Twenty years of compressor innovation at NTU, Singapore.

Number: pap. 1669

Author(s) : OOI K. T.

Summary

In this paper, innovations in refrigeration compressors and their mechanisms which were conceptualized (and some of these were commercialized) at Nanyang Technological University in Singapore over the past twenty years are discussed and presented. These innovations include piezo compressor [1-4], rotaprocating compressor [5-6], sliding cam compressor [7], revolving vane compressor and its variants [8-28], twin-plate rotary compressor [29], revolving vane expander [30-40] and cross-vane mechanism for expander-compressor unit [41-43]. The revolving vane compressor had won the World Best Technology Showcase, in Arlington, Texas, USA in 2009 and it has licensed to a Japanese compressor manufacturer for air-conditioning applications in automobile and private boats sectors, while the invention of the piezo compressor was sold to another Japanese compressor manufacturer. In this paper the working principles of each of these innovations, their uniqueness, advantages and challenges in applications will be shown and discussed.
