| So far, the most of research on radiant floor heating system was conducted in steady state conditions of the floor radiator. However, in real conditions, radiant floor heating systems are subjected to different kind of thermal or hydraulic forcing. Thereby, experimental research of the massive floor radiator in the semitechnical scale in dynamic conditions is performed. The investigated floor radiator was subjected to thermal and hydraulic forcing, which appear during regulation processes of this type of heating systems. Heat transfer coefficients in the radiation way alpha(R) = 5.45-5.81 Wm(-2) K-1 and convection alpha(K) = 2.77-3.48 Wm(-2) K-1 and also the total heat transfer coefficient alpha(total) = 8.77-9.95 Wm(-2) K-1 from the surface of the massive floor radiator for the heating function of rooms were calculated. The difference (above 13%) between the value of total heat transfer coefficient from the surface of floor radiator, which was received in experimental way, and the value calculated by use of universally applied equation by design of radiant floor heating panel was noticed. |
