Description
Predchladzovač skvapalneného chladivá a pomocného plynu absorpčně difúznej chladiacej aparatúry pozostáva z predíženej rúry výparníka, predíženej rúry pomocného plynu, odvádzacej rúry páry chladivá a z kvapalinovej chladivovej rúry. Na začiatku predchladzovača je otvor na výstup pomocného plynu do medzikružia tvoriacej rúry z predíženej časti výparníkovej rúry a rúry pomocného plynu. V mieste otvoru je připojená kvapalinová chladivová rúra, ktorá je pozdížne, teplovodně spojená s predíženou častou výparníkovej rúry. V predchladzovači sa značné podchadí kvapalné chladivo a pomocný plyn prúdiaci do výparníka, čím sa docielí nízká vyparovacia teplota v nízkoteplotnom výparníku.The precooler of the liquid refrigerant and auxiliary gas of the absorption diffusion cooling apparatus consists of an elongated evaporator tube, an elongated auxiliary gas tube, a refrigerant vapor outlet tube and a liquid refrigerant tube. At the beginning of the precooler there is an opening for the outflow of auxiliary gas into the annular forming tube from the extended portion of the evaporator tube and the auxiliary gas tube. A liquid coolant tube is connected at the aperture, which is longitudinally connected to the elongated portion of the evaporator tube. In the precooler, the liquid coolant and auxiliary gas flowing into the evaporator are largely under-cooled, thereby achieving a low evaporation temperature in the low temperature evaporator.
Vynález sa týká predchladenia skvapalneného chladivá a pomocného plynu před vstupom do výparníka absorpčně difúznej chladiacej aparatúry.The invention relates to the precooling of a liquid refrigerant and an auxiliary gas prior to entering the evaporator of an absorption diffusion cooling apparatus.
Skvapalnené chladivo opúšťajúci kondenzátor ako i pomocný plyn opúšťajúci absorbér majú poměrně vysokú teplotu, čo bráni íntenzívnemu vyparovaniu. Z uvedeného důvodu je nutné ich predchladiť před prúdením do výparníka.The liquid refrigerant leaving the condenser and the auxiliary gas leaving the absorber have a relatively high temperature, which prevents intense evaporation. For this reason, it is necessary to pre-cool them before flowing into the evaporator.
U známých chladiacich aparatur predchladenie sa deje pomocou plynových výmenníkov tepla využitím studenej páry, ktoré opúšťajú výparník. Nedostatok tohoto riešenia spočívá v tom, že tieto páry už nemajú dost nízku teplotu a nedostatečné predchladia skvapalnené chladivo a pomocný plyn.In the known cooling apparatus, the pre-cooling takes place by means of gas heat exchangers utilizing cold steam leaving the evaporator. The disadvantage of this solution is that these vapors no longer have a low enough temperature and insufficiently pre-cool the liquid refrigerant and auxiliary gas.
U niektorých aparatúr predchladenie skvapalneného chladivá sa riešie pomocou páry získané vypařováním chladivá hned' za kondenzátorom. Nevýhodou tohoto prevedenia je, že nedostatočne sa predchladzuje pomocný plyn a praktická realizácia je náročná.In some apparatuses, the precooling of the liquefied refrigerant is solved by the steam obtained by evaporating the refrigerant immediately after the condenser. The disadvantage of this embodiment is that the auxiliary gas is not sufficiently pre-cooled and the practical implementation is difficult.
Vyššie uvedené nedostatky odstraňuje predchladzovač skvapalnného chladivá a pomocného plynu absorpčně difúznej chladiacej aparatúry podfa vynálezu, ktorého podstatou je, že predížená časť rúry s neutrálnym plynom, ktorá má na obvode otvor, je vsunutá do predlženej časti výparníka, ku ktorej je připojená odvádzacia rúra páry chladivá a kvapalinová chladivová rúra.The above-mentioned drawbacks are overcome by the liquid refrigerant and auxiliary gas pre-cooler of the absorption diffusion refrigeration apparatus of the invention, which is characterized in that the elongated portion of the neutral gas tube having an opening at the periphery is inserted into the elongated portion of the evaporator to which the refrigerant steam pipe is connected. and a liquid coolant tube.
V medzikruží oboch rúr nastane čiastočné vyparovanie a silné predchladenie skvapalneného chladivá a pomocného plynu prúdiacich do nízkoteplotného výparníka. V pradchladzovači vzniklé páry neprúdia do výparníka nízkoteplotného priestoru, ale sú odvádzané do plynového výmenníka.Partial evaporation and strong pre-cooling of the liquid refrigerant and auxiliary gas flowing into the low-temperature evaporator will occur in the annulus of both tubes. The vapors produced in the supercooler do not flow into the evaporator of the low temperature space, but are discharged to the gas exchanger.
