DESCRIPTION:Dr. Jurg Schiffmann\, Fischer Engineering Solutions AG\nBased 
 on the design of an oil-free turbocompressor for driving a domestic heat p
 ump\, an integrated design philosophy is proposed. Compared to fragmented 
 design approaches the integrated optimization allowed an increase of 16 po
 ints on the overall system efficiency. A radial compressor with a tip diam
 eter of 20 mm has been built and tested up to 210 krpm\, reaching pressure
  ratios in excess of 3.2 and isentropic efficiencies above 80% at a power 
 level of 1.7 kW. Experimental data and first principles based models are i
 n excellent agreement. The novel compressor design yields a specific power
  increased by one order of magnitude compared to current systems\, while a
 llowing multi-stage and oil free compression. The technology bears the pot
 ential to increase the performance of residential heat pumps by 15-20%
