In summary, the air conditioning system can meet a variety of air outlet requirements:

a) Please refer to Figure 5. In order to make the air outlet speed of the air conditioner faster and the air volume to gather, so that the air outlet of the air conditioner can spread farther (that is, the air supply distance is long), so as to speed up the indoor air flow and achieve the purpose of rapid temperature adjustment, Then the air guide member 1 can be rotated at an appropriate angle to reach the first working position. At this time, the first opening of the radial air outlet (that is, the large opening with a larger flow cross-sectional area) is the air inlet, which is located inside the main air conditioner and has a diameter of The second opening to the air outlet (that is, the small opening with a smaller flow cross-sectional area) is the air outlet, which is located on the inner side of the air conditioner. , because the cross-sectional area of the flow becomes gradually smaller, it has the effect of condensing and accelerating.

b) Refer to Figure 6, in order to slow down the air outlet speed of the air conditioner, avoid excessive air volume accumulation, and improve the user experience, the air guide member 1 can be rotated at an appropriate angle to reach the second working position. The first opening (that is, the large opening with a larger flow cross-sectional area) is the air outlet, which is located on the outside of the air conditioner, and the second opening of the radial air outlet (that is, the small opening with a smaller cross-sectional area) is the air inlet, which is located inside the air conditioner. , When the air conditioner is working, the air flow after temperature adjustment by the air conditioner enters from the second opening and is sent out from the first opening. Since the flow cross-sectional area gradually increases, it has the effect of dispersion and deceleration.

c) Please refer to Fig. 7, in order to further realize the breeze mode, the wind guide member 1 can be rotated by an appropriate angle to reach the third working position. At this time, the first opening and the second opening of the radial air outlet are rotated into the main unit of the air conditioner, and drain the air out of the air conditioner to the air conditioner panel 2 of the hollow structure, and supply the air through a plurality of air outlets on the outer layer 21 of the panel of the air conditioner panel 2, so as to realize the breeze mode and avoid the direct blow of the air conditioner. The problem of poor human improvement. Moreover, when the air conditioner is on standby or shut down and no air is needed, the air guide member 1 can also be rotated to the third working position. At this time, both the first opening and the second opening of the radial air outlet are transferred to the main air conditioner.
