Izboljšan hladilni sistem hladilnega aparataImproved refrigeration system cooling system
Predlagani izum se nanaša na izboljšani hladilni sistem hladilnega aparata, prednostno gospodinjskega hladilnega aparata, ki obsega vsaj eno celico, v kateri se nahaja vsaj en predelek za shranjevanje živil pod ali nad temperaturo ledišča, pri čemer je omenjeni predelek hlajen s pomočjo vsaj enega cevno lamelnega uparjalnika, razporejenega ob vsaj eni steni omenjene celice.The present invention relates to an improved refrigeration system of a refrigeration apparatus, preferably a domestic refrigeration apparatus, comprising at least one cell in which at least one food storage compartment is located below or above freezing temperature, said compartment being cooled by at least one tubular lamellar an evaporator arranged along at least one wall of said cell.
Hladilni sistem hladilnega aparata uvodoma navedene vrste je znan. Tako obstajajo rešitve v hladilnih aparatih z eno celico, v kateri se eden ali več predelkov hladi s cevno lamelnim uparjalnikom, nameščenim ob zadnji steni ali pod zgornjo steno in pri tem omogoča shranjevanje živil pod in/ali nad temperaturo ledišča. Prav tako so znane izvedbe hladilnih aparatov z dvema ali več celicami, pri katerih je v eni od teh celic, ob zadnji steni ali pod zgornjo steno, nameščen cevno lamelni uparjalnik, ki hladi eno ali več celic.The refrigeration system of the refrigeration apparatus of the type mentioned above is known. Thus, there are solutions in one-cell refrigerators in which one or more compartments are cooled by a tubular lamellar evaporator mounted near the rear wall or below the upper wall, allowing food to be stored below and / or above freezing temperature. Embodiments of refrigerating appliances with two or more cells are also known, wherein a tubular vaporizer is provided in one of these cells, adjacent to the rear wall or below the upper wall, to cool one or more cells.
Pogoste so izvedbe hladilnih aparatov s cevno lamelnimi uparjalniki v tako imenovani No Frost izvedbi, kar pomeni, da s pomočjo električnega grelnika, nameščenega na ali v bližini cevno lamelnega uparjalnika, aparati samodejno odtaljujejo na uparjalniku nastali srež ali led, ki se ga zatem na znan način odvede izven celice, tako da uporabnikom tovrstnih hladilnih aparatov ni potrebno skrbeti za odtaljevanje in odstranjevanje sreza ali leda iz celic.There are frequent versions of refrigerating appliances with tubular lamellar evaporators in the so-called No Frost design, which means that with the help of an electric heater mounted on or near the tubular lamellar evaporator, the apparatus automatically defrosts the resulting frost or ice, which is subsequently known it takes the way out of the cell so that users of this type of refrigerating appliance do not have to worry about defrosting and removing the cut or ice from the cells.
Pri omenjenih rešitvah je potrebna hladilna moč cevno lamelnih uparjalnikov odvisna predvsem od velikosti hlajenih prostorov in pričakovane energijske učinkovitosti aparatov. Hladilno moč cevno lamelnega uparjalnika se povečuje predvsem s povečanjem njegovih zunanjih dimenzij. Pomanjkljivost tovrstnega povečevanja hladilne moči cevno lamelnih uparjalnikov leži v tem, da se s tem znatno zmanjša koristen volumen za shranjevanje živil v celici, kjer se cevno lamelni uparjalnik nahaja.In the mentioned solutions, the required cooling power of the tube-vaporizers depends mainly on the size of the refrigerated rooms and the expected energy efficiency of the appliances. The cooling power of the tubular blade evaporator is increased mainly by increasing its outer dimensions. The disadvantage of such an increase in the cooling capacity of tubular lamellar evaporators lies in the fact that this significantly reduces the useful volume for storing food in the cell where the tubular lamellar evaporator is located.
Povečanje hladilne moči hladilnih sistemov se bi lahko doseglo tudi z dodatnimi uparjalniki različnih izvedb na različnih mestih v ali okoli celice. Pomanjkljivost tovrstnih rešitev, zlasti pri No Frost izvedbah hladilnih aparatov, leži v tem, da bi se na teh dodatnih uparjalnikih in v njihovi okolici lahko nabiral srez ali led, ki bi ga moral uporabnik potem periodično odstranjevati, kar pomeni, da takšni hladilni aparati ne bi mogli biti deklarirani kot No Frost aparati.An increase in the cooling power of cooling systems could also be achieved with additional evaporators of different designs at different locations in or around the cell. The disadvantage of such solutions, especially with the No Frost refrigeration units, is that these additional evaporators and their surroundings could accumulate a cut or ice, which the user should then periodically remove, which means that such refrigeration appliances do not could be declared as No Frost appliances.
