Abstract

This current paper intends to present the modeling of heat exchange between the surrounding environment and heated concrete on the basis of the ”virtual tube” method and Lumped Capacitance Method. The method has been researched in the laboratory of Radiation Heating of the Faculty of Building Engineering of the Transilvania University of Brasov where the measurements have been taken. Within the study, it has been aimed at determining the values of the temperatures in different points of the surfaces and of the average temperature by the method of the virtual tube and with these parameters we have evaluated the quantity of heat absorbed by the heated concrete from the inner space. We intend to highlight in the paper that the solution of passive cooling of the rooms with the heated concrete system represents a solution with good results in buildings with a reduced cooling thermal load due to the judicious choice of the building materials which make up the envelop-opaque elements and glass surfaces and we bring into discussion the issue of heat releases by men who stay in during the day and which can greatly be absorbed by this passive cooling system.
