Definitions

  • the present invention relates to a cooling device comprising a fresh food compartment and a freezing compartment.
  • Domestic type cooling devices generally consist of two separate compartments, a fresh food compartment and a freezing compartment, that are kept at different temperatures.
  • the fresh food compartment is utilized preferably for storing fresh food and the freezing compartment for storing frozen food.
  • the refrigeration process is performed by means of evaporators disposed in the compartments, connected to each other in series or in parallel instead of forced air circulation.
  • both refrigeration circuits are connected to a single compressor.
  • the fresh food compartment temperature is taken as reference in some cooling devices and the freezing compartment is taken as reference in others.
  • the compressor cannot be used efficiently and energy consumption increases.
  • Operating conditions of the fan that is used in the cooling compartment and/or the freezing compartment and that provides the air in the compartment to be dispersed, are generally determined according to the operation of the compressor or the temperature values of the compartment wherein the fan is located. In embodiments wherein the fan is simultaneously operated with the compressor, the compartment temperature cannot be sensitively adjusted and energy is consumed unnecessarily. In situations wherein the operating conditions of the fan are determined according to the temperature values of the compartment in which the fan is located, the temperature of the related compartment may not reach the cut-in temperature of the fan according to the environment conditions and this prevents the homogeneous distribution of the cool air in the compartment.
  • JP10185395 a cooling device is described, wherein the fan disposed in the fresh food compartment is operated at certain temperature intervals in order to keep the fresh food compartment temperature constant when the freezing compartment temperature is used as the cut-in condition.
  • a cooling device that comprises a fresh food compartment fan, the operation of which is regulated according to the freezing compartment conditions.
  • the aim of the present invention is the realization of a cooling device, of which the cooling efficiency is improved.
  • the fresh food compartment temperature and/or the freezing compartment temperature should reach respectively the fresh food compartment temperature predetermined by the producer whereat the compressor is activated and/or the freezing compartment temperature predetermined by the producer whereat the compressor is activated.
  • the fresh food compartment temperature and the freezing compartment temperature should reach respectively the fresh food compartment temperature predetermined by the producer wherein the compressor is deactivated and the freezing compartment temperature predetermined by the producer wherein the compressor is deactivated.
  • the fan located in the fresh food compartment and providing the activation of the air is activated at the fresh food compartment temperature whereat the compressor is deactivated.
  • the activation of the fan is provided.
  • the fresh food compartment temperature whereat the fan is deactivated is lower than the fresh food compartment temperature whereat the fan is activated. After the fan is activated, the fresh food compartment temperature continues to decrease and after some time the fan is deactivated. When the ambient temperature is low, the freezing compartment realizes the compressor deactivation condition later than the fresh food compartment. By keeping small the temperature range whereat the fan is operated, the excessive cooling of the fresh food compartment is prevented.
  • the fan when the fan is not activated during a critical duration predetermined by the producer, at least one heater located in and/or in the vicinity of the fresh food compartment is activated if the fresh food compartment temperature is lower than the fresh food compartment temperature whereat the fan is activated.
  • the fan is provided to be activated by rapidly bringing the fresh food compartment temperature to the fresh food compartment temperature whereat the compressor is deactivated.
  • the heater is deactivated when the fresh food compartment temperature reaches the fresh food compartment temperature whereat the compressor is deactivated.
  • variable speed fan is utilized in the fresh food compartment.
  • the fan is provided to rotate at different speeds at different fresh food compartment temperatures. Consequently, energy saving is provided.
  • the speed of the fan decreases as the fresh food compartment temperature decreases.
  • the fresh food compartment temperature is prevented from decreasing suddenly.
  • the fan is prevented from remaining idle for a long time at low ambient temperatures, thus providing a homogeneous heat distribution in the fresh food compartment.
  • Figure 1 – is the schematic view of a cooling device.
  • the cooling device (1) comprises a fresh food compartment (2) wherein the foodstuff is placed to be cooled, a freezing compartment (3) wherein the foodstuff is placed to be frozen, kept at temperatures lower than that of the fresh food compartment (2), a compressor (4) compressing and circulating the refrigerant in the refrigeration cycle, a fresh food compartment temperature sensor (5) measuring the fresh food compartment (2) temperature, a freezing compartment temperature sensor (6) measuring the freezing compartment (3) temperature, a fan (7) providing air circulation in the fresh food compartment (2) and a control unit (8) ( Figure 1).
  • the cooling device (1) furthermore comprises a control unit (8)
  • the control unit (8) activates the fan (7) at the fresh food compartment temperature (T FANcut-in ) whereat the fan (7) is activated that is equal to the fresh food compartment temperature (T Rcut-out ) whereat the compressor (4) is deactivated.
  • T F fresh food compartment temperature
  • T FANcut-in fresh food compartment temperature
  • T FANcut-in fresh food compartment temperature
  • the control unit (8) deactivates the fan (7) at the fresh food compartment temperature (T FANcut-out ) whereat the fan (7) is deactivated that is lower than the fresh food compartment temperature (T FANcut-in ) whereat the fan (7) is activated. Since the fresh food compartment temperature (T R ) continues to decrease when the freezing compartment temperature (T F ) does not reach the freezing compartment temperature (T Fcut-out ) whereat the compressor (4) is deactivated during the operation of the compressor (4), the fan (7) is deactivated when the fresh food compartment temperature (T FANcut-out ) whereat the fan (7) is deactivated, predetermined by the producer is reached and thus the objects in the fresh food compartment (2) are prevented from overheating.
  • the cooling device (1) comprises a heater (9) that provides the heating of the fresh food compartment (2) when needed.
  • the control unit (8) activates the heater (9) if the fresh food compartment temperature (T R ) is lower than the fresh food compartment temperature (T FANcut-in ) whereat the fan (7) is activated when the fan (7) is not operated for a critical duration (t) predetermined by the producer. Consequently, the fan (7) is prevented from being inactive for a long time and the air distribution in the fresh food compartment (2) is prevented from getting heterogeneous.
  • control unit (8) deactivates the heater (9) when the fresh food compartment temperature (T R ) reaches the fresh food compartment temperature (T FANcut-in ) whereat the fan (7) is activated.
  • the fan (7) is activated as the heater (9) is deactivated and the air in the fresh food compartment (2) is propelled.
  • the rotational speed of the fan (7) can be changed.
  • the fan (7) speed can be determined as required and unnecessary energy consumption is prevented.
  • the rotational speed of the fan (7) decreases as the fresh food compartment temperature (T R ) approaches the fresh food compartment temperature (T FANcut-out ) whereat the fan (7) is deactivated getting away from the fresh food compartment temperature (T FANcut-in ) whereat the fan (7) is activated.
  • the fan (7) is activated at certain intervals, thus providing a homogeneous distribution of the air in the fresh food compartment (2).
  • the fresh food compartment (2) is more effectively cooled.
