Description
본 발명은 냉장실의 실내온도가 제어부에 설정된 설정온도 범위를 만족하여 냉장고가 F 사이클로 운전되는 때에 상기 냉장실 또는 저장실의 실내온도가 설정온도 범위의 상한치 온도이상이 되더라도 상기 냉장고를 F 사이클로 계속 운전시키면서 냉장팬을 회전시키도록 하는 2개의 증발기가 설치된 냉장고의 운전 제어 방법에 관한 것이다.According to the present invention, when the indoor temperature of the refrigerating compartment satisfies the set temperature range set in the control unit and the refrigerator operates in the F cycle, the refrigerator is continuously operated in the F cycle even when the indoor temperature of the refrigerating compartment or the storage compartment becomes higher than the upper limit temperature of the set temperature range.

이하, 종래의 냉장고의 운전 방법에 대해 참조도면 도 1을 참조하여 설명하면 다음과 같다.Hereinafter, a method of operating a conventional refrigerator will be described with reference to FIG. 1.
도 1은 종래 2개의 증발기가 설치된 냉장고 시스템을 나타낸 개략도로서 이를 참조하면, 종래 냉장고는 2개의 증발기가 설치된 냉장고로서, 상기 냉장고에는 냉동실, 냉장실 및 저장실이 구비된다.1 is a schematic view showing a conventional refrigerator system having two evaporators, referring to this, the conventional refrigerator is a refrigerator provided with two evaporators, and the refrigerator includes a freezer compartment, a refrigerating compartment and a storage compartment.
상기 냉동실의 일측에는 냉장실용 증발기(7)가 설치되어 냉기를 냉장실에 공급하도록 하고, 상기 냉장실의 일측에는 냉장실용 증발기(7)가 설치되어 냉기를 냉장실 및 저장실에 각각 공급하도록 한다.A refrigerator compartment evaporator 7 is installed at one side of the freezer compartment to supply cold air to the refrigerator compartment, and a refrigerator compartment evaporator 7 is installed at one side of the refrigerator compartment to respectively supply cold air to the refrigerator compartment and the storage compartment.
상기 냉장실과 저장실에는 개폐가능한 댐퍼(미도시)가 각각 설치되어, 상기 각 댐퍼를 제어부에 의해 각각 개폐시킴에 따라 냉장실용 증발기(7)에서 발생된 냉매를 냉장실과 저장실에 공급 및 차단하도록 한다.Opening and closing dampers (not shown) are respectively installed in the refrigerating compartment and the storage compartment, so that the refrigerant generated in the refrigerating compartment evaporator 7 is supplied and blocked to the refrigerating compartment and the storage compartment as the respective dampers are opened and closed by the controller.
또한, 상기 냉동실과 냉장실의 외부에는 압축기(1), 응축기(2), 삼방밸브(3) 및 팽창장치(4,5)가 설치된다.In addition, the compressor (1), the condenser (2), the three-way valve (3) and the expansion device (4, 5) is provided outside the freezing chamber and the refrigerating chamber.
한편, 상기 냉동실과 냉장실 및 저장실에는 각각 온도센서(미도시)가 설치되는데, 상기 온도센서는 냉동실과 냉장실 및 저장실의 실내온도를 감지하여 감지된 정보를 제어부(미도시)에 전달한다.On the other hand, a temperature sensor (not shown) is installed in each of the freezer compartment, the refrigerating compartment, and the storage compartment, and the temperature sensor detects the room temperature of the freezer compartment, the refrigerating compartment, and the storage compartment, and transmits the detected information to the controller (not shown).
상기 제어부(미도시)에는 냉동실과 냉장실 및 저장실이 일정한 범위의 온도를 유지할 수 있도록 각각 대응되는 상한치 온도와 하한치 온도가 설정되데, 이러한 상한치 온도와 하한치 온도 사이의 범위를 이하에서는 냉동실과 냉장실 및 저장실의 설정온도 범위라고 하기로 한다.In the control unit (not shown), the upper limit temperature and the lower limit temperature are respectively set so that the freezer compartment, the refrigerating compartment, and the storage compartment maintain a certain range of temperatures, and a range between the upper limit temperature and the lower limit temperature will be described below. This is referred to as the set temperature range.
