A new liquid desiccant system for air-conditioned spaces with high latent and cooling loads.

Author(s) : YIN Y., ZHANG X., CHEN Q.

Summary

This paper proposed a new ventilation system with radiant cooling by using liquid desiccant dehumidification, which provided very dry supply air and chilled water for radiant cooling. The dry air was from liquid desiccant dehumidification process and the chilled water was produced by liquid desiccant evaporative chilling. This study used an office with a high latent load to demonstrate the application of such a system. 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 showed that the new system could reduce the risk of condensation on the cooling panels and offer a comfortable indoor environment. The new system has a great potential for use in hot and humid climate regions.
