Definitions

  • the present invention relates to a refrigerator, in particular a household refrigerator, for energy-efficient operation.
  • Silencers which serve to suppress flow noise at the suction port of the compressor, cause a pressure drop that affects the efficiency of the compressor. If you want to reduce this pressure drop, you usually have to accept a lower sound damping effect.
  • An important factor affecting the energy efficiency of a refrigeration appliance is the interruption of operation of the compressor and, if present, the fan, which are required because the cooling capacity of the compressor during operation is higher than the actual refrigeration capacity of the refrigeration appliance. If there is a pressure equalization between different areas of the refrigerant circuit in a standstill phase of the compressor, then the pressure in the evaporator increases. This leads to an increase in the boiling point of the refrigerant therein, so that the cooling effect that would be achievable without this increase in pressure with the present when switching off the compressor in the evaporator liquid coolant is not or only partially realized. Also connected to the pressure equalization between condenser and evaporator flow of warm refrigerant to the evaporator affects its cooling effect.
  • a refrigeration appliance in particular a household refrigeration appliance, having at least one assembly operable at different non-zero or non-standstill values of the operating parameter influencing the noise emission and a control unit which is set up in a first operating mode Operational parameters to vary autonomously, the control unit is switchable to a second mode, in which the control unit the Module with a single non-zero value of the operating parameter.
  • This value will generally be that among the various first variable settable non-zero values of the operating parameter which minimizes the noise emission of the device, or it will be selected at least among a plurality of respective relatively low values of noise emission corresponding parameter values.
  • a value of the operating parameter is chosen which gives a slightly higher than the optimum operating noise level, but also a higher cooling performance than a lower ambient temperature selected value, it can be ensured that suitable storage conditions can be maintained even in the second operating mode ,
  • controlled assemblies are in particular a compressor or a fan into consideration; an application to other noise generating assemblies, if any, is obviously also possible.
  • the operating parameter may in particular be a rotational speed or, in the case of a non-rotating drive, a frequency of a drive of the module.
  • the control unit is preferably set up to select the value of the operating parameter as a function of the ambient temperature in the first operating mode, and in particular to adapt it to changing ambient temperatures as long as the first operating mode is stopped.
  • the operating parameters are set only once based on the temperature detected during the transition to the second operating mode.
  • the control can be kept simple in the second operating mode; The limited duration of the second operating mode nevertheless entails that the value of the operating parameter is updated from time to time and adapted to the ambient temperature.
  • a user interface may be provided to control the switching of the control unit between the modes of operation according to a user's wishes.
  • the control unit can also have a time switching unit for switching over the operating modes in a time-controlled manner.
  • the times at which this timer unit switches can be fixed, e.g. programmed by the manufacturer.
  • the timer unit is combined with the user interface to allow the user to set the switching times.
  • a user can program times of day when he stays within earshot of the refrigerator as times of operation in the second operating mode.
  • control unit is provided with memory space to store at least one daily or weekly recurring pattern of switching times and thus spare a user a frequent re-entry of the switching times.
  • This memory location should preferably be of a type that also holds data stored in the event of a power failure, such as an EEPROM or a flash memory.
  • the user interface should also have a switching element for instant switching at least from the first to the second operating mode to allow the user to reduce the operating noise substantially immediately at any time when it is distracting, with immediate effect.
  • the second mode of operation will generally not be suitable for indeterminate operation, since the quietest mode of operation that meets this requirement will be determined by the manufacturer of the refrigerator as the first mode of operation. So that a user can not extend the second operating mode indefinitely by repeated actuation of the switching element, it can be provided that after one Return from the second to the first operating mode, a switch back to the second operating mode is temporarily disabled.
  • the same switching element or another switching element can serve to switch back to the first operating mode.
  • control unit is set up to switch back to the first operating mode at the latest after a predetermined maximum operating time has expired in the second operating mode. In this way, it is ensured that the refrigeration device operates at energy-saving times, at which the noise emission associated with the energy-saving operation does not disturb a user.
  • Other criteria for switching back to the first mode of operation may be:
  • the opening and / or closing a door of the refrigerator When the door has been opened, there is a high probability that fresh, warm refrigerated goods have been stored and that the cooling capacity available in the second operating mode is not sufficient to cool this refrigerated goods within a reasonable time. Moreover, the access to the door suggests that at least one user is awake in the environment of the refrigerator, so his sleep does not need to be protected by a low noise level of the refrigerator.
  • control unit can be set up to switch over to a value of the operating parameter that corresponds to a higher cooling capacity if the temperature in the storage area exceeds a permissible maximum.
  • the maximum allowable temperature for the particular storage area may be adjustable by a user. Thus, the user may consider to what extent he is willing to accept temporary warming of the storage area for quiet operation.
  • Assemblies whose operation requires cooling power such as an icemaker and / or a cold water dispenser should be expediently released for operation only in the first operating mode, but blocked in the second operating mode.
