A STUDY ON DEW CONDENSATION RISK EVALUATION FOR COMMERCIAL BUILDING

Dew Condensation Risk Evaluation by Different Airtightness and Different Thermal Insulation Property

Abstract

 In this study, as the prerequisites for countermeasure of the dew condensation, in order to identify locations and frequency of dew condensation, the estimation of dew condensation on all wall and window in commercial buildings was conducted by TRNSYS simulation coupled with TRNFLOW. The airtightness and the thermal insulation property affect on dew condensation, accordingly the dew condensation risk evaluation with different airtightness and different thermal insulation property was performed. The dew condensation risk was calculated by using dew condensation risk evaluation index proposed by the authors in previous studies.
