How do you use an electric fan to set up an air distribution system in an air tight room?
Turn the fan on the cabinet towards the window (the effect of a platoon fan is better than the fan you are now placing in the lower part) Then another fan from the end of the bed (though it may be your pillow) sends the air deep into the room to increase ventilation.
Use the height of the cabinet to supply air to the room, so as to push the air down the high side of the room, and then push the air toward the window in a lower position.
In the real and complex environment, to ensure a large enough opening is the most important, the main problem for a separate space at the same time, even if the opening is the same, as long as the height is large enough, will form a similar movement in the air above or under the calm wind
In contrast, outdoor, room because of the enclosure, radiation and heat inside the reasons, in most cases, the temperature will be higher than the outdoor level. In the temperature stratification under the condition of the same, because the overall warmer indoor air temperature smaller, resulting in a lesser level of indoor air pressure difference outside the same distance.
In the absence of outdoor airflow, the warm air is lighter than the cold air. From a hydrostatic point of view, the temperature difference brings air stratification in the vertical direction
