Radiant Cooled Floors— Operation and Control Dependant upon Solar Radiation

摘要

Radiant cooled floors have been successfully used on many projects over the past ten years, and many ASHRAE and other peer-reviewed papers have been written on these projects. However, many questions still arise regarding the performance of radiant cooled floors when subjected to solar radiation. The convective cooling performance of a cooled floor has been reported by Olesen (1994) and Simmonds (1994); Borressen (1994) reported on the solar absorption of a radiant cooled floor, which was further reported by Simmonds, Gaw, Hoist and Reuss (2000). Even with this research, many questions are still being raised regarding the performance of a radiant cooled floor when absorbing solar radiation. This paper explains the performance of the floor, including some limitations of the presentedcalculation method and information on controllability.
