Determination of the Chilled Water Temperature and Flow Rate of the Radiant Floor Cooling System in Residential Buildings

摘要

This study aims to derive design data of the supply chilled water temperature and water flow rate for the radiant floor cooling system in Korean residential buildings. At first, prEN-1264 standard and ASHRAE method for the radiant floor cooling system design were reviewed. Secondly, to verify application of the standard, mock-up tests were performed. The results show that prEN-1264 method is appropriate in case supply chilled water temperature is low. By using calculation method presented in prEN-1264 standard, design data for Korean residential buildings was derived. This study would be able to determine the supply chilled water temperature and water flow rate in design process.
