Abstract

In this paper, an efficiency grade standard for imaging equipments using electrophotograph printing such as a printer, copier, fax, and MFD (Multi Function Device) is studied. By emphasizing domestic standby power reduction program's problem, and proposing the necessity of efficiency management, the efficiency standard is developed by reliable data registered in domestic standby power reducing program. To find an efficiency indication for grade, correlation analysis is used and as a result, printing speed has the biggest correlation coefficient. By applying the efficiency indication for grade, the proposed certification standard is established in 1st to 5th level products and super-high-efficiency product (energy frontier) which is better than 1st to 5th level products. If these efficiency standards are chosen by government policies, it is expected to save 65 billion won reduction of energy cost per year.

본 논문에서는 전자사진 기술을 이용하는 프린터, 복사기, 팩시밀리, 복합기 등과 같은 이미징 장치의 효율등급기준에 대한 연구를 수행하였다. 대기전력을 관리하고 있는 현 제도의 문제점을 파악하고 효율관리 필요성을 제안하였으며, 이를 위한 효율 기준을 국내 대기전력저감 프로그램에 등록된 실증 데이터를 기반으로 개발하였다. 효율부여지표를 찾기 위해 상관분석(Correlation Analysis)을 실시하였으며, 인쇄 속도가 가장 큰 상관계수(Correlation Coefficient)를 가짐을 확인하였다. 이를 적용한 복합기, 프린터에 대한 1~5 등급의 효율등급 기준과 에너지 프론티어 기준을 도출하였으며, 정책반영 시 연간 약 650 억 원의 에너지 비용을 절감할 것으로 기대한다.
