  • the condensed refrigerant in the condenser 13 is re-distributed toward the first evaporator 14 and the second evaporator 15 by means of the refrigerant switching valve 16 for circulation. Such series of processes are repeated.
  • the refrigerant switching valve 16 blocks the direction toward the second evaporator 15 as the refrigerating chamber refrigeration cycle, and opens only the direction toward the first evaporator 14 as the freezing chamber refrigeration cycle, such that a refrigerant flowed through the condenser 13 can move only toward the first evaporator 14.
  • the primary compressor 11 and the secondary compressor 12 are driven simultaneously. Accordingly, the refrigerant flowed through the first evaporator 14 can circulate with being secondarily compressed sequentially via the primary and secondary compressors 11 and 12.
  • the refrigerant switching valve 16 blocks the direction toward the first evaporator 14 as the freezing chamber refrigeration cycle and opens the direction toward the second evaporator 15 as the refrigerating chamber refrigeration cycle. Also, only the secondary compressor 12 starts to be driven with the primary compressor 11 stopped.
  • a refrigerant flowed through the condenser 13 flows only toward the second evaporator 15 to be introduced into the secondary compressor 12.
  • the refrigerant which is discharged after being compressed in the secondary compressor 12, flows into the condenser 13 to be condensed. Such series of processes are repeated.
  • the refrigerator can be driven with the refrigeration cycles, which are independently run in correspondence with the load of the freezing chamber or the refrigerating chamber, which allows reduction of unnecessary power consumption of the refrigerator, thereby remarkably improving efficiency of the refrigerator.
  • a refrigerant may be biased to any one side according to loads of the freezing chamber and the refrigerating chamber when the refrigerator is driven in the simultaneous driving mode or the freezing chamber driving mode.
  • the temperature of the refrigerator may not reach a target temperature, accordingly, an operating factor is increased to make the refrigerator consecutively driven, which may further increase power consumption.
  • FIGS. 3 to 8 are block diagrams each showing a micom, which is capable of preventing a refrigerant from being biased toward one evaporator in the refrigerator, and flowcharts showing a driving method for the refrigerator using the micom.
  • vibration sensors 21 may be installed at the primary compressor 11 and the secondary compressor 12, respectively.
  • a micom 30 may be electrically connected to the vibration sensors 21 so as to vary a cooling capability of one of the compressors according to the number of vibration of each of the primary and secondary compressors 11 and 12, detected by the vibration sensors 21.

  • the vibration sensor 21 provided at the primary compressor 11 may detect the number of vibration of the primary compressor 11 so as to input to the input part 31 of the micom 30.
  • the determination part 32 may then compare the detected number of vibration with a reference number of vibration (i.e. reference value) to determine whether the flow of the refrigerant is biased toward the first evaporator 14 (namely, whether or not a uniform distribution of the refrigerant is needed).
  • a reference number of vibration i.e. reference value
  • the cooling capability of the primary compressor 11 may be increased so as to mostly circulate the refrigerant biased toward the first evaporator 14. Accordingly, the amount of refrigerant discharged out of the first evaporator 14 may be increased while the amount of refrigerant discharged out of the second evaporator 15 may be relatively decreased. Hence, the refrigerants at both the evaporators 14, 15 may be added and reduced with each other to be balanced.
  • the vibration sensor 21 provided at the secondary compressor 12 may be used to determine whether or not the flow of the refrigerant is biased toward the second evaporator 15. If it is determined the flow of refrigerant is biased toward the second evaporator 15, the cooling capability of the second evaporator 15 may be increased to mostly circulate the refrigerant biased toward the second evaporator 15. Accordingly, the amount of refrigerant discharged out of the second evaporator 15 may be increased while the amount of refrigerant discharged out of the first evaporator 14 may be relatively decreased. Hence, the refrigerants at both the evaporators 14, 15 may be added and reduced with each other so as to be balanced.
  • the driving method for the refrigerator shown in FIGS. 5 and 6 may be configured to balance the amount of refrigerant by adjusting an open value of a refrigerant switching valve. That is, temperature sensors 22 may be installed at the first and second evaporators 14 and 15, respectively, to detect an evaporation temperature of the first evaporator 14 (i.e., a temperature difference between the inlet and the outlet of the first evaporator) and an evaporation temperature of the second evaporator (i.e., a temperature difference between the inlet and the outlet of the second evaporator).
