The thermal output evaluation of radiant heating panels by experiment

Abstract

The purpose of this study is to make the target condition of experimental assessment based on the standard EN1264. To achieve this purpose, the characteristic errors, which are caused by characteristics of experimental setup and prevent the results from meeting the target condition, should be removed. This study proposes an experimental setup and suggests a control strategy based on standard EN1264. For the specifications of the experimental setup, the essential equipment and the configuration of the heat production system were deduced. For a proper control strategy, possible control strategies were derived by investigating the control-related factors such as reference points and control algorithms, and the most proper control strategy was validated by experimental assessment. Practical application: This study presents an experimental assessment to evaluate the thermal output of radiant floor heating systems based on the standard EN1264 referenced by ISO11855-2:2012. The proposed experimental assessment method will be able to supplement ISO11855-2:2012 and contribute to the development of thermally effective radiant heating panels. Therefore, it is expected that the results will be helpful to researchers for indoor environment, heating, ventilating, and air conditioning engineers, system manufacturers, and those who want to analyze the thermal output of radiant floor heating panels based on ISO 11855-2:2012.
