Abstract

Es wird ein Warenpräsentationsmöbel mit wenigstens zwei Verdampfern und Flüssigkeits- und Saugleitungen, über die den Verdampfern ein Kältemittel(gemisch), das aus einer Kältemittel(gemisch)versorgungseinrichtung stammt, zugeführt oder von diesen abgeführt wird, beschrieben.It will be a product display unit with at least two evaporators and Liquid and suction lines through which the evaporators use a refrigerant (mixture), that comes from a refrigerant (mixture) supply device, supplied or from this is discharged.

Erfindungsgemäß sind die Verdampfer (V, V', V", V"') über eine gemeinsame Flüssigkeitsleitung (1, 3) und eine gemeinsame Saugleitung (7, 8) mit der Kältemittel(gemisch)versorgungseinrichtung verbunden.According to the invention, the evaporators (V, V ', V ", V"') have a common one Liquid line (1, 3) and a common suction line (7, 8) with the Refrigerant (mixture) supply device connected.

In der gemeinsamen Flüssigkeitsleitung (1, 3) ist ein Expansionsorgan, vorzugsweise ein Expansionsventil (4) angeordnet. Ferner kann die gemeinsame Flüssigkeitsleitung (1, 3) in den Verdampfern (V, V', V", V"') zugeordnete Venturi-Verteiler münden.

Figure 00000001
An expansion element, preferably an expansion valve (4), is arranged in the common liquid line (1, 3). Furthermore, the common liquid line (1, 3) in the evaporators (V, V ', V ", V"') associated with Venturi distributors can open.
