driven vane 4, utilizes the rotation of blade 4 to produce wind and dispels the heat to the outdoor heat exchanger 6 in housing 2.
In sum, according to the air-conditioner outdoor unit 100 of the embodiment of the present invention, by housing 2 being located on the second base 12, and the second base 12 is located on the first base 11 rotationally, the direction utilizing stabilizer 7 to make the air inlet 211 on housing 2 to blow towards natural wind, natural wind is made to enter housing 2 by air inlet 211, for outdoor heat exchanger 6 dispels the heat.Meanwhile, measured the wind speed of natural wind by anemobiagraph 3, controller connects wind velocity signal and controls startup and the stopping of actuator 5 according to wind velocity signal, and when wind speed is less, utilizing actuator 5 driven vane 4 to rotate, is that outdoor heat exchanger 6 dispels the heat by the rotation of blade 4.Thus natural wind and blade 4 can be utilized to dispel the heat for outdoor heat exchanger 6, complete machine power can not only be reduced, and can electric energy be saved.
In addition, the invention also discloses a kind of cooling control method of air-conditioner outdoor unit, wherein, air-conditioner outdoor unit is the air-conditioner outdoor unit that above-described embodiment describes.
As depicted in figs. 1 and 2, air-conditioner outdoor unit can comprise: base assembly, housing, anemobiagraph, blade, actuator and controller.Wherein, anemobiagraph can be located on housing, and anemobiagraph can be used for detecting the flow velocity of air-flow, and blade can be located in the heat dissipation wind channel in housing, and the clutch end of actuator is connected with blade and rotates with driven vane, and controller can be connected with actuator with anemobiagraph respectively.
As shown in Figure 3, comprise the following steps according to the cooling control method of the embodiment of the present invention:
S10: adjust the unlimited direction that the second base makes air inlet, make it relative with air current flow direction.Such as, as shown in Figure 1, air-conditioner outdoor unit can be provided with stabilizer, when there being natural wind to blow over, adjust the second base by stabilizer, make the unlimited direction of air inlet relative with the flow direction of air-flow, like this, natural wind can enter heat dissipation wind channel from air inlet, is the parts heat radiations such as the outdoor heat exchanger in housing.
S20: anemobiagraph detects air-flow velocity Vt, can provide foundation for follow-up control work.
S30: according to the size of the preset value V0 of air-flow velocity Vt and air-flow velocity, controller judges whether that starting actuator controller can compare the preset value V0 of air-flow velocity Vt and air-flow velocity, thus provide foundation for follow-up control work.
S31: as Vt < V0, controller controls actuator and starts.When the flow velocity Vt of the air-flow that anemobiagraph detects is less than the preset value V0 of air-flow velocity, can think that now the flow velocity deficiency of natural wind thinks that the outdoor heat exchanger in housing dispels the heat, controller controls actuator and starts and can drive blade rotation, the rotation of blade is utilized to produce air-flow, to dispel the heat to outdoor heat exchanger.
S32: as Vt >=V0, controller controls actuator and cuts out.When the flow velocity Vt of the air-flow that anemobiagraph detects is more than or equal to the preset value V0 of air-flow velocity, can think that the flow velocity of now natural wind has been enough to the work for the outdoor heat exchanger heat radiation in housing, controller controls actuator and cuts out the rotation that can stop blade, natural wind is utilized to dispel the heat to outdoor heat exchanger etc., thus complete machine power can not only be reduced, and electric energy can be saved.
According to the control method of the air-conditioner outdoor unit of the embodiment of the present invention, make the unlimited direction of air inlet relative with air current flow direction by adjusting the second base, and detect the flow velocity of air-flow, when the flow velocity of air-flow is less than preset value, controller control and drive system driven vane is rotated, utilize the rotation of blade to produce air-flow to dispel the heat for outdoor heat exchanger, and when the flow velocity of air-flow is more than or equal to preset value, controller control and drive system stops driven vane rotating, natural wind is utilized to dispel the heat for outdoor heat exchanger, thus can according to the startup of the blast velocity control blade of natural wind and stopping, not only can reduce the complete machine power of air-conditioner outdoor unit, and can electric energy be saved.
