Abstract

We report in this paper the thermal comfort and energy saving potential of a decoupled ceiling radiant cooling panel (DCRCP), which is an infrared transparent and high resistance layer to separate cooling surface and air-contact surface. A CFD model was built for a DCRCP when it was installed inside a thermal chamber. Firstly, the thermal comfort was investigated when the DCRCP used different radiant panel surface temperatures. Results indicated that the thermal comfort of the DCRCP satisfied the PMV and PPD criteria of the ASHRAE Standard55-2017. Secondly, the energy saving potential of the DCRCP was studied using the same thermal chamber when inter walls were given different emissivity. Compared with commonly used wall emissivity, the energy saving potential of the DCRCP achieved ~ 8.4% as the emissivity is low as 0.1. It was suggested that low radiant panel surface temperature and low wall emissivity could improve the energy saving potential. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2023.
