Abstract

This paper describes an experimental and simulation study to estimate the load handling capacity and thermal performance of a radiant cooling system installed in an existing building in India. To evaluate capacity and thermal performance, experiments were conducted and simulations were carried out using the EnergyPlus (DOE 2015) building energy modeling tool. A building model was developed and calibrated using the experimental results. The calibrated model was then used to perform a parametric analysis at different operating conditions. The results show that ceiling radiant cooling panels can handle cooling capacities of 25 to 72 W/m2 (7.92 to 22.82 Btu/h·ft2)at supply water temperatures of 15° C to 20° C (59° F to 68° F) respectively. These results were also validated by evaluating the characteristic performance exponent (nco") given in ANSI/ASHRAE Standard 138.
