Thereafter, the wall surface W2 (see FIG. 8) facing the indoor unit 1 from the ceiling wall S due to the Coanda effect, the floor surface F (see FIG. 8), and the wall surface W1 on the indoor unit 1 side sequentially circulate and circulate. Therefore, it is possible to prevent the user from feeling cold because the conditioned air that has not been sufficiently heated at the start of the heating operation by the first airflow control does not directly hit the user.
- the second airflow control is performed by the control unit 60 when a certain period of time has elapsed after the heating operation is started or when the indoor heat exchanger 9 is sufficiently heated.
- the wind direction variable portions 113a, 113b, and 113c are arranged, and the conditioned air is sent at a wind speed of about 6 to 7 mZsec, for example, at the rear of the outlet 5 force.
- the wind direction variable unit 113a is disposed at a position where one end thereof comes into contact with the upper wall of the air flow path 6 to extend the upper wall of the air flow path 6 by driving the drive motor with the flat side facing the front.
- the other end of the wind direction variable portion 113a is disposed downward so as to be in contact with the rotation shaft 113e.
- the wind direction variable section 113b is arranged such that the tip is directed rearward and downward so that the blow path 6 side is concave.
- the wind direction variable section 113c is disposed with its tip directed rearward and downward so that the blow path 6 side is convex.
- FIG. 7 shows the static pressure distribution of the air passage 6 at this time.
- a high static pressure portion 90 that is higher than the static pressure of the front guide portion 6a is formed on the inner surface side of the wind direction variable portions 113a and 113b in contact with the wind direction variable portions 113a and 113b.
- the position of the wind direction variable units 113a, 113b, and 113c is adjusted according to the detection result of the static pressure detection sensor (not shown) that detects the static pressure of the blowing path 6, and the equal pressure line 90a of the high static pressure unit 90 is changed in the wind direction variable unit 113a. , 113b along the airflow circulating. That is, the high static pressure section 90
- the isobar 90a is formed substantially parallel to a line connecting the end of the front guide portion 6a and the end of the wind direction variable portion 113b, and the air flow is substantially parallel to the isobar 90a near the high static pressure portion 90.
- the high-pressure section 90 acts as a hydrodynamic wall surface, and the wind direction variable sections 113a, 113b, and 113c smoothly change the sending direction of the conditioned air to curve the airflow. Further, the isobar 90a of the high static pressure portion 90 in contact with the wind direction variable portions 113a and 113b does not intersect with the mainstream streamline of the airflow circulating through the airflow path 6. For this reason, the pressure loss exerted on the airflow can be significantly reduced.
- the arrangement of the wind direction variable units 113a, 113b, 113c is changed using the static pressure detection sensor so that the static pressure near the wind direction variable units 113a, 113b becomes a predetermined value.
- the positions of 113b and 113c may be stored as a database. As a result, data corresponding to the operating conditions can be retrieved from the database and the wind direction variable units 113a, 113b, 113c can be arranged at predetermined positions, and the static pressure detection sensor can be omitted.
- the main flow of the conditioned air flowing toward the variable wind direction units 113a, 113b, 113c flows through the space surrounded by the high static pressure unit 90 and the lower wall surface of the ventilation path 6. That is, the wall surface of the flow path is formed by the high static pressure portion 90. Therefore, since the airflow is not in contact with the wind direction variable portions 113a and 113b, loss due to viscosity is reduced, and the airflow can be further increased.
- the high static pressure portion 90 forms the wall surface of the flow passage, and the high static pressure portion 90 narrows the flow passage of the conditioned air to form a nozzle shape, so that the flow passage area is larger than that of the front guide portion 6a. Narrows. For this reason, the fluid of high energy is sent out from the outlet 5 by the action of the nozzle. As a result, the wind speed of the air flow adjacent to the high static pressure portion 90 does not change significantly, and the static pressure fluctuation of the air flow is suppressed, so that the air flow flows more smoothly and the pressure loss can be further reduced. Therefore, the air volume of the conditioned air sent from the air conditioner can be further increased.
- the flow path area narrowed at one end by the high static pressure portion 90 is enlarged again downstream of the wind direction variable portions 113a, 113b, and 113c. As a result, the flow path becomes more downstream.
- the cross-sectional area is reduced to form a minimum cross-sectional area portion (hereinafter referred to as "throat portion"). Therefore, a so-called diffuser is formed by the expanded flow path, and the static pressure of the blower fan 7 can be increased to further increase the air volume.
- the high static pressure portion 90 does not occur in the throat of the flow path and no pressure loss occurs, the flow path is bent at that position, so that a curved portion where no pressure loss occurs is formed. Can be formed.
- the wind direction variable portion 113b is arranged so as to intersect with a virtual surface 98 that extends the lower wall of the front guide portion 6a further outward of the outlet 5.
- the lower end of the wind direction variable portion 113a is disposed below the virtual surface 98, and the airflow is reliably guided backward and downward. Therefore, an unintended airflow is not sent in the direction, and a highly reliable air conditioner can be obtained.
- FIG. 8 shows the behavior of the airflow in the room R at the time of downward rear blowing.
- the conditioned air descends along the side wall W1 and travels down the floor F, the side wall W2 facing the side wall W1, and the ceiling wall S in order as shown by the arrow C, and returns to the suction port 4.
- the interior of the living room R is in a rising state in which the room temperature quickly rises and rises.
- the temperature is low enough that the user feels cold when the air sent from the indoor unit 1 directly hits. For this reason, the room temperature rises when performing the first airflow control, but the rising speed is slowing down. In the start-up state, the temperature reaches a temperature at which the user does not feel cold even when the air sent from the indoor unit 1 is directly hit, the room temperature is lower than the set temperature, and the state power quickly rises.

Therefore, there is no occurrence of a warm air pool E (see FIG. 30) in which the area around the indoor unit 1 is excessively heated, and the temperature near the suction port 4 is about the same as the set temperature of 28 ° C. Accordingly, the air conditioning efficiency is improved, and it is possible to easily determine whether or not the room is sufficiently warmed up!

- the blowing rate gradually decreases to about 70% at the same wind speed for the second airflow control.
- the conditioned air (warm air) sent rearward and downward from the indoor unit 1 does not roll up due to the Coanda effect and continues to descend along the side wall W1 to directly enter the living space. It does not get down and follows the floor F to reach your feet.
- the warm air does not reach every corner of the living room R, such as the boundary region between the side wall W2 and the floor F! Fear Therefore, it is more desirable to maintain the wind speed.
- the air The conditioner shifts to the start-up state and performs the second airflow control. Then, the third airflow control is performed when a certain time has elapsed or when it is detected that the temperature difference between the room temperature and the set temperature has become small. This is repeated to perform the heating operation.
