| Abstract |
This study is Experimental Measurement of Heating performance, Energy Consumption and floor impact noise in Floor Heating Method of Construction by Using Ondol Panel of Double Metal Rendering. For this one, an experiment tests producing an each test speciment and measuring performance heating and noise. The result is proved as hot-water supply temperature as 45 ℃, maximum temperature about surface of mortar and air space in case of supply for 8 hours, mortar surface that is as 49.4 ℃, the gap of piping on center of mortar surface 44.1 ℃ and air space 25.3 ℃. Also, these is proved as a temperature of hot-water supply 75 ℃, hot-water supplying or circulating for 8 hours, as a technical development on mortar surface that is superstructure plumbing 51.8 ℃, the gap of piping on center of mortar surface 46.6 ℃ and air space 25.3 ℃. On the other hand, in floor heating structure, mortar surface is 48.8 ℃, the gap of piping on center of mortar surface as 41.4 ℃, air space is 25.7 ℃. In addition, the measurement is identified by hot-water supply is 45℃ and supply heating time for 4 hours, 4,646 kcal in technical development, 4,814 kcal in standards in floor heating system structure, 75℃ in hot-water supply, accumulating energy consumption of test speciment 1 is 5,643 kcal in case of heating and 5,860 kcal on standards in floor heating system structure. Also, the result of an experiment on other test-place in regard to between existing technology and developed technology of floor impact noise, sound pressure level in parts of center frequency and evaluating the figure by this test, existing technology are light-weight is 55dB, heavy-weight is 50dB and developed technology are light-weight is 48dB, heavy-weight is 46dB, is verified. |
