Based on the design of an oil-free turbocompressor for driving a domestic heat pump, an integrated design philosophy is proposed. Compared to fragmented design approaches the integrated optimization allowed an increase of 16 points on the overall system efficiency. A radial compressor with a tip diameter 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 in excellent agreement. The novel compressor design yields a specific power increased by one order of magnitude compared to current systems, while allowing multi-stage and oil free compression. The technology bears the potential to increase the performance of residential heat pumps by 15-20%
