  • the cooler comprising a heat controlled special compartment, realized to achieve the aim of the present invention and disclosed in the first claim and the dependent claims, comprises a control unit determining the times in which a fan is turned on and off at least when the compressor is halted or operated, by controlling the data received from a first heat sensor measuring the temperature in at least one cooler compartment and from a second heat sensor measuring the temperature in the special compartment.
  • the control unit determines whether the fan should be activated depending on the temperatures of at least the cooler compartment and the special compartment, and enables maintaining the temperature in the special compartment between determined temperature values and enables maintaining the homogeneity of the air temperature in the cooler compartment.
  • the control unit when the compressor is not running, i.e. is turned off, the control unit does not activate the fan until the temperature in the cooler compartment reaches an upper limit temperature determined by the producer and saved in the control unit, or until the temperature in the special compartment reaches a lower limit temperature determined by the producer and saved in the control unit, and activates the fan upon the cooler compartment temperature reaching said cooler compartment upper limit temperature, or upon the special compartment temperature reaching said special compartment lower limit temperature.
  • the fan is enabled to be not activated almost at a predefined ratio depending on conditions such as the temperature values measured by the sensors, compressor operation ratio, the ambient temperature, the door being opened, loading of new items, and the like.
  • the fan When the fan is not activated, the air pouring from the surface of an evaporator which is cold, enables the special compartment to be cooled for some more time, and the homogeneity of the air temperature in the cooler compartment is provided by activation of the fan later on.
  • the control unit when the compressor is initially activated after a halted period, the control unit activates the fan after a duration predetermined by the producer and saved in the control unit, following activation of the compressor.

  • control unit activates the fan, if, while the compressor is running, the special compartment temperature reaches a compressor halting special compartment temperature determined by the producer and saved in the control unit, before the cooler compartment temperature reaches a compressor halting cooler compartment temperature determined by the producer and saved in the control unit.
  • the special compartment is thus prevented from overcooling.

  • the control unit provided in the cooler of the invention does not activate the fan until the evaporator surface temperature reaches a limit temperature determined by the producer and saved in the control unit, and activates the fan if the evaporator surface temperature reaches said evaporator limit temperature.
  • the temperature in the special compartment is thus prevented from increasing by not running the fan to an extent when the compressor is not running.

  • the fan is prevented from blowing air of a temperature hotter than 0°C towards the special compartment, thereby maintaining the air in the special compartment at a desired temperature.
  • the air pouring from the surface of the evaporator when the fan is not activated enables the special compartment to stay cool for some more time, and the temperature swings in the cooler compartment due to delayed activation of the fan are eliminated by the activation of the fan, providing temperature homogeneity in the cooler compartment.
  • the control unit halts the fan and activates the heater after temperature homogeneity is provided in the cooler compartment.
