Definitions
- the present invention relates to a refrigeration device, in particular a household refrigeration device such as a refrigerator, a freezer or a fridge-freezer combination.
- a refrigeration circuit In refrigeration appliances, in particular in household refrigeration appliances such as refrigerators, freezers or fridge-freezers, a refrigeration circuit is provided which typically has a refrigerant compressor, a condenser, a throttle, an evaporator and a recirculation line.
- the throttle is usually designed as a capillary tube which connects an outlet of the condenser to an inlet of the evaporator.
- a valve is usually provided which is arranged between an inlet of the capillary tube and a connecting tube which is connected to the outlet of the condenser.
- DE 60 2004 010 153 T2 discloses a refrigeration device with a refrigeration circuit in which a capillary tube between the condenser and the evaporator is divided into two.
- a first capillary tube is connected to an outlet of a connecting tube connected to the condenser and to an inlet of a collection container
- a second capillary tube connects an outlet of the collection container to an inlet of the evaporator.
- a return line from the condenser to a compressor is in thermally conductive contact with the capillary tubes and the header tank. The aim of this design is to supercool the coolant in the area of the collection tank outlet in order to facilitate flow control.
- CN 108168131 A discloses a refrigerator with a combined throttling device which has a first capillary tube, an intermediate cooler and a second capillary tube, with a return line from an evaporator to a compressor via the intermediate cooler achieving heat exchange.
- This structure serves that Purpose to reduce noise due to refrigerant fluctuations when exiting the throttling device.
- DE 10 2015 221 441 A1 also discloses a refrigerator with two capillary tube groups arranged in series, the first capillary tube group being arranged between a first valve and a second valve. By switching the valves, different flow paths with different throttling effects can be realized in order to vary a flow rate.
- the capillary tubes are designed in such a way that a desired throttling effect of the refrigerant or a predetermined flow rate is achieved. This can result in the capillary tube having a great length if there are only low flow resistances upstream of the capillary tube, which is fundamentally desirable.
- this object is achieved by a refrigeration device having the features of claim 1 .
- a refrigeration device in particular a household refrigeration device such as a refrigerator, a freezer or a fridge-freezer combination.
- the refrigeration device comprises at least one refrigeration compartment for accommodating refrigerated goods and a refrigerant circuit with a condenser, an evaporator thermally coupled to the at least one refrigeration compartment for cooling the refrigeration compartment, which is connected to the condenser, a dryer arranged between the condenser and the evaporator, and a valve device , which is connected to the dryer by an intermediate capillary tube and to the evaporator by a throttling capillary tube.
- One idea on which the invention is based is to achieve a throttling effect, which is to be achieved between a condenser and an evaporator of the refrigeration appliance, by means of separate capillary tubes connected in series.
- a throttling effect which is to be achieved between a condenser and an evaporator of the refrigeration appliance, by means of separate capillary tubes connected in series.
- an intermediate capillary tube connecting a dryer arranged downstream of the condenser with a valve device, and a throttle capillary tube connecting the valve device with the evaporator.
- the dryer is designed to remove water from the refrigerant coming from the condenser.
- the arrangement of the intermediate capillary downstream of the dryer advantageously avoids throttling of the refrigerant before it passes through the dryer.
- An advantage of the design according to the invention with an intermediate capillary tube is that the throttling valve tube, which causes the remaining desired throttling effect up to the evaporator, can be shortened. As a result, the overall length of the capillary tube can be shortened, which leads to savings in material and therefore costs.
- the intermediate capillary tube can run completely within a machine room of the refrigeration appliance, in which, for example, a compressor and the valve device are arranged.
- the intermediate capillary tube can be connected directly to an outlet of the dryer.
- an outlet of the dryer can be connected to an evacuation tube, with the intermediate capillary tube opening out of the evacuation tube.
- the intermediate capillary tube can thus be connected directly to an outlet of the drier or can be connected to an intermediate piece connected to the outlet of the drier. Connecting the intermediate capillary directly to the dryer offers the advantage that a structurally simple structure is achieved. A high degree of functional integration is advantageously achieved by connecting the intermediate capillary and the evacuation tube.
- the intermediate capillary tube runs uninterruptedly between the outlet of the dryer and an inlet of the valve device or uninterruptedly between the evacuation tube and the inlet of the valve device.
- the intermediate capillary tube itself is therefore preferably no longer subdivided. This achieves continuous throttling of the refrigerant along the intermediate capillary, further reducing flow noise.
- the intermediate capillary tube has a length in a range between 0.3 m and 1.0 m. Further optionally, the intermediate capillary tube can have a length in a range between 0.6 m and 0.9 m.
- the intermediate capillary tube has an inner diameter in a range between 0.55 mm and 0.8 mm. In this range, a good throttling effect is achieved for typical flow rates, e.g. in a range between 150 l/h and 300 l/h.

Accordingly, the function of the check valve and directional control valve can advantageously be combined in a single component.

- the throttle capillary tube has a length in a range between 2.00 m and 3.25 m.
- the length of the throttle capillary tube can thus be significantly reduced by the intermediate capillary tube. the.
