For this reason, the airflow position of the louver 35 set by the user can be maintained at the maximum in the first blowing direction at the wind direction position PO, and the ceiling air current sticking phenomenon can be prevented!
- step S9 the air volume of the blower 4 is changed from the air volume L to the wind direction position PO of the louver 35.
- Change to the set airflow first airflow. That is, the air volume of the blower 4 is changed to the air volume L in steps S5 and S6, and the louver 35 is changed to the air volume L prior to the change of the wind direction position PO from the wind direction position PO to the wind direction position P4.
- the setting of the louver 35 when the wind direction position is the wind direction position PO is changed to the air volume (for example, air volume M or air volume H).
- the air volume of the blower 4 does not increase until it is returned to the position P4. Therefore, do not give a draft to the users in the room!
- the air volume L is formally changed from the air volume L to the air volume L in this step S9.
- the air volume of the blower 4 does not change substantially.
- step S4 processing when the user changes the setting of the wind direction position of the louver 35 via the remote controller 84 while the processing of step S4 is also performed in step S4 will be described.
- the wind direction position of the louver 35 When the command to change the wind direction to the wind direction P2 (the third blowing direction) is issued, the control to change the wind direction position of the louver 35 from the wind direction position PO to the wind direction position P4 is executed as it is. It is now possible to process to change from wind direction position P4 to wind direction position P2 without changing the wind direction position from wind direction position P4 to wind direction position PO.
- the wind direction position of the louver 35 is changed from the wind direction position PO to the wind direction position P4 until the wind direction position P4 force is changed to the wind direction position PO again. Even if a command is issued, the process goes through the process of changing from the wind direction position PO to the wind direction position P4.Therefore, the louver 35 is operated with the wind direction position PO set to the wind direction position PO. Even when the air flow sticking phenomenon occurs, the ceiling surface U force can be peeled by guiding the flow of the conditioned air that is blown out downward to the downward direction.
- the wind direction position force of the louver 35 is not changed from the wind direction position P4 to the wind direction position PO after the wind direction position PO is changed from the wind direction position PO to the wind direction position P4. Therefore, it is possible to improve the responsiveness to the setting change of the wind direction position of the louver 35.
- step S9 control is performed to change the air volume of the blower 4 from the set air volume (first air volume, for example, the air volume H) at the wind direction position PO to the air volume L (second air volume). If the command to change the air volume setting of the blower 4 to the air volume M (third air volume) is issued during the operation, the control to change the air volume of the fan 4 to the air volume H force air volume L is executed as it is.
- step S9 the air volume setting of the blower 4 can be changed to the air volume L force air volume M without changing the air volume L from the air volume L to the air volume H.
- the airflow position of the louver 35 is set between the airflow direction position PO and the airflow direction position P4, and again from the airflow direction position P4 to the airflow direction position PO. Even if a command to change the airflow is given, the process changes to the airflow H force airflow L, so that the user in the room can be surely not given a draft feeling.
- the air volume of the blower 4 is changed from the air volume H to the air volume L and then directly changed to the air volume L force and the air volume M without changing from the air volume L to the air volume H, the air volume of the fan 4 Responsiveness to setting changes can be improved.
- step S4 force is being processed in step S9
- step S9 even if the user changes the setting of the wind direction position of the louver 35 or the setting of the air volume of the blower 4 via the remote control 84.
- the air flow blown out from the air outlet 32 is guided downward, the ceiling surface U force is peeled off, and the air flow of the blower 4 is reduced so as not to give a draft to the user in the room. You can do it.
- the air volume L which is the lower limit of the air volume that can be set by the user via the remote controller 84, is set in steps S4 and S5.
- the air volume 1 may be changed to an air volume LL having a smaller air volume than the air volume L set in a control manner when the air conditioner 1 is in a standby operation or the like.
- step S6 after the command to change the air volume of the blower 4, the force that waits for the elapse of the second predetermined time T2 When the response of the rotational speed control of the blower 4 is fast Since it is not necessary to wait for the second predetermined time T2 to elapse, step S6 may be omitted. [0036] (C)
- condition of the wind direction position of the louver 35 that activates the ceiling airflow sticking prevention control is set only when the state of the wind direction position PO continues for the first predetermined time or more. In order to prevent this, the condition of the wind direction position PO and P1 may continue as long as the first specified time!
- step S7 the wind direction position of the louver 35 is set downward from the wind direction position PO to the wind direction position P4.
- the ceiling airflow sticking phenomenon can be prevented, from the wind direction position PO. You may make it face down to wind direction position P3, which is higher than wind direction position P4.
- the present invention is applied to a four-way blow-out type ceiling-embedded air conditioner, but may be applied to other ceiling-embedded air-conditioning apparatuses such as a two-way blow-out type.
- the flow of the air-conditioning air blown out by the blowout force due to the disturbance to the airflow distribution in the air conditioning space such as the opening of a door or window is stretched on the ceiling surface. It can be prevented from sticking.
