Definitions
- Valve device in particular for a refrigerating machine
- the invention relates to a valve device for a refrigerant circulating
- Refrigeration machine which is provided with at least one condenser and at least one evaporator.
- the valve device comprises at least one inlet, at which the refrigerant located in the condenser can be fed to the valve device and at least three outlets, by means of which the refrigerant present in the valve device can be diverted into the evaporator.
- the valve device further comprises a valve element, which is arranged rotatably about an axis and in a plurality of positions can be brought.
- the first outlet is connected to the inlet in a first position for passage of refrigerant.
- the second outlet is in a second position for passage of
- Refrigerant connected to the inlet.
- the third outlet is connected to the inlet in a third position for the passage of refrigerant. None of the at least three outlets is connected to the inlet in a fourth position.
- the invention has for its object to provide a valve device, which allows over the valve devices known from the prior art, a more efficient distribution of refrigerant in a refrigerator.
- valve device according to claim 1 is proposed.
- Advantageous embodiments of the valve device according to the invention are described in claims 2 to 8.
- the chiller is in particular part of a refrigeration device. Under a
- Refrigeration appliance is understood in particular a household refrigeration appliance, ie a refrigeration device that is used to housekeeping in households or possibly in the catering sector, and in particular serves to store food and / or drinks in household quantities at certain temperatures, such as a refrigerator, a freezer, a fridge freezer, a freezer or a wine storage cabinet.
- a household refrigeration appliance ie a refrigeration device that is used to housekeeping in households or possibly in the catering sector, and in particular serves to store food and / or drinks in household quantities at certain temperatures, such as a refrigerator, a freezer, a fridge freezer, a freezer or a wine storage cabinet.
- the valve device according to the invention is characterized in particular by the fact that the refrigerant circulated in the chiller can be distributed individually depending on the requirements. By opening two outlets at the same time, instead of setting three different options for adjusting the flow of refrigerant between condenser and evaporator of the chiller, six different settings are possible when the valve device is provided with three outlets. Furthermore, depending on the amount of refrigerant present in the condenser, the amount of refrigerant to be discharged can be varied. This is particularly advantageous when extremely high temperatures, for example above 70 ° C prevail in the condenser. Flow is in this context synonymous with flow.
- the at least three outlets are arranged equidistant from the axis. This configuration makes it possible for the different outlets to be released or blocked by means of the same regions of the valve element.
- the at least three outlets are located on a circle with the center of the circle on the axis, and the outlets in
- Circumferential direction of the circle are arranged equidistantly.
- This embodiment has the advantage that the positions of the valve element with respect to each of the three outlets can be transferred to other outlets.
- the three outlets are arranged coplanar.
- the three outlets are arranged in a plane that is orthogonal to the axis.
- the valve element comprises a setting wheel which is preferably rotatable about the axis A by means of a gear driven by a stepping motor.
- a Stepping motor is described, for example, in EP 1 176 346 B1.
- the valve device preferably has a stop, which prevents the valve element from being able to rotate over its entire circumference.
- the thumbwheel comprises a plate which is relative to the axis
- Rotational asymmetry here is synonymous with non-rotationally symmetric. This configuration allows the valve member to be operated over a radian measure of approximately 360 ° without causing any positions offset by 180 ° to have the same configuration of connections between the inlet and one or more outlets.
- the plate comprises at least two recesses, which connects the inlet with at least one of the at least three outlets for the passage of refrigerant.
- valve device is characterized by a sixth position and a seventh position, in which in each case at least two of the at least three outlets are connected to the inlet.
- at least one position is arranged, in which none of the at least three outlets is connected to the inlet.
- the refrigerant discharge from the condenser can be interrupted quickly.
- the refrigerating machine according to the invention comprises a valve device according to the invention.
- the refrigerating machine comprises a condenser, an evaporator, a compressor and at least three throttle devices arranged in parallel, which are each connected to one of the at least three outlets of the valve device and in each case to the evaporator.
- This configuration makes it possible to regulate the volume flow of the refrigerant passed from the condenser into the evaporator, by a single one of the at least three Throttle devices or at the same time two of the at least three throttle devices are used for the discharge of refrigerant.
- the chiller may include a condenser, at least three in parallel
- Valve device and each one of the at least three evaporators are connected comprise.
- the evaporators are each assigned to different temperature zones of the chiller, so that by means of the valve device also several temperature zones simultaneously through the supply of refrigerant to the respective
- Evaporators can be cooled down.
- the supply of refrigerant to an evaporator does not require that the refrigerant supply must be omitted in both at least remaining evaporators.
- the three throttle devices have different
- the pressure loss coefficient which can also be referred to as drag coefficient or flow resistance coefficient, is a dimensionless measure of the flow resistance of a body through which a fluid flows. Does the chiller while arranged in parallel evaporator in a consistent number with the number of outlets of the valve device, so can
- Pressure loss coefficients are selected so that the evaporators are optimally supplied with refrigerant. If a common evaporator is supplied with refrigerant by the throttle devices, then it is particularly advantageous to select the pressure loss coefficients of the respective throttle devices such that the volume flow
- volume flow of refrigerant of two parallel throttle devices corresponds. Because in this way, for example, the three throttle devices and the three positions at which two throttling devices are also opened in parallel, bring about a total of six different volume flows, otherwise a maximum of five.
- Valve device comprises the following method steps: Passing refrigerant from the inlet to the first outlet in a first position;
