Description
본 발명은 냉장고의 제어방법에 관한 것으로, 특히 직렬로 연결된 2개의 냉각기가 냉동실과 냉장실에 각각 설치되고 각 실에 설치된 2개의 팬에 의해 각 실의 온도가 독립적으로 제어되는 고효율 독립냉각 싸이클(High efficiency Multi-evaporator cycle:H.M.CYCLE)을 갖는 냉장고의 제어방법에 관한 것이다.The present invention relates to a control method of a refrigerator.

일반적으로 냉장고는, 제1도에 도시한 바와 같이, 중간격벽(1)에 의해 구획된 냉동실(2)과 냉장실(3)을 형성하는 단열구조의 냉장고본체(4)에 냉동실도아(5)와 냉장실도아(6)가 설치되어 구성된다. 제2도에 도시한 바와 같이, 냉동사이클을 수행하기 위한 구성부품인 압축기(7), 응축기(8), 감압기(9), 그리고 냉각기(10)는 냉매관(11)에 의해 차례로 연결되어 폐회로를 구성한다. 이러한 냉장고는, 제2도에 화살표로 나타낸 바와 같이, 냉매관(11)과 냉동사이클 구성부품을 통과하는 냉매의 상태변화에 의해 열을 수수(授受)함으로써 냉동사이클을 수행하는데, 특히 냉각기(10)에서의 냉매의 증발작용에 의해 주위로부터 열을 흡수하여 냉기를 생성한다.In general, the refrigerator includes a freezer compartment 5 and a freezer compartment 5 in an insulated refrigerator body 4 that forms a freezer compartment 2 and a refrigerating compartment 3 partitioned by an intermediate partition 1, as shown in FIG. The refrigerator compartment door 6 is installed and comprised. As shown in FIG. 2, the compressor 7, the condenser 8, the pressure reducer 9, and the cooler 10, which are components for performing the refrigerating cycle, are sequentially connected by the refrigerant pipe 11. Construct a closed circuit. Such a refrigerator performs a refrigeration cycle by receiving heat due to the change of state of the refrigerant passing through the refrigerant pipe 11 and the refrigeration cycle components, as indicated by the arrows in FIG. The evaporation of the refrigerant in) absorbs heat from the surroundings to produce cold air.
제1도를 참조하면, 압축기(7)는 본체(4)의 하측에 설치되고, 냉각기(10)는 냉동실(2)의 후벽에 설치된다. 냉각기(10)의 상측에는 냉각팬(12)이 설치되고, 냉각팬(12)의 전방과 냉장실(3)의 후벽에는 각각 냉기유출구(13)가 형성된 팬가이드(14)와 냉기덕트(15)가 설치된다. 냉각기(10)를 거치면서 열교환된 냉기의 일부는 팬가이드(14)의 냉기유출구(13)를 통해서 냉동실(12)로 공급되고, 나머지 일부는 냉기덕트(15)의 냉기유출구(13)를 통해서 냉장실(3)로 공급된다. 각 실로 공급된 냉기의 귀환을 위해 중간격벽(1)에는 제1귀환로(16)와 제2귀환로(17)가 각각 형성된다. (18)는 냉장실(3)로 공그되는 냉기의 양을 조절하기 위하 조절댐퍼이다.Referring to FIG. 1, the compressor 7 is installed below the main body 4, and the cooler 10 is installed on the rear wall of the freezing chamber 2. A cooling fan 12 is installed above the cooler 10, and a fan guide 14 and a cooling air duct 15 having a cooling air outlet 13 formed in front of the cooling fan 12 and a rear wall of the refrigerating chamber 3, respectively. Is installed. A portion of the cold air heat exchanged while passing through the cooler 10 is supplied to the freezing chamber 12 through the cold air outlet 13 of the fan guide 14, and the remaining part is supplied through the cold air outlet 13 of the cold air duct 15. It is supplied to the refrigerator compartment 3. The first return path 16 and the second return path 17 are respectively formed in the intermediate partition 1 for the return of cold air supplied to each chamber. Reference numeral 18 denotes an adjustment damper for adjusting the amount of cold air to be collected into the refrigerating chamber 3.
다음에는 제3도를 참조하여, 종래의 냉장고의 제어방법을 설명한다. 먼저 압축기의 온,오프의 여부를 결정하기 위해 냉동실의 온도를 검지하여, 냉동실의 온도(TF)와 식품의 냉동보관을 위한 적절한 온도로 미리 정해진 냉동실설정온도(TFS)를 비교 판단한다(단계 110). 단계 110에서 냉동실온도(TF)가 냉동실설정온도(TFS) 보다 높은 경우에는 압축기(7)와 냉각팬(10)을 온(ON)시키고(단계 111), 냉동실온도(TF)가 냉동실설정온도(TFS) 이하인 경우에는 압축기(7)와 냉각팬(10)을 오프(OFF)시킨다(단계 112). 다음에 단계 111과 단계 112 이후에 냉장실온도(TR)와 식품의 냉장보관을 위한 적절한 온도로 미리 정해진 냉장실설정온도(TRS)를 비교하여(단계 113), 냉장실온도(TR)가 냉장실설정온도(TRS)보다 높으면 조절댐퍼(18)를 열고(단계 114), 냉장실온도(TR)가 냉장실설정온도(TRS) 이하이면 조절댐퍼(18)를 닫는다(단계 115).Next, a control method of a conventional refrigerator will be described with reference to FIG. 3. First, the temperature of the freezer compartment is detected to determine whether the compressor is on or off, and the freezer compartment temperature (T F ) is compared with a predetermined freezer compartment set temperature (T FS ) at an appropriate temperature for freezing storage of food ( Step 110). If the freezer compartment temperature T F is higher than the freezer compartment set temperature T FS in step 110, the compressor 7 and the cooling fan 10 are turned on (step 111), and the freezer compartment temperature T F is the freezer compartment. When the temperature is equal to or lower than the set temperature T FS , the compressor 7 and the cooling fan 10 are turned off (step 112). Next, after step 111 and step 112, the refrigerator compartment temperature (T R ) is compared with the predetermined refrigerator set temperature (T RS ) to a suitable temperature for refrigerating food (step 113), so that the refrigerator compartment temperature (T R ) is When the temperature is higher than the set temperature T RS , the control damper 18 is opened (step 114). When the refrigerator compartment temperature T R is equal to or lower than the refrigerator compartment set temperature T RS , the control damper 18 is closed (step 115).
