Description
본 발명은 냉장고에 관한 것으로, 특히 절전 및 냉각효율의 향상 및 제조원가의 절감을 동시에 가능하게 하기 위한 냉장고 구조 및 냉각 방법에 관한 것이다.The present invention relates to a refrigerator, and more particularly, to a refrigerator structure and a cooling method for enabling simultaneous power saving and cooling efficiency and reduction of manufacturing cost.
종래의 냉장고는, 도 1에 도시된 바와 같이, 냉장고의 외관을 이루고 내부에 냉동실과 냉장실이 형성된 외부 케이스(1)와, 작동유체인 냉매를 압축하는 압축기(4)와, 압축기(4)로부터 압축된 냉매를 액냉매 상태로 응축시키는 응축기(5)와, 응축기(5)로부터 응축된 액냉매를 2상 냉매로 증발시키는 증발기(6)와, 증발기(6)측으로 공기를 강제 유동시키는 증발기팬(7)을 포함하고 있다.Conventional refrigerators, as shown in Figure 1, forms the exterior of the refrigerator, the outer case 1 having a freezer compartment and a refrigerating compartment therein, a compressor 4 for compressing a refrigerant which is a working fluid, and a compressor from the compressor 4 A condenser 5 for condensing the refrigerant into a liquid refrigerant state, an evaporator 6 for evaporating the liquid refrigerant condensed from the condenser 5 into a two-phase refrigerant, and an evaporator fan forcing the flow of air to the evaporator 6 side ( 7) is included.
상기 압축기(4) 및 응축기(5)는 냉장고의 하부에, 증발기(6)는 냉동실(2)의 후단에 위치한다.The compressor 4 and the condenser 5 are located at the bottom of the refrigerator and the evaporator 6 is located at the rear end of the freezer compartment 2.
또한, 상기와 같이 구성을 가지는 냉장고는 통상 하나의 증발기와 압축기를 가지고 있다.In addition, the refrigerator having the configuration as described above usually has one evaporator and a compressor.
상기와 같이 구성된 냉장고에서 냉장고가 동작되면, 냉매가 압축기(4), 증발기(6), 응축기(5)를 통하여, 압축, 응축, 증발되고, 증발기팬(7)에 의해 증발기(6)측으로 강제 유입된 공기는 증발기(6)의 냉매와 열교환하면서 증발기(6)의 증발잠열로부터 냉기를 얻어 냉동실(2)과 냉장실(3)측으로 정해진 풍량분배비 대로 냉기가 분배된다.When the refrigerator is operated in the refrigerator configured as described above, the refrigerant is compressed, condensed, and evaporated through the compressor 4, the evaporator 6, and the condenser 5, and forced to the evaporator 6 by the evaporator fan 7. The introduced air obtains cold air from the latent heat of evaporation of the evaporator 6 while exchanging heat with the refrigerant of the evaporator 6 and distributes the cold air according to the air volume distribution ratio determined to the freezing chamber 2 and the refrigerating chamber 3 side.
상기와 같이, 냉동실(2) 및 냉장실(3)로 분배된 냉기는 다시 증발기팬(7)의 계속된 회전에 의해 증발기(6)쪽으로 유입되면서 서로 혼합되어 증발기(6) 내의 냉매와 열교환하는 과정을 반복하게 된다.As described above, the cold air distributed to the freezer compartment 2 and the refrigerating compartment 3 is introduced into the evaporator 6 by the continuous rotation of the evaporator fan 7 and mixed with each other to exchange heat with the refrigerant in the evaporator 6. Will be repeated.
그러나, 상기와 같은 종래의 냉장고는 냉장실(3)로부터의 냉기와 냉동실(2)로부터의 냉기가 혼합되면서 냉동실(2)의 냉기는 온도가 상승하게 되고, 증발기(6)에서 다시 냉각되기 때문에 그 만큼의 열효율이 저하된다.However, in the conventional refrigerator as described above, the cold air in the freezer compartment 2 increases in temperature as the cold air from the refrigerator compartment 3 and the cold air from the freezer compartment 2 are cooled, and is cooled again in the evaporator 6. As much as thermal efficiency falls.
