The goal of this project is to demonstrate the feasibility of winding/weaving light-weight, high-strength composite turbo-impellers with integrated motor and bearings on a commercially available winding machine. This will provide a very much needed scalable and economical compressor which uses water (R718) as the refrigerant. Being one of the most natural refrigerants, water vapor, combined with wound composite turbo-impellers, will facilitate the implementation of the most novel, environmentally friendly, highly efficient chiller concept that can be highly successful in the US HVAC&R market and beyond.
