Definitions

  • the present invention relates to a cooling device the refrigeration performance of which is improved by controlling the refrigerant circulation.
  • circulation of the refrigeration cycle fluid used through the units composed of the compressor, the condenser, the capillary tubes and the evaporator makes up the refrigeration cycle.
  • the refrigerant fluid is directed by means of valve to one of the compartments.
  • the refrigerant fluid is directed to the evaporator in the compartment where the thermal load has increased and the compartment is cooled by means of the evaporator and the thermal load built up in the compartment is discharged by means of the condenser to the outer environment.
  • the refrigerant fluid After leaving the evaporator in the respective compartment, the refrigerant fluid recirculates the entire refrigeration cycle so as to be cooled again and then directed to the other compartment.
  • the thermal loads occurring in the compartments differ depending on the design and use of the cooling device, in which case the refrigeration cycle cannot meet the thermal load occurring in the compartments efficiently.
  • the aim of the present invention is to realize a cooling device of which the refrigeration performance is improved by controlling the condenser capacity according to the temperature value measured inside the compartment.
  • 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 fresh food compartment; a freezing compartment; a compressor enabling the refrigeration cycle to be carried out; a condenser enabling the refrigerant fluid leaving the compressor as superheated steam to be condensed and to be changed to liquid phase; at least one fresh food compartment evaporator that enables the fresh food compartment to be cooled; at least one freezing compartment evaporator that enables the freezing compartment to be cooled; a first temperature sensor that measures the temperature inside the fresh food compartment; a second temperature sensor that measures the temperature inside the freezing compartment; a first valve located at the outlet of the condenser, and a control unit that enables the refrigerant fluid leaving the condenser to be directed through the first valve to the fresh food compartment evaporator and/or the freezing compartment evaporator by analyzing the data from the first temperature sensor and the second temperature sensor.
  • the condenser is preferably a mini-channel heat exchanger.
  • the cooling device (1) of the present invention comprises
  • control unit In an embodiment of the present invention, the control unit
  • control unit In another embodiment of the present invention, the control unit
  • the cooling device comprises a second valve at the outlet of the second condenser line.
  • the second valve is preferably a three-way solenoid valve.
  • the control unit enables the refrigerant fluid to be directed from the second valve to the fresh food compartment evaporator or the freezing compartment evaporator depending on the data received from the first temperature sensor and the second temperature sensor.
  • the control unit checks the temperatures of the fresh food department and the freezing department and if the temperature of the fresh food compartment is greater than the critical temperature of the fresh food compartment, the control unit enables the refrigerant fluid to be transmitted to the fresh food compartment evaporator and if the temperature of the freezing compartment is greater than the critical temperature of the freezing compartment, the control unit enables the refrigerant fluid to be transmitted to the freezing compartment evaporator.
  • control unit enables the compressor to be stopped if the temperature of the fresh food compartment is lower than the limit temperature of the fresh food temperature and if the temperature of the freezing compartment is lower than the limit temperature of the freezing compartment, so that transmission of the refrigerant fluid is terminated.
  • the control unit prevents unnecessary energy consumption by terminating the refrigeration cycle.
  • a cooling device wherein the refrigerant fluid is passed through only some part of the condenser and sent to the respective compartment when the refrigeration need in the compartments is low and thus the refrigeration need of the compartments is met faster.
  • the temperatures inside the fresh food compartment and the freezing compartment are detected to determine the refrigeration need and if the refrigeration need in the compartments is low, the refrigerant fluid is passed only through the first condenser line of the condenser and directed to the fresh food compartment evaporator or the freezing compartment evaporator and if the refrigeration need in the compartments is high, the refrigerant fluid is passed through both the first condenser line and the second condenser line of the condenser and directed to the fresh food compartment evaporator or the freezing compartment evaporator.
  • the cooling device (1) comprises a fresh food compartment (2) wherein foodstuffs are placed to be cooled; a freezing compartment (3) kept at lower temperatures than the fresh food compartment (2) and wherein the foodstuffs are placed to be frozen; a compressor (4) that provides the compression of the refrigerant fluid; a condenser (5) that enables the refrigerant fluid leaving the compressor (4) to be condensed and changed to liquid phase; at least one fresh food compartment evaporator (6) which provides the cooling of the fresh food compartment (2) by enabling heat transfer between the refrigerant fluid and the environment; at least one freezing compartment evaporator (7) which provides the cooling of the freezing compartment (3) by enabling heat transfer between the refrigerant fluid and the environment; a first temperature sensor (8) which measures the temperature of the fresh food compartment (2) for the control of the cooling process; a second temperature sensor (9) which measures the temperature of the freezing compartment (3) for the control of the freezing process; a first valve (10) at the outlet of the condenser (5), and a control unit (11) which evaluates
  • the cooling device (1) of the present invention is a thermometer
  • the control unit (11) evaluates the data received from the first temperature sensor (8) and the second temperature sensor (9) and determines the compartment where the thermal load has increased and enables the refrigerant fluid leaving the first condenser line (12) to pass through the first valve (10) so as to be directed to the determined compartment and to be directed to the fresh food compartment evaporator (6) and/or the freezing compartment evaporator (7).
  • the refrigerant fluid is passed through both the first condenser line (12) and the second condenser line (13) or through only the first condenser line (12) and transmitted to the fresh food compartment (2) and/or the freezing compartment (3).
  • control unit (11) controls the control unit (11)
  • control unit (11) In another embodiment of the present invention, the control unit (11)
  • the cooling device (1) comprises a second valve (14) at the outlet of the second condenser line (13).
  • the second valve (14) has one inlet connected to the second condenser line (13) and at least two outlets connected to the fresh food compartment evaporator (6) and the freezing compartment evaporator (7).
  • the control unit (11) enables the refrigerant fluid to be directed from the second valve (14) to the fresh food compartment evaporator (7) or the freezing compartment evaporator (7) according to the data received from the first temperature sensor (8) and the second temperature sensor (9). If the temperature (T FF ) of the fresh food compartment (2) is greater than the critical temperature (T FFcr ) of the fresh food compartment (2), the control unit (11) detects that the fresh food compartment (2) needs to be cooled and ensures the transmission of the refrigerant fluid from the second valve (14) to the fresh food compartment evaporator (6) so that the fresh food compartment (2) is cooled.
  • the control unit (11) detects that the freezing compartment (3) needs to be cooled and ensures the transmission of the refrigerant fluid from the second valve (14) to the freezing compartment evaporator (7) so that the freezing compartment (3) is cooled.

In this case, the control unit (11) decides that the fresh food compartment (2) and the freezing compartment (3) are not required to be cooled, thus terminates the delivery of the refrigerant fluid to the fresh food compartment evaporator (6) and the freezing compartment evaporator (7).
  • the refrigerant fluid is passed through only the first condenser line (12) of the condenser or through both of the first condenser line (12) and the second condenser line (13).
  • the capacity of the condenser (5) is enabled to be increased or decreased so as to meet the different thermal loads occurred.