한편, 냉장실(3)로 순환되는 냉기는 냉장실(3)이 냉동실(2)에 비해 상당히 높은 온도로 유지되어야 하는데도 냉동실(2)로 순환되는 냉기와 거의 같은 온도대로 순환되므로 불필요한 열교환을 하는 문제점이 있었다.On the other hand, the cold air circulated to the refrigerating compartment 3 is circulated at about the same temperature as the cold circulating to the freezer compartment 2 even though the refrigerating compartment 3 should be maintained at a considerably higher temperature than the freezer compartment 2. there was.
이러한 문제점을 해결하기 위해 도 2와 같이 2개의 증발기(6)(6')를 채용한 구조의 냉장고를 사용하게 되었는데, 2개의 증발기(6)(6')를 냉동실(2)과 냉장실(3) 전용으로 각각 이용하여, 압축기(4)와 증발기(6)를 한 대를 채용한 냉장고보다 절전효율을 상승시키게 된다.In order to solve this problem, a refrigerator having a structure employing two evaporators 6 and 6 'as shown in FIG. 2 is used, and two evaporators 6 and 6' are connected to a freezer compartment 2 and a refrigerating compartment 3. ), Each of which is used exclusively, increases the power saving efficiency than a refrigerator employing one compressor 4 and one evaporator 6.
하지만, 이러한 구조는 증발기(6)를 2개 사용해야 하므로 그에 해당되는 만큼의 제품 단가가 상승되는 문제점이 있었다.However, such a structure has a problem that the product cost as much as it corresponds to the use of two evaporator (6).
따라서, 본 발명은 상기한 같은 문제점을 감안하여 고안된 것으로, 냉동실과 냉장실로 순환되는 냉기가 증발기 내에서 혼합되는 현상을 방지하여 냉장고의 냉동효율 및 절전 효율을 상승시킬 수 있도록 한 냉장고 구조 및 냉각 방법을 제공하는 데 그 목적이 있다.Accordingly, the present invention has been devised in view of the above-mentioned problems, and a refrigerator structure and a cooling method for preventing a phenomenon in which cold air circulated to the freezer compartment and the refrigerating compartment are mixed in the evaporator to increase the freezing efficiency and power saving efficiency of the refrigerator. The purpose is to provide.

이하, 본 발명의 실시예를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 3은 본 발명에 의한 냉장고의 구성을 개략적으로 보인 도면이다.3 is a view schematically showing the configuration of a refrigerator according to the present invention.
도시된 바와 같이, 본 발명에 따른 냉장고는, 냉동실과 냉장실이 형성되고 외관을 이루는 외부 케이스(101)와, 냉매를 압축하기 위한 압축기(104)와, 압축기(104)에서 압축된 냉매를 액냉매 상태로 응축시키는 응축기(105)와, 응축기(105)에서 응축된 액냉매를 2상의 냉매로 증발시키는 과정에서 그 주위의 공기와 열교환을 통해 냉기를 발생시키는 증발기(106)와, 공기를 강제 유입시키는 증발기팬(107)과, 상기 증발기에서 발생된 냉기를 냉동실측으로 유입되도록 하는 냉동실측 냉기 흡/토출구(108)(109)와, 상기 냉기를 냉장실측으로 유입되도록 하는 냉장실측 냉기 흡/토출구(110)(111)를 포함하고 있다.As shown, the refrigerator according to the present invention is a liquid refrigerant containing the outer case 101, the freezer compartment and the refrigerating chamber is formed and the appearance, the compressor 104 for compressing the refrigerant, and the refrigerant compressed by the compressor 104 The condenser 105 to condense in a state, the evaporator 106 for generating cold air through heat exchange with the surrounding air in the process of evaporating the liquid refrigerant condensed in the condenser 105 to the two-phase refrigerant, and forced inflow of air An evaporator fan 107, a freezer compartment side cold air intake / outlet port 108 and 109 for inleting cold air generated in the evaporator to the freezer compartment side, and a cold compartment side cold air intake / outlet port 110 for allowing the cold air to flow into the refrigerating compartment side. (111).
