Description

Regulacija hladilno zamrzovalnega aparataControl of the refrigerating freezer

Predmetni izum se nanaša na regulacijo hladilno zamrzovalnega aparata, zlasti hladilno zamrzovalnega aparata, obsegajočega le en kompresor, in ki je primerna za vzdrževanje temperature v zamrzovalnem prostoru aparata pri nizki okoliški temperaturi.The present invention relates to the regulation of a refrigerating freezer, in particular a refrigerating freezer comprising only one compressor, and which is suitable for maintaining the temperature in the freezer compartment of the apparatus at low ambient temperature.

Hladilno zamrzovalni aparati v gospodinjstvu se uporabljajo pri različnih temperaturah okolice. Pri običajnih okoliških temperaturah je čas delovanja in mirovanja kompresorja določen tako, da se ustrezne in zahtevane temperature doseže tako v hladilnem kot tudi v zamrzovalnem prostoru aparata. Težava pa se pojavi pri nizkih okoliških temperaturah, ko se potreba po hlajenju hladilnega prostora zmanjša. Zaradi tega kompresor deluje manj časa, posledično pa se dviga temperatura v zamrzovalnem prostoru aparata. To težavo se pri aparatih uvodoma omenjene vrste rešuje z dodatnim grelnikom, razporejenim v hladilnem prostoru aparata, pri čemer se omenjeni grelnik vklaplja bodisi ročno, s pomočjo termičnega stikala ali preko kompleksnega elektronskega vezja in mikroprocesorja, ki meri čas delovanja in mirovanja kompresorja. Pomanjkljivost vseh teh rešitev leži v tem, da bodisi ne odpravijo omenjenih težav ali pa so cenovno neugodne in zato neprimerne za gospodinjsko uporabo.Household refrigerators and freezers are used at different ambient temperatures. At normal ambient temperatures, the operating time and standstill of the compressor are determined in such a way that the appropriate and required temperatures are reached in both the cooling and freezing areas of the appliance. However, the problem arises at low ambient temperatures when the need for cooling the cooling compartment is reduced. As a result, the compressor runs less time and consequently the temperature in the freezer compartment rises. This problem is solved by an additional heater in the appliance of the aforementioned type, arranged in the appliance's cooling compartment, and the heater is switched on either manually, by means of a thermal switch or via a complex electronic circuit and microprocessor, which measures the compressor operation and standstill time. The disadvantage of all these solutions lies in the fact that they either do not solve the problems mentioned above, or are disadvantageous and therefore unsuitable for household use.

Naloga predloženega izuma je zasnovati takšno regulacijo hladilno zamrzovalnega aparata, ki bo odpravila pomanjkljivosti znanih rešitev.It is an object of the present invention to design such regulation of a refrigerating freezer that will eliminate the disadvantages of known solutions.

Enokompresorski hladilno zamrzovalni aparati, namenjeni gospodinjski uporabi, obsegajo dva medsebojno ločena in sočasno hlajena prostora, namreč hladilni prostor in zamrzovalni prostor.One-compressor refrigeration freezers intended for domestic use comprise two separate and simultaneously cooled spaces, namely a cooling space and a freezer compartment.

Da bi se v hladilno zamrzovalnem aparatu doseglo zahtevane temperature ne glede na temperaturo okolice, je po izumu predvideno, da se elektronskemu regulatorju sočasno dovaja vsakokratne vrednosti temperatur iz hladilnega prostora in neposredno od uparjalnika v hladilnem prostoru ter iz zamrzovalnega prostora. Pri prekoračitvi v zamrzovalnem prostoru nastavljene temperature se vklopi grelnik.In order to achieve the required temperatures in the refrigeration freezer, regardless of the ambient temperature, according to the invention, it is provided that the electronic controller be supplied simultaneously with the respective values of temperatures from the cooling compartment and directly from the evaporator in the cooling compartment and from the freezer compartment. When the setpoint temperature is exceeded, the heater switches on.

V hladilno zamrzovalnem aparatu je v hladilnem prostoru izbiroma razporejen tudi ventilator, ki se vklopi sočasno s kompresorjem.In the refrigerator-freezer, a fan is also arranged in the cooling compartment, which is switched on simultaneously with the compressor.

Z regulacijo po izumu se doseže posredno kontrolo temperature v zamrzovalnem prostoru na način, da se pri previsoki temperaturi zamrzovalnega prostora zniža za hladilni prostor nastavljeno temperaturo. Pri tem se grelnik vklaplja zgolj na osnovi dejanske temperature v zamrzovalnem prostoru, zaradi česar se zmanjša porabo energije.By regulation according to the invention, indirect control of the temperature in the freezer compartment is achieved in such a way that the set temperature is lowered by the freezer compartment too high. The heater is switched on only on the basis of the actual temperature in the freezer compartment, which reduces energy consumption.

