Abstract
The study describes an experimental and simulation study to estimate load handling capacity and thermal performance of radiant cooling system installed in existing building in India. To evaluate thermal performance and capacity, experiments are conducted and simulations were carried out using EnergyPlus tool. Building model was calibrated using the experimental results and a parametric analysis at different operating condition has been done on calibrated model. The result shows that ceiling radiant cooling panel can handle up to 25 W/m2to 72 W/m2, at supply water temperature of 15°C and 20°C respectively. These results are also validated by evaluating the characteristic performance exponent (nco’’) given in ASHRAE Standard 138.