  • the refrigerant switching valve 16 and the temperature sensors 22 may be electrically connected to the micom 30, respectively, to control an open value of the refrigerant switching valve 16 according to each evaporation temperature detected by the temperature sensors 22.
  • the temperature sensors 22 may be installed at both inlet and outlet of the first evaporator 14 to detect a temperature difference therebetween, and also at both inlet and outlet of the second evaporator 15 to detect a temperature difference therebetween.
  • the micom 30 may include an input part 31 electrically connected to the temperature sensors 22 to receive the respective evaporation temperatures of the first and second evaporators 14 and 15, a determination part 32 connected to the input part 31 to compare the received evaporation temperature of each evaporator 14, 15 with a reference temperature to determine to which evaporator the flow of the refrigerant is biased, and an instruction part 33 connected to the determination part 32 to instruct an opening or closing of the refrigerant switching valve 16.
  • the temperature sensors 22 located at the inlet and outlet of the first evaporator 14 detect the evaporation temperatures (i.e., temperature difference) of the first evaporator 14 and input the detected evaporation temperatures to the input part 31 of the micom 30.
  • the determination part 32 compares the evaporation temperatures of the first evaporator 14 with a reference temperature to determine whether the flow of the refrigerant is biased toward the first evaporator 14 (i.e., whether a uniform distribution of refrigerant (refrigerant balancing) is needed).
  • the refrigerant switching valve 16 is kept open in the direction toward the refrigerating chamber, namely, toward the second evaporator 15, and varies an open level in the direction toward the freezing chamber, namely, toward the first evaporator 14 so as to control the amount of refrigerant flowing toward the first evaporator 14, thereby balancing the flow of refrigerant (the amount of refrigerant).
  • the refrigerant switching valve 16 is kept open toward the first evaporator 14, and varies the open level toward the second evaporator 15 so as to control the amount of refrigerant flowing toward the second evaporator 15, thereby balancing the flow of refrigerant (the amount of refrigerant).
  • the micom 30 may further include a timer 23 electrically connected to the refrigerant switching valve 16 to detect an open time of the refrigerant switching valve 16.
  • the micom 30 may include an input part 31 electrically connected to the timer 23 to receive the detected open time of the refrigerant switching valve 16, a determination part 32 connected to the input part 31 to compare the received open time of the refrigerant switching valve 16 with a reference open time (reference value) so as to determine or predict to which evaporator the flow of refrigerant is biased (more refrigerant flows), and an instruction part 33 connected to the determination part 32 to instruct the controlling of the open time of the refrigerant switching valve 16.
  • the balancing of the amount or flow of refrigerant can be achieved by detecting the open time of the refrigerant switching valve 16, comparing the detected open time with the reference value to determine or predict the biasing of the flow of the refrigerant, and controlling the open time of the refrigerant switching valve 16 such that less refrigerant is introduced into the passage toward the side determined as the flow of refrigerant is biased.
  • the determination of the open time of the refrigerant switching valve 16 may be performed in the order of determining whether the open time in the direction toward the first evaporator 14 exceeds a preset open time, and determining whether the open time in the direction toward the second evaporator 15 exceeds the preset open time when determined the open time in the direction toward the first evaporator 14 did not exceed the preset open time.
  • the uniform distribution (balancing) of refrigerant is similar to the second exemplary embodiment, so detailed description thereof will be omitted.
  • the use of the timer 23 allows the open time to be periodically adjusted after a predetermined time, accordingly, the control process can be more simplified.
  • the refrigerant can be uniformly distributed toward first and second evaporators by several methods, such as changing a cooling capability of a compressor according to a detected number of vibration of the compressor, detecting evaporation temperatures of each evaporator to vibration of the compressor, detecting evaporation temperatures of each evaporator to control a refrigerant switching valve for controlling the flowing direction of refrigerant, or detecting an open time of the refrigerant switching valve to control the open time of the refrigerant switching valve. Consequently, the refrigerator can be driven with refrigeration cycles, which are independently run in correspondence with the load of the freezing chamber or the refrigerating chamber, resulting in reduction of unnecessary power consumption of the refrigerator.
  • an open value or open time of the refrigerant switching valve can be adjusted by detecting the number of vibration of the compressor, and also the capability of the compressor can be controlled by detecting the evaporation temperatures of the evaporators or the open time of the refrigerant switching valve.