이러한 종래의 냉장고에서 냉장실과 냉동실은 표준 온도조건에서 각각 3℃, -18℃ 정도를 유지하도록 설정되어 있는데, 하나의 열원(냉각기)에서 2개의 온도대역을 제어하는데 한계가 있어 냉장고의 에너지효율을 저하시키는 문제점이 있었다. 즉 하나의 냉각기에 의해서 냉동실과 냉장실을 전술한 소정의 온도대역으로 제어해야 하는데, 냉각기에서 생성된 냉기는 냉동실과 냉장실로 분배되어 공급되므로 냉동실과 냉장실을 함께 신속하게 냉각시키기 어려운 문제점이 있었고, 냉각중에 도어의 잦은 개폐로 어느 실의 급격한 온도상승이 발생할 경우 신속하게 그 실의 냉각을 수행할 수 없는 문제점이 있었다.In the conventional refrigerator, the refrigerator compartment and the freezer compartment are set to maintain about 3 ° C. and −18 ° C. under standard temperature conditions, respectively, and there is a limit to controlling two temperature bands in one heat source (cooler), thereby improving energy efficiency of the refrigerator. There was a problem of deterioration. That is, one freezer controls the freezer compartment and the refrigerating compartment in the above-mentioned predetermined temperature range, and since the cold air generated by the cooler is distributed and supplied to the freezer compartment and the refrigerating compartment, it is difficult to quickly cool the freezer compartment and the refrigerating compartment together. Frequent opening and closing of the door during the sudden temperature rise of any one room there was a problem that can not be quickly cooled.
특히, 종래의 냉장고에서는 냉동실의 냉각기에서 생성된 냉기가 냉기덕트에 의해 안내되고 조절댐퍼에 의해 조절되어 냉장실로 공급되는 복잡한 과정을 거치므로 냉장실의 냉각속도가 늦어지고 동시에 냉장실의 온도변화에 신속하게 대응하지 못하는 문제점이 있었다. 즉, 냉동실에서 생성된 냉기가 냉기덕트를 통해 냉장실로 공급되고, 공급되는 냉기의 양은 조절댐퍼에 의해 제어되므로 냉장실을 소정온도(약 3℃)로 냉각시키는 데는 상당한 시간이 걸린다. 특히 소비자가 최초로 냉장고를 기동시키거나, 장기간 불사용 상태에서 냉장고를 작동시킬 경우, 냉장실은 약 30℃ 정도의 고온상태이므로 약 3℃ 정도의 표준온도로 냉각시키는 데는 상당한 시간이 소요되고, 냉장고의 운전 중에도 냉장실의 온도변화에 신속하게 대응할 수 없으므로 정온냉장을 실현하는 데 한계가 있었다. 이러한 문제점을 해결하기 위해 냉동실과 냉장실에 각각 전용팬모터를 설치한 냉장고가 제안되고 있으나, 이러한 냉장고에서도 냉각기는 냉동실에만 설치되어 있어, 냉동실에서 생성된 냉기가 냉장실로 공급되어야 하므로 냉각속도를 빠르게 하는 데는 한계가 있을 뿐만 아니라 냉동실과 냉장실을 별도로 제어할 수 없는 문제점이 있었다.In particular, in the conventional refrigerator, since the cold air generated in the freezer cooler is guided by the cold air duct, controlled by the control damper, and supplied to the refrigerating compartment, the cooling rate of the refrigerating compartment becomes slow and at the same time rapidly changes in the temperature of the refrigerating compartment. There was a problem that could not respond. That is, since the cold air generated in the freezing chamber is supplied to the refrigerating chamber through the cold air duct, and the amount of cold air supplied is controlled by the control damper, it takes a considerable time to cool the refrigerating chamber to a predetermined temperature (about 3 ° C). In particular, when the consumer starts the refrigerator for the first time or operates the refrigerator without using it for a long time, the refrigerator compartment is in a high temperature of about 30 ° C, and therefore, it takes a considerable time to cool to a standard temperature of about 3 ° C. Even during operation, there was a limit in realizing constant temperature refrigeration because it could not respond quickly to temperature changes in the fridge. In order to solve these problems, refrigerators with dedicated fan motors are proposed in the freezer compartment and the refrigerating compartment, respectively, but in these refrigerators, the cooler is installed only in the freezer compartment, so that the cooling air generated in the freezer compartment must be supplied to the refrigerating compartment to increase the cooling speed. In addition to the limitations, there was a problem that can not control the freezer and refrigerator compartment separately.
따라서, 본 발명은 이러한 문제점들을 해결하기 위한 것으로, 본 발명의 주 목적은 냉동실과 냉장실에 별도의 냉각기를 설치하고 냉동실과 냉장실을 별도로 제어하도록 구성함으로써 각 실을 신속하게 냉각시킬 수 있을 뿐만 아니라 특히 양 실이 모두 불만족일 경우 양 실을 동시에 냉각시킴으로써 양 실 모두 신속하게 설정온도에 도달하게 하는 냉장고의 제어방법을 제공하는 것이다.Accordingly, the present invention is to solve these problems, the main object of the present invention is to provide a separate cooler in the freezer compartment and the refrigerating compartment and to configure the control of the freezer compartment and the refrigerating compartment separately, as well as to quickly cool each room in particular If both chambers are unsatisfactory, a cooling method for the refrigerator is provided by cooling both chambers simultaneously so that both chambers quickly reach a set temperature.
본 발명의 또 다른 목적은 냉장실과 냉동실이 모두 불만족일 경우 기본적으로는 양 실을 동시에 냉각시키되 냉동실 증발기의 온도가 냉동실온도보다 낮은 경우에는 냉동실 증발기의 온도가 냉동실온도보다 낮아질 때까지 냉동실의 냉각을 지연함으로써 동시 냉각에 따른 불필요한 에너지 소비를 방지할 수 있는 냉장고의 제어방법을 제공하는 것이다.Still another object of the present invention is to cool both chambers at the same time when both the refrigerator compartment and the freezer are unsatisfactory, but when the temperature of the freezer compartment evaporator is lower than the freezer compartment temperature, the freezer compartment is cooled until the temperature of the freezer compartment evaporator is lower than the freezer compartment temperature. It is to provide a control method of a refrigerator which can prevent unnecessary energy consumption due to simultaneous cooling by delaying.