Ďalšou výhodou tohoto riešenia je v tom, že stačí nepatrný výškový rozdiel medzi kondenzátorom a výparníkom, čo umožňuje výhodné usporiadanie nízkoteplotného a hlavného priestoru chladničky.A further advantage of this solution is that a slight height difference between the condenser and the evaporator is sufficient, which allows for an advantageous arrangement of the low temperature and main compartment of the refrigerator.
Na pripojenom výkrese je znázorněný predchladzovač skvapalneného chladivá a pomocného plynu.The attached drawing illustrates a precooler for liquefied refrigerant and auxiliary gas.
Vypudené páry chladivá vo varníku 16 prúdia cez deflegmátor 1 do kondenzátora 2, kde sa skvapalňujú. Chladivo tečie do kvapalinovej rúry 3, ktorá je teplovodně spojená s predíženou častou 4 výparníka 7, vtéká do nej a vypařuje sa. Casť pomocného plynu z rúry 5 prúdi do rúry 4 cez otvor 6 a difundujú do nej páry chladivá. Převážná časť pomocného plynu a kvapalného chladivá prúdi do nízkoteplotného výparníka 7. Vypařováním v predchladzovači sa ochladzujú pomocný plyn v rúre 5 a kvapalné chladivo v rúre 3. Páry chladivá z predchladzovača sú odvedené rúrou 8 mimo predchladzovač a nízkoteplotný výparník 7. V priereze I—I prúdi do výparníka 7 dobře predchladené kvapalné chladivo a pomocný plyn, čím sa docielí nízká vyparovacia teplota vo výparníku 7. Kvapalné chladivo, páry a pomocný plyn prúdia cez prvý stupeň plynového výmenníka 9 do výparníka 11 hlavného priestoru, kde nastáva cfalšie vyparovanie. Vzniklé páry prúdia cez plynový výmenník 12 a dochladzovač 15 do absorbéra. Z absorbéra prúdi čistý pomocný plyn zbavený chladivových pár v rúre 14 cez plynový výmenník 12 a v rúre 13 pomocného plynu opář do predchladzovača a cyklus sa znovu opakuje. V rúre 13 sa nachádza tiež neutrálny plyn, ktorý slúži na vyrovnáváme celkového tlaku v chladiacej aparatúre.The expelled vapor of refrigerant in the boil 16 flows through the deflegmator 1 to the condenser 2 where it is liquefied. The coolant flows into the liquid pipe 3, which is heat-connected to the extended part 4 of the evaporator 7, flows into it and evaporates. A portion of the auxiliary gas from the pipe 5 flows into the pipe 4 through the opening 6 and the refrigerant vapor diffuses into it. The bulk of the auxiliary gas and the liquid coolant flows into the low temperature evaporator 7. Evaporation in the precooler cools the auxiliary gas in the oven 5 and the liquid refrigerant in the oven 3. The refrigerant vapor from the precooler is discharged through the oven 8 outside the precooler and low temperature evaporator I. well-cooled liquid refrigerant and auxiliary gas flow into the evaporator 7 to achieve a low evaporation temperature in the evaporator 7. Liquid refrigerant, vapors and auxiliary gas flow through the first stage of the gas exchanger 9 to the main compartment evaporator 11, where the fumes evaporate less. The resulting vapors flow through the gas exchanger 12 and the aftercooler 15 into the absorber. From the absorber, pure coolant-free gas flows in the pipe 14 through the gas exchanger 12 and in the auxiliary gas pipe 13 into the precooler and the cycle is repeated again. There is also a neutral gas in the oven 13, which serves to equalize the total pressure in the cooling apparatus.
Predchladzovač je vytvořený tak, že rúra 5 je vsunutá do rúry 4. Koniec rúry 4 je připojený k rúre 5. Rúra 3 je teplovodpe spojená s rúrou 4 a jeden koniec ústi do nej pri jej konci. Naproti pripojenia rúry 3 k rúra 4 je otvor S na rúre 5. K hornej polovici rúry 4 blízko konca rúry 5 je připojená rúra 8, ktorej druhý koniec je připojený k vonkajšej rúre plynového výmenníka 9. Koniec rúry 5 je čiastočné rozšířený. Všetky spomínané připojena sú převedená plynotesným zvarom.The precooler is formed so that the pipe 5 is inserted into the pipe 4. The end of the pipe 4 is connected to the pipe 5. The pipe 3 is thermally connected to the pipe 4 and one end opens into it at its end. Opposite the connection of the pipe 3 to the pipe 4 is an opening S on the pipe 5. To the upper half of the pipe 4 near the end of the pipe 5 is connected a pipe 8, the other end of which is connected to the outer pipe of the gas exchanger 9. All the above-mentioned connections are transferred by gas-tight weld.
