Description

Kältethermostat Die Erfindung betrifft einen Kältethermostaten, bei dem zwei Einspritzleitungen für einen Verdampfer mit Je einem Drosselorgan - thermostatischen Expansionsventil, fest eingestellte Drossel - vorhanden sind nach Patentanmeldung P 2o 29 4o3.5.Cold thermostat The invention relates to a cold thermostat at the two injection lines for an evaporator, each with a throttle element - thermostatic Expansion valve, fixed throttle - available according to patent application P 2o 29 4o3.5.

Gegenstand der Hauptanmeldung ist ein Kältethermostat, mit dem die Temperierflüssigkeit eines Bad- und/oder Umwälzthermostaten abgekühlt werden kann. Dieser Kältethermostat arrbreitet mit zwei verschiedenen Einspritzleitungen für den Verdampfer. Im Ausführungsbeispiel wird die parallele Anordnung einer fest eingestellten Drossel und eines thermostatischen Expansionsventils gezeigt. Dieoc geschilderte Anordnung hat den Nachteil, daß zur Verhinderung deß Entstehens von Flüssigkeitsschlägen und des Absinkens der Saugleistung des Kompressors unter di. Durchflußleistung der fest eingestellten Drossel ein Druckwächter vorhanden sein muß, der den Kältethermostaten beim Unterschreiten eines bestimmten Mindestsaugdruokes abschaltet.The main application is a cooling thermostat with which the Tempering liquid of a bath and / or circulation thermostat can be cooled. This cooling thermostat arrbreit with two different injection lines for the vaporizer. In the exemplary embodiment, the parallel arrangement is a permanently set Throttle and a thermostatic expansion valve shown. Dieoc described Arrangement has the disadvantage that to prevent the occurrence of liquid hammer and the decrease in the suction power of the compressor below di. Flow rate of fixed throttle, a pressure switch must be available to control the cooling thermostat switches off when falling below a certain minimum suction pressure.

Es wurde gefunden, daß der Kältethermostat auch mit den gleichen Vorteilen filr das AbkUhlen der Temperierflüssigkeit eines Bad- und/oder Umwälzthermostaten benutzt werden kann, wenn das thermostatische Expansionsventil und die fest eingestellte Drossel nicht so, wie im Ausführungsbeispiel der Patentanmeldung P 20 29 403.5 aufgezeigt, angel ordnet werden, sondern das thermostatische Expaneionsventil hinter der fest eingestellten Drossel angeordnet wird und damit der Druckwächter entfallen kann.It has been found that the refrigerated thermostat also offers the same advantages for cooling down the bath and / or circulation thermostat can be used when the thermostatic expansion valve and the fixed Throttle not as shown in the exemplary embodiment of patent application P 20 29 403.5, angel, but the thermostatic expansion valve behind the fixed adjusted throttle is arranged and thus the pressure monitor can be omitted.

Die Erfindung soll nachstehend an einem AusfUhrungsbeispiel näher erläutert werden. In der zugehörigen Zeichnung ist die Darstellung des Kältethermostaten nach der Hauptpatentanmeldung derart ergänzt, daß sie die Erfindung nach der vorliegenden Beschreibung enthält0 D.emgemEß wurden die gleichen Bezugszeichen verwendet.The invention is to be described in more detail below using an exemplary embodiment explained. In the accompanying drawing is the representation of the cooling thermostat according to the main patent application so supplemented that they the invention according to the present Description contains 0 D. Accordingly, the same reference numbers have been used.

Das thermostatisohe Expansionsventil 9 wird hinter der fest eingestellten Drossel 8 und dem Magnetventil 7 angeordnet.The thermostatic expansion valve 9 is set behind the fixed Throttle 8 and the solenoid valve 7 are arranged.

Da das thermostatische Expansionsventil 9 die Überhitzung der Kältemitteldämpfe in der Saugleistung regelt, wird das Uberfluten des Verdampfers 3 verhindert.Because the thermostatic expansion valve 9 prevents the overheating of the refrigerant vapors regulates the suction power, the flooding of the evaporator 3 is prevented.
