Definitions

  • the present invention relates to a cooling device which is heated to prevent frosting.
  • cooling devices at least two compartments kept at different temperatures are provided generally one being the cooling compartment and the other freezing compartment.
  • the cooling compartment is reserved for foods such as fruits and vegetables and the foods are cooled to be stored for a few weeks. Foods required to be stored for a longer period of time are placed in the freezing compartment which is cooled more.
  • cooling of the compartments is realized by different methods.
  • air is cooled by being passed over the evaporator by means of a fan and afterwards circulated inside the freezing compartment and the cooling compartment. Air reaches the evaporator again by passing through the channel situated in the intermediate wall separating the freezing and cooling compartments.
  • the moisture in the heated air delivered from the cooling compartment is condensed and freezes on the air channel and the evaporator.
  • the ice layers accumulated on the air channel and the evaporator are defrosted at certain intervals.
  • the defrosting process is predominantly performed by electric defrost heaters and hence the frequently performed defrost process considerably increases the consumption of energy.
  • sensors are utilized for detecting frosting and defrost heaters are utilized for preventing frosting.
  • defrost heaters are utilized for preventing frosting.
  • the aim of the present invention is the realization of a cooling device which comprises a control unit for preventing frosting.
  • the cooling device cools the foods by means of the refrigerant circulated by the compressor cooling the ambient air in the evaporator and the cooled air being circulated between the compartments by a fan.
  • the fan is operated when the refrigerant is circulated and stops at other times.
  • the cooled air passes through the channel situated in the intermediate wall while passing from the cooling compartment to the freezing compartment.
  • the evaporator is heated by a defrost heater at times when the refrigerant does not pass there through.
  • the cooling device furthermore comprises a control unit which operates the fan, if the fan operation ratio, the temperatures of the compartment and evaporator are within determined intervals.
  • the fan operation ratio determines the compressor operation ratio that is the need for cooling. Consequently, whether or not moisture is accumulated inside the cooling device is detected. If moisture accumulation is detected then the compartment temperatures are controlled to understand whether or not frosting has occurred.
  • the temperature of the defrost heater is checked in order to eliminate frosting and the temperature of the evaporator is checked to detect the fan operation conditions. If all the conditions are favorable, frost is eliminated by operating the fan.
  • the defrost heater is utilized in order to maintain the evaporator temperature.
  • the cooling device has three compartments and the compartments are cooled by different evaporators in order to have different temperature values.
  • the evaporators can be controlled separately by means of at least one valve, the compressor is also operated while the fan operates during the defrosting process by not delivering refrigerant to the evaporator to be defrosted.
  • the frosting is detected from fan operation ratios and the fan is activated in order to take advantage of the heat of the defrost heater for defrosting. Consequently, frosting is effectively detected and energy is saved by the fan delivering the heated air to the evaporator and the channel wherein frosting is detected.
  • Figure 1 - is the sideways schematic view of a cooling device.
  • Figure 2 - is the sideways schematic view of a cooling device comprising three compartments..
  • Figure 3 - is the algorithm of the control unit in an embodiment of the present invention.
  • the cooling device (1) comprises
  • the cooling device (1) furthermore comprises a control unit (10) which
  • T2 cooling compartment (2) temperature
  • T2O predetermined compressor (6) activation temperature
  • the compressor (6) When the compressor (6) operates, the refrigerant is circulated in the refrigeration cycle and cools the environment while passing through the evaporator (5). When the environment reaches the desired temperature (T 2t T3t), the environment is prevented from further cooling by the compressor (6) being stopped. If the environment heats again, the compressor (6) is operated again and the refrigeration cycle continues. During refrigeration, frosting can occur on the evaporator (5) due to the moisture in the environment. Frosting occurs predominantly due to frequent opening of the cooling device (1 ) door or the high temperature of the external environment. When these conditions are met, the temperatures (T2 , T3) of the compartments (2 and 3) also fall and the compressor (6) operates without interruption for a long period of time.
  • the ratio of the minimum operation time (rwt m j n ) is recorded in the memory of the control unit (10) and the ratio of the fan (8) operation time (Fw) getting lower than the ratio of the minimum operation time (Fw tmin) is prevented by operating the fan (8).
  • the control unit (10) operates the defrost heater (9) in order to defrost the evaporator (5).
  • the defrost heater (9) the refrigerant does not pass though the evaporator (5) thus the evaporator (5) is defrosted quickly without condensation thereon.
  • Using the evaporator (5) heat to defrost other places can be achieved only if the cooling air is not circulated in other places.
  • the heated air should not mix in the refrigeration cycle and increase the temperature (T2 or T3) of the compartments (2 and 3).
  • the temperature (T2) of the cooling compartment (2) is measured and if the cooling compartment (2) is sufficiently cool ( ⁇ T2t) then it is deduced that the refrigeration cycle, that is the compressor (6) is not operating.
  • the control unit (10) provides the heated air to be delivered to other frosted places by operating the fan (8) if the evaporator (5) is sufficiently hot and the cooling compartment (2) is sufficiently cold.
  • the control unit (10) prevents frosting of the channel (7) by operating the fan (8).
  • the control unit (10) eliminates the further use of a heating unit for defrosting the channel (7) by operating the fan (8) for delivering the evaporator (5) heat to the channel (7). Consequently, frosting in both the evaporator (5) and the channel (7) is prevented by a single defrost heater (9) ( Figure 1).
  • the control unit (10) operates the defrost heater (9) until it reaches the determined temperature (T5O and operates the fan (8) upon reaching the determined temperature (T5O.
  • the cooling device (1) comprises more than one cooling compartment (2, 102) and a separate evaporator (5, 105, 205) in each of the compartments (2, 102 and 3) and at least one valve (not shown in the figures) which controls the refrigerant delivered to the evaporators (5, 105, 205).
  • the cooling device (1) furthermore comprises the control unit (10) which operates the defrost heater (9) and the fan (8) of the evaporator (5) from the evaporators (5, 105 or 205) whose valve is closed and does not operate the defrost heaters (9) and the fans (8) of the other evaporators (105, 205) whose valves are open.
  • the cooling device (1) is operated according to the following method in an embodiment of the present invention:
  • control unit (10) of the present invention By means of the control unit (10) of the present invention, whether or not frosting has occurred can be detected effectively by monitoring the fan (8) operation ratio. Moreover, the air heated by the defrost heater (9) utilized for defrosting the evaporator (5) can be delivered to other places which might have frosting problem, for example the channel (7) by means of the fan (8). Accordingly, the utilization of additional heater units is not required and savings in costs and energy is provided.
