Definitions
- the invention relates to a refrigeration system with at least one cooling circuit, which at least one condenser, at least one refrigeration consumer and at least has a compressor, the refrigerant via at least one riser is supplied to the condenser.
- Refrigeration systems of the generic type are used, for example, in supermarkets operated. They generally supply a large number of cold consumers, such as such as cold rooms, refrigerators and freezers. For this purpose a one or circulates in them multi-component refrigerant or refrigerant mixture.
- Such a refrigeration system As is known for example from DE-PS 39 28 430 - has one Condenser in which the pressurized refrigerant through indirect heat exchange, is preferably condensed against outside air.
- the liquid refrigerant from the condenser is fed to a collection container.
- a collection container There must always be as much refrigerant in a refrigeration system as it does at maximum cooling demand, the evaporators of all cooling consumers are filled can. However, since individual evaporators are only partially used when cooling is low are filled or even completely empty, the excess refrigerant must during these times are collected in the designated container.
- the refrigerant is fed to the refrigeration consumers from the collection container.
- Each The cooling consumer is an expansion device, preferably an expansion valve upstream or assigned, in which the refrigeration consumer or the refrigerant flowing through the evaporator of the refrigeration consumer is expanded.
- the refrigerant so relaxed becomes in the evaporators of the refrigerant consumers evaporates and cools the corresponding refrigeration furniture and rooms.
- the refrigerant evaporated in this way is then passed through a suction line Compressor unit supplied These compressor units can have one or more stages be trained.
- the individual compressor stages usually have several in parallel switched compressor. These compress and convey the refrigerant a riser in turn to the previously mentioned condenser.
- the object of the present invention is to provide a refrigeration system of the generic type specify, in which the disadvantages mentioned are avoided.
- a refrigeration system which is thereby is characterized in that the riser has a substantially horizontal, one Has sink area, and out of this a line that into one of the condenser area leading away from the condenser branches.
- At least one of the risers 1 has a region 2 which runs essentially horizontally and has a depression on, from which a line 4 which leads away from the condenser Line area 3 opens, branches.
- the refrigeration system according to the invention is proposed that the line 4 at least one shut-off device, preferably a valve, and / or at least one Flow meter has.
- the line 4 is used only for oil compensation, its line diameter can be smaller than the pipe diameter of the riser 1.
- the refrigeration system according to the invention enables safe operation even in part-load operation Supply of relevant system parts with oil.
- the provision of several, arranged in parallel There is no need for riser pipes between the compressor or compressors and the condenser itself, which results in lower investment costs for such a system.
