고성능 제습-증발냉각 시스템의 운전모드 제안 및 에너지 절약 가능성 분석

Abstract

To reduce the usage of refrigerants and energy consumption, the desiccant-enhanced evaporative (DEVap) cooling system has been introduced. DEVap cooling system consists of DEVap cooler, regenerator, cooling coil and reheating coil. The purpose of this study is to evaluate energy saving potential of the DEVap cooling system compared with conventional variable air volume (VAV) system. OA intake of this system and operation modes are determined by outdoor air conditions. The simulation is conducted by using TRNSYS 17 program and commercial equation solver (EES) for an arbitrary office single zone in seoul, Korea. The simulation shows the DEVap cooling system can save 4% of primary energy compared to VAV system.