V primeru neobičajne uporabe hladilno zamrzovalnega aparata, če uporabnik npr. pusti odprta vrata zamrzovalnega prostora, se pri previsoki temperaturi zamrzovalnega prostora vklopi grelnik v hladilnem prostoru, zaradi česar se vklopi kompresor, ki poskuša s podaljšanim delovanjem doseči ustrezno temperaturo v zamrzovalnem prostoru.In the case of unusual use of a refrigerating freezer, if the user e.g. Leaves the freezer compartment door open, the heater in the cooler compartment switches on when the freezer compartment temperature is too high, which causes the compressor to switch on to the desired freezer compartment by prolonged operation.

Izum je v nadaljevanju pobliže predstavljen na osnovi izvedbenega primera in s pomočjo priložene skice, kjer kaže sl. 1 shemo regulacije hladilno zamrzovalnega aparata po izumu.The invention will now be further described on the basis of an embodiment and with the help of the accompanying drawing, where FIG. 1 is a schematic diagram of a control of a refrigerating freezer according to the invention.

Hladilno zamrzovalni aparat obsega s predelno steno 1 medsebojno ločena prostora, in sicer hladilni prostor 2 in zamrzovalni prostor 3. Običajno je v območju spodnjega zadnjega dela omenjenega aparata razporejen kompresor 4, ki s hladilnim medijem preko kondenzatorja 7 in ustrezne kapilare oskrbuje uparjalnik 6 hladilnega prostora 2. Hladilni medij pri tem hladi hladilni prostor 2 na določeno temperaturo, tipično na +5°C, nakar omenjeni hladilni medij iz uparjalnika 6 nadaljuje pot v uparjalnik 5 zamrzovalnega prostora 3. Pri tem temperatura hladilnega medija na vstopu v uparjalnik 5 še vedno ustreza potrebam zamrzovalnega prostora 3, ki se ga hladi na določeno temperaturo, tipično na -18° C. Iz uparjalnika 5 potuje hladilni medij nazaj v omenjeni kompresor 4.The refrigerating freezer comprises, with partition 1, spaces separated from each other, namely the cooling compartment 2 and the freezer compartment 3. Typically, a compressor 4 is arranged in the region of the lower rear of said apparatus, which supplies the evaporator 6 of the cooling compartment with the cooling medium through the condenser 7 and the corresponding capillaries. 2. The cooling medium cools the cooling compartment 2 to a certain temperature, typically at + 5 ° C, after which said cooling medium from the evaporator 6 continues the path to the evaporator 5 of the freezer compartment 3. The temperature of the cooling medium at the inlet of the evaporator 5 still corresponds to the needs of the freezer compartment 3, which is cooled to a certain temperature, typically at -18 ° C. From the evaporator 5, the cooling medium flows back into said compressor 4.

V hladilnem prostoru 2 je razporejen grelnik 8, ki se ga po potrebi vklaplja, kar je podrobneje opisano v nadaljevanju. Nadalje je v hladilnem prostoru 2 razporejeno tipalo 9 hladilnega prostora, na uparjalniku 6 pa je razporejeno nadaljnje tipalo 10 uparjalnika. Še nadaljnje tipalo 11 zamrzovalnega prostora 3 je razporejeno v območju zamrzovalnega prostora 3. V hladilnem prostoru 2 je izbiroma razporejen še ventilator 12, ki po potrebi premika zračno maso v omenjenem hladilnem prostoru 2. Vsa omenjena tipala 9, 10, 11, grelnik 8, ventilator 12 in kompresor 4 so električni povezani z elektronskim regulatorjem 13, ki krmili delovanje kompresorja 4, grelnika 8 in ventilatorja 12, pri čemer so omenjene povezave na skici vsakokrat prikazane s črtkano črto.In the cooling compartment 2 there is a heater 8 which can be switched on if necessary, which is described in more detail below. Further, a cooling chamber sensor 9 is arranged in the cooling compartment 2 and a further evaporator sensor 10 is arranged on the evaporator 6. Still further sensor 11 of the freezer compartment 3 is arranged in the freezer compartment 3. In the cooling compartment 2, a fan 12 is optionally arranged, which, if necessary, displaces air mass in said refrigeration compartment 2. All of said sensors 9, 10, 11, heater 8, fan 12 and compressor 4 are electrically connected to an electronic controller 13 which controls the operation of the compressor 4, the heater 8 and the fan 12, each of which is shown in the drawing in each case with a dashed line.

Regulacija po izumu je pojasnjena na naslednjem primeru delovanja.The regulation of the invention is explained in the following example of operation.

