Definitions

  • the present invention relates to a refrigerator and / or freezer with at least one refrigerated compartment and at least one refrigerant circuit having at least one compressor and at least one evaporator for cooling said compartment and at least one arranged upstream of the evaporator capillary.
  • Cooling and / or freezing appliances known from the prior art usually have a refrigerant circuit which has a compressor, a condenser, a capillary as a throttle element and an evaporator.
  • the compressor the refrigerant is compressed, the compressed refrigerant is supplied to the condenser and passes under the release of heat from the gaseous to the liquid state.
  • the liquefied refrigerant in this way then enters the capillary, where it experiences a pressure drop.
  • the refrigerant flows into the evaporator, in which it passes from the liquid to the gaseous state and thereby absorbs heat from the compartment to be cooled.
  • the gaseous refrigerant then passes again via a suction line to the compressor, so that a total of a closed refrigerant circuit is present.
  • At least one temperature sensor is provided which determines the actual value of the temperature. This is compared with a setpoint.
  • the compressor is turned on and off in response to this comparison, causing the temperature in the refrigerated compartment to fluctuate around a set point.
  • the compressor is designed such that it always provides a sufficient cooling capacity or a sufficient flow rate of refrigerant in the storage of goods. If such a compressor is operated in continuous operation for the purpose of keeping the temperature constant, this has the disadvantage that a very low temperature is set in continuous operation. Because in order to provide a sufficient cooling capacity at a storage of goods, the performance of the compressor is usually much higher than is necessary to maintain the temperature typically set.
  • the present invention is based on the object to provide a refrigerator and / or freezer of the type mentioned, in which with low energy consumption, a constant or substantially constant temperature in the refrigerated space, in particular in a freezer can be achieved.
  • the refrigerant circuit has at least one arranged upstream of the capillary valve, which is in communication with the capillary, that the capillary depending on the valve position It is flowed through with refrigerant, and that at least one control or regulating unit is provided, which communicates with the valve and which is designed such that it adjusts the valve position in dependence on the cooling demand prevailing in the compartment.
  • the refrigeration capacity can be regulated by a cyclic activation of the solenoid valve, while the compressor is constantly in operation.
  • refrigerant may flow through the at least one capillary, while the refrigerant in the other position may not flow through the at least one capillary.
  • the compressor can continue to operate without the internal temperature dropping too far.
  • the reduced power consumption also reduces the flow rate of the compressor.
  • the refrigerant circuit has exactly one capillary, and that the valve is arranged directly or indirectly upstream of this capillary.
  • the refrigerant circuit has at least two capillaries arranged upstream of the evaporator in the flow direction of the refrigerant, which are designed such that at least two of the capillaries have different flow rates, wherein the valve is in flow connection with the capillaries in such a way that depending on the valve position or a second or both or more or all of the capillaries are flowed through with refrigerant.
  • a flow rate is the amount of refrigerant per unit time that flows through the capillary at a certain pressure difference before and after the capillary.
  • a capillary with a low flow rate is produced for the same inlet-side pressure or for the same pressure difference over the length of the capillary Capillary with less refrigerant per unit time flows through than a relatively larger flow rate capillary.
  • said valve can be adjusted to release the high flow rate capillary, i. the refrigerant passes to the evaporator through the high flow rate capillary.
  • said valve can be adjusted to release the low flow rate capillary through the valve, i. the refrigerant passes to the evaporator through the low flow rate capillary.
  • valve is switched so that both or more capillaries simultaneously be released, so that the refrigerant flows simultaneously through several capillaries to the evaporator.
  • valve is able to shut off all capillaries.
  • the device in particular a freezer or a freezer compartment, has at least one refrigerant circuit which has at least one valve which makes it possible to choose between at least two capillaries with different flow rates. Due to the different flow rates, at least two or, in the case of more than two capillaries, also more different cooling capacities are available.
  • valve is a multi-way valve.
  • the valve may, for example, be electrically operated or be operated manually.
  • the different flow rates of the at least two capillaries can be produced, for example, by carrying out the capillaries with different inner diameters.
  • the smaller the inner diameter the greater the pressure loss that arises when flowing through the capillary and the lower the flow rate of the capillary.
  • a capillary of small length over the length of the capillary has a lower pressure loss and thus a higher flow rate than a longer capillary.
  • At least one fan preferably at least one fan variable in its speed is arranged.
  • at least one fan by means of which the cooled air in the compartment is circulated or promoted, can also influence the temperature in the compartment influence.
  • the term "in the compartment” includes not only the case where the fan is located directly in the compartment, but also the case where the fan is in an evaporator module, which in turn is in the refrigerated compartment.
  • the fan is preferably designed such that the evaporator of the refrigerant circuit, by means of which the compartment is cooled, is arranged on the pressure side or suction side relative to the fan. This means that during operation the fan actively moves the air cooled by the evaporator away from the evaporator or supplies the air heated to the compartment to the evaporator.
