Heating process using a heat pump and a fluid mixture

摘要

Process for producing heat at a temperature level higher than that of an available heat source comprising vaporizing a working fluid of at least two components of different boiling points by heat exchange with said heat source within a first temperature range, compressing at least a portion of the obtained vapor and condensing at least a portion of the compressed vapor in a temperature range whose highest temperature is higher than the highest temperature of said first range while transferring condensation heat to an external medium other than said heat source, expanding the condensed liquid fraction and using it as said working fluid.
