전열교환 환기유니트용 엘리먼트 코어의 스페이서 재질 및 가공방법에 따른 성능평가

Abstract

Recently, efficiency of ventilation for improvement IAQ(Indoor Air Quality) has been obvious, simultaneously, as the importance about saving energy is getting higher, the studies about heat recovery ventilation are being progressed actively in domestic. The existing studies occupy the comparison and valuation by the shape change of element core and the material of liner and feature on the purpose to increase efficiency of heat recovery ventilation's element core for the most part, also performance valuation by spacer which is one of the important factor hasn't been performed systematically.The purpose of this study in another point of view with existing study is to establish the optimum design strategy of element core for heat recovery ventilation through the efficiency experiment about difference in efficiency which is followed by material of spacer and processing method ventilation by comparing and evaluating. This experiment was performed as object of element core which has the same shape(pitch and hight).The results of this study are as follows. The efficiency of element core which was manufactured by chemicals for hygroscopic property to spacer or liner presented superiorly and among others, the thing which calcium chloride was contained in spacer as well is better than the thing which was treated with lithium chloride at only liner for improvement of efficiency, and the design which extend a contacting area by putting pleat at spacer doesn't show the large efficiency rather than the thing which raise the water vapor transmission of liner itself but it makes efficiency increase.