이와 같은 2개의 증발기가 설치된 냉장고의 냉각 사이클에 대해 설명하면 다음과 같다.Referring to the cooling cycle of the refrigerator equipped with two evaporators as follows.
상기 압축기(1)에서 압축된 냉매는 응축기(2)에서 응축되고, 상기 응축기(2)에서 응축된 냉매는 삼방밸브(3)에 보내진다.The refrigerant compressed in the compressor (1) is condensed in the condenser (2), the refrigerant condensed in the condenser (2) is sent to the three-way valve (3).
이때, 상기 냉장실 또는 저장실의 실내온도가 설정온도 범위의 상한치 온도 보다 높아지면 상기 삼방밸브(3)는 제어부의 제어에 의해 R/F 사이클 모드로 개방된다.At this time, when the room temperature of the refrigerating compartment or the storage compartment is higher than the upper limit temperature of the set temperature range, the three-way valve 3 is opened in the R / F cycle mode under the control of the control unit.
이와 같이 삼방밸브(3)가 R/F 사이클 모드로 개방되면, 상기 삼방밸브(3)를 통과한 냉매는 제 2 팽창장치(5)를 거쳐 냉장실용 증발기(7)와 냉동실용 증발기(6)를 순차적으로 순환하는 R/F 사이클을 수행한다.When the three-way valve 3 is opened in the R / F cycle mode as described above, the refrigerant passing through the three-way valve 3 passes through the second expansion device 5 and the refrigerating chamber evaporator 7 and the freezing chamber evaporator 6. Perform an R / F cycle that cycles sequentially.
상기 냉장고가 R/F 사이클로 운전되는 중에 상기 냉장실 및 저장실의 실내온도가 설정온도 범위를 만족하게 되면, 상기 냉장고의 삼방밸브(3)는 F 사이클 모드로 개방된다.When the indoor temperature of the refrigerating compartment and the storage compartment satisfies a set temperature range while the refrigerator is operating in an R / F cycle, the three-way valve 3 of the refrigerator is opened in the F cycle mode.
이때, 상기 삼방밸브(3)를 통과한 냉매는 제 1 팽창장치(4)를 거쳐 냉동실용 증발기(6)로 직접 유동되는 F 사이클을 수행한다.At this time, the refrigerant passing through the three-way valve (3) performs an F cycle flowing directly to the freezer compartment evaporator (6) through the first expansion device (4).
이상에서와 같이, 상기 냉장고는 R/F 사이클로 운전될 때에는 냉동실용 증발기(6)와 냉장실용 증발기(7)에 냉매를 공급해야 하는 반면에, 상기 냉장고가 F 사이클로 운전될 때에는 냉동실용 증발기(6)에만 냉매를 공급하면 된다.As described above, the refrigerator needs to supply refrigerant to the freezer compartment evaporator 6 and the freezer compartment evaporator 7 when operated in the R / F cycle, while the freezer compartment evaporator 6 when the refrigerator operates in the F cycle. It is only necessary to supply the refrigerant.
이에 따라, 상기 냉장고는 R/F 사이클로 운전될 때보다 F 사이클로 운전될 때에 소비전력이 보다 적게 소모된다.Accordingly, the refrigerator consumes less power when operated in F cycles than when operated in R / F cycles.
따라서, 상기 냉장고의 소비전력을 감소시키기 위해서는, 상기 냉장고가 R/F 사이클로 운전되는 시간을 보다 단축시키는 것이 요구된다.Therefore, in order to reduce the power consumption of the refrigerator, it is required to shorten the time that the refrigerator is operated in the R / F cycle.
