Abstract
In a method for cooling rooms, the energy exchange between warm room air and cold air takes place through inherent convection of the air by means of a drop shaft arranged in the room, which has cooling surfaces in its upper part, at which the in-coming warm room air cools, and flows downwards owing to the specific weight difference. The cooled air leaves the drop shaft at the lower end in a laminar flow and then spreads in the room in an unbroken cool layer. The air leaving the drop shaft can also be deflected into a hollow floor. It is possible to use a fan to add to the cooled air current moved by gravity disturbing air, which then occasions turbulence.