Hladilno zamrzovalni aparat poskuša s pomočjo kompresorja doseči temperaturo, ki je nastavljena za hladilni prostor 2, medtem ko poskuša v zamrzovalnem prostoru 3 zagotoviti temperaturo, nižjo od npr. :15°C. Če je temperatura v hladilnem prostoru 2 višja od nastavljene temperature, ki je npr. +5° C, se vklopi kompresor 4. Kompresor 4 se izklopi, ko je temperatura v hladilnem prostoru 2 nižja od nastavljene temperature, ki je npr. +5°C. Minimalni čas prekinitve delovanja kompresorja 4 znaša pet minut. Prav tako znaša minimalni čas delovanja kompresorja 4 pet minut. V primeru, da je temperatura v hladilnem prostoru pod 0°C, se kompresor 4 izklopi.The refrigeration freezer attempts to reach a temperature set for the cooling compartment 2 by means of a compressor, while attempting to provide a temperature lower than e.g. Low : 16 ° C. If the temperature in the cooling compartment 2 is higher than the set temperature, e.g. + 5 ° C, compressor 4 switches on. Compressor 4 shuts off when the temperature in cooling compartment 2 is lower than the set temperature, e.g. + 5 ° C. The minimum shutdown time of compressor 4 is five minutes. The minimum operating time of the compressor 4 is also five minutes. If the temperature in the cooling compartment is below 0 ° C, compressor 4 shuts off.

Če je temperatura v hladilnem prostoru 2 enaka ali manjša od nastavljene temperature in je temperatura v zamrzovalnem prostoru 3 višja od npr. -15° C, regulator 13 vklopi grelnik 8. Omenjeni regulator 13 izklopi grelnik 8, ko temperatura v zamrzovalnem prostoru 3 pade pod npr. -15°C in temperatura v hladilnem prostoru 2 zraste nad nastavljeno temperaturo, npr. +5° C. Pri tem je potrebno poudariti, da se v primeru, ko je temperatura v zamrzovalnem prostoru višja od -15° C, prestavi tudi meja regulacije hladilnega prostora iz nastavljene temperature, ki znaša npr. +5°C, na novo temperaturo, ki znaša npr. +1 °C.If the temperature in the cooling compartment 2 is equal to or less than the set temperature and the temperature in the freezer compartment 3 is higher than e.g. -15 ° C, controller 13 switches on the heater 8. Said controller 13 switches off the heater 8 when the temperature in the freezer compartment 3 drops below e.g. -15 ° C and the temperature in the cooling compartment 2 rises above the set temperature, e.g. It should be noted that when the temperature in the freezer compartment is higher than -15 ° C, the limit of regulation of the cooling compartment from the set temperature is set, eg. + 5 ° C, to a new temperature of e.g. 1 ° C.

Na tak način se pri nastavitvi temperature hladilnega prostora 2 na +1°C v zamrzovalnem prostoru 3 doseže temperaturo, nižjo od -18°C, ne glede na okoliško temperaturo. To je zlasti pomembno pri nizkih temperaturah okolice, ko so hladilne potrebe hladilnega dela hladilno zamrzovalnega aparata majhne, pri čemer se z nastavitvijo temperature hladilnega prostora 2 na +1 ° C kompresor 4 prisili v daljše delovanje. Če zaradi nizke okoliške temperature ta čas ni dovolj dolg, se zaradi segretja zamrzovalnega prostora 3 nad -18°C vklopi grelnik 8, ki segreva hladilni prostor 2, s čimer se doseže dvig temperature v hladilnem prostoru 2 in posledično podaljšano delovanje kompresorja 4.In this way, when the temperature of the cooling compartment 2 is set to + 1 ° C, the freezer compartment 3 achieves a temperature lower than -18 ° C, regardless of the surrounding temperature. This is especially important at low ambient temperatures, when the cooling needs of the refrigeration unit are small, forcing the compressor 4 to operate for longer by adjusting the cooling room temperature 2 to +1 ° C. If this time is not long enough due to the low ambient temperature, the heater 8 is heated due to the heating of the freezer compartment 3 above -18 ° C, which results in a rise in the temperature in the cooling compartment 2 and the consequent prolonged operation of the compressor 4.

Prednost regulacije po izumu leži v tem, da se grelnik 8 vklopi le tedaj, ko se v zamrzovalnem prostoru 3 temperatura dvigne nad nastavljeno. Seveda pa to pomeni, da se v primeru, ko je temperatura v hladilnem prostoru 2 nastavljena na +1°C, v zamrzovalnem prostoru doseže temperaturo, nižjo od -18°C in to ne glede na okoliško temperaturo. Če je temperatura okolice zadosti visoka, je že zaradi potreb hladilnega prostora 2 čas delovanja kompresorja 4 zadosti dolg, da se v zamrzovalnem prostoru 3 doseže zadosti nizko temperaturo, ne da bi bilo potrebno vklopiti grelnik 8.An advantage of the regulation according to the invention is that the heater 8 is switched on only when the temperature in the freezer compartment 3 rises above the set point. Of course, this means that when the temperature in the cooling compartment 2 is set to + 1 ° C, it reaches a temperature lower than -18 ° C in the freezer compartment, regardless of the surrounding temperature. If the ambient temperature is high enough, due to the needs of the cooling compartment 2, the operating time of the compressor 4 is long enough to reach a sufficiently low temperature in the freezer compartment 3 without having to switch on the heater 8.