이러한 목적을 달성하기 위해 본 발명은, 압축기, 상호 구획된 냉동실과 냉장실을 구비하며, 냉장실에 제1냉각기와 냉장실팬이 설치되고, 냉동실에 제2냉각기와 냉동실팬이 설치된 냉장고의 제어방법을 개시한다. 본 발명의 제어방법에서는 냉동실온도와 식품의 냉동보관을 위한 적절한 온도로 미리 정해진 냉동실설정온도를 비교하고, 냉동실온도가 상기 냉동실설정온도보다 높은 경우에 냉장실온도와 식품의 냉장보관을 위한 적절한 온도로 미리 정해진 냉장실설정온도를 비교하여, 냉장실 온도가 상기 냉장실설정온도보다 높은 경우에 상기 압축기, 냉장실팬, 냉동실팬을 모두 온시켜 냉장실과 냉동실의 동시냉각을 수행한다.In order to achieve the above object, the present invention discloses a control method of a refrigerator having a compressor, a mutually divided freezer compartment and a refrigerating compartment, a first cooler and a refrigerating fan installed in the refrigerating compartment, and a second cooler and a freezer fan installed in the freezer compartment. do.

이하에서는 첨부도면을 참조하면서 본 고안의 바람직한 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the present invention.
먼저, 제4, 5, 6도를 참조하여 본 발명에 따른 냉장고를 설명한다. 제4도에 도시한 바와 같이, 본 발명에 따른 냉장고(20)는 단열구조의 냉장고본체(21)의 내부에 상호간의 냉기혼합이 일어나지 않도록 상호 구획된 하측의 냉동실(22)과 상측의 냉장실(23)이 형성된다. 이러한 냉동실(22)과 냉장실(23)은 중간격벽(24)에 의해 구획되며, 각각 냉동실도아(25)와 냉장실도아(26)에 의해 개폐된다. 즉, 종래의 냉장고와 달리 냉동실과 냉장실을 연통시키는 냉기유로가 없으며, 중간격벽에도 귀환로가 형성되지 않는다. 냉장실(23)의 후벽에는 제1냉각기(27)와 냉장실팬(28)이 설치되며, 냉동실(22)의 후벽에는 제2냉각기(29)와 냉동실팬(30)이 설치된다. 본 명세서에서 냉동실팬과 냉장실팬은 팬모타를 포함하는 개념이다. 그리고 냉장고본체(21)의 하측에 압축기(31)가 설치된다.First, the refrigerator according to the present invention will be described with reference to FIGS. 4, 5, and 6. As shown in FIG. 4, the refrigerator 20 according to the present invention includes a lower freezing compartment 22 and an upper refrigerating compartment which are mutually partitioned so that cold air mixing does not occur inside the refrigerator body 21 having a heat insulating structure. 23) is formed. The freezer compartment 22 and the refrigerating compartment 23 are partitioned by an intermediate partition 24, and are opened and closed by a freezer compartment door 25 and a refrigerating compartment door 26, respectively. That is, unlike the conventional refrigerator, there is no cold air path communicating the freezer compartment and the refrigerating compartment, and no return path is formed in the intermediate partition. The rear wall of the refrigerating chamber 23 is provided with a first cooler 27 and a refrigerating chamber fan 28, and the rear wall of the refrigerating chamber 22 is provided with a second cooler 29 and a freezing chamber fan 30. In the present specification, the freezer compartment fan and the refrigerating compartment fan are concepts including a fan motor. And the compressor 31 is installed below the refrigerator main body 21.
이러한 본 발명에 따른 냉장고의 사이클 구성은 제5도에 도시한 바와 같다. 즉, 압축기(31), 응축기(32), 모세관(33), 그리고 제1냉각기(27)와 제2냉각기(29)가 냉매관(34)에 의해 차례로 연결되어 폐회로를 구성하며, 제1냉각기(27)와 제2냉각기(29)의 부근에는 냉장실팬(28)과 냉동실팬(30)이 각각 설치된다. 특히 제1냉각기(27)와 제2냉각기(29)는 직렬로 배치되어 제1냉각기(27)를 통과한 모든 냉매가 제2냉각기(29)를 통과하도록 구성된다. 냉매는 화살표로 나타낸 바와 같이, 냉매관(34)의 내부를 흐르면서 상태변화를 하며, 특히 제1냉각기(27)와 제2냉각기(29)를 통과하면서 증발되어 이를 통과하는 공기로부터 열을 흡수하여 냉기를 생성한다. 생성된 냉기는 냉장실팬(28)과 냉동실팬(30)의 작동에 의해 냉동실(22)과 냉장실(23)로 공급되는 것이다.The cycle configuration of the refrigerator according to the present invention is as shown in FIG. That is, the compressor 31, the condenser 32, the capillary tube 33, and the first cooler 27 and the second cooler 29 are sequentially connected by the refrigerant pipe 34 to form a closed circuit, and the first cooler The refrigerator compartment fan 28 and the freezer compartment fan 30 are respectively provided in the vicinity of the 27 and the second cooler 29. In particular, the first cooler 27 and the second cooler 29 are arranged in series so that all the refrigerant passing through the first cooler 27 passes through the second cooler 29. As shown by the arrow, the refrigerant changes state as it flows through the inside of the refrigerant pipe 34, and in particular, the refrigerant absorbs heat from the air that is evaporated and passes through the first cooler 27 and the second cooler 29. Create cold air. The generated cold air is supplied to the freezing compartment 22 and the refrigerating compartment 23 by the operation of the refrigerating compartment fan 28 and the freezing compartment fan 30.
