Beschreibung HaushaitkühlschrankDescription Household refrigerator
Die vorliegende Neuerung bezieht sich auf Haushaitkälteschränke mit FCKW-freier Isolierung, die universell zum Aufbewahren von Speisen und Getränken im Haushalt eingesetzt werden.This innovation relates to household refrigerators with CFC-free insulation, which are universally used for storing food and drinks in the home.
Diese Gerate sind allgemein bekannt, und der technische Stand dieser Geräte ist dem erwartenden Komfort und der funktioneilen Leistung entsprechend hoch. Dies ist auch ein wesentlicher Faktor zur Preisbildung der Geräts. Entsprechend der allgemeinen Nachfrage und der Notwendigkeit des Einsatzes für Jedermann mußten entsprechende Werkstoffe für eine hochtechnologisierte Fertigung bereitgestellt werden. Dies traf und trifft besonders für die Stoffe des Kältemittels zu.These devices are well known and the technical level of these devices is high in line with the expected comfort and functional performance. This is also a key factor in determining the price of the device. In line with general demand and the need for everyone to use them, appropriate materials had to be made available for high-tech production. This was and is particularly true for the coolant materials.
Geräte der jetzigen Fertigung haben einen entscheidenden Nachteil, der immer wieder und jetzt besonders Anlaß zur Besorgnis gibt. Der Einsatz von FCKW- und FKW-Kältemittel wird zur Problemzone eines umweltbewußt denkenden Bürgers.Devices manufactured today have a crucial disadvantage, which is a cause for concern time and again, and is particularly so now. The use of CFC and HFC refrigerants is becoming a problem area for environmentally conscious citizens.
Der Neuerung liegt die Aufgabe zugrunde, ein Kältemittel vorzuschlagen, das neben den gewünschten Stoffeigenschaften auch völlig umweltverträglich ist.The innovation is based on the task of proposing a refrigerant that, in addition to having the desired material properties, is also completely environmentally friendly.
Ein Kältemittel dieser Gattung wird erreicht, indem man eine Mischung aus Propan R 290 und Isobutan R 600 a herstellt. Dabei ist das Mischungsverhältnis so einzustellen, daß der Anteil jedes Partners ZZ % bis 50 % betragen kann.A refrigerant of this type is obtained by producing a mixture of propane R 290 and isobutane R 600 a. The mixing ratio is adjusted so that the proportion of each partner can be ZZ % to 50 %.
Die Vorteile dieser Neuerung liegen in einer völligen Umweltverträglichkeit des Kältemittels. Bei Einsatz dieses Kältemittels in einem Kälteschrank der eingangs genannten Art ist somit ein total FCKW- und FKW-freier Kälteschrank auf dem Markt.The advantages of this innovation lie in the fact that the coolant is completely environmentally friendly. When this coolant is used in a refrigerator of the type mentioned above, a completely CFC and HFC-free refrigerator is available on the market.
