스크롤 압축기 사체적 축소를 통한 체적 효율 개선에 관한 연구 = Research on volumetric efficiency improvement through physical reduction of scroll compressor

국문 초록 (Abstract)

공조산업 전반에 걸쳐 환경규제 및 에너지 절감 정책이 강화되면서 에너지 효율 규제가
지속적으로 강화되고 있고, 이러한 규제 강화로 인한 고효율 압축기의 기술 개발이 진행되
고 있다. 북미 Unitary 시장에서는 정속형 스크롤 압축기의 고효율화 개발이 활발히 이루
어지고 있고, 이에 압축기 개발 업체는 지속적인 고효율 압축기 개발을 위한 기술 개발에
집중하고 있다. 스크롤 압축기의 효율은 지시, 체적, 기계, 모터효율로 나눌 수 있는데, 기
계 효율은 마찰되는 마찰 손실을 최소화해야 하지만, 압축기의 부하 지지능력과 상충되어
한계가 있기 때문에 지시, 체적 효율을 개선해야 한다. 본 연구에서는 스크롤 압축기의 체
적효율을 개선하기 위한 인자를 해석을 통하여 도출하였고, 그 인자들에 대해서 검토 결과
압축부의 사체적을 최소화 하는 설계가 체적효율에 큰 영향을 줄 수 있는 인자라고 결론을
내렸다.

Energy efficiency regulations are continuously strengthened throughout the air
conditioning industry, and technology development of high efficiency compressors is
underway due to these regulations being strengthened. In the North American Unitary
market, high efficiency development of constant speed scroll compressors is actively taking
place. The efficiency of a scroll compressor can be divided into instruction, volume,
mechanical, and motor efficiency. The mechanical efficiency should minimize the friction
loss, but since there is a limit due to the conflict with the load support capacity of the
compressor, the instruction and volume efficiency should be improved. In this study, the
factors for improving the volume efficiency of the scroll compressor were derived through
analysis, and as a result of reviewing the factors, it was concluded that the design that
minimizes the carcass volume of the compression part was a factor that could have a great
influence on the volume efficiency