이러한 냉장고에서 냉매는 단일(單一)냉매, 예를 들면 CFC-12, 또는 HFC-134a 등이 사용된다. 이러한 냉매의 상변화 과정을 좀더 상세하게 설명하면 다음과 같다. 먼저 압축기(31)에서 냉매는 고온 고압으로 압축되고, 압축된 냉매는 응축기(32)를 흐르면서 주위와의 열교환을 통해 응축된다. 이렇게 응축된 냉매는 모세관(33) 또는 팽창밸브를 통과하면서 감압되어 제1냉각기(27)와 제2냉각기(29)를 통과하면서 증발된다. 제1냉각기(27)와 제2냉각기(29)는 직렬로 배치되어 있고, 이들 사이에는 아무런 구조물이 없으므로 제1냉각기(27)를 통과한 냉매의 전부가 곧바로 제2냉각기(29)를 통과하게 된다. 이때 제1냉각기(27)를 통과하면서 냉매의 일부가 증발되고 제2냉각기(29)를 통과하면서 냉매의 나머지가 증발되어 전부 가스상태로 되는 것이다. 이렇게 증발된 냉매는 압축기(31)에 흡입됨으로써 사이클을 구성하고 이러한 사이클은 압축기의 운전에 따라 반복된다. 한편, 냉매가 증발되면서 냉각기 주위의 공기로부터 열을 흡수하게 되는데, 냉장실팬(28)과 냉동실팬(30)의 운전으로 고내의 공기가 제1냉각기(27)와 제2냉각기(29)를 지나게 되고 열을 빼앗기면서 생성된 냉기는 제4도에 화살표로 도시한 바와 같이, 다시 고내로 공급되어 냉장실과 냉동실을 냉각시키는 것이다.In such a refrigerator, a single refrigerant, for example, CFC-12, HFC-134a, or the like is used. The phase change process of the refrigerant will be described in more detail as follows. First, in the compressor 31, the refrigerant is compressed to high temperature and high pressure, and the compressed refrigerant flows through the condenser 32 to condense through heat exchange with the surroundings. The refrigerant condensed as described above is decompressed while passing through the capillary tube 33 or the expansion valve to be evaporated while passing through the first cooler 27 and the second cooler 29. Since the first cooler 27 and the second cooler 29 are arranged in series, and there is no structure between them, all of the refrigerant passing through the first cooler 27 passes directly through the second cooler 29. do. At this time, a portion of the refrigerant is evaporated while passing through the first cooler 27, and the rest of the refrigerant is evaporated while passing through the second cooler 29, thereby becoming a gas state. The refrigerant evaporated in this way constitutes a cycle by being sucked into the compressor 31, and the cycle is repeated according to the operation of the compressor. On the other hand, the refrigerant is evaporated to absorb heat from the air around the cooler, the operation of the refrigerator compartment fan 28 and the freezer compartment 30 to pass the air in the interior of the first cooler 27 and the second cooler 29. The cold air generated as the heat is taken away is supplied to the inside of the refrigerator again to cool the refrigerating compartment and the freezing compartment, as shown by arrows in FIG.
이와 같이, 2개의 냉각기와 2개의 팬을 가지면서 작동유체로서 단일냉매를 사용하는 시스템을 본 명세서에서 H.M. 싸이클이라 정의한다. 이 H.M. 싸이클은 냉각기들 사이에 기액분리기나 냉매의 유동방향을 제어하기 위한 밸브와 같은 부품이 필요없게 되고 냉각기를 직렬로 배치할 수 있어 냉동사이클을 위한 배관 구성이 매우 단순해진다. 또한 단일냉매를 사용하므로 제조공정에서 혼합냉매 사용시와 같은 냉매 봉입량의 산포에 따른 성능변화가 크지 않아 양산(量産)에 매우 유리하다.As such, a system having two coolers and two fans and using a single refrigerant as the working fluid is described herein in H.M. This is defined as a cycle. This H.M. The cycle eliminates the need for components such as gas-liquid separators or valves to control the flow direction of the coolant between the coolers and allows the chillers to be arranged in series, simplifying the piping configuration for the refrigeration cycle. In addition, since a single refrigerant is used, the performance change according to the dispersion of the refrigerant charge amount as in the case of using a mixed refrigerant in the manufacturing process is not very large, which is very advantageous for mass production.
다음에는 제6도를 참조하여 본 발명의 H.M. 싸이클에 따른 냉장고의 제어부의 구성을 설명한다. 제어부(35)의 입력측에는 도어스위치(36), 냉장실온도센서(37), 냉동실온도센서(38), 외기온도센서(39), 그리고 제1냉각기표면온도센서(40)와 제2냉각기표면온도센서(40')가 접속되어, 도어의 개폐여부, 냉동실의 온도, 냉장실의 온도, 제1냉각기와 제2냉각기의 표면온도를 각각 검지하여 전기신호로써 제어부(35)에 전달한다. 또한 제어부(35)의 출력측에는 압축기(31), 냉장실팬(28) 및 냉동실팬(30)을 각각 온,오프시키기 위한 제1스위치(41)와 제2스위치(42), 그리고 제3스위치(43)가 전기접속되어, 전술한 입력신호에 따라 작동한다. 즉, 제1스위치(41)와 제2스위치(42), 그리고 제3스위치(43)는 상기한 각 센서들로부터 입력된 신호에 따라 스위치제어부(44)에 의해 제어되어 각각 압축기(31)와 냉동실팬(28) 및 냉장실팬(30)을 온,오프시키는 것이다. 따라서 압축기와 냉동실팬 및 냉장실팬을 각각 독립적으로 제어하는 것이 가능하다.Next, referring to FIG. 6, the H.M. The configuration of the controller of the refrigerator according to the cycle will be described. The input side of the control unit 35 has a door switch 36, a refrigerator compartment temperature sensor 37, a freezer compartment temperature sensor 38, an outside air temperature sensor 39, a first cooler surface temperature sensor 40 and a second cooler surface temperature. The sensor 40 'is connected to detect whether the door is opened or closed, the temperature of the freezer compartment, the temperature of the refrigerating compartment, and the surface temperature of the first cooler and the second cooler, respectively, and transmitted to the control unit 35 as an electric signal. In addition, the output side of the control unit 35, the first switch 41, the second switch 42, and the third switch for turning on and off the compressor 31, the refrigerator compartment fan 28 and the freezer compartment fan 30, respectively ( 43 is electrically connected to operate according to the above-described input signal. That is, the first switch 41, the second switch 42, and the third switch 43 are controlled by the switch controller 44 according to the signals input from the above sensors, respectively, so that the compressor 31 and The freezing compartment fan 28 and the refrigerating compartment fan 30 are turned on and off. Therefore, it is possible to independently control the compressor, the freezer compartment fan and the refrigerating compartment fan.
