Description

Ili Kiilteanlagetl wird die Zufuhr des flüssigen K;ilteinittels zum Verdampfer häufig durch ver- rlainlrferseitig angeordnete Schwininierregler ge- regelt. Diese Regler gehen die Zufuhr an Kälte- mittel frei, wenn der Spiegel im Verdampfer unter einen bestimmten Stand sinkt, und drosseln die 1Lqlteniittelzuftilir, wenn er über einen bestimmten Staild ansteigt. "('ritt in derartigen Kälteanlagen eine Verknap- pung an lt;iltemittel auf, so wird der Schwimmer- regler verhältnismäßig häufig und sehr lange oder sogar (lauernd o5ffnen. Dadurch wird auch der Ver- tliissiger ganz oder nahezu entleert, so daß außer (lern flüssigen Kältemittel auch größere Mengen an Kältemittel dampfförmig in den Verdampfer langen. wodurch die Wirtschaftlichkeit der _An- lage- wesentlich herabgesetzt wird. In solchen Fällen kann man :ich zwar zuweilen dadurch helfen. daß :nan statt des verdattipferseitig angeordneten einen krmdensatoirseitig angeordneten Schwimmerregler verwen (iet. Indessen ist diese :.Maßnahme nicht überall anwendbar. Sie versagt beispielsweise, wenn mehrere Verdampfer von einem Verflüssige her parallel finit Kältemittel versehen werden inüsseil. Zur Steuerung der Füllung lassen sielt in diesem all verdainpferseitig angeordnete Schwimmer- regler flicht umgehen. L rin nun die eingangs erwähnten N acliteile zu ver- ineiden, die hei der Verknappung der Füllung ein- treten. wird gemäß der Erfindung außer dem oder den wcr(iainl)ferseitig angeordneten Schwimmer- reglern zusätzlich noch ein kondensatorseitig an- @e(@rrlneter -7,cli%wiiiinierregler verwendet, dessen l)tirclitrittsöfftititig größer ist als die aller ver- (lanipferseitig angeordneten Schwimmerregler zu- s<ti11111e11. Ist die Kälteanlage reichlich mit Kältemittel ge- füllt. so( wird stets so viel flüssiges Kältemittel ini Verflüssige( anwesend sein, daß der kondensator- seitige Schwimmerregler dauernd öffnet. Bei seiner verhältnismäßig großen Ausflußöffnung drosselt er (las Kältemittel kaum und die Anlage arbeitet so, als ob lediglich ein verdatnpferseitig angeordneter Schwitninerregler vorhanden wäre. Tritt jedoch li<ilteniitteltnaligel ein und droht eine Entleerung (1 es Verflüssigers. >o wird der kondensatorseitig singeordnete Sehwininierregler durch rechtzeitiges Schliefen dafür sorgen. dall) stets soi viel flüssiges Kältemittel im Verflüssige( (>leibt. (iaß kein Durch- schlagen des Kälteinitteldampfes stattfinden kann. Die Abbildung zeigt eine Anordnung, in der der Erfindungsgedanke verwirklicht ist. In der Abbil- dung bezeichnet r einen Verdichter, der <las ver- dichtete Kältemittel in den Verflüssige( 2 drückt, wo es kondensiert. Das flüssige Kältemittel gelangt vorn Verflüssige( in die Saniinelflasche 3, in der der Regler mit Schwimmer 4 angeordnet ist. Der Drehpunkt des Scliwininieri-eglers ist mit t; be- zeichnet. Der Ventilkegel (1 liebt sich und gibt da- mit den Ausfluß frei, wenn der Stand in der SarnmeIflasche eine gewisse Höhe erreicht hat und umgekehrt. Das flüssige Kältemittel gelangt bei offenemcl@winnnerregler durch (fit- verhältnis- mäßig große Ausflußöffnung j und (las Rohr t; in (las Gehäuse des verdampferseitigen Regler: finit Schwimmer g. Der Drehpunkt dieses Schwimmer- reglers liegt hei to, so daß sich der Ventilkegel t t lebt und den Zufluß freigibt, wenn der Spiegel im Gehäuse sinkt und umgekehrt. Das flüssig(, Kältemittel gelangt dann durch dieverhältnisinäßig kleine Einflußöffnung 12 und das Rohr 13 frs den Verdampfer 14. Ani Ende (les Verdampfers i-1 1>e- findet sich in üblicher Weise ein Flüssigkeits- abscheider 15, der (las mit Dainpf mitgerisselie flüssige Kältemittel durch die Falleitung 16 in den Verdampfer i.l zurückführt, so dali der Kältemittel- dampf durch Leitung t; (Je", \`erdichter trocken zugeführt ,werden kann. Mit i<S ist eine Ent- gasungsleitting für (las schwiniinergehätise be- zeichnet. Ili Kiilteanlagetl is the supply of the liquid Cooling to the evaporator often by means of vibration regulators arranged on the relay side regulates. These regulators feed the refrigeration medium free when the level in the evaporator is below drops to a certain level, and throttle the 1Lqlteniittelzuftilir if he has a certain Staild increases. "('In such refrigeration systems there was a shortage pung at the oil, the float regulator relatively often and very long or even (open lurking. This also more diligent completely or almost completely emptied, so that besides (also learn larger quantities of liquid refrigerants of refrigerant in vapor form into the evaporator long. whereby the profitability of the _An- location is significantly reduced.
