Why is the lower berth hot and the upper berth cold in bunk bed?

This is because the air expands and rises when heated, and the cold air contracts and sinks, so it will form a situation in which the upper shop is hot and the lower shop is cold.

Warm air is lighter than cold air, so warm air is concentrated near the air outlet of the air conditioner, that is, above the room, resulting in uneven heating, which is not conducive to the drying and dehumidification of the room.

In addition, when heating, the air outlet of the air conditioner is upward, which is easy to cause the loss of indoor heating, and the direct consequence is that the human body does not feel the temperature. Solution: The warm air is upward and the cold air is downward when the air conditioner is heating, so the air outlet of the air conditioner should be downward when heating.
