Heating pipes burst was occurred in the apartment complex that was applied floor radiant heating system. There were two opinions for the cause of the bursted heating pipes that was the flaw during construction and defects in the product and also there were conflicting among them. Officials analyzed it in order to investigate the cause of the rupture. Tensile test results showed different tensile strength between the lower part of heating pipe and the upper part of heating pipes. The lower tensile strength is maintained while the top was not secured. The reason why rupture heating pipes is that flow velocity isn't secured and then the air get stagnant. Stagnant air makes hardening. It is caused rupturing. The proper flow rate was confirmed 0.166 m/sec after experiment. It isn't make stagnant air inside heating pipes.

본 연구의 목적은 아파트 공간에 남아 있는 한국의 전통 실내공간 및 구성 요소를 조사해보는 것이다. 이를 위해 관련문헌을 고찰하고 52가구의 아파트를 선정하여 방문에 의한 설문조사와 현장조사를 하였으며 그 결과는 다음과 같다. 첫째, 공간의 배치 및 구성은 현관-거실 및 식당-방-안방의 서양적 평면보다 현관-방-거실 및 식당-안방의 한국전통공간에서 기인한 평면이 선호되었다. 둘째, 공간의 특성은 한국 전통공간의 여러 특성 중 거실-방, 거실-식당, 식당-부엌 사이의 공간 디자인에서 개방성과 폐쇄성을 찾아볼 수 있었다. 셋째, 난방의 종류는 전체 라지에타 방식에서 전체 바닥 난방으로 변화하였다. 또한 공간구성 요 소 중에서 바닥은 온돌마루와 장판이, 벽은 벽지가, 천장은 방에는 평 천장, 거실에는 가운데가 매립된 천장이 선호되었고, 창문은 특히 안방의 경우 전통적 창살 문양을 선호하였다

The purpose of this study is to develop the new korean district heating system for apartment houses. The upper & lower side ondol system with multi sensing control system was developed as a new korean district heating system and evaluated in 2 mock-up laboratories last winter. As a result of field measurement, when the load differences between perimeter zone and central zone are increased, the ondol system divided in the upper and lower side can be evaluated as the new ondol system with a capability for suppling proper heating energy for each zone. The user can have the freedom for changing an upper zone and a lower zone and controlling each temperature according to their needs.

Recently developed raised floor heating system is not only capable of basic function to reduce noise between floors, but also is a multi-functional floor heating system enabling natural ventilation. The procedure of this system for natural ventilation is to import outdoor air through bottom space of the floor heating system, circulate indoor space and discharge it out of ceiling. In winter, powerless natural ventilation is possible with buoyancy effect caused by temperature difference between outdoor and indoor. And it also allows saving of energy by importing pre-heated air in bottom space of the floor heating system. To evaluate ventilation performance of this system, on-site measurement was conducted in 2 test laboratories, and the nominal air change rate was satisfied as 0.4$\sim$0.8 h-1 under the condition of outdoor temperature $5^{\circ}C{\sim}-5^{\circ}C$, which was evaluated as highly possible to be applied as a natural ventilation system in multi-family houses.

Korea which has change of clear season is using unique heater by the name of On-dol being invented since ancient times. Floor-heating device has no radiator, and generates no noise and dust. It can obtain satisfied heating sense than other heating system in low room temperature. And also it is a pleasant system that equals bottom and top temperature in a room. The purpose of this study is to develop the Floor-heating device using pulsating heat pipe. It propose floor-heating device using pulsating heat pipe of the dry process which alternative polyethylene pipe(low XL pipe) that is used widely to existent floor heating system and produce pilot Experiment and analyzed operation condition and performance of most suitable. In this study, main purpose is to develop floor-heating system using pulsating heat pipe by finding an optimum working condition according to changing ratio and evaluating a performance.

The traditional Korean heating system ondol, one of the most important characteristics of Korean architecture, still remains as hydronic floor heating. Various studies have been conducted on the modernization of ondol, but the process of introducing the hydronic floor heating has not been seriously studied so far. Therefore, this paper aims to demonstrate how the hydronic floor heating had been introduced to Korea, taking the 1950s and 1960s Haengchon, Jongam, and Mapo Apartments for example - these three are regarded as the first Korean apartment houses after the Korean War. While Western advanced construction technology was imported for these apartments, various methods of modernizing ondol were also considered. What was remarkable in these attempts is that hydronic floor heating first appeared in Mapo 1st Apartment in 1962, because this is the universal heating method in the present Korea. This fact signifies that the traditional principle of floor heating has been maintained, and it would also be meaningful in terms of architectural exchanges between East and West, if considered along with Wright's application of the Korean heating principle to his houses since 1930s.
