Graphene based crycooler compressor

Research Project, 2015 – 2016

APR Technologies develops a miniaturized compressor with no moving parts, powered by thermal energy. Graphene-based film (GBF) is seen as a suitable material for the critical component that will ensure the compressor needs of internally extremely high thermal conductivity. It is really the combination of very high thermal conductivity and the possibility of an adapted permeability to gases that make graphene based films to a unique candidate materials. In the project, we take a great technological leap forward and verifies operation of all included component parts.

In the project graphene based films with properties that are better than the commercially available alternatives have been developed. These films have been integrated with other constituent materials and for the first time demonstrated gas compression in an integrated and connected in series, cascade of Knudsenkompressors. The compressor has been iterated and optimized by computer simulation. During the integration work, new methods for processing GBF as well as aerogel composites are developed.