Naloga predloženega izuma je ustvariti izboljšani hladilni sistem hladilnega aparata, s katerim se bo odpravilo pomanjkljivosti znanih rešitev in sočasno povečati učinkovitost in ohraniti prijaznost uporabe hladilnega aparata.It is an object of the present invention to provide an improved refrigeration system for the refrigeration apparatus, which will eliminate the disadvantages of the known solutions and at the same time increase the efficiency and maintain the friendliness of the refrigeration appliance.
Zastavljena naloga je po izumu rešena s tem, da je cevno lamelni uparjalnik, ki je razporejen v notranjosti celice hladilnega aparata, hidravlično povezan z zunanjim uparjalnikom, ki je nameščen na zunanji strani celice. Zunanji uparjalnik je lahko zasnovan v različnih izvedbah, na primer kot cevni uparjalnik, ki na način navitja poteka po zunanjem obodu omenjene celice. Druga možna izvedba zunanjega uparjalnika je cevno ploščni uparjalnik, ki je nameščen na katerikoli stranici omenjene celice. Nadaljnja možna izvedba zunanjega uparjalnika je kanalsko ploščni oziroma t.i. roli bond uparjalnik, ki je nameščen na katerikoli stranici omenjene celice. Zunanji uparjalnik je lahko izveden tudi kot kombinacija katerikoli treh prej omenjenih izvedb.The object of the invention is solved by the fact that the tubular lamellar evaporator arranged inside the cell of the refrigeration unit is hydraulically connected to an external evaporator mounted on the exterior of the cell. An external evaporator may be designed in various embodiments, for example, as a tube evaporator, which winds its way around the outer circumference of said cell. Another possible embodiment of an external evaporator is a tubular plate evaporator which is mounted on any side of said cell. A further possible embodiment of an external evaporator is a ducted plate, or so. a roll bond evaporator mounted on any side of said cell. An external evaporator can also be designed as a combination of any of the three previously mentioned embodiments.
Omenjeni zunanji uparjalnik pri tem v celoti poteka v izolaciji omenjene celice. Po izumu je predvideno, da se omenjeni zunanji uparjalnik na celico namesti pred namestitvijo izolacije celice. Nadalje je po predlaganem izumu predvideno, da se omenjeni cevno lamelni uparjalnik namesti v hladilni aparat, ko je le-ta v celoti sestavljen, pri čemer se prosti konec omenjenega cevno lamelnega uparjalnika hidravlično poveže z v notranjost hladilnega prostora štrlečim prostim koncem omenjenega zunanjega uparjalnika.Said external evaporator is completely operated in isolation of said cell. According to the invention, it is intended that said external evaporator be mounted on the cell prior to the installation of cell isolation. It is further contemplated according to the present invention that said tubular lamellar evaporator be placed in the refrigeration apparatus when fully assembled, hydraulically connecting the free end of said tubular lamellar evaporator with the projecting free end of said external evaporator.
Izum je v nadaljevanju podrobneje opisan na osnovi neomejujočih izvedbenih primerov in s sklicevanjem na priloženo skico, kjer kaže sl. 1 hladilni aparat z lamelnim uparjalnikom in dodatnim zunanjim uparjalnikom v obliki navite cevi, sl. 2 hladilni aparat z lamelnim uparjalnikom in dodatnim zunanjim cevno ploščnim uparjalnikom.The invention will now be described in more detail with reference to non-limiting embodiments and with reference to the accompanying drawing, where FIG. 1 is a refrigerating apparatus with a lamellar evaporator and an additional external evaporator in the form of a coiled tube; FIG. 2 refrigerating apparatus with lamellar evaporator and additional external tube-plate evaporator.

Omenjeni uparjalnik oz. omenjena cev 9 je hidravlično povezana z omenjenim lamelnim uparjalnikom 3, pri čemer omenjena cev 9 skozi predor 7 v celici 1 prehaja skozi celico 1 in je hidravlično povezana z odvodno cevjo za hladivo lamelnega uparjalnika 3.3). The said evaporator or. said tube 9 is hydraulically connected to said lamellar evaporator 3, said tube 9 passing through cell 1 through a tunnel 7 and hydraulically connected to a coolant vapor outlet tube of the lamellar evaporator 3.
