Tipin\u0117s \u0161aldymo sistemos veikia garavimo\u2013kondensacijos ciklu: \u012frenginyje esantis skystis i\u0161 aplinkos sugeria \u0161ilum\u0105, i\u0161garuoja, v\u0117liau kondensuojasi ir pavirsta dujomis, kurios per u\u017edar\u0105 vamzd\u012f transportuojamos ir v\u0117l kondensuojamos \u012f skyst\u012f.

Jonokalorinis v\u0117sinimas si\u016blo kitok\u012f princip\u0105: jis i\u0161naudoja poky\u010dius, kurie vyksta, kai med\u017eiaga kei\u010dia faz\u0119.

Vietoje to, kad keltume erdv\u0117s temperat\u016br\u0105, kad ledas tiprt\u0173, mes pasitelkiame jonokalorinius ciklus, kurie kei\u010dia lydymosi temperat\u016br\u0105 jon\u0173 jud\u0117jimu \u2014 elektros srov\u0117 stumia \u012fkrautas daleles ir taip ver\u010dia med\u017eiag\u0105 keisti savo faz\u0119.<\/p>\n

Lawrence Berkeley nacionalin\u0117s laboratorijos ir Kalifornijos universiteto Berklio mokslinink\u0173 2023 m. pristatytas modelis ir pirmieji eksperimentai parod\u0117, kad \u0161is metodas gali b\u016bti itin efektyvus. Tyr\u0117jai atliko bandymus su jodu ir natrio druska etilenkarbonato tirpiklyje \u2014 med\u017eiagoje, kuri pla\u010diai naudojama li\u010dio jon\u0173 baterijose. Eksperimente, taikant ma\u017eesne nei 1 volto \u012ftamp\u0105, u\u017efiksuotas temperat\u016bros kritimas net 25 laipsniais. Mokslinink\u0173 teigimu \u0161is rezultatas gerokai lenkia ankstesnes technologijas.<\/p>\n

Komandos nariai pabr\u0117\u017eia tris pagrindinius \u0161ios technologijos tikslus: ma\u017eas \u0161aldymo med\u017eiagos pasaulinio at\u0161ilimo potencialas, energijos efektyvumas ir \u012frangos savikaina. \u201eNuo pat pirm\u0173j\u0173 bandym\u0173 duomenys atrodo labai perspektyv\u016bs visais trim aspektais\u201c, \u2014 sak\u0117 mechanikos in\u017einierius Ravi Prasher i\u0161 Lawrence Berkeley laboratorijos.<\/p>\n

Vis d\u0117lto mokslininkai \u012fsp\u0117ja, kad iki komercini\u0173 sprendim\u0173 dar toli: reikia perkelti technologij\u0105 i\u0161 laboratorini\u0173 prototip\u0173 \u012f didesnio masto sistemas, i\u0161spr\u0119sti in\u017einerinius i\u0161\u0161\u016bkius ir optimizuoti med\u017eiag\u0173 derinius. Vyksta eksperimentai su \u012fvairiomis druskomis \u2014 naujausi tarptautin\u0117s komandos 2025 m. rezultatai rodo, kad nitrat\u0173 pagrindu pagamintos druskos, apdorotos elektros laukais ir membranomis, suteikia ypa\u010d ger\u0173 rezultat\u0173.<\/p>\n
