Abstract

In recent
years, radiant heating systems have been catching more observation under favor
of the many advantages such as; energy saving and thermal comfort. However,
owing the fact that limited information on the system dynamics and the heat
transfer characteristics of radiant systems, conventional systems are still
preferred to radiant systems. Thereupon, radiant ceiling and floor systems are
favored to wall systems. Also previous researchers have focused on radiant
ceiling and floor systems instead of radiant wall systems. For this reason, a
controlled climatic test set-up was built and detailed examinations were
conducted. In this regard, to evaluate the heat transfer coefficients of the
radiant wall panels, 10 different test cases were run using different supply
water temperatures.
On the basis of the
obtained measurements, in the steady state, heat transfer coefficients,
depending on the characteristic temperature differences and the heat transfer
rates have been calculated. According to the results, the approximate mean
values of 2.40, 5.49 and 8.29 W/m2K were evaluated, respectively for
the convective, radiant and total heat transfer coefficients of radiant wall
heating systems.
