          이중외피와 할로우 코어를 적용한 초고층 주거건물의 에너지 절감 방안에 관한 연구

          이승복,원종서 대한건축학회 2005 대한건축학회논문집 Vol.21 No.3

          The environment pollution is very important problem. Even at the field of architecture, a study about method of energy saving and constructing environment friendly building will have performed with activity. But trends of Korea housing market are changed that the height of building become more higher and the level of comfort going up. Therefore, these requirements force to increase the energy usage for indoor environmental controls. Thus, this study aims at reducing the heating and cooling energy requirements of high-rise residential complex using twin skin facade and hollow core. Based on ESP-r simulation, the alternatives of facade design compare to the conventional facade design. The alternatives is as following. 1) Basecase(expanded balcony), 2) Expanded balcony + Hollow Core, 3) Twin Skin facade, 4) Twin Skin facade + Hollow Core. If outdoor temperature higher than 26℃, the air temperature of passing hollow core low maximum 7℃. In winter, the air temperature of passing hollow core higher outdoor temperature. Thus using hollow core could reduce heating and cooling energy. It was confirmed that the possibility of natural ventilation strategies through twin skin facade during mid-term(15℃~26℃). The flow rate assumed from 0.74 ACH to 23.80 ACH(average flow rate 7.56 ACH). Therefore, If utilize twin skin facade at the high-rise building, natural ventilation could possible and cooling energy could reduce. The results of the simulation show that the facade using hollow core could reduce 16% of heating and cooling energy, the twin skin facade could reduce 85% of heating and cooling energy, the facade using hollow core and twin skin could reduce 88% of heating and cooling energy compared to conventional facade design.

          이승복,원종서 대한건축학회 2005 대한건축학회논문집 Vol.21 No.3

          The purpose of this study was to evaluate the indoor environmental conditions for comfort and energy performance of radiant floor cooling·heating system integrated with controlled ventilation compared to a conventional solution with packaged air-conditioning·boiler. The alternatives of 5 system types were investigated through TRNSYS simulation for 2 heating alternatives: 1) ALT-1(radiant heating with boiler) and 2) ALT-2(radiant heating with solar collector), and 3 cooling alternatives: 3) ALT-3(packaged air-conditioning), 4) ALT-4(radiant cooling with chiller), 5) ALT-5(radiant cooling with geothermal energy). Based on simulation results, it was confirmed that all alternative systems could provide heating and cooling for occupants comfort. In terms of energy performance, ALT-2 was superior than ALT-1, and ALT-4, ALT-5 demonstrated better performance than ALT-3. From the combined heating and cooling cost point of view, the radiant floor cooling and heating system(boiler+chiller) could reduce the energy cost by 58.8% of the cost by boiler and PAC and it could further reduce by 86.8% when the solar and geothermal energy was used as heat sources.

          미래 사회를 대비하기 위한 개인의 개성을 존중과 창의적인 능력을 지닌 인간을 양성을 목적으로 충청남도 지역의 초 ㆍ 중고등학생들을 대상으로 한 창의력 경연대회가 공주대학교 과학교육연구소에서 개최되었다. 충청남도 초 ㆍ중 ㆍ 고등학생들을 대상으로 실시한 창의력 경연대회는 창조적 아이디어를 내어 스스로 문제를 해결해 나갈 수 있는 교육 프로그램을 제공하는 좋은 기회였음이 확인되었으나, 일부의 팀에서만 참신하고 재미있는 아이디어들이 제안되었다. 여학생의 참가자 수가 상당히 증가하였으며, 대체적으로 입상권의 학생들의 상당 부분이 여학생이라는 것이 특이할만하다. 학년이 올라감에 따라서 창의적인 아이디어를 내는 양이나 질에 있어서 뒤떨어지는 것으로 분석되었으며, 토론 학습의 적응력이 미흡하고 발표력 및 청취력에 있어서도 떨어지는 것으로 나타났다. 따라서 중 ㆍ고등학교의 학교교육에서도 학생들에게 프로젝트형 탐구학습 프로그램의 적용은 물론 토론식 수습을 통한 학생들의 사고의 전환의 기회를 제공해야 할 것으로 사료된다. The creativity competition was held to foster the creativity of elementary and secondary school students in the Institute of Science Education, Kongju national University. It was found that the creativity competition effected on the improvement of inventing creative ideas and problem solving activities. But, only some competitors participated in semifinal and final contests, presented original and interesting ideas. More female students participated in competition than last year. More female participants were awarded a prize than males. Totally, participants were defective in discussion and communication, and presentation and listening ideas. Increasing grades correlated inversely with creativity and originality. There is need of inquiry project teaming programs and presenting opportunities of conversion of thinking by discussing instructions in school

          Rheological parameters of PAN(polyasrylonitrile)-slurry such as shear modulus, relaxation time, structural factor, etc. have been determined. Axial concentration distribution and axial dispersion coefficient of slurry particles have been investigated in a PAN-slurry bubble column(0.10 m-ID x 1.53 m-height). Effects of gas velocity(0.03-0.11 m/s), apparent slurry viscosity ?? and concentration of slurry particles ?? on the axial concentration distribution and dispersion coefficient of slurry particles have been determined. Sedimentation-dispersion model has been employed to analyze the axial concentration distribution of slurry particles. The axial distribution of slurry particles became uniform with increases in gas velocity, apparent slurry viscosity and slurry particle concentration. The axial dispersion coefficient of slurry particles increased with increasing gas velocity, but it decreased with an increase in apparnet viscosity of slurry. By considering the relation between rheological properties and axial dispersion of slurry particles, we found the following correlation equation; ? ?

        • 석탄 슬러리 기포탑에서 초음파에 의한 슬러리 입자의 축방향 분산 촉진

          최상원,나종복,서호준 麗水水産大學産業技術硏究所 1992 産業基術硏究所 論文集 Vol.1 No.-

          In a semi-batch coal slurry bubble column(0.10m-IDx1.53 m-height),the effects of gas velocity(0.02-0.10 m/s),apparent slurry viscosity(1.2x10?-3.82x10?Pa·s),concentration of slurry particles(10.04-51.25kg-solid/m³-slurry)and ultrasound on the axial concentration distribution of slurry particles have been determined. Sedimentation-dispersion model and modified sedimentation-dispersion model have been applied to analyze axal concentration distribution of slurry particles. The axial distribution of slurry particles became uniform with increases in gas velocity, apparent slurry viscosity and slurry concentration,and by introduction of ultrasound. The axial dispersion coefficient of slurry particles increased with increasing gas velocity,but it decresed with increasing apparent viscosity of slurry. The magnitude of the axial dispersion coefficient increased to about 2-5 times by using ultrasound in comparison with that without ultrasound. The axial distriution of slurry particles from the experiments agreed well with that obtained from the modified sedimentation-dispersion model, in which the particle size distribution of slurry particles was considerd.