상기 냉동실(102)의 내부에는 온도를 조절하기 위한 온도조절장치(112)가 설치되고, 상기 냉장실(103)의 내부에는 냉장실(103) 내의 온도를 감지하는 온도센서(113)가 마련된다.A temperature control device 112 for adjusting a temperature is installed in the freezing compartment 102, and a temperature sensor 113 for detecting a temperature in the refrigerating compartment 103 is provided in the refrigerating compartment 103.
그리고, 상기 압축기(104), 응축기(105), 증발기(106), 증발기팬(107), 냉동실측 냉기 흡/토출구(108)(109), 냉장실측 냉기 흡/토출구(110)(111) 등은 도시하지 않은 제어부에 의해 작동되도록 된 것이다.The compressor 104, the condenser 105, the evaporator 106, the evaporator fan 107, the freezer compartment cold air intake / discharge port 108, 109, the refrigerating compartment side cold air intake / outlet 110, 111, etc. Is to be operated by a control unit not shown.
상기 냉동실(102)에 마련된 온도조절장치(112)에 의해 설정된 온도를 냉장실(103)에 마련된 온도센서(113)가 감지하는 것에 온도에 의해 제어부는 이미 입력된 온도와 비교함으로써, 상기 압축기(104), 응축기(105), 증발기(106), 증발기팬(107) 등을 작동시킴과 동시에, 냉동실측 냉기 흡/토출구(108)(109), 냉장실측 냉기 흡/토출구(110)(111) 등을 개폐하도록 제어하는 것이다.When the temperature sensor 113 provided in the refrigerating chamber 103 detects the temperature set by the temperature control device 112 provided in the freezing compartment 102, the control unit compares the temperature with the temperature already inputted to the compressor 104. ), The condenser 105, the evaporator 106, the evaporator fan 107, etc., and at the same time, the freezer compartment cold air intake / discharge port 108 (109), the cold compartment side cold air intake / discharge port 110, 111, etc. To control the opening and closing.
여기에서, 상기 압축기(104)와 증발기(106)로 하나로 구성되어 있다.Here, the compressor 104 and the evaporator 106 are composed of one.
이와 같이 구성된 본 발명에 따른 냉장고의 균일 냉각 구조 및 냉각 방법에 따른 작용을 간략하게 설명하면 다음과 같다.The operation according to the uniform cooling structure and the cooling method of the refrigerator according to the present invention configured as described above will be briefly described as follows.
냉장고에 전원이 인가되면, 압축기(104)가 작동되어 냉매가 압축되고, 압축기(104)에 의해 압축된 냉매는 응축기(105)를 지나면서 액냉매로 응축되어 증발기(106)로 유입된다.When power is applied to the refrigerator, the compressor 104 is operated to compress the refrigerant, and the refrigerant compressed by the compressor 104 is condensed into the liquid refrigerant through the condenser 105 and introduced into the evaporator 106.
그러면, 증발기(106)로 유입된 액냉매는 증발기팬(107)에 의해 증발기(106) 측으로 강제 유입된 공기와 열교환 작용에 의해 2상의 냉매로 증발되고, 이 과정에서 흡입공기는 냉기로 전환된다.Then, the liquid refrigerant introduced into the evaporator 106 is evaporated into the two-phase refrigerant by heat exchange action with the air forcedly introduced into the evaporator 106 by the evaporator fan 107, and in this process, the suction air is switched to the cold. .
상기 증발기(106)에서 증발된 2상의 냉매는 다시 압축기(104)로 유입되어 상기와 같은 과정을 반복하게 되는 것이다.(여기에서, 팽창밸브의 작용은 생략하였음)The two-phase refrigerant evaporated from the evaporator 106 is introduced into the compressor 104 again to repeat the above process (here, the action of the expansion valve is omitted).
