An energy conversion system including a high efficiency absorption heat pump cycle is disclosed using a high pressure stage, a supercritical cooling stage, and a mechanical energy extraction stage to provide a non-toxic combined heat, cooling, and energy system. Using the preferred carbon dioxide gas with partially miscible absorber fluids, including the preferred ionic liquids as the working fluid in the system, the present invention desorbs the CO 2 from an absorbent and cools the gas in the supercritical state to deliver heat. The cooled CO 2 gas is then expanded, preferably through an expansion device transforming the expansion energy into mechanical energy thereby providing cooling, heating temperature lift and electrical energy, and is returned to an absorber for further cycling. Strategic use of heat exchangers, preferably microchannel heat exchangers comprised of nanoscale powders and thermal-hydraulic compressor / pump can further increase the efficiency and performance of the system.

L'invention porte sur un système de conversion d~énergie comportant un cycle à haut rendement de pompe à chaleur à absorption utilisant: un étage haute pression; un étage de refroidissement super critique; et un étage d~extraction d~énergie mécanique, de manière à former un système combiné non toxique de chaleur, froid et énergie.En utilisant le CO2 préféré avec des fluides absorbants partiellement miscibles dont des liquides ioniques préférés comme fluide de travail du système, l'invention désorbe le CO2 de l~absorbant et refroidit le gaz à l~état super critique pour fournir de la chaleur. Le CO2 est alors dilaté, de préférence par un dispositif de dilatation qui transforme l~énergie de dilatation en énergie mécanique, assurant ainsi le refroidissement, et une élévation de la température de chauffage, et fournissant de l~énergie électrique, puis le CO2 retourne dans l~absorbeur pour un nouveau cycle. L~utilisation stratégique des échangeurs de chaleur de préférence à micro canaux utilisant des poudres à l'échelle nano et des pompes/compresseurs thermohydrauliques peut ainsi encore renforcer les rendemants et les performances du système.
