Abstract

This study in which a phase change material (PCM) was applied to a general floor heating system, and the temperature change according to the insertion location was confirmed. Most apartment houses in Korea use a floor heating system using hot water. Since such a floor structure has difficulty in securing sufficient heat capacity due to structural constraints, it is necessary to develop a new floor heating system with improved heat storage performance. Accordingly, the PCM insertion location and heating schedule were introduced and tested in the PCM-applied floor heating system with improved heat storage performance. As a result of the experiment, when the heating was stopped for 30 minutes and 3 hours by inserting the PCM into the side, the indoor and surface temperature of Room 2, a floor heating system to which PCM was applied, was 1.6℃ and 1.5℃ lower than that of Room 1, a general floor heating system. At the time of 1 hour operation and 3 hour shutdown, the indoor and surface temperature of Room 2 was 1.0℃ and 0.9℃ lower than that of Room 1. When the PCM was inserted in the lower part and operated for 30 minutes, the surface and room temperature of Room 2 was 2.4℃ and 1.0℃ higher than that of Room 1, and 2.4℃ and 1.0℃ higher when operated for 1 hour. According to the experimental results, it was confirmed that in the floor heating system to which the PCM was applied, the surface and room temperatures were higher when the PCM was inserted in the lower part than in the side of the hot water pipe.
