Description
Verfahren zum Kühlen von. Schleuderverdichtern in Wärmepumpenverfahren.Method of cooling. Centrifugal compressors in heat pump processes.
Es ist bekannt, Verdichter zu kühlen, um die Verdichtungsarbeit zu verringern. Werden kondensierbare Dämpfe verdichtet, so ist die Verdichtungstemperatur möglichst in der Nähe der dem Druck entsprechenden Verdampfungstemperatur zu halten. Bei den zur Verdichtung von Brüdendämpfen verwandten sogenannten Wärmepumpen geschah diese Kühlung bisher auf verschiedene Art, und zwar durch gewöhnliche Wasserkühlung in Oberflächenkühlern, durch Einspritzen von Kühlflüssigkeit in den Verdichter oder durch Herausführen der zu verdichtenden Dämpfe je am Ende mehrerer Stufen und Abgabe der Überhitzungswärme an die einzudampfende Flüssigkeit. Mit diesen Verfahren sind gewisse Nachteile verbunden. Bei der gewöhnlichen Kühlung in Oberilächenkühlern geht die abzuführende Wärmemenge für den Wärmepumpenkreislauf verloren. Bei Einspritzkühlung gelingt es meist nicht, die eingespritzte Kühlflüssigkeit gleichmäßig genug zu verteilen und rasch genug zu verdunsten. Das Herausführen der zu verdichtenden Dämpfe bedingt umfangreiche Rohrleitungen, Unterteilung und unwirtschaftliche Vergrößerung der Eindampfgefäße usw. It is known to cool compressors in order to do the compression work to decrease. If condensable vapors are compressed, the compression temperature is as close as possible to the evaporation temperature corresponding to the pressure. In the case of the so-called heat pumps used to compress vapor vapors, this happened this cooling so far in different ways, namely by ordinary water cooling in surface coolers, by injecting cooling liquid into the compressor or by leading out the vapors to be compressed at the end of several stages and discharging them the superheating heat to the liquid to be evaporated. With these procedures are associated with certain disadvantages. With normal cooling in surface coolers the amount of heat to be dissipated for the heat pump circuit is lost. With injection cooling it is usually not possible to distribute the injected coolant evenly enough and evaporate quickly enough. The removal of the vapors to be compressed is necessary extensive pipelines, subdivision and uneconomical enlargement of the Evaporation vessels etc.
Alle diese Nachteile sollen durch die vorliegende Erfindung behoben werden, die sich jedoch ausdrücklich nur auftSchleuderverdichter bezieht. Sie besteht darin, daß als Kühlflüssigkeit die einzudampfende Flüssigkeit selbst verwandt wird, die durch Oberflächenkühler bekannter Ausführung hindurchgepreßt und dann in die Verdampfungsgefäße geleitet wird. Dort dient diese nun vorgewärmte Flüssigkeit als Ergänzung der bereits verdampften Flüssigkeit. Die zum Zwecke der Kühlung aus dem Verdichter abgeführte Wärmemenge bleibt somit dem Wärmepumpenkreislauf vollständig erhalten. Bei Vorhandensein mehrerer Kühler an einem Verdichter kann die Kühlflüssigkeit sämtliche Kühler hintereinander durchßießen, oder es können mehrere oder sämtliche Kühler parallel geschaltet sein. Es kann dieselbe Kühlflüssigkeit die Kühler auch mehrmals durchlaufen. All of these disadvantages are intended to be remedied by the present invention which, however, expressly only refers to centrifugal compressors. she consists in that the liquid to be evaporated is used as the cooling liquid itself, pressed through the surface cooler of known design and then into the Evaporation vessels is conducted. There this preheated liquid serves as a Supplement to the liquid that has already evaporated. For the purpose of cooling from the The amount of heat dissipated from the compressor therefore remains in full in the heat pump circuit obtain. If there are several coolers on one compressor, the cooling liquid all coolers one after the other, or several or all of them Cooler must be connected in parallel. The cooler can also use the same coolant go through several times.
Wo Niederschläge aus der einzudampfenden Flüssigkeit im Kühler zu gewärtigen sind, sind die Kühler zweckmäßigerweise so einzurichten, daß sie leicht - und möglichst ohne Betriebseinstellung gereinigt werden können.Where there is precipitation from the liquid to be evaporated in the cooler are expected, it is advisable to set up the cooler so that it is light - and can be cleaned, if possible, without stopping operations.
