Under heating conditions, and when the human body 30 feels hot, the angle A between the third air guide blade 231 and the horizontal plane can be adjusted to a value range of 5 degrees to 45 degrees, and the angle between the first air guide blade of the first air guide plate and the horizontal plane can be adjusted so that the airflow form of the fresh air from the fresh air outlet 23 and the conditioned air from the first air conditioning outlet 21 is as follows Figure 5As shown, the supply air temperature felt by the human body 30 is lower than the air conditioning air temperature, and there is no longer a sense of heat; on the contrary, the value range of the angle A between the third air guide blade 231 and the horizontal plane is adjusted to 45 degrees to 90 degrees, and the angle between the first air guide blade of the first air guide plate and the horizontal plane is adjusted so that the airflow form of the fresh air coming out of the fresh air outlet 23 and the air conditioning air coming out of the first air conditioning outlet 21 is as follows Figure 4 As shown, the mixed supply air temperature felt by the human body 30 is higher than the fresh air temperature, and there is no longer a cold feeling.

The mixed air formed by the two is blown to the human body 30, so that the temperature of the mixed air felt by the human body 30 is lower than the temperature of the fresh air, and the human body 30 no longer feels hot. Under heating conditions, and when the human body 30 feels hot, the value range of the angle A between the third air guide blade 231 and the horizontal plane can be adjusted to -5 degrees to -20 degrees, and the angle between the second air guide blade of the second air guide plate and the horizontal plane can be adjusted so that the airflow form of the fresh air from the fresh air outlet 23 and the conditioned air from the second air conditioning outlet 22 is as follows.

[0048] When the distance between the human body 30 and the air-conditioning indoor unit is greater than 2m, in order to make the fresh air coming out of the fresh air outlet 23 be delivered to the human body 30, the conditioned air coming out of the first air-conditioning outlet 21 and the conditioned air coming out of the second air-conditioning outlet 22 work together to drive the fresh air coming out of the fresh air outlet 23 to supply air, it is necessary to set the value range of the angle A between the third air guide blade 231 of the third air guide plate at the fresh air outlet 23 and the horizontal plane to 5 degrees to 90 degrees, and adjust the angle between the first air guide blade of the first air guide plate and the horizontal plane and the angle between the second air guide blade of the second air guide plate and the horizontal plane to achieve the fresh air outlet 23. The fresh air coming out of 23 is delivered under the joint action of the conditioned air coming out of the first air-conditioning outlet 21 and the conditioned air coming out of the second air-conditioning outlet 22; further, under the cooling condition, and when the human body 30 feels cold, the value range of the angle A between the third air guide blade 231 and the horizontal plane can be adjusted to 5 degrees to 45 degrees, and the angle between the first air guide blade of the first air guide plate and the horizontal plane and the angle between the second air guide blade of the second air guide plate and the horizontal plane can be adjusted, so that the airflow form of the fresh air coming out of the fresh air outlet 23, the conditioned air coming out of the first air outlet 21 and the conditioned air coming out of the second air outlet 22 is as follows Figure 9As shown, the fresh air coming out of the fresh air outlet 23 increases the air supply distance of the fresh air only under the combined blowing force of the conditioned air coming out of the first air-conditioning outlet 21 and the conditioned air coming out of the second air-conditioning outlet 22, and the three are not completely mixed, which makes the fresh air coming out of the fresh air outlet 23 able to blow to the human body 30, while the conditioned air coming out of the first air-conditioning outlet 21 and the conditioned air coming out of the second air-conditioning outlet 22 are both blown to the area above the human body 30, so that the human body 30 can not only breathe fresh air, but also feel The supply air temperature is higher than the air conditioning air temperature, and there is no longer a cold feeling; on the contrary, when the human body 30 feels hot, the value range of the angle A between the third air guide blade 231 and the horizontal plane is adjusted to 45 degrees to 90 degrees, and the angle between the first air guide blade of the first air guide plate and the horizontal plane is adjusted, and the angle between the second air guide blade of the second air guide plate and the horizontal plane is adjusted, so that the airflow form of the fresh air coming out of the fresh air outlet 23, the air conditioning air coming out of the first air conditioning outlet 21 and the air conditioning air coming out of the second air conditioning outlet 22 is as follows Figure 8 As shown, the fresh air from the fresh air outlet 23 is mixed with the conditioned air from the first air conditioning outlet 21 and the conditioned air from the second air conditioning outlet 22 to form a jet air supply. The conditioned air from the first air conditioning outlet 21 and the conditioned air from the second air conditioning outlet 22 jointly drive the flow of the fresh air from the fresh air outlet 23. The mixed air formed by the three is blown to the human body 30, so that the temperature of the mixed air felt by the human body 30 is lower than the temperature of the fresh air, and the human body 30 no longer feels hot. Under heating conditions, and when the human body 30 feels hot, the value range of the angle A between the third air guide blade 231 and the horizontal plane can be adjusted to 5 degrees to 45 degrees, and the angle between the first air guide blade of the first air guide plate and the horizontal plane and the angle between the second air guide blade of the second air guide plate and the horizontal plane can be adjusted so that the airflow form of the fresh air from the fresh air outlet 23, the conditioned air from the first air conditioning outlet 21, and the conditioned air from the second air conditioning outlet 22 is as shown. Figure 9 As shown, the supply air temperature felt by the human body 30 is lower than the air conditioning air temperature, and the human body 30 no longer feels hot; on the contrary, when the human body 30 feels cold, the value range of the angle A between the third air guide blade 231 and the horizontal plane is adjusted to 45 degrees to 90 degrees, and the angle between the first air guide blade of the first air guide plate and the horizontal plane is adjusted, and the angle between the second air guide blade of the second air guide plate and the horizontal plane is adjusted, so that the airflow form of the fresh air coming out of the fresh air outlet 23, the air conditioning air coming out of the first air conditioning outlet 21 and the air conditioning air coming out of the second air conditioning outlet 22 is as follows Figure 8 As shown, the mixed supply air temperature felt by the human body 30 is higher than the fresh air temperature, and there is no longer a cold feeling.
