Rotary vapour recompression heat pump

This project aimed at developing a new design for heat pumps. The work of the project has led to some useful results, in terms of technical understanding. Moreover, the results have been widely disseminated and some first steps towards commercialisation made.

Typically, air-conditioning machines use vapour compression systems employing chloro-fluoro-hydrocarbons (CFC) refrigerants. This project aimed to develop an efficient heat pump based on a combination of an absorption machine that employs process intensification exploiting radial flow driven by centrifugal force, with a recompression unit. This would result in high heat and mass transfer in the absorption/generation components, thus reducing size. The new system would therefore be compact and of low cost. Its performance would be higher than conventional systems as it would use the combined heat from the recompression unit and the exhaust from the gas engine. Moreover, it would use water as a refrigerant, eliminating the need of CFCs.
