Definitions

  • the invention relates to a method for operating a refrigerator and / or freezer.
  • the invention further relates to a refrigerator and / or freezer.
  • Refrigeration units for refrigerators and / or freezers such as speed-controlled compressors, which can be operated with different capacities as required. Very good energy efficiency can be achieved at a moderate power level. At the same time, by increasing the capacity, there is the possibility of calling up a higher cooling capacity with a somewhat lower efficiency.
  • the object of the present invention is to improve the energy efficiency of a refrigerator and / or freezer.
  • a method for operating a refrigerator and / or freezer with at least one refrigeration unit is provided, the refrigeration unit being selectively operable or operated at one of at least two different power levels.
  • the method is characterized in that the duration of a running time and / or a standing time of the refrigeration unit is changed depending on a characteristic of the energy with which the refrigeration unit is operated.
  • the choice between different power levels of the refrigeration unit can be used when connecting the refrigerator and / or freezer to an intelligent power grid for the most efficient operation of the refrigerator and / or freezer, which can, for example, achieve cost savings or other optimizations.
  • Smart Grid Mode The operation of a refrigerator and / or freezer using a method according to the invention is also referred to hereinafter as "Smart Grid Mode".
  • switch-on condition or “switch-off condition” used in the following stand for threshold values of a device-specific measured variable, such as, for example, the temperature of the cooled interior or the evaporator temperature. If the switch-on condition is met, the refrigeration unit can be switched on or an operating cycle or an operating mode of the refrigeration unit can be started. If the switch-off condition is met, the refrigeration unit can switched off or an operating cycle or an operating mode of the refrigeration unit are ended.
  • operating cycle used in the following stands for the operation of the refrigeration unit between the existence of a switch-on condition and the subsequent achievement of a switch-off condition. It can correspond to the total running time of the compressor or the running time of the compressor between two standing times.
  • the cooling unit is operated with an input power stage when a switch-on condition is present. If necessary, the refrigeration unit will be activated after the switch-on condition after its idle time.
  • the refrigeration unit is operated with a subsequent power level within a time interval if a switch-off condition is not reached.
  • the transition to a subsequent power level takes place within an operating cycle of the refrigeration unit and may be due to the fact that the switch-off condition is not reached or is reached prematurely within the time interval.
  • the subsequent performance level can be higher or lower, i.e. correspond to a higher or lower cooling capacity.
  • the refrigeration unit can optionally be operated on one of at least three, four or n different power levels, where n is an integer 2 2.
  • n is an integer 2 2.

Suitable characteristics include the (current) electricity tariff or price, the (current) network utilization, the CO 2 balance of the electricity supplied, the environmental balance of the electricity supplied, the availability of locally stored electricity, the filling level of storage facilities, the Power source, whether it is electricity generated in your own household, and the like.
  • the duration of a running time until the cooling unit is switched from one power level to a higher or lower power level is changed, preferably lengthened or shortened, depending on the characteristic of the energy.
  • the duration of a running time until the cooling unit is switched off is changed, preferably lengthened or shortened, depending on the characteristic of the energy.
  • the duration of a standing time until the cooling unit is switched on is changed, preferably lengthened or shortened, depending on the characteristic of the energy.
  • the duration of the runtime and / or standing time is extended or shortened by adding or subtracting a fixed or changeable time.
  • the shortening or extension of the running time and standing time is preferably between approximately -60 minutes and approximately +720 minutes, and further preferably between approximately -40 minutes and approximately +240 minutes.
  • the added time or the allowed time window for an extension and / or shortening of the running time and / or standing time can be different for each switch from one power level to a higher or lower power level or depending on the current power and may be specified in the parameter set of the device.
  • a status bit is set depending on the energy signal.
  • the duration of a running time and / or a standing time of the cooling unit can be changed depending on the status bit.
  • a status bit has the value 0 or 1, for example.
  • the status bit can be set to 0 or 1 in response to a low or high electricity tariff.
  • the performance can be kept low for a disadvantageous characteristic, such as, for example, a high electricity tariff, or reduced prematurely.
  • a disadvantageous characteristic such as, for example, a high electricity tariff
  • the performance can be kept high for a longer time or increased prematurely.
  • a power level has a better efficiency and a lower absolute cooling power compared to a higher power level.
  • a higher power level can have both a higher cooling capacity and a higher power consumption. When the output increases, the power consumption can increase more than the cooling output or disproportionately to the cooling output.
  • the efficiency is defined as the cooling capacity achieved per required energy unit.
  • the benefits derived from a good characteristic for example the cost savings, at least compensate for and preferably overcompensate for the additional consumption of the device per refrigeration unit produced with a higher output of the refrigeration unit.
  • the performance of the refrigeration unit can be changed continuously.
  • the duration of a running time until the cooling unit is switched from one power level to a higher or lower power level can correspond in this embodiment to a delay in the increase or decrease in power at a specific power threshold or to staying in a specific power range.
  • the change in the duration of a term and / or a standing time of the refrigeration unit can correspond to the introduction or deletion or lengthening or shortening of such a delay or dwell time.
  • the performance of the refrigeration unit can be changed in stages.
  • the dependence of the duration of the running time and / or the standing time on the characteristic of the energy can be activated and / or deactivated.
  • the connection or disconnection can take place automatically and / or manually, and during or outside an operating cycle.
  • the refrigerator and / or freezer should always be able to provide the cooling capacity required by the user by entering commands or by his behavior.
  • a device-specific measured value such as the inside temperature of a refrigerator or freezer and / or a calculated value determined from the measured value or values deviates from a specified value such as a temperature selected by the customer or lies outside a tolerance range
  • the smart grid mode is preferably automatically deactivated and a conventional power control of the device can be used. If the deviation no longer exists, the smart grid mode can preferably be reactivated automatically.
  • the smart grid mode can be deactivated automatically, for example, when the device electronics recognize that the cooling specifications cannot be achieved by operating in the smart grid mode.
  • the implementation of an early detection for the deviation from a preset value and the early change to the power control without smart grid mode can also be provided in a method according to the invention.
  • a limit power level that does not correspond to the highest or lowest possible power level of the refrigeration unit can be specified for the operation of the refrigeration unit.
  • an upper limit power level for example, a high noise level and / or a poor efficiency of the device can be avoided.
  • a limit power level can be set so that when the cooling unit is operating below this limit, the efficiency of the cooling unit is sufficient and cooling capacities above this limit value are associated with a lower efficiency. If necessary, this limitation is only applied if there is no refrigeration-related reason, such as insufficient cooling despite operation over a time interval at the limit power level.
  • the switch from the second highest to the highest power level can be delayed.
  • the increase and / or decrease in output can be delayed as soon as the output reaches a certain threshold.
  • Suitable threshold values include, for example, approximately 20% of the maximum power as the lower limit power level and approximately 70% of the maximum power as the upper limit power level.
  • a switch-on condition and / or a switch-off condition can also be changed as a function of the characteristic of the energy, in particular reduced and / or increased by adding offset values.
  • This offers an additional possibility of dynamically controlling the power consumption.
  • the switch-on temperature can be reduced at a low electricity tariff, so that the compressor can be switched on again quickly.
  • a change in a switch-on condition and / or switch-off condition can be reversed if, in order to achieve this changed switch-on condition and / or switch-off condition, the refrigeration unit is to be operated beyond a limit power level.
