응축수를 이용한 냉각기의 냄새원인물질 평가방법 검토

Abstract

Uncomfortable odor emitted from air conditioning system is the main cause of indoor air qualitydeterioration. To solve evaporator odor problems, odor active compounds, have to be identified then the qualityof the product can be improved its quality. Because evaporator odor in exhaust gas has low odor intensityand discontinuity, it is very difficult to collect and analyze sample. In this study through the identification ofodor compounds in condensed water, the evaluation of the eraporator was tested. Odor compounds were extractedfrom water by headspace-solid-phase microextraction (HS-SPME) method. The single odor was separated byGC/FID/Olfactometry (GC/FID/O) and odor active compounds were identified by GC/AED. and GC/MS.Compared to air sample, result of sensory.evaluation and the single odor compound appeared similarly. It wasidentified that odor active compounds have functional group containing oxygen such as alcohols and acids.Evaluation method of odor active compounds using condensed water in evaporator appeared effective on theside of simplicity of collection, low expanse and rapid analysis.
