Process for operating on a working fluid according to a thermodynamic refrigeration cycle

In order to overcome the aforementioned problems, a process and related system was devised to operate on a working fluid producing overheated vapour without the use of additional critical units or intermediate phases to reduce the system footprint and improve 5 process efficiency. Thus, the subject matter of the present invention is a process for operating on a working fluid according to a thermodynamic refrigeration cycle comprising the cyclic steps of: 10 a) evaporating a working fluid in the liquid state in an evaporation unit 10 by generating a vapour stream; the working fluid having initial temperature and pressure conditions; b) compressing at least a portion of the vapour flow from step a) into a compression unit 20 by increasing temperature and pressure of the vapour flow; 15 c) condensing, by giving off heat to an external environment, at least a portion of the compressed vapour fluid from step b) by means of a condensation unit 30 generating a condensate flow; d) laminating at least a portion of the condensate flow from step c) by means of a lamination unit 40 by lowering the temperature and pressure of the condensate flow to 20 obtain the working fluid substantially at the initial temperature and pressure conditions; e) sending the working fluid from step d) to step a); characterized in that step a) involves overheating the vapour flow by at least partial dissolution of at least one non-volatile solute in the working fluid and by heating the resulting solution until the 25 boiling temperature of the solution is reached and consequently producing overheated 4 vapour consisting essentially of the working fluid, said solution having a boiling temperature higher than the boiling temperature of the working fluid. Advantageously, the process and system of the present invention make it possible 5 to improve the efficiency of heat exchange in the cycle and to reduce the total volume of the apparatus for the same power compared to the prior art. Advantageously, the process and system of the present invention allow refrigeration cycle machines and heat pumps to be simplified by removing one or more critical units. Advantageously, the process and system of the present invention for the respective 10 apparatus on which the process is implemented also allow a: • Reduction in investment costs • Reduction in operating costs • Reduction in maintenance costs • Reduction in monitoring and control costs