이를 위해, 본 발명은 냉장실의 실내온도가 제어부에 설정된 설정온도 범위를 만족하여 냉장고가 F 사이클로 운전되는 때에 상기 냉장실의 실내온도가 설정온도 범위의 상한치 온도이상이 되더라도 상기 냉장고를 F 사이클로 계속 운전시키면서 냉장팬을 회전시키도록 하여 냉장실의 온도를 낮추어 줌으로써 냉장고의 소비전력을 감소시키도록 하는 것을 그 목적으로 한다.To this end, the present invention is to operate the refrigerator in F cycle even if the indoor temperature of the refrigerator compartment is more than the upper limit temperature of the set temperature range when the refrigerator is operated in F cycle when the indoor temperature of the refrigerator compartment satisfies the set temperature range set in the control unit. The purpose of the present invention is to reduce the power consumption of the refrigerator by rotating the refrigerator fan to lower the temperature of the refrigerator compartment.

상기한 목적을 달성하기 위해, 본 발명은 압축기와 응축기를 순차적으로 통과한 냉매가 삼방밸브를 통해 제 1 팽창장치 및 냉동실용 증발기를 따라 순차적으로 유동되는 F 사이클과; 상기 압축기와 응축기를 순차적으로 통과한 냉매가 삼방밸브를 통해 제 2 팽창장치, 냉장실용 증발기와 냉동실용 증발기를 따라 순차적으로 유동되는 R/F 사이클로 운전되는 2개의 증발기를 갖는 냉장고에 있어서, 상기 냉장고가 F 사이클로 운전되는 중에 냉장실 또는 저장실의 실내온도가 제어부에 저장된 설정온도 범위의 상한치 온도 이상이 되면, 상기 냉장고를 F 사이클로 계속해서 운전시킴과 동시에 냉장실용 증발기의 일측에 설치된 냉장팬을 운전시키고, 냉장실 또는 저장실의 일측에 설치된 댐퍼를 개방시켜,냉장실용 증발기측의 냉기가 냉장팬에 의해 냉장실로 공급되도록 하는 것을 특징으로 하는 2개의 증발기가 설치된 냉장고의 운전 제어 방법을 제공한다.In order to achieve the above object, the present invention includes an F cycle in which the refrigerant passing through the compressor and the condenser sequentially flows sequentially along the first expansion device and the freezer compartment evaporator through the three-way valve; A refrigerator having two evaporators operated by an R / F cycle in which refrigerant passing through the compressor and the condenser sequentially flows through a three-way valve along a second expansion device, a refrigerating chamber evaporator and a freezing chamber evaporator, wherein the refrigerator If the indoor temperature of the refrigerating compartment or the storage compartment becomes higher than the upper limit temperature of the set temperature range stored in the control unit during the F cycle operation, the refrigerator is continuously operated in the F cycle and the refrigerating fan installed at one side of the refrigerating compartment evaporator is operated. A damper provided at one side of a refrigerating compartment or a storage compartment is opened to provide an operation control method for a refrigerator equipped with two evaporators, characterized in that the cold air at the side of the evaporator for the refrigerating compartment is supplied to the refrigerating compartment by a refrigerating fan.
본 발명은 종래의 냉장고와 구성 및 운전 방법이 거의 유사하므로 종래와 동일한 부분에 대해서는 동일한 도번을 부여하고, 종래와 동일한 구성에 대해서는 그 설명을 생략한다.Since the configuration and operation method of the present invention are almost similar to those of the conventional refrigerator, the same parts are given to the same parts as in the prior art, and the description of the same configuration as the conventional one is omitted.
이하, 본 발명에 따른 냉장고의 운전 방법에 대해 참조도면 도 2를 참조하여 설명하면 다음과 같다.Hereinafter, a method of operating a refrigerator according to the present invention will be described with reference to FIG. 2.
도 2는 본 발명에 따른 냉장고의 각 냉각 사이클에서의 압축기 및 각 팬의 작용을 나타낸 선도이다.2 is a diagram showing the operation of the compressor and each fan in each cooling cycle of the refrigerator according to the present invention.
도 2를 참조하면, 상기 냉장고의 냉장실 또는 저장실의 실내온도가 상한치 온도 이상이 되면, 상기 삼방밸브(3)는 제어부(미도시)의 제어에 의해 R/F 사이클 모드로 개방된다.Referring to FIG. 2, when the room temperature of the refrigerator compartment or the storage compartment of the refrigerator is equal to or higher than an upper limit temperature, the three-way valve 3 is opened in the R / F cycle mode under the control of a controller (not shown).
