고성능 제습-증발냉각 공조시스템의 에너지 절감효과 및 고분자 전해질 연료전지 적용성 분석

Abstract

This study was conducted to evaluate primary energy savings for a desiccant-enhanced evaporative (DEVap) air-conditioning system with proton exchange membrane fuel cell (PEMFC) and applicability of PEMFC supplying power and heat to meet air-conditioning system demands compared with conventional variable air volume (VAV) air-conditioning system. DEVap is newly introduced system independently operating liquid desiccant and regenerative indirect evaporative cooler depending on sensible and laten loads. Heat energy is need to regenerate diluted liquid desiccant. In this study, PEMFC generates power and heat simultaneously, and thus fuel cell is applied to both systems requiring power and heat. As a result, DEVap with PEMFC showed about 30.5% annual primary energy savings and high applicability.
