800765743 En del 25 av tryckledningen ll, som är ansluten till grenpunkten 14, är riktad nedåt mot denna punkt, och ledningen 20 till magnetventilen 21 är belägen under grenpunkten medan den andra till grenpunkten 14 anslutna ledningen 15 åtminstone vid anslutnings- stället är horisontell eller uppåtriktad från grenpunkten. Strypningen 22 i ledningen till kylevaporatorn 23 är kraftigare än strypningen i kapillären 16 till frysevaporatorn 17. När systemet arbetar och ventilen 21 är öppen, kommer därför köldmediekondensat att tillföras båda evaporatorerna. Strypningen i kapillären 22 är sådan att inte allt från kompressorn kommande köldmedium kan passera igenom. Istället samlas en del kondensat över' venti- len 21 i ledningen 20 åtminstone upp till grenpunkten 14. Härigenom kommer båda evapora- K torerna att försörjas med köldmediekondensat och att arbeta effektivt vid behov av kylning i respektive kammare i kylmöbeln, och det är möjligt att undvika perioder under vilka det föreligger kylbehov i en kammare men dess evaporator tillföras enbart köldmedieanga eller en blandning av köldmedieånga och köldmediekondensat med en dålig kylning som följd. 7 Patentkrav _ 'A part 25 of the pressure line 11, which is connected to the branch point 14, is directed downwards towards this point, and the line 20 to the solenoid valve 21 is located below the branch point while the other line 15 connected to the branch point 14 is horizontal or upward at least at the connection point from the branch point. The choke 22 in the line to the cooling evaporator 23 is stronger than the choke in the capillary 16 to the freezing evaporator 17. When the system is operating and the valve 21 is open, therefore refrigerant condensate will be supplied to both evaporators. The throttle in the capillary 22 is such that not all of the refrigerant coming from the compressor can pass through. Instead, some condensate collects over the valve 21 in the line 20 at least up to the branch point 14. As a result, both evaporators will be supplied with refrigerant condensate and work efficiently when cooling is required in the respective chamber in the cooling unit, and it is possible to avoid periods during which there is a cooling need in a chamber but its evaporator is supplied only with refrigerant vapor or a mixture of refrigerant vapor and refrigerant condensate with a poor cooling as a result. 7 Claims _ ' 1. l. Anordning vid en kylmöbel med ett kompressor-system som har en evaporator för en kylkammare och en evaporator för en fryskammare, ett kapillärrör före fryskammarens evaporator och ett kapillärrör ochuen magnetventil före kylkammarens evaporator, varvid de båda kapillärrören är anordnade parallellt i systemet och magnetventilen är belägen uppströms om det anslutna kapillärröret, varjämte ledningen från kondensorn har en grenpunkt, från vilken ledningar går till de två kapillärrören, k ä n n e t e c k n a d därav, att grenpunkten (14) och grenledningarna (15,20) är så anordnade med ventilen (21) under grenpunkten (14) i en nedåtgående ledning (20) och strypningen genom kapillären (22) i ledningen (21) till kylkammarens evaporator (23) så avpassad till den andra strypningen (16), ' att då kompressorn (10) arbetar och ventilen (21) är öppen, en viss mängd köldmedie- kondensat samlas i ledningen (20) före ventilen (21).1. A device for a refrigeration unit with a compressor system having an evaporator for a cold chamber and an evaporator for a freezing chamber, a capillary tube before the freezing chamber evaporator and a capillary tube and a solenoid valve before the cooling chamber evaporator, the two capillary tubes being arranged parallel in the system and the solenoid valve is located upstream of the connected capillary tube, and the conduit from the condenser has a branch point, from which conduits go to the two capillary tubes, characterized in that the branch point (14) and the branch conduits (15,20) are so arranged with the valve ( 21) below the branch point (14) in a downward line (20) and the restriction through the capillary (22) in the line (21) to the evaporator (23) of the cooling chamber so adapted to the second restriction (16), that when the compressor (10) operates and the valve (21) is open, a certain amount of refrigerant condensate collects in the line (20) before the valve (21). 2. Anordning enligt patentkravet 1, k ä n n e t e c k n a d därav, att 'grenledningens (15) mot frysevaporatorn (17) gående del vid grenpunkten (14)är horisontell eller riktad över horisontalplanet genom punkten (14). qDevice according to claim 1, characterized in that the part of the branch line (15) towards the freezing evaporator (17) at the branch point (14) is horizontal or directed over the horizontal plane through the point (14). q 3. Anordning enligt patentkravet l, k ä n n e t e c k n a d därav, att strypningen i led- ningen (20) till kylevaporatorn (23) är sådan, att kondensat samlas före ventilen (21) åtminstone ända till grenpunkten (14).Device according to claim 1, characterized in that the throttle in the line (20) of the cooling evaporator (23) is such that condensate collects before the valve (21) at least all the way to the branch point (14). 4. Anordning enligt patentkravet 1, k ä n n e t e c k n a d därav, att strypningen i led- ningen (20) till kylevaporatorn (23) är -kraftigare än strypningen (16) i ledningen (15) till frysevaporatorn (17).Device according to claim 1, characterized in that the throttle in the line (20) of the cooling evaporator (23) is more powerful than the throttle (16) in the line (15) of the freezing evaporator (17).