이때, 상기 삼방밸브(3)를 통과한 냉매는 제 2 팽창장치(5)와 냉장실용 증발기(7) 및 냉동실용 증발기(6)를 순차적으로 통과하는 R/F 사이클을 수행한다.At this time, the refrigerant passing through the three-way valve (3) performs an R / F cycle sequentially passing through the second expansion device (5), the refrigerator compartment evaporator (7) and the freezer compartment evaporator (6).
상기 냉장고가 R/F 사이클로 운전되면, 상기 각 증발기의 일측에 설치된 냉동팬(6a) 및 냉장팬(7a)이 운전된다.When the refrigerator is operated in an R / F cycle, the freezing fan 6a and the refrigerating fan 7a installed at one side of each evaporator are operated.
이어, 상기 냉장고가 R/F 사이클로 운전되는 중에 냉장실 및 저장실의 실내온도가 제어부에 저장된 설정온도 범위를 만족하게 되면, 상기 삼방밸브(3)는 F 사이클 모드로 개방된다.Subsequently, when the indoor temperature of the refrigerating compartment and the storage compartment satisfies the set temperature range stored in the controller while the refrigerator is operating in the R / F cycle, the three-way valve 3 is opened in the F cycle mode.
이때, 상기 삼방밸브(3)를 통과한 냉매는 제 1 팽창장치(4) 및 냉동실용 증발기(6)를 순차적으로 통과하는 F 사이클을 수행한다.At this time, the refrigerant passing through the three-way valve (3) performs an F cycle to sequentially pass through the first expansion device (4) and the freezer compartment evaporator (6).
상기 냉장고가 F 사이클로 운전되면, 상기 냉동팬(6a)은 운전되지만냉장팬(7a)은 정지된다.When the refrigerator is operated in an F cycle, the refrigeration fan 6a is operated but the refrigeration fan 7a is stopped.
다음으로, 상기 냉장고의 냉동실과 냉장실 및 저장실의 실내온도가 제어부에 저장된 설정온도 범위를 만족하면, 상기 압축기(1)의 운전이 정지된다.Next, when the room temperature of the freezer compartment, the refrigerating compartment and the storage compartment of the refrigerator satisfies the set temperature range stored in the controller, the operation of the compressor 1 is stopped.
이는 상기 냉동실용 증발기(6)와 냉장실용 증발기(7)에는 더 이상 저온 냉매를 공급할 필요가 없기 때문이다.This is because it is no longer necessary to supply a low temperature refrigerant to the freezer compartment evaporator 6 and the refrigerator compartment evaporator 7.
이때, 상기 냉장팬(7a) 및 냉동팬(6a)이 모두 정지된다는 것은 이해 가능하다.At this time, it is understood that both the refrigeration fan 7a and the refrigeration fan 6a are stopped.
이와 같이 압축기(1)의 운전이 정지된 때에, 상기 냉장고는 외부 공기와 열교환되므로 상기 냉장실과 냉동실 및 저장실의 내부 온도는 점점 상승하게 된다.As such, when the operation of the compressor 1 is stopped, the refrigerator heat exchanges with the outside air, and thus the internal temperatures of the refrigerating compartment, the freezing compartment, and the storage compartment gradually increase.
이에 따라, 상기 냉장실과 저장실의 실내온도가 설정온도 범위를 만족함과 동시에 냉동실의 실내온도가 상한치 온도 이상이 되면, 상기 냉장고는 F 사이클로 운전된다.Accordingly, when the room temperature of the refrigerating compartment and the storage compartment satisfies the set temperature range and the room temperature of the freezing compartment becomes higher than the upper limit temperature, the refrigerator is operated in an F cycle.