이러한 제어부(35)의 제어방식은 냉동실온도센서(38)에 의해 검지된 냉동실의 온도(TF)와 식품의 냉동보관을 위해 적절한 온도로 미리 정해진 냉동실설정온도(TFS), 그리고 냉장실온도센서(37)에 의해 감지된 냉장실의 온도(TR)와 식품의 냉장보관을 위해 적절한 온도로 미리 정해진 냉장실설정온도(TRS)를 비교함으로써 이루어진다. 본 명세서에서 설정온도라 함은 냉장고 고유의 특성을 유지할 수 있는 고내의 온도대역을 말하는 것으로, 냉동실설정온도(TFS)는 전술한 바와 같이 식품의 냉동보관을 위해 적절한 온도로 미리 정해진 온도로서 -15℃∼-21℃의 범위이다. 즉 냉동실설정온도(TFS)는 이러한 범위내에서, 사용자의 선택에 따라 미리 정해진 -21℃(냉동강), -18℃(냉동중), -15℃(냉동약)의 어느 하나로 정해진다. 또한 냉장실설정온도(TRS)는 전술한 바와 같이 식품의 냉장보관을 위해 적절한 온도로 미리 정해진 온도로서 6℃∼-1℃의 범위이다. 즉 냉장실설정온도(TRS)는 이러한 범위내에서, 사용자의 선택에 따라 미리 정해진 -1℃(냉장강), 3℃(냉장중), 6℃(냉장약)의 어느 하나로 정해진다.The control unit 35 controlled the temperature of the detecting freezing by the freezing compartment temperature sensor 38 in the (T F) and the freezer compartment pre-set at a suitable temperature for the cold storage of food set temperature (T FS), and the fresh food compartment temperature sensor This is done by comparing the temperature T R of the refrigerating compartment sensed by (37) with the predetermined refrigerating compartment set temperature (T RS ) to a temperature suitable for the refrigeration of food. In the present specification, the set temperature refers to a temperature range within the refrigerator capable of maintaining inherent characteristics of the refrigerator, and the freezer setting temperature (T FS ) is a predetermined temperature at a temperature suitable for freezing storage of food as described above. It is the range of 15 degreeC--21 degreeC. That is, the freezer compartment set temperature T FS is set within any one of -21 ° C (freezing steel), -18 ° C (freezing), and -15 ° C (frozen medicine) predetermined according to the user's selection. In addition, the refrigerating chamber set temperature (T RS ), as described above, is in the range of 6 ° C to -1 ° C as a predetermined temperature at a temperature suitable for refrigeration of food. In other words, the refrigerating chamber set temperature (T RS ) is set within one of -1 ° C (refrigerated steel), 3 ° C (refrigerated), 6 ° C (refrigerated medicine) predetermined according to the user's selection.
이하에서는 본 발명에 따른 제어방법의 구체적인 실시예를 도면을 참조하여 설명한다.Hereinafter, a specific embodiment of a control method according to the present invention will be described with reference to the drawings.
[실시예 1]Example 1
실시예 1는 제7도를 참조하여 설명한다. 먼저, 냉동실온도(TF)와 냉동실설정온도(TFS)를 비교한다(단계 211). 단계 211에서 냉동실온도(TF)가 냉동실설정온도(TFS)보다 높은 경우에 냉장실온도(TR)와 냉장실설정온도(TRS)를 비교한다(단계 212). 단계 212에서 냉장실온도(TR)가 냉장실설정온도(TRS)보다 높은 경우에 압축기와 냉동실팬 및 냉장실팬 모두를 온(ON)시킨다(213). 이 경우는 냉동실과 냉장실이 모두 불만족스러운 상태로, 양 실을 동시에 냉각하여 냉장실과 냉동실의 냉각속도를 동시에 향상시킬 수 있다. 이러한 상황은 양 실의 사용빈도가 다같이 과다하거나 주위온도(고외의 온도)가 고온인 경우 또는 냉장고를 장시간 사용하지 않은 경우에 발생한다.Example 1 will be described with reference to FIG. First, the freezer compartment temperature T F and the freezer compartment set temperature T FS are compared (step 211). When the freezer compartment temperature T F is higher than the freezer compartment set temperature T FS in step 211, the refrigerator compartment temperature T R is compared with the refrigerator compartment set temperature T RS (step 212). In operation 212, when the refrigerator compartment temperature T R is higher than the refrigerator compartment set temperature T RS , both the compressor, the freezer compartment fan, and the refrigerator compartment fan are turned on (213). In this case, both the freezer compartment and the refrigerating compartment are in an unsatisfactory state, so that both chambers can be simultaneously cooled to improve the cooling rates of the refrigerating compartment and the freezer compartment. This situation occurs when the frequency of use of both chambers is excessive, the ambient temperature is high, or when the refrigerator is not used for a long time.
단계 212에서 냉장실온도(TR)가 냉장실설정온도(TRS) 이하인 경우에는 압축기와 냉동실팬을 온시키고 냉장실팬을 오프시키며(단계 214), 단계 214에 이어서 단계 212로 되돌아간다. 이 경우는 냉동실은 불만족이나 냉장실은 만족인 상태에서 발생하는 것으로, 압축기와 함께 먼저 냉동실팬이 운전되고 냉동실의 냉각중에 냉장실이 설정온도 이상으로 되면 냉장실팬도 함께 운전된다.If the refrigerator compartment temperature T R is equal to or lower than the refrigerator compartment set temperature T RS in step 212, the compressor and the freezer compartment fan are turned on, and the refrigerator compartment fan is turned off (step 214), and step 214 is followed by step 212. In this case, the freezer compartment is unsatisfactory and the refrigerating compartment is satisfied. The freezer compartment is operated together with the compressor, and the refrigerating compartment fan is also operated when the refrigerating compartment becomes higher than the set temperature during cooling of the freezer compartment.
