Definitions
- the invention relates to a product display cabinet with at least two evaporators and liquid and suction lines through which the evaporators enter Refrigerant (mixture) that comes from a refrigerant (mixture) supply device originates, is supplied or is removed from these.
- the object of the present invention is a generic Specify goods display furniture, in which a cost saving by Reduction of components can be achieved and moreover a faster and simplified assembly of the furniture, especially in the shop, is possible. Furthermore, a safe and better tightness of the Refrigerant (mixed) circuit can be guaranteed.
- a product presentation furniture is proposed that is characterized in that the evaporator has a common Liquid line and a common suction line with the Refrigerant (mixture) supply device are connected.
- the evaporators of a product display unit are now refrigeration interconnected to an evaporator.
- the inventive Merchandise display furniture is just an expansion organ, where it is is preferably an expansion valve required.
- FIG. 9 The figure shows two evaporators V and V ', the cooling of a cooling air stream 9th or 10 serve.
- any number of furniture items can be displayed Evaporator - represented by the dashed line evaporators V "and V" '- provided become.
- a refrigerant or refrigerant mixture is supplied to a liquid line 1 supplied inner heat exchanger 2 and in this by the gaseous Refrigerant (mixture) in line 7, which will be discussed in more detail below will be hypothermic. Then the refrigerant (mixture) via line 3 fed to an expansion valve 4 and relaxed in this. The resulting Liquid / gas mixture is now evenly on lines 5 and 5 ' the evaporators V and V 'distributed. This can be done, for example, by means of so-called venturi distributors respectively.
- suction line is such that a heat exchange can be realized not mandatory.