상기 냉장고가 F 사이클로 운전되면 다시 냉동실에는 냉기가 공급되므로 냉동실의 실내온도는 낮아지는 반면에, 상기 냉장실 및 저장실에는 냉기가 공급되지 않으므로 냉장실 및 저장실의 실내온도는 점점 높아진다.When the refrigerator is operated in an F cycle, since the cold air is supplied to the freezer compartment again, the indoor temperature of the freezer compartment is lowered, whereas the cold air is not supplied to the refrigerator compartment and the storage compartment, and thus the room temperature of the refrigerator compartment and the storage compartment is gradually increased.
이와 같이, 냉장고가 F 사이클로 운전되는 중에 냉장실 또는 저장실의 실내온도가 설정온도 이상이 되면, 상기 냉장고를 R/F 사이클로 운전시킬 조건이 된다.As described above, when the indoor temperature of the refrigerating compartment or the storage compartment becomes higher than the set temperature while the refrigerator is operating in the F cycle, it is a condition to operate the refrigerator in the R / F cycle.
그러나, 본 발명에 따르면, 상기 냉장고가 F 사이클로 운전되는 중에 냉장실 또는 저장실의 실내온도가 설정온도 이상이 되면, 상기 냉장고를 F 사이클로 계속 운전시킴과 동시에 상기 냉장팬(7a)을 회전시킨다.According to the present invention, however, if the indoor temperature of the refrigerating compartment or the storage compartment becomes higher than the set temperature while the refrigerator is operating in F cycle, the refrigerator is continuously operated in F cycle and the refrigeration fan 7a is rotated.
또한, 상기 냉장실 또는 저장실의 일측에 설치된 댐퍼(미도시)를 개방시킨다.In addition, a damper (not shown) installed at one side of the refrigerating compartment or the storage compartment is opened.
이는 상기 냉장실용 증발기(7)에 위치하는 냉매의 온도가 냉장실 내부 공기의 온도 보다 낮으므로 상기 냉장팬(7a)을 회전시켜 냉장실용 증발기(7)에 위치하는 냉매의 냉기를 냉장실에 공급시키도록 하기 위함이다.This is because the temperature of the refrigerant located in the refrigerating chamber evaporator 7 is lower than the temperature of the air inside the refrigerating chamber so that the refrigerating fan 7a is rotated to supply cool air of the refrigerant located in the refrigerating chamber evaporator 7 to the refrigerating chamber. To do this.
이상에서와 같이, 상기 냉장고의 운전 제어 방법은 R/F 사이클에서 F 사이클로 전환시킬 수는 있지만, F 사이클에서 R/F 사이클로 전환시키지는 않도록 제어하는 것이다.As described above, the operation control method of the refrigerator may be switched from an R / F cycle to an F cycle, but is controlled so as not to switch from an F cycle to an R / F cycle.
이와 같은 방법으로 냉장고의 운전을 제어하면, 상기 냉장고가 R/F 사이클로 운전되는 시간을 단축시킬 수 있으며 상기 냉장실용 증발기(7)에 냉매를 공급하지 않고도 냉장실용 증발기(7)에 위치하는 냉매의 잔여 냉기를 이용할 수 있다.By controlling the operation of the refrigerator in this manner, it is possible to shorten the time that the refrigerator is operated in an R / F cycle, and the refrigerant located in the refrigerator compartment evaporator 7 without supplying the refrigerant to the refrigerator compartment evaporator 7. The remaining chill can be used.
이에 따라, 상기 냉장고의 소비전력을 감소시키고 냉장고의 전체적인 효율을 향상시킬 수 있다.Accordingly, power consumption of the refrigerator may be reduced and overall efficiency of the refrigerator may be improved.
이상에서와 같이, 본 발명은 냉장고가 R/F 사이클로 운전되는 시간을 단축하도록 하여 냉장고의 소비전력을 감소시킬 수 있다.As described above, the present invention can reduce the power consumption of the refrigerator by shortening the time that the refrigerator is operated in the R / F cycle.
또한, 상기 냉장용 증발기에 위치하는 냉매의 잔여 냉기를 이용할 수 있으므로 냉장고의 전체적인 효율을 향상시킬 수 있다.In addition, since the remaining cold air of the refrigerant located in the refrigerating evaporator may be used, the overall efficiency of the refrigerator may be improved.
