Device and systems for the revaluation of low-level thermal energy using phenomena of evaporation, and solution of two fluids being in equilibrium of vapour pressure at different temperatures

摘要

The invention relates to a method and to devices for upgrading thermal energy at low level. According to the invention, devices forming evaporator-mixer EM are used, advantageously associated with devices forming evaporator-separator ES to supply heat from a low-level heat source, for example at 25 ° C. at a higher level, for example at 80 ° C., by implementing phenomena of evaporation and mixing of two fluids in vapor pressure equilibrium under different temperatures. The invention also allows and is particularly applicable to the recovery of the noble thermal energy consumed in a high temperature CH boiler. For this purpose, the heat released in the boiler is used firstly to ensure in ES evaporator-separators the formation or reconstitution of concentrated solutions c from dilute solutions d, and these are used according to the needs of the request. concentrated solutions for extracting heat from a low-level source using EM evaporator-mixers. The invention applies in particular to residential or industrial heating installations.
