Abstract

Radiant heating and cooling systems can be utilized in association with renewable energy sources and are currently being used in newly constructed homes, as well as in buildings where heating and cooling systems have been converted from conventional systems to these systems. Thus, for a radiant system, the fundamental characteristic parameters, such as radiative, convective and total heat-transfer coefficients, carry the utmost importance. In the present study, these coefficients were determined through measurements from a test facility as well as numerical case studies.
