Definitions

  • the present invention relates to a cooling device comprising a variable speed compressor.
  • Conventional cooling devices generally comprise a fresh food compartment wherein the foodstuffs are placed to be cooled and a freezing compartment which is kept at temperatures lower than the fresh food compartment and wherein the foodstuffs are placed to be frozen.
  • a compressor is operated by a control unit when the inner volume of the fresh food compartment reaches a fresh food compartment inner volume high temperature value determined by the producer in order to keep the inner volume of the fresh food compartment at a temperature which prevents the spoiling of the foodstuffs, and thus the cooling cycle is started and the cooling cycle continues until the inner volume of the fresh food compartment reaches a fresh food compartment inner volume low temperature value determined by the producer.
  • the control unit deactivates the compressor and ends the cooling cycle.
  • variable speed compressors in the cooling devices with such compressors
  • the control unit determines the speed of the compressor required for the cooling cycle and operates the compressor at this speed during the cooling cycle.
  • the compressor is not operated at the highest speed.
  • the cooling cycle is performed at relatively low compressor speeds. Therefore, the duration of the cooling cycle gets longer, which may cause the risk of the foodstuffs in the fresh food compartment getting spoiled.
  • German Patent Document No. DE102013114374 discloses a method for controlling the speed of a variable speed compressor which is a component of a cooling system such as refrigerator, freezer, air conditioner, heat pump, etc.
  • the aim of the present invention is the realization of a cooling device wherein the fresh food compartment is quickly and efficiently cooled, thus the foodstuffs stored in the fresh food compartment are prevented from getting spoiled.
  • the cooling device realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a variable speed compressor and at least one control unit which is configured to determine, before the new cooling cycle, the speed at which the compressor must be operated at the beginning of the new cooling cycle depending on the time during which the compressor is operated at the highest speed in the last cooling cycle and/or depending on whether the compressor is operated at the highest speed at the end of the cooling cycle. Before starting a new cooling cycle it is determined whether the cooling device has needed high cooling capacity in the previous cooling cycle depending on the highest speed at which the compressor is operated in the previous cycle or depending on the duration during which the compressor is operated at the highest speed.
  • the new cooling cycle is started with the assumption that high cooling capacity will be needed. Consequently, the fresh food compartment is quickly and efficiently cooled, thus preventing the foodstuffs in the fresh food compartment from getting spoiled.
  • the cooling device comprises a control unit which stores the data related to a predetermined threshold time related to the time during which the compressor is operated at the highest speed in a cooling cycle and is configured to record the data related to the time during which the compressor is operated at the highest speed in a cooling cycle, to process the recorded data before starting a new cooling cycle in order to compare the threshold time value with the time during which the compressor is operated at the highest speed in the previous cooling cycle, and to activate the compressor at the highest speed in the new cooling cycle upon detecting, at the end of the comparison process, that the time during which the compressor is operated at the highest speed in the previous cooling cycle is equal to the threshold time value or higher than the threshold time value.
  • the compressor being operated at the highest speed for a time equal to a predetermined time or higher than this time value in the previous cooling cycle is interpreted as the need for high capacity for cooling the fresh food compartment, and therefore, it is assumed that the fresh food compartment will need high cooling capacity in the new cooling cycle. Therefore, the control unit activates the compressor so as to operate at the highest speed possible and starts the new cooling cycle which provides the efficient and quick cooling of the fresh food compartment.
  • control unit is configured to process the recorded data before starting a cooling cycle in order to compare the time during which the compressor is operated at the highest speed in the previous cooling cycle with the threshold time value, and then to, if it is detected that the time during which the compressor is operated at the highest value in the previous cooling cycle is lower than the threshold time value, process the actual fresh food compartment temperature data received from the temperature sensor in order to determine the speed required for operating the compressor and to operate the compressor at the determined speed at the beginning of the new cooling cycle.
  • energy saving is provided by preventing the compressor from being unnecessarily operated at the highest speed at the beginning of the cooling cycle.
  • control unit is configured to record the last speed value of the compressor before starting the defrost cycle for defrosting the freezing compartment, to compare the recorded compressor speed value at which the compressor is operated before the defrost cycle before starting the cooling cycle after the defrost cycle with the highest possible speed value for the compressor, and to operate the compressor at the highest speed in the new cooling cycle started after the completion of the defrost cycle if it is determined as a result of the comparison process that the compressor is operated at the highest speed before the defrost cycle.
  • the compressor which is operated at the highest speed before a defrost cycle and which is stopped for performing the defrost cycle is activated so as to be operated at the highest speed in the first cooling cycle performed after the defrost cycle, thereby realizing an efficient and quick cooling process in the fresh food compartment.
  • control unit is configured to compare the recorded compressor speed value at which the compressor is operated before the defrost cycle before starting the cooling cycle after the defrost cycle with the highest possible speed value for the compressor, and to, if it is determined as a result of the comparison process that the compressor is operated at a speed lower than the highest speed before the defrost cycle, process the actual fresh food compartment temperature data received from the temperature sensor in order to determine the speed required for operating the compressor and to operate the compressor at the determined speed in the cooling cycle to be performed after the defrost cycle.
  • energy saving is provided by preventing the compressor from being unnecessarily operated at the highest speed at the beginning of the cooling cycle to be performed after the defrost cycle.
  • the fresh food compartment inner volume is enabled to be efficiently and quickly cooled by operating the compressor at the highest speed in the new cooling cycle if the control unit determines that in the previous cooling cycle the compressor is operated at the highest speed for a predetermined time or longer than said predetermined time.
  • the fresh food compartment inner volume is enabled to be efficiently and quickly cooled by operating the compressor at the highest speed in the first cooling cycle after the defrost cycle if the control unit determines that the compressor is operated at the highest speed before the defrost cycle which is used for defrosting the freezing compartment.
  • Figure 1 - is the schematic view of the cooling device of the present invention.
  • the cooling device (1) comprises at least one fresh food compartment (2); a freezing compartment (3) which is disposed in the fresh food compartment (2) and which is kept at lower temperatures than the fresh food compartment (2); a compressor (4) which performs a cooling cycle by compressing and circulating a refrigerant fluid and which can be operated at variable speeds; at least one temperature sensor (5) which measures the temperature of the fresh food compartment (2), and at least one control unit (6) which is connected to the temperature sensor (5) so as to exchange data and which is configured to activate and deactivate the compressor (4) at least depending on the temperature values received from the temperature sensor (5) and to determine at least the speed required for operating the compressor (4) depending on the operational conditions, especially at least the actual temperature of the fresh food compartment (2) at the beginning of a cooling cycle and during the cooling cycle.
  • the foodstuffs to be cooled are placed into the fresh food compartment (2) while the foodstuffs such as meat, frozen food, etc. to be frozen to keep their freshness for a long time are placed into the freezing compartment (3).
  • the compressor (4) is operated by the control unit (6) at certain time intervals, which are also known as compressor duty cycle, at least depending on the temperature of the fresh food compartment (2) inner volume at a speed determined depending on the operational conditions such as the current temperature of the fresh food compartment (2) and suitable for cooling the inner volume of the fresh food compartment (2) at the desired level, and thus the compressor (4) compresses the refrigerant fluid and performs the cooling cycle.
  • the control unit (6) of the cooling device (1) of the present invention is configured to determine, before the new cooling cycle, the speed at which the compressor (4) must be operated at the beginning of the new cooling cycle at least depending on the time during which the compressor (4) is operated at the maximum speed in the last cooling cycle and/or depending on whether the compressor is operated at the maximum speed at the end of the cooling cycle.