도한, 단계 213에 이어서 냉동실온도(TF)와 냉동실설정온도(TFS)를 비교한다(단계 215). 단계 215에서 냉동실온도(TF)가 냉동실설정온도(TFS)보다 높은 경우에 단계 212로 되돌아가고, 냉동실온도(TF)가 냉동실설정온도(TFS) 이하인 경우에 압축기와 냉장실팬을 온시키고 냉동실팬을 오프시키는 단계(216)를 진행한다. 이는 단계 213을 진행하는 도중에 냉장실이 설정온도 이하로 냉각되면 냉장실의 냉각을 중단하고 냉동실이 설정온도 이하로 냉각되면 냉동실의 냉각을 중단하기 위한 것이다. 보통은 냉장실의 냉각이 먼저 이루어지기 때문에 냉장실의 냉각이 중단되는 전술한 단계 214와 같은 상황이 발생한다.Further, following step 213, the freezer compartment temperature T F and the freezer compartment set temperature T FS are compared (step 215). In step 215, if the freezer temperature T F is higher than the freezer set temperature T FS , the process returns to step 212, and if the freezer temperature T F is below the freezer set temperature T FS , the compressor and the refrigerating fan are turned on. In step 216, the freezer compartment fan is turned off. This is to stop the cooling of the refrigerating compartment when the refrigerating compartment cools below the set temperature during the step 213 and to stop the cooling of the freezing compartment when the freezing compartment cools below the preset temperature. Since the cooling of the refrigerating compartment is usually performed first, a situation such as step 214 described above, in which the refrigerating compartment is stopped, occurs.
한편, 단계 211에서 냉동실온도(TF)가 냉동실설정온도(TFS) 이하인 경우에 냉장실온도(TR)와 냉장실설정온도(TRS)를 비교하고(단계 217), 단계 217에서 냉장실온도(TR)가 냉동실설정온도(TFS)보다 높은 경우에 압축기와 냉장실팬은 온시키고 냉동실팬을 오프시키며(단계 216), 단계 217에서 냉장실온도(TR)가 냉장실설정온도(TRS) 이하인 경우에는 압축기, 냉동실팬과 냉장실팬을 정지시킨다(단계 218).On the other hand, when the freezer compartment temperature T F is less than or equal to the freezer compartment set temperature T FS in step 211, the refrigerator compartment temperature T R and the refrigerator compartment set temperature T RS are compared (step 217), and the refrigerator compartment temperature ( If T R ) is higher than the freezer set temperature (T FS ), the compressor and the fridge fan are turned on and the freezer fan is turned off (step 216), and in step 217 the fridge temperature (T R ) is below the freezer set temperature (T RS ). In the case, the compressor, the freezer compartment fan and the refrigerating compartment fan are stopped (step 218).
단계 216에 이어서 냉장실온도(TR)와 냉장실설정온도(TRS)를 비교하고(단계 219), 단계 219에서 냉장실온도(TR)가 냉장실설정온도(TRS) 이하인 경우에는 단계 211로 되돌아가고, 냉장실온도(TR)가 냉장실설정온도(TRS)보다 높은 경우에 냉동실온도(TF)와 냉동실설정온도(TFS)를 비교하고(단계 220), 단계 220에서 냉동실온도(TF)가 냉동실설정온도(TFS)보다 높은 경우에 단계 212로 되돌아가고, 냉동실온도(TF)가 냉동실설정온도(TFS) 이하인 경우에 압축기와 냉장실팬을 온시키고 냉동실팬을 오프시키는 단계(단계 216)로 되돌아간다.Following step 216, the refrigerator compartment temperature T R and the refrigerator compartment set temperature T RS are compared (step 219), and if the refrigerator compartment temperature T R is less than or equal to the refrigerator compartment set temperature T RS in step 219, the process returns to step 211. When the refrigerator compartment temperature (T R ) is higher than the refrigerator compartment set temperature (T RS ), the freezer compartment temperature (T F ) is compared with the freezer compartment set temperature (T FS ) (step 220), and in step 220 the freezer compartment temperature (T F) ) Returns to step 212 when the freezer set temperature (T FS ) is higher, and turns on the compressor and the freezer fan and turns off the freezer fan when the freezer temperature (T F ) is below the freezer set temperature (T FS ) ( Return to step 216).
한편, 단계 218에 이어서 제1냉각기표면온도(TES)가 0℃ 보다 높은가를 비교판단한다(단계 221). 단계 221에서 제1냉각기표면온도(TES)가 0℃ 이하인 경우에는 압축기와 냉동실팬을 오프시키고 냉장실팬만을 온시켜(단계 222) 냉장실증발기인 제1냉각기의 제상을 수행한다. 즉, 냉동실과 냉장실의 만족 상태에서 압축기를 오프한 직후에 냉장실팬만의 작동으로 제1냉각기의 제상을 수행하는 것이다. 이는 압축기 오프 직후에 냉장실의 온도가 제1냉각기의 표면온도보다 높은 점을 이용한 것으로, 압축기 오프 직후에 냉장실팬만을 운전시킴으로써 상대적으로 고온인 냉장실의 공기가 제1냉각기를 통과하게 하여 제1냉각기의 제상을 수행함과 동시에 냉장실의 냉각도 수행하는 것이다. 따라서 별도의 전기히터를 사용하지 않아도 되므로 소비전력을 감소시킬 수도 있고 전기히터의 사용에 따른 과도한 온도상승을 방지할 수도 있다.On the other hand, after step 218, it is determined whether the first cooler surface temperature T ES is higher than 0 ° C (step 221). When the first cooler surface temperature T ES is 0 ° C. or lower in step 221, the compressor and the freezer compartment fan are turned off and only the refrigerator compartment fan is turned on (step 222) to perform defrosting of the first cooler which is a refrigerator compartment evaporator. That is, the defrosting of the first cooler is performed by the operation of the refrigerator compartment fan only immediately after the compressor is turned off in the satisfied state of the freezer compartment and the refrigerator compartment. This is because the temperature of the refrigerating compartment is higher than the surface temperature of the first cooler immediately after the compressor is turned off. By operating only the refrigerating compartment fan immediately after the compressor is turned off, the air of the refrigerating compartment having a relatively high temperature passes through the first cooler, thereby Simultaneous defrosting and cooling of the refrigerating compartment is performed. Therefore, it is not necessary to use a separate electric heater can reduce power consumption or prevent excessive temperature rise due to the use of the electric heater.
