GENERATION OF NATURAL CONVECTIVE AIR FLOWS IN ROOMS WITH THE USE OF IN-FLOOR CONVECTORS WITH NATURAL CIRCULATION

Viktor Pukhkal, Vadim Bulgakov

Abstract


To prevent the intake of downward cold air flow from translucent structures into the room serving area, convectors with natural convection, embedded in floor construction, are used.
Convector operation was simulated at various distances from the glazing to the convector with ANSYS Fluent 14.5 program. Temperature and velocity fields inside the room were determined.
Natural convective flows in the room (downward cold air flow at the glazing and upward warm air from the convector) were described. Application conditions of in-floor convectors with natural air circulation were determined.
