연료전지 적용을 통한 제습 증발냉각 기반 전외기 공조 시스템의 1차 에너지 절감효과 분석

Abstract

The purpose of this study is to evaluate primary energy saving compared with the existing system when applied to fuel cellsystems in the LD-IDECOAS (Liquid Desiccant Indirect and Direct Evaporative Cooling Assisted 100% Outdoor Air System). A fuel cell is a system that is producing electricity and heat by chemical reactions occurring Hydrogen and oxygen combine. In previous studies, we used purchased electricity and the LPG gas boiler which is required electricity and heat by LD-IDECOAS. In this study, however, the heating load excluding the heat generated in the fuel cell, is responsible boiler and the electrical load uses electricity to produce the fuel cell.
