연료전지 적용을 통한 제습 증발냉각 기반 전 외기 공조 시스템의 1차 에너지 절감 효과 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). Afuel cell is a system that is producing electricity and heat by chemical reactions occurring Hydrogen and oxygen combine. Inprevious studies, we used purchased electricity and the LPG gas boiler which is required electricity and heat by LD-IDECOAS. Inthis study, however, the heating load excluding the heat generated in the fuel cell, is responsible boiler and the electrical load useselectricity to produce the fuel cell.
