A Study on the Thermal Performance Improvement of Prefab-ONDOL System by Numerical Simulation |
| Abstract |
This study aims to offer the basic data which can improve the thermal performance of the Prefab-ONDOL system by the thermal analysis.A computer simulation program to predict the Unsteady-state heat transfer of the Prefab-ONDOL system was developed andvalidated with model tests.The results of this study are as follows.1)In A model, it needs more thermal mass for effective utilization in intermittent heating method.2)In B model, the continuous heating method is more effective than the intermittent heating method.3)In C model, the melting point temperature of PCM (29.5C)is low for offering comfortable condition. We suggest that the development of PCM whose melting point temperature is about 34.5 should be needed. |