이상과 같이, 본 발명의 H.M. 싸이클의 실시예 1은 주로 냉동실과 냉장실 모두가 불만족 상태에 있는 경우 양 실을 동시냉각하여 양 실의 냉각속도를 동시에 향상시키는데 이점이 있다. 물론 냉동실은 불만족이나 냉장실이 만족한 상태에 있으면 냉동실의 냉각을 먼저 수행하고 반대로 냉동실은 만족되었으나 냉장실이 불만족상태에 있으면 냉장실의 냉각을 먼저 수행할 수도 있다.As described above, the H.M. of the present invention. The first embodiment of the cycle has an advantage to improve the cooling rate of both chambers simultaneously by simultaneously cooling both chambers when both the freezer compartment and the refrigerator compartment are in an unsatisfactory state. Of course, if the freezer is dissatisfied or the fridge is in a satisfactory state, the freezer compartment is cooled first. On the contrary, if the freezer is satisfied, the freezer compartment may be cooled first.
[실시예 2]Example 2
실시예 2는 실시예 1의 변형예이다. 제8도를 참조하면, 먼저, 냉동실온도(TF)와 냉동실설정온도(TFS)를 비교한다(단계 231). 단계 231에서 냉동실온도(TF)가 냉동실설정온도(TFS)보다 높은 경우에 냉장실온도(TR)와 냉장실설정온도(TRS)를 비교한다(단계 232). 단계 232에서 냉장실온도(TR)가 냉장실설정온도(TRS)보다 높은 경우에는 냉동실온도(TF)와 제2냉각기표면온도(TFE)를 비교하여(단계 233), 냉동실온도(TF)가 제2냉각기표면온도(TFE)보다 높으면 압축기와 냉동실팬 및 냉장실팬을 온(ON)시키고(단계 234), 그렇지 않은 경우에는 압축기와 냉장실팬은 온(ON)시키고 냉동실팬은 오프(off)시킨다(단계 235). 즉 냉동실과 냉장실이 다같이 불만족 상태에 있는 경우에 압축기와 냉동실팬 및 냉장실팬을 온(ON)시키는 단계 234를 수행하여 양 실을 모두 냉각시키는 것이다. 다만 이 경우 양 실을 모두 냉각시키기 전에 냉동실온도와 냉동실 증발기인 제2냉각기의 표면온도(구체적으로는 제2냉각기표면온도보다 1∼5℃가 더 높은 온도)를 비교하여 제2냉각기표면온도가 냉동실의 온도보다 높을 때는 냉동실팬의 온(ON) 시점을 소정시간 지연시켜 에너지를 절약하는 것이다. 이러한 상황은 정상운전 후 압축기 오프 상태에서 고온 고압의 응축기와 모세관의 잔류냉매가 제1냉각기와 제2냉각기로 유입되어 특히 냉동실 증발기인 제2냉각기의 온도가 냉동실온도보다 높은 상태로 되는 경우에 발생하는 것으로, 이때도 냉동실팬을 운전시키면 오히려 냉동실의 온도를 상승시키는 역효과가 발생하므로 제2냉각기의 온도가 냉동실의 온도보다 더 낮아질 때까지 냉동실팬의 운전을 지연하는 것이다.Example 2 is a modification of Example 1. Referring to FIG. 8, first, the freezer compartment temperature T F and the freezer compartment set temperature T FS are compared (step 231). In step 231, when the freezer compartment temperature T F is higher than the freezer compartment set temperature T FS , the refrigerator compartment temperature T R is compared with the refrigerator compartment set temperature T RS (step 232). If the refrigerator compartment temperature T R is higher than the refrigerator compartment set temperature T RS in step 232, the freezer compartment temperature T F and the second cooler surface temperature T FE are compared (step 233), and the freezer compartment temperature (T F). ) Is above the second chiller surface temperature (T FE ), the compressor, freezer fan and refrigerating fan are turned on (step 234), otherwise the compressor and refrigerating fan are turned on and the freezer fan is turned off ( off) (step 235). That is, when both the freezer compartment and the refrigerating compartment are in an unsatisfactory state, step 234 of turning on the compressor, the freezer compartment and the refrigerating compartment fan is performed to cool both chambers. In this case, however, the surface temperature of the second cooler is increased by comparing the freezer temperature with the surface temperature of the second cooler, which is a freezer evaporator (specifically, 1 to 5 ° C. higher than the second cooler surface temperature) before cooling both chambers. When the temperature is higher than the temperature of the freezer compartment, the ON point of the freezer compartment fan is delayed for a predetermined time to save energy. This situation occurs when the residual refrigerant in the condenser and capillary tube of the high temperature and high pressure flows into the first cooler and the second cooler in the compressor off state after the normal operation, and the temperature of the second cooler, which is the freezer compartment evaporator, becomes higher than the freezer temperature. In this case, since the adverse effect of increasing the temperature of the freezing compartment occurs when the freezing compartment fan is operated, the operation of the freezing compartment fan is delayed until the temperature of the second cooler becomes lower than the temperature of the freezing compartment.
