Abstract

In the tropics, air-conditioning in buildings is highly energy-intensive. Radiant cooling is considered to be a potential means to conserve energy from air-conditioning. This paper presents results of an experimental and simulation study on application of a radiant cooling system in tropical Thailand. The system used radiant cooling panels to extract sensible heat from the experimental room. Heat pipe run around-coil heat recovery was used to handle the latent load from ventilation air and enhance its performance. By modeling the system using TRNSYS program, the simulations show that the radiant cooling system can save energy high upto 19 percent compared to the conventional air conditioning system.
