- Abstract
- Preliminary tests have shown the existence of a "discomfort index", a function firstly of the difference between the temperature in the room and the temperature of the air current and, secondly of the speed of the air stream. The permissible limit for this index has been fixed at two degrees C., at least in that part of the room situated more than 20 cm. from the outside walls and less than two meters in height. Systematic artificial tests have resulted in satisfactory solutions being found for the air inlets into the outside walls. An elongated aperture placed above a radiator and fitted with a deflector so that cold air entering the room mingles with the ascending warm air current. An aperture located behind a convector heater so that the same result is achieved as in the case of the radiator. A row of apertures located along the heated ceiling placed so that entering air is diffused into the warm air before reaching the occupied zone. Some calculations aimed at determining the orders of magnitude of the necessary sections and the possible force of the air current in a high wind, have revealed the need for a manual or an automatic regulator where a wall is exposed to wind.
