Korea residential housing generally use wet floor heating system 'Ondol' which consist of insulation cushioning, lightweight foamed concrete, hot water pipe and mortar on top of reinforced concrete slab. Wet floor heating system's installation process is too complicate and difficult to supervise field for continuing assurance quality. Also, this method has a huge impact on the progress of construction because it take a long time to cure finishing mortar and lightweight foamed concrete. Therefore, it is considered a disturbance factor of reduction of construction duration for enhancing competitiveness. In this study, we conducted an experiment about the radiant heat performance and temperature difference on upper panel of rolled dry floor heating systems which is jointly developed by Kolon global and Sumisho Metalex for remodeling housing, studio apartment and the urban-life housing.

The present study conducted comparative evaluation of wet dry floor heating systems using geothermal heat pump. Circulation hot water from geothermal heat pump which is $10{\sim}15^{\circ}C$ lower than that from boiler was used. In order to access indoor temperature ($25^{\circ}C$) it took 74 minutes for dry type and 247 minutes for wet type. Average floor temperature was $23.89^{\circ}C$ for wet type and $32.66^{\circ}C$ for dry type. Energy saving rate gradually increased by 66% after 138 minutes. In the results, for floor heating system using low temperature circulation water, wet type was not enough to meet stable and comfortable radiant floor heating due to low floor temperature and access time to indoor set temperature. While dry type was practicable for stable floor heating due to fast rise of indoor set temperature and comfortable floor temperature.

The present study was conducted for a comparative evaluation of wet and dry floor heating systems using geothermal heat pump. We circulated hot water from geothermal heat pump which is $10{\sim}15^{\circ}C$ lower than that from boiler. In order to access indoor temperature ($25^{\circ}C$) it took 74 minutes for dry type and 247 minutes for wet type. Average floor temperature was $23.9^{\circ}C$ for wet type and $32.7^{\circ}C$ for dry type. Energy saving rate gradually increased by 66% after 138 minutes. As a result, in case of floor heating system using low temperature circulation water, dry type was more practicable for stable floor heating than wet type in terms of floor temperature and access time to indoor set temperature.

정부의 주택 2백만호 건설이 본격 추진되면서 건설인력난, 자재난 등이 심화되고 있어 설비공사업계가 이의 대책 마련의 일환으로 건식공법 개발에 부심한 노력을 기울이고 있다. 건식 공법은 자재의 대량생산으로 현장에서 조립만 하면 되기 때문에 시공이 간편할 뿐만 아니라 비숙련공도 거뜬히 시공할 수 있어 인건비 및 자재난 등을 해결할 수 있다. 게다가 건설공사에 있어서 가장 중요한 공사비 절감, 공기 단축, 품질의 표준화 등의 효과를 누릴 수 있기 때문에 설비공사업계에선 이의 적극적인 도입이 더욱 필요한 때이다.
