From the author: Radiant cooling has shown great advantages when it comes to improving thermal comfort and can also reduce energy demand. But the system may have a high condensation risk if used with a high latent load. This study proposes a new type of ventilation system that uses a radiant cooling panel and air supplied from a liquid desiccant dehumidification system, which provides very dry supply air and chilled water for radiant cooling. This study uses an office with a high latent load to demonstrate the application of such a system in a hot and humid climate. By using a validated computational fluid dynamics (CFD) program to calculate the distributions of air temperature, humidity, and velocity, as well as the predicted mean vote in the office, the results show that the new system could reduce the risk of condensation on the cooling panels and offer a comfortable indoor environment. The new system has great potential when it comes to use in hot and humid climate regions.
