| Abstract |
From the viewpoint of the indoor temperature distribution and the indoor comfort of thermal environment, this study investigates the heating characteristics of electric hot air heating system with thermal storage using off-peak electricity and floor electric panel heating system without thermal storage. From this study, it was observed that the electric hot air heating system with thermal storage exhibits more temperature difference between the top and bottom in the space than the floor electric panel heating system without thermal storage. And the former system has advantages that it is more superior in the indoor thermal environment in spite of a little deterioration of indoor temperature??at the end of the heating and is more economic than the latter system, and is able to control the deterioration of indoor temperature during off-heating. It was confirmed that the floor electric panel heating system without thermal storage requires a long time to reach the stable indoor temperature after the beginning of the heating, and can keep a constant indoor temperature and improve the indoor comfort. |
