초록

본 연구에서는 폐열회수형 환기장치 전열교환기 로부터의 휘발성 유기화합물이 측정되었다. KS 냉방 및 난방 표준조건하에서 휘발성유기화합물의 초기 배출특성을 연구하기 위하여 폐열회수 환기장치로부터 종류의 열교 환소자(L형과 M형)가 평가되었다. 휘발성 유기화합물은 다양한 풍량 변화와 운전시간 변화에 대하여 측정되었다. 본 연구의 분석방법 및 기기상의 한계로 인하여 농도가 비교적 큰 물질만을 살펴보니 폐열회수 환기장치에서는 acetic acid, 2-butanone (MEK), 2-(methylthio)ethylamine, toluene, styrene 및 x-acids (Ion 57) 등 의 6종의 휘발성 유기화합물이 배출됨을 확인하였다. 배출된 휘발성 유기화합물의 농도는 운전조건에 대해서는 크게 영향을 받지 않았다. 높은 작동온도 때문에 휘발성 유기화합물의 농도는 난방조건보다는 냉방조건에서 더 크게 나타났다.

VOCs from the heat recovery ventilation system (total heat exchanger) are measured in this study. Two different types of element (L and M type) from heat recovery ventilating system are tested to study the intial release characteristics of VOCs under KS cooling and heating standard conditions. VOCs are measured for the various flow rates and different operating times. Considering errors in the test method and the measuring instrument, the tested heat recovery ventilating systems was found to release 6 major VOCs, such as acetic acid, 2-butanone (MEK), 2-(methylthio)ethylamine, toluene, styrene, and x-acids (Ion 57). The concentrations of released VOCs are not quite much affected by operating conditions. The results show much larger VOCs concentrations in the cooling mode than in the heating mode, due to the high operating temperatures..
