Abstract

The invention relates to a cooling accumulator containing a liquid coolant filled into a cell which, compared to its dimensions of length and width, is relatively thin, is expediently hermetically sealed and has a high thermal transmittance. The essence of the invention is that the liquid coolant contains at least 80% of distilled water, furthermore a component of the admixed group formed from methylcellulose and oxyethylmethylcellulose, furthermore NH4Cl compound and benzoic acid. <IMAGE>

Description

HU 203 261 AHU 203 261 A

A találmány hűtőfolyadékra vonatkozik hűtőakkumulátorok töltésére. Az ilyen akkumulátorok biztonságosan alkalmazhatók mélyhűtő- és fagyasztókészülékek biztonságos üzemeltetéséhez, valamint egyéb élelmiszerhűtési célokra.The present invention relates to a coolant for charging cooling batteries. Such batteries can be safely used for safe operation of freezers and freezers as well as for other food refrigeration purposes.

Ismeretes, hogy nagyobb mennyiségű fagyasztott élelmiszert tároló eszközöknél a mélyhűtve tárolt élelmiszerek felmelegedése jelentős károk előidézője lehet.It is known that, in the case of larger quantities of frozen food storage devices, the warming of deep-frozen foods can cause significant damage.

Az élelmiszerek veszélyes felmelegedéséhez szükséges idő jelentős mértékben növelhető úgynevezett hideg-akkumulátorok segítségével. Ezek különleges, zárt lapos műanyag dobozok, amelyekben az előzetesen megfagyasztott eutektikus oldat a felmelegedés során a vízjéghez hasonlóan hosszú ideig állandó hőmérsékleten marad (olvadási hőmérséklet), miközben a környezetétől jelentős mennyiségű hőt von el, azaz hűti azt.The time needed for dangerous food to warm up can be significantly increased by using so-called cold batteries. These are special, sealed flat plastic cans in which the pre-frozen eutectic solution remains at a constant temperature (melting temperature) for a long period of time similar to water ice, while removing a significant amount of heat from its surroundings, ie cooling it.

Ezeknél a hidegakkumulátoroknál általában gondot kell fordítani a hűtőakkumulátorok lezárására, mert azok rendszerint olyan folyadékot tartalmaznak, amely gondatlan lezárás esetén az élelmiszer környezetébe és ezáltal az emberi szervezetbe jut, ott nemkívánatos elváltozást eredményezhet.These cold accumulators generally require care to close the refrigeration accumulators because they usually contain a liquid that, if carelessly sealed, enters the food environment and thereby the human body, and may result in unwanted damage.

Találmányunk elé azt a célt tűztük ki, hogy olyan hűtőfolyadékot hozzunk létre, amely elsősorban mélyhűtő- és fagyasztókészülékeknél alkalmazható és széles körben történő alkalmazhatóságát nagymértékben elősegíti az a tény, hogy a hűtőfolyadék mérgező anyagot nem tartalmaz és igen magas hőkapacitással rendelkezik.It is an object of the present invention to provide a coolant which is particularly applicable to deep-freezing and freezing apparatuses and its wide applicability is greatly enhanced by the fact that the coolant does not contain a toxic substance and has a very high heat capacity.

A kitűzött célnak a találmány értelmében olyan hűtőfolyadékkal teszünk eleget, amely legalább 80 tömegé desztillált vizet, továbbá ahhoz kevert 2-10 tömegei metilceUulózt vagy oxyetilmetilcellulózt, valamint 2-11 tömeg% NH4C1 vegyületet és 0,1-1 tömegé; benzoesavat tartalmaz.The object of the present invention is achieved by a coolant comprising at least 80% by weight of distilled water and 2-10% by weight of methylcellulose or oxyethylmethylcellulose and 2-11% by weight of NH 4 Cl and 0.1-1% by weight; Contains benzoic acid.

Úgy találtuk, hogy a hűtőakkumulátor határoló falait képező dobozba speciális sóoldatot kell tölteni amely egészségügyi szempontból közömbös -, az oldat, töménységétől (koncentrációjától) függően, az adott hűtési feladat által igényelt -18 °C, -12 °C vagy -6 °C olvadásponttal rendelkezhet.It has now been found that a container containing the boundary walls of the refrigerator battery needs to be filled with a special saline solution which is health inert - depending on the concentration (concentration) of the solution, with the melting point of -18 ° C, -12 ° C or -6 ° C You may have.

A kevésbé alacsony fagyáspontú oldattal töltött hideg-akkumulátorok az előbb említett cél mellett alkalmasak hűtőtáskák (kemping-táskák) hűtésére, ugyanakkor éttermekben, cukrászdákban, bárokban vagy akár a háztartásokban is tálcaként használhatók italok, fagylaltok, krémek, hidegkonyhai készítmények hűtött felszolgálására is.Cold accumulators filled with a solution with a lower freezing point are suitable for the cooling of refrigeration bags (camping bags), while beverages, ice cream, creams, cold kitchen preparations can also be used as trays in restaurants, confectioneries, bars or even in households.

A hűtőakkumulátor töltete, az ún. eutektikus hűtő5 folyadék összetétele a különböző fagyáspontoktól függően az alábbi példák szerint hozható létre.The charge of the refrigerator battery, the so-called.
