  • The purpose of this study is to analyse the effects of air conditioned room controlled by PMV(Predicted Mean Vote)for energy consumption and human comfort in office building. The 'EnergyPlus' was used for the evaluation of indoor thermal environment and energy consumption by the controls of room temperature and PMV. The result indicates that the PMV control could prove more profitable method for improvement of indoor thermal environment and energy conservation. Consequently, PMV control has a distinct advantage over most other control methods. An additional study is required to establish the various thermal comfort control for rooms on the basis of this work.

  • To those who spend most time within a room, comfortable indoor environment is a very critical element to job performance and health. The comfort technology, which is for enhancing comfort in human living, relates with various factors to ensure human activities efficient, comfortable, safe and satisfactory. Experiments were performed in environmental chamber. Experimental conditions were combinations from three temperatures of 18, 22 and 26C, and two relative humidity levels of 45 and 60%. Air-flow was controlled to 0.1m/s through the experiment. Four male and four female university students participated in the experiments. They had normal blood pressure and their body temperature was under $37^{\circ}C$. From the experiments for evaluating thermal sensation to the air-heating conditions, relationships among TSV, CSV, $SET^*$, PMV were analyzed. Results can be summarized as followings; Thermal neutrality $SET^*$ of man and female was $24.8^{\circ}C$. In air-heating condition, $SET^*$ values for thermal comfort zone were $23.0{\sim}26.5^{\circ}C$. These values were higher than the values from ASHRAE.

  • 환경부는 2006년 12월에 대중교통수단 실내공기질 관리 가이드라인을 마련하였다. 관리항목으로 이산화탄소($CO_2$)와 미세먼지(PM10)에 대해 가이드라인을 제시하였다. 이에 따라 객차내 온열환경에 대한 관심이 높아지고 있으며, 승객이 실내에서 느끼는 온열환경 범위는 어느 정도인지 연구의 필요성이 대두되고 있다. 본 연구는 KTX, 무궁화호, 새마을호 객차 실내를 대상으로 2007년 9월과 10월에 측정을 하였다. 그리고 ASHRAE Handbook에 제시하고 있는 온열환경 범위가 어느 정도인지 분석하였다. 그 결과 평균 PMV 값은 KTX가 0.1과 0.22, 무궁화호가 0, 새마을호가 0.1로, 이는 ASHRAE Handbook의 -0.5 < PMV < +0.5범위에 만족한 수준으로 나타났다.
