Pod\u00edvejme se na to, jak tahle praktick\u00e1 pom\u016fcka do dom\u00e1cnost\u00ed funguje.

Ten m\u00e1 schopnost dlouhou dobu udr\u017eet n\u00edzkou teplotu. Na rozd\u00edl od oby\u010dejn\u00e9ho ledu m\u00e1 v\u00fdhodu, \u017ee se nerozt\u00e9k\u00e1 do vody. Vydr\u017e\u00ed tak\u00e9 d\u00e9le chladn\u00fd a je opakovateln\u011b pou\u017eiteln\u00fd.Jak funguje princip chlazen\u00ed?Z\u00e1kladen je princip p\u0159enosu tepla. Kdy\u017e chlad\u00edc\u00ed vlo\u017eku nech\u00e1te zmrazit t\u0159eba v mraz\u00e1ku, gel \u010di tekutina v n\u00ed se ochlad\u00ed na velmi n\u00edzkou teplotu, Pot\u00e9, co ji vlo\u017e\u00edte do ta\u0161ky, za\u010dne gel absorbovat teplo z okol\u00ed, t\u0159eba z j\u00eddla nebo ze vzduchu. T\u00edm se postupn\u011b zah\u0159\u00edv\u00e1, zat\u00edmco okol\u00ed se ochlazuje. Jin\u00fdmi slovy, vlo\u017eky vytahuj\u00ed teplo z v\u011bc\u00ed kolem sebe.Jak funguj\u00ed v praxi?Aby mohli chlad\u00edc\u00ed vlo\u017eky fungovat co nejl\u00e9pe, je d\u016fle\u017eit\u00e9 je spr\u00e1vn\u011b pou\u017e\u00edvat. Dejte vlo\u017eky do mraz\u00e1ku, alespo\u0148 na 6-12 hodin. Potom je um\u00edst\u011bte na dno termo ta\u0161ky nebo termo boxu. Kombinujte v\u00edce vlo\u017eek, aby to m\u011blo lep\u0161\u00ed efekt. A minimalizujte otev\u00edr\u00e1n\u00ed ta\u0161ky, aby chlad neut\u00edkal. Nejlep\u0161\u00ed efekt toti\u017e vlo\u017eky maj\u00ed v uzav\u0159en\u00e9m prostoru.Jak dlouho vydr\u017e\u00ed vlo\u017eky chladit?Doba, jak dlouho vydr\u017e\u00ed chlad\u00edc\u00ed vlo\u017eky chladit obsah termo ta\u0161ek, z\u00e1le\u017e\u00ed na n\u011bkolika faktorech. Je to t\u0159eba velikost a kvalita vlo\u017eek. Tak\u00e9 okoln\u00ed teplota je d\u016fle\u017eit\u00fdm faktorem. Pokud je venku chladn\u00e9 po\u010das\u00ed, vlo\u017eky vydr\u017e\u00ed chladit d\u00e9le, ne\u017e kdy\u017e je velk\u00e9 horko. Z\u00e1le\u017e\u00ed tak\u00e9 na typu ta\u0161ky. V oby\u010dejn\u00fdch ta\u0161k\u00e1ch nebudou vlo\u017eky chladit tak dob\u0159e, jako t\u0159eba v termo ta\u0161k\u00e1ch. A taky z\u00e1le\u017e\u00ed na mno\u017estv\u00ed ulo\u017een\u00fdch potravin. Obvykle ale doba chlazen\u00ed je 4 a\u017e 12 hodin. Je to ale individu\u00e1ln\u00ed. Hlavn\u00ed je, abyste vybrali kvalitn\u00ed chlad\u00edc\u00ed vlo\u017eky.