또한, 단계 232에서 냉장실온도(TR)가 냉장실설정온도(TRS) 이하인 경우에도 냉동실온도(TF)와 제2냉각기표면온도(TFE)를 비교하여(단계 236), 냉동실온도(TF)가 제2냉각기표면온도(TFE)(구체적으로는 제2냉각기표면온도(TFE)보다 2℃ 높은 온도)보다 높으면 압축기와 냉동실팬은 온시키고 냉장실팬은 오프시키며(단계 237), 그렇지 않은 경우에는 냉동실팬과 냉장실팬을 오프시키고 압축기만을 온시킨다(단계 238). 즉, 냉동실은 불만족 상태이고 냉장실은 만족상태인 경우에도, 냉동실온도와 제2냉각기의 온도를 비교하여 냉동실팬의 운전여부를 결정하는 것이다. 단계 237과 238에 이후에는 최초의 단계 231로 되돌아간다.Further, even when the refrigerator compartment temperature T R is equal to or lower than the refrigerator compartment set temperature T RS in step 232, the freezer compartment temperature T F and the second cooler surface temperature T FE are compared (step 236), and the freezer compartment temperature T F ) is higher than the second cooler surface temperature T FE (specifically 2 ° C. higher than the second cooler surface temperature T FE ), the compressor and freezer fan are turned on and the refrigerating fan is turned off (step 237), Otherwise, the freezer compartment fan and the refrigerating compartment fan are turned off and only the compressor is turned on (step 238). That is, even when the freezer compartment is in an unsatisfactory state and the refrigerator compartment is in a satisfied state, the operation of the freezer compartment fan is determined by comparing the freezer compartment temperature with the temperature of the second cooler. Steps 237 and 238 then return to the original step 231.
한편, 단계 231에서 냉동실온도(TF)가 냉동실설정온도(TFS) 이하인 경우에 냉장실온도(TR)와 냉장실설정온도(TRS)를 비교하여(단계 239), 냉장실온도(TR)가 냉장실설정온도(TRS)보다 높으면 압축기와 냉장실팬은 온시키고 냉동실팬을 오프시키고(단계 235), 냉장실온도(TR)가 냉장실설정온도(TRS) 이하인 경우에는 압축기, 냉동실팬과 냉장실팬을 정지시킨다(단계 240).On the other hand, when the freezer compartment temperature T F is equal to or lower than the freezer compartment set temperature T FS in step 231, the refrigerator compartment temperature T R and the refrigerator compartment set temperature T RS are compared (step 239), and the refrigerator compartment temperature T R. If the refrigerator is above the refrigerator set temperature (T RS ), the compressor and the refrigerator compartment fan are turned on and the freezer fan is turned off (step 235). If the refrigerator compartment temperature (T R ) is below the refrigerator compartment set temperature (T RS ), the compressor, the refrigerator compartment fan and the refrigerator compartment are Stop the fan (step 240).
단계 240에 이어서 제1냉각기의 제상을 수행하는 것은 전술한 실시예와 동일하므로 이에 대한 설명은 생략한다.Defrosting the first cooler subsequent to step 240 is the same as the above-described embodiment, and thus description thereof will be omitted.
한편, 단계 235와 단계 234에 이어서 냉동실온도(TF)와 냉동실설정온도(TFS)를 비교하고(단계 241), 단계 241에서 냉동실온도(TF)가 냉동실설정온도(TFS)보다 높은 경우에 단계 233로 되돌아가고, 냉동실온도(TF)가 냉동실설정온도(TFS) 이하인 경우에 냉장실온도(TR)와 냉장실설정온도(TRS)를 비교하여(단계 242), 냉장실온도(TR)가 냉장실설정온도(TRS)보다 높은 경우에는 단계 235로 되돌아가고, 냉장실온도(TR)가 냉장실설정온도(TRS) 이하인 경우에는 단계 240을 진행한다.On the other hand, following step 235 and step 234, the freezer compartment temperature T F and the freezer compartment set temperature T FS are compared (step 241), and in step 241 the freezer compartment temperature T F is higher than the freezer compartment set temperature T FS . The process returns to step 233, and compares the refrigerator compartment temperature T R and the refrigerator compartment set temperature T RS when the freezer temperature T F is less than or equal to the freezer set temperature T FS (step 242). If T R ) is higher than the refrigerator compartment set temperature T RS , the process returns to step 235, and if the refrigerator compartment temperature T R is equal to or less than the refrigerator compartment set temperature T RS , step 240 is performed.
본 실시예는 전술한 실시예와 동일하게 냉동실과 냉장실이 다같이 불만족 상태에 있는 경우에 기본적으로는 양 실을 모두 냉각시킨다. 다만 양 실을 모두 냉각시키기 전에 냉동실온도와 냉동실 증발기인 제2냉각기의 표면온도를 비교하여 제2냉각기표면온도가 냉동실의 온도보다 높을 때는 냉동실팬의 온(ON) 시점을 소정시간 지연시켜 에너지를 절약하는 것에 특징이 있다.This embodiment basically cools both chambers when the freezer compartment and the refrigerating compartment are both in an unsatisfactory state as in the above-described embodiment. However, before cooling both chambers, the temperature of the freezer compartment is compared with the surface temperature of the second cooler, which is the freezer compartment evaporator. When the surface of the second cooler is higher than the temperature of the freezer compartment, the ON time of the freezer compartment fan is delayed for a predetermined time. It is characterized by saving.
이상에서 상세히 설명한 바와 같이, 본 발명에서는 냉동실과 냉장실에 별도의 냉각기를 설치하고 냉동실과 냉장실을 별도로 제어하도록 구성함으로써 각 실을 신속하게 냉각시킬 수 있을 뿐만 아니라 특히 양 실이 모두 불만족일 경우 양 실을 동시에 냉각시킴으로써 양 실 모두 신속하게 설정온도에 도달하게 할 수 있다.As described in detail above, in the present invention, by installing separate coolers in the freezer compartment and the refrigerating compartment and controlling the freezer compartment and the refrigerating compartment separately, each chamber can be cooled quickly, and in particular, both rooms are unsatisfactory. By simultaneously cooling both chambers, both chambers can be quickly reached the set temperature.
또한, 냉장실과 냉동실이 모두 불만족일 경우 기본적으로는 양 실을 동시에 냉각시키되 냉동실 증발기의 온도가 냉동실온도보다 낮은 경우에는 냉동실증발기의 온도가 냉동실온보다 낮아질 때까지 냉동실의 냉각을 지연함으로써 동시 냉각에 따른 불필요한 에너지 소비를 방지할 수 있다.In addition, if both the fridge and the freezer are dissatisfied, the two chambers are cooled at the same time, but if the temperature of the freezer evaporator is lower than the freezer temperature, the cooling of the freezer compartment is delayed until the temperature of the freezer evaporator is lower than the freezer temperature. Unnecessary energy consumption can be prevented.
