Radiant panels for heating and cooling are becoming very popular, both in dwellings and in office buildings. In fact they guarantee not only thermal and acoustic comfort but also good energy efficiency due to favourable working temperatures. Such temperatures fit the exploitation of geothermal heat pumps and solar thermal panels, so low temperature difference radiant systems make it possible to increase energy efficiency in buildings. The detailed analysis of thermal performances of radiant panels requires the study of heat flows involving each internal surface of the test room. In this work a climatic room (with radiant panels installed in all surfaces) has been equipped and studied for cooling capacity rating according to standard EN 14240. In addition to the cooling capacity, also heating capacity performances have been investigated by means of tests, adapting the Standard for such a target.

Abstract

Radiant panels for heating and cooling are becoming very popular, both in dwellings and in office buildings. In fact they guarantee not only thermal and acoustic comfort but also good energy efficiency due to favourable working temperatures. Such temperatures fit the exploitation of geothermal heat pumps and solar thermal panels, so low temperature difference radiant systems make it possible to increase energy efficiency in buildings. The detailed analysis of thermal performances of radiant panels requires the study of heat flows involving each internal surface of the test room. In this work a climatic room (with radiant panels installed in all surfaces) has been equipped and studied for cooling capacity rating according to standard EN 14240. In addition to the cooling capacity, also heating capacity performances have been investigated by means of tests, adapting the Standard for such a target. Moreover, this study examines radiant and convective thermal loads effects on the global thermal environment.
