Abstract

Recently, the distributed power generation market using natural gas is expected to expand gradually according to the government's future energy conversion policy. Distributed power generation means small power generation source near the power demand site, which has the advantage of reducing the construction costs of the transmission and distribution infrastructure, operating cost and power loss. A typical example of distributed generation using natural gas is the trigeneration system. In this study, we conducted a basic study on the performance analysis of trigeneration desiccant system for dehumidifying / cooling / heating in the air conditioner room by using the cold and engine waste heat energy generated in the trigeneration system. It shows that the system efficiency increases and the energy consumption decreases as the temperature difference between the inlet and outlet of the trigeneration system increases compared with the general air conditioning system.

최근 정부의 미래에너지변환 정책에 따라 천연가스를 활용한 분산발전 시장은 점차 확대될 것으로 예상된다. 분산발전은 전력 수요지 주위의 소규모 발전원을 활용하는 발전방식으로 송배전 인프라 구축 비용과 운용비용, 전력손실을 줄일수 있는 장점이 있다. 천연가스를 이용한 분산발전의 대표적인 예로 Trigeneration System이 있다. 본 연구에서는 Trigeneration System에서 발생되는 냉열 및 엔진 배열을 이용하여 공조대상 실내의 습공기를 제습/냉방/난방 하는 제습공조시스템의 성능 분석에 대한 기초 연구를 수행하였다. 연구결과 제습공조시스템 입출구 온도차가 커질수록 시스템 효율은 높아지고 일반공조시스템 대비 에너지 소비량이 감소하는 것을 알 수 있었다.
