| Abstract |
In this study, as a method to reduce the energy consumption of the radiant floor heating system, the heating energy reduction was studied
using PCM, a latent heat storage device. A 44℃ PCM was installed under the heating pipe of the mock-up laboratory with the standard
floor structure applied, and the temperature change and energy consumption according to the PCM application were compared through the
experiment. For the experiment, two mock-up laboratories of the same standard were established outdoors. A general radiant floor heating
system and a PCM system were applied to each laboratory, and the indoor air temperature, floor surface temperature, heating hot water
temperature, and heating energy consumption were measured to compare the temperature change and energy consumption of each room. As a
result of the experiment, when PCM was applied, both the time to reach the maximum temperature from the start of heating operation
decreased in the case of indoor air temperature and floor surface temperature. As a result of comparison of hot water temperature, it was
confirmed that when PCM was applied, heating was operated for a shorter time, and heating energy consumption was also reduced. |
