ABSTRACT

Modern buildings require energy-efficient heating and cooling method for the both parts of the system, the heating/cooling source and the heating/cooling distribution system. Modern heating and cooling systems typically combine a reversible heat pump with a low temperature radiant system. Thermally activated building systems (TABS) use the large thermal mass of concrete from building structure as a buffer for lowering the cooling and heating loads during the day. In this paper we illustrate the floor covering influence in heating mode, over an experimental thermally activated building floor. TABS can be used for both heating and cooling. The experimental model is placed in the Radiant Surfaces Laboratory, in the basement of the Faculty of Civil Engineering from Brasov, Romania. The heating source for the experimental model is a 6kW vapor compression heat pump placed in the Heat Pump Laboratory, on the ground floor of the faculty. We used in this experiment four types of floor covering: tiles, parquet, PVC carpet and linoleum. Results show that the highest surface temperature is obtained with ceramic tiles as floor covering.
