| 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. |
