  • The thermal comfort of an indoor swimming pool is different from that of general indoor space because of the characteristics of large space and the wear conditions of swimmers. Dew condensation by humid air not only makes mold on the floor, wall and roof but also decreases the durability of buildings by penetrating into their structures. In this study, the characteristics of the flow field, the temperature field and the humidity distribution in an indoor swimming pool have been examined by the numerical method to estimate the level of thermal comfort and the generation rate of dew condensation. The results showed that the dew condensation regions were spread widely at the eastern parts of the swimming pool due to the insufficient air flow rate with low velocity and temperature. To prevent the generation of dew condensation in a region, a sufficient warm air flow rate should be supplied to make an air mixing. The values of PMV at horizontal plane of 1.5 m height have the range of -1.0∼1.2, which means the suitable level for swimmers.

  • Recently, in accordance with increase of the desire for Sports for All(Life Sports), the swimming pools in many areas are under construction. However, since they used many of the reflexible finish-materials on account of the characteristics of hydrophilic space, most of the Indoor Swimming Pools are generating the excessive reverberation. Such reverberation is bringing about the problem that obstructs the oral communication between the coach and the player, and the Clearness of Sound, besides the sport activity. On this viewpoint, on the object of the actually built indoor swimming pool, after the conduct of an optimized acoustics design by the remodeling through a computer simulation, and by carrying out the Psycho-Acoustics Experiment utilizing of Auralization Technique which is able to experience Virtual Sound Field at the stage of designing, then this thesis has attempted to appraise on the acoustic condition after the completion of construction. It is considered that such result of the study could be utilized as the useful data that enables to improve the curtailment effect of construction cost as well as the acoustic capability, by means of the presupposition control on the acoustic problem from the stage of design, for the occasion when the similar indoor swimming pool is planning to build, henceforth.

  • The objectives of this study were to evaluate the air quality surrounding an indoor swimming pool, to estimate the cancer risk based on the airborne exposure to trihalomethanes (THMs), and to examine the ventilation efficiency by Computational Fluid Dynamics (CFD). Chlorine and THMs were measured poolside, and in the staff room and reception area. The indoor swimming pool was modeled using the Airpak program, with ventilation drawings and actual survey data. Temperature, flow and mean age of the air were analyzed. Levels of chlorine poolside, and in the staff room, and reception area were $203\;{\mu}g/m^3$, $5\;{\mu}g/m^3$, and $10\;{\mu}g/m^3$, respectively. Chloroform was the dominant THM in all sampling sites and mean concentrations were $16.30\;{\mu}g/m^3$, $0.51\;{\mu}g/m^3$, and $0.06\;{\mu}g/m^3$ poolside, in the staff room and reception area, respectively. Bromodichloromethane and Dibromochloromethane levels were respectively estimated as $10.3\;{\mu}g/m^3$ and $1.7\;{\mu}g/m^3$ poolside, $1.3\;{\mu}g/m^3$ and $0.1\;{\mu}g/m^3$ in the staff room, and were not detected in the reception area. The cancer risks from inhalation exposure to THMs were estimated between $3.37{\times}10^{-7}$ and $1.84{\times}10^{-5}$. A short circulation phenomenon was observed from the supply air vents to the exhaust air vents located in the ceiling. A high temperature layer was formed within one meter of the ceiling, and a low temperature layer was formed under this layer due to the low velocity and high temperature of the supply air, and the improper locations of the supply air vents and exhaust air vents. The stagnation was evident at the above adult pool and the mean age of the air was 22 minutes. Disinfection by-products in the indoor swimming pool were present in higher concentrations than in the outdoor air. In order to increase the removal of pollutants, adjustment was required of the supply air volume and the supply/exhaust position.

  • This study is empirically intended to look into the effects of HVAC management on condensation cause and prevention in indoor swimming pools. The findings are summarized as follows. First, the experience of condensation in indoor swimming pools showed that 132 out of 142 people in total experienced the condensation in indoor swimming pools, which they had a high experience rate of 92.3%. For the location of condensation, the wall joints were 46.8% and the windows were 34.5%, which a total of 72.3% occurred in the wall joints and windows. Second, the effect of construction design, HVAC management and building construction on the cause of condensation in indoor swimming pools showed that building construction had an effect on the cause and location of condensation depending on the seasonal time, partially adopting hypothesis 1. Third, the effect of condensation-causing factors on condensation-preventing factors in indoor swimming pools showed that condensation had a close relationship with air and temperature conditions depending on the time and location of condensation, adopting hypothesis 2. As for the above-stated findings, the HVAC management in indoor swimming pools is an important concern factor that continues to cause condensation despite the development of advanced construction materials. Especially, building construction is a main factor that has a direct effect on condensation in the HVAC management of facilities. This implies that the window management is important in maintaining the wall joints - which can suppress the selective use and defect occurrence of construction materials - or confined spaces for a long time.

  • 염소처리된 수영장 물에는 염소처리된 음용수에 비해 높은 농도의 크로로포름이 존재한다.네 개의 수영장 (국내수영장 A,B 및 C 롸 미국 뉴저지주 수영장 D)물에서 클로로포름 농도를 조사하였다. 수영장 C(시관리)에서 측정된 클로로포름 농도는 개인 운영 수영장 A 와 B 에서 측정된 클로로포름 농도와 통계적으로 (p=0.0001) 다르게 나타났다 : 수영장 A, B, 및 C 에서 측정된 클로로포름 농도는 통계적으로(p=0.0001) 다르게 나타났따. 국내 수영장 물의 평균 농도와 농도 범위는 각가 23.$\mu\textrm{g}$/ㅣ 과 10.9-47.9$\mu\textrm{g}$/ㅣ 이며, 뉴저지주 수영장 물의 평균 농도와 농도 범위는 각각 64.4${\mu}g/l$ 과 27.-96${\mu}g/l$ 였다. 국내 수영장은 살균제로서 차아염소산과 오존을 홍용하며, 뉴저지주의 수영장은 차아염소산만으로 살균하므로, 두 지영의 그러한 차이는 100%는 아닐지 라도 최소한 살균 처리 공정의 차이에 기인한 것으로 추정된다. 수영 변수들이 일관성 없이 변하여, 시간이 경과함에 따라 물속의 클롤로포름 농도의 증가 및 감소가 불규칙하게 변했고, 클로로포름 축적도 일정치 않았다는 것이 암시 되었다. 회귀 분석 결과, 시료 채취 시간과 클로로포름 농도 사이에 유의성 없는 것으로 나타났다. 또한 F 시험 결과는 수영장으로 부터 오전과 오후에 채취된물 시료의 클로로포름 놈도는 서로 다르지 않게 나타났다. 국내 수영장 물의 클로로포름 평균 농도를 23.2${\mu}g/l$ 로 간주하여, 한 시간 수영을 할 때 식도를 통해서 체내에 흡수ㅚ는 클롤로포름의 량은 0.58${\mu}g/l$ 으로 추산되었다. 극단적인 상황에서는, 한 시간 수영을 할 경우 식도를 통해서 체내에 흡수되는 크롤로포름의 량이 12${\mu}g/l$ 으로 추산되었다. 수영장 물어서의 클로로포름 함유량을 고려해 볼 때, 오전 또는 오후에 수영을 하든지 간에 식도를 통해서 체내에 흡수되는 클로로포름의 량은 차이가 없는 것으로 간주된다.