Po drugem izvedbenem primeru je predvideno, da je omenjeni uparjalnik zasnovan kot ploščni uparjalnik 10, ki je razporejen na zgornji zunanji stranici celice 1 (sl. 4). Čeprav je tako v opisu kot tudi na skicah opisan in prikazan le en uparjalnik, je po predlaganem izumu mogoča tudi izvedba, pri kateri je uporabljenih več enakovrstnih ali raznovrstnih zunanjih uparjalnikov, ki so razporejeni na vsaj eni stranici celice 1. Prosti konec 5 vsakokratnega zunanjega uparjalnika ali skupine več enakovrstnih ali raznovrstnih zunanjih uparjalnikov je speljan bodisi v kompresor bodisi v uparjalnik drugega prostora hladilnega aparata.According to another embodiment, it is provided that said evaporator is designed as a plate evaporator 10 arranged on the upper outer side of cell 1 (Fig. 4). Although only one evaporator is described and shown in the description and the drawings, according to the present invention, it is also possible to use several identical or different external evaporators arranged on at least one side of cell 1. The free end 5 of each external an evaporator or a group of several identical or diversified external evaporators is fed to either the compressor or the evaporator of another space of the refrigerating appliance.
Nadalje je po izumu predvideno, da se omenjeni zunanji uparjalnik namesti okoli omenjene celice 1 pred namestitvijo izolacije in pred sestavljanjem hladilnega aparata. Prav tako je predvideno, da se omenjeni cevno lamelni uparjalnik 3 namesti v hladilni aparat, ko je le-ta v celoti sestavljen.It is further contemplated according to the invention that said external evaporator be placed around said cell 1 before installing the insulation and before assembling the refrigeration apparatus. It is also envisaged that said tubular blade evaporator 3 be placed in the refrigeration apparatus when fully assembled.
Nadalje je po izumu predvideno, da je lahko zunanji uparjalnik razporejen neposredno na zunanji stran celice 1. Z namenom enakomernejše temperaturne porazdelitve po površinah celice in s tem povečanja učinkovitosti zunanjega uparjalnika 8, 10 ali zmanjšanja verjetnosti pojava rosenja oziroma sreženja na notranjih površinah celice 1 v področju zunanjega uparjalnika 8, 10, je po izumu nadalje predvideno, da je med celico 1 in zunanjim uparjalnikom 8, 10 nameščen material, ki služi kot toplotni izolator. Omenjeni toplotni izolator je namenjen višanju temperature na stenah celice 1 in s tem zmanjšanju možnosti pojava rosenja ali sreženja na notranjih površinah celice 1.It is further contemplated according to the invention that an external evaporator can be arranged directly on the outer side of cell 1. In order to distribute the temperature of the cells more evenly, thereby increasing the efficiency of the external evaporator 8, 10 or reducing the likelihood of dew or collapse on the inner surfaces of cell 1 in according to the invention it is further provided that a material is used between the cell 1 and the external evaporator 8, 10 to serve as a thermal insulator. Said thermal insulator is intended to increase the temperature on the walls of cell 1 and thereby reduce the possibility of dew or collapse on the inner surfaces of cell 1.
Kot nadgradnja je po izumu med celico 1 in zunanjim uparjalnikom predvidena namestitev kombinacije toplotno izolativnih materialov, da je temperatura na površinah celice 1 enakomerneje porazdeljena in višja, s čemer se zmanjša pojav rosenja ali sreženja na površini celice 1. Pri tem omenjena kombinacija toplotno izolativnih materialov obsega toplotno izolativne materiale različnih toplotnih prehodnosti in/ali toplotno izolativne materiale različnih debelin.According to the invention, a combination of thermally insulating materials is provided between the cell 1 and the external evaporator so that the temperature on the surfaces of cell 1 is evenly distributed and higher, thus reducing the occurrence of dew or shrinkage on the surface of cell 1. The combination of thermally insulating materials is mentioned. comprises thermal insulation materials of different thermal transmittances and / or thermal insulation materials of different thicknesses.
Na skicah prikazana izvedbena primera nista edina, z razumevanjem bistva izuma jih je možno izvesti tudi drugače. Tako je na primer mogoča izvedba, pri kateri je cevno ploščni uparjalnik 10 ali roli bond uparjalnik nameščen na hrbtni strani celice 1. Prednost tovrstne izvedbe leži v tem, da ni potrebno zmanjšati verjetnosti pojava rosenja ali sreženja, ker se notranje površine celice 1 na tem področju odtalijo s pomočjo grelnika na cevno lamelnem uparjalniku 3.The embodiments shown in the drawings are not the only ones; For example, it is possible to have an embodiment in which a tubular plate evaporator 10 or a roll bond evaporator is mounted on the back of cell 1. An advantage of this type is that there is no need to reduce the likelihood of dew or collision, since the inner surfaces of cell 1 on this the area is thawed by means of a heater on a tube-tube evaporator 3.
