Latest Patents
Eva holds a patent for a "Method for operating an absorption refrigeration unit." This method involves a refrigerating unit that includes an expeller, condenser, evaporator, and absorber, utilizing a solvent circulation, working substance circulation, and by-gas circulation. The working substance, ammonia, is expelled from a rich ammonia solution with a continuous supply of thermal energy. It is subsequently liquefied by heat absorption, evaporated with heat absorption from a cooling chamber, and absorbed from a weak ammonia solution. The regulation of the thermal energy required for expulsion is managed based on temperature changes in relation to a specified temperature of the cooling chamber, using an electronic module that employs fuzzy logic rules. This innovative approach enhances the efficiency and effectiveness of refrigeration systems.
