Even if your ankles are warm and warm, they won't dry out!

The "Nokuria X" series features side fans "Dual Blaster" on both sides. In the 2015 model, the size of the indoor unit has become compact with 786 x 378 x 293 mm (width x depth x height), and the design of the side fan has become integrated with the main body. Furthermore, since the outlet of the side fan is hidden when stopped, it has a neat and clean appearance that you can't even notice its existence at first glance.

That's why the side fans, which show their presence for the first time when they are driven, always make me happy because they always say, "Wow, that's amazing. Where's the air conditioner?"

How does such a side fan work during heating? The room temperature that day was 20°C, which wasn't that cold yet, so I set the temperature to a high 24°C. Immediately after the start of operation, it is in the so-called "preparation stage", and since warm air does not come out of the air outlet, the flap remains upward. When the heat exchanger works and warm air comes out, the flap of the central fan turns downward, and after a little delay, the side fans also turn downward and send out the air at the set room temperature.

Room temperature is 20℃, humidity is 57%, and in mid-November, in order to check the heating performance, we set the room temperature to 24℃, which is 4℃ higher than the room temperature. During heating operation, the flap does not turn downward until warm air is released at the start of operation.

Checking the setting status of the air direction of the central fan and side fan during heating "Comfortable Omakase Airflow" operation with the remote control As you can see, the center fan is one step above the bottom in the vertical direction, and slightly to the left in the horizontal direction. The side fans are set one level higher than the central fan in the vertical direction, and are set in almost the same direction in the horizontal direction.

After a while, the thermo-hygrometer hung diagonally from the air conditioner showed the set temperature of 24°C. Humidity has decreased by only 1%

I can understand because it is an iron rule that warm air blows downward as much as possible so that warm air does not go upward, but the left and right direction is not straight, and the room is Why is it set to the left to point towards the center? It's as if a camera is installed to see what's going on in the room even though it's left to you.

When I checked the initial setting screen of the remote control, I was able to easily solve the mystery. Yes, there is a screen that allows you to set the position in the room with the remote control. Usually, the person in charge of construction should do this when installing the air conditioner, but it is safe to check it once in case it happens. In this initial setting, ``the installation position is on the right side of the room'', so when operating with ``comfortable air flow'', warm air is sent to the center to create a comfortable air flow throughout the room. That's it.
