An Experimental Study on the Heat Transfer Characteristics of a Radiant Cooled Floor

Abstract

Radiant heating/cooling systems are being important and preferable due to their extensive usage area and energy saving status. Many kinds of energy generation systems can be utilized to supply energy for heating systems, such as renewable energy systems. As a result of these advantages, research over radiant heating and cooling in various sub-areas have remarkably increased in last decades, particularly with regard to obtaining the most suitable heat transfer characteristics for the use in building simulation programs, dimensioning, and designing. This study presents the heat transfer characteristics over a radiant cooled floor under the experimental conditions as of 3 different supply water temperatures of 10 o C, 15 o C, and 20 o C with supply water flow rates as 0.056 and 0,125 kg/s. The experimental results are compared with relevant literature and heat transfer coefficients are recommended.
