Control of Compressor and Electronic Expansion Valve for a Tandom-type Air-conditioner

텐덤형 냉방시스템의 압축기와 전자팽창밸브 제어

Capacities of a tandom-type air-conditioner may be modulated by turning on/off multiple compressors and adjusting positions of a electronic expansion valve. In this study. control algorithms for compressors and a electronic expansion valve were developed by using fuzzy’ logics. There algorithms were implemented in a test lab and proved to be effective for the control of indoor air temperature and superheat temperature.
