Effect of Combined Heat and Moisture Transfer on the Predicted Indoor Thermal Environment

Abstract

Both building performance and occupants' thermal comfort are influenced by heat conduction, convection and radiation as well as condensation/evapora tion. This paper presents an analysis of thermal comfort in buildings subjected to simultaneous heat and moisture transfer using numerical techniques. A model based on computational fluid dynamics has been developed for predict ing the indoor thermal environment. Assessment is made of the effects of radiation heat transfer and moisture condensation on the accuracy of pre dicted indoor thermal comfort.