즉, 냉동실(102)의 온도가 온도조절장치(112)에 의해 설정된 온도보다 높을 경우에 제어부는 압축기(104)를 작동시키기 위해 미리 입력된 온도를 기준으로 압축기(104), 응축기(105), 증발기팬(107), 증발기(106)가 작동하여, 냉기를 발생시킴과 동시에 냉장실측 냉기 흡/토출구(110)(111)는 폐쇄하고, 냉동실측 냉기 흡/토출구(108)(109)는 개방시킨다. 그러면, 냉기는 냉동실(102)과 증발기(106)만을 순환하게 되고, 냉장실(103)의 냉기와는 접촉되지 않게 되는 것이다. 그러므로, 증발기(106) 주위의 냉기 온도가 쉽게 하강하게 된다.That is, when the temperature of the freezer compartment 102 is higher than the temperature set by the thermostat 112, the controller controls the compressor 104, the condenser 105, and the pre-input temperature to operate the compressor 104. The evaporator fan 107 and the evaporator 106 operate to generate cold air, and close the refrigerating chamber side cold air inlet / outlet 110 and 111 and open the freezer compartment side cold air inlet / outlet 108 and 109. Let's do it. Then, the cold air is circulated only in the freezing chamber 102 and the evaporator 106, and the cold air is not in contact with the cold of the refrigerating chamber 103. Therefore, the cold air temperature around the evaporator 106 is easily lowered.
이후에, 냉동실(102)의 내의 온도가 온도조절장치(112)에 의해 설정된 온도보다 낮게 된 경우에는 제어부는 압축기(104)를 정지시키도록 입력되어진 온도에 의해 압축기(104)의 작동을 중지시키고, 냉동실측 냉기 흡/토출구(108)(109)를 폐쇄함과 동시에 냉장실측 냉기 흡/토출구(110)(111)를 개방한다. 그러면, 냉기는 냉장실(103)과 증발기(106) 주위만을 순환하여 냉장실을 냉각시키는 것이다.Subsequently, when the temperature in the freezer compartment 102 becomes lower than the temperature set by the thermostat 112, the controller stops the operation of the compressor 104 by the temperature input to stop the compressor 104. In addition, the freezer compartment side cold air intake / discharge ports 108 and 109 are closed, and the refrigerating compartment side cold air intake / outlet ports 110 and 111 are opened. The cold air then circulates only around the refrigerating chamber 103 and the evaporator 106 to cool the refrigerating chamber.
여기에서, 상기 냉장실(103)의 온도가 통상 영상에서 보존됨으로, 증발기(106)의 잠열을 이용해서 충분히 냉장실(103)을 냉각시킬 수 있는 것이다.Here, since the temperature of the refrigerating compartment 103 is normally stored in the image, the refrigerating compartment 103 can be sufficiently cooled by using the latent heat of the evaporator 106.
한편, 냉장실(103)내의 온도센서(113)가 감지한 온도가 제어부에서 설정된 냉장실의 적정 온도보다 높을 경우에는 제어부는 상기 냉동실측 냉기 흡/토출구(108)(109)를 개방하고, 냉장실측 냉기 흡/토출구(110)(111)는 폐쇄함과 동시에, 압축기(104), 응축기(105)를 작동시켜 냉기를 순환시키게 된다.On the other hand, when the temperature sensed by the temperature sensor 113 in the refrigerating chamber 103 is higher than the appropriate temperature of the refrigerating chamber set by the control unit, the control unit opens the freezer compartment cold air intake / discharge ports 108 and 109, and the refrigerating compartment side cold air. At the same time as the intake / discharge ports 110 and 111 are closed, the compressor 104 and the condenser 105 are operated to circulate cold air.
따라서, 상기 냉장실(103)의 온도가 냉동실(102)의 온도보다 더 빨리 상승되므로, 상기 냉동실(102)의 냉기에 의해 증발기(106) 측의 온도가 신속하게 하강됨으로, 상기 압축기(104), 응축기(105), 증발기팬(107), 증발기(106) 등을 작동시키는 동력을 조금만 사용하여도 되는 것이다.Therefore, since the temperature of the refrigerating compartment 103 rises faster than the temperature of the freezing compartment 102, the temperature of the evaporator 106 side is rapidly lowered by the cold air of the freezing compartment 102, so that the compressor 104, A small amount of power may be used to operate the condenser 105, the evaporator fan 107, the evaporator 106, and the like.
이에 따라, 본 발명에 의하면 냉동실(102)과 냉장실(103)이 독립 냉각이 이루어지기 때문에 냉각효율 및 절전효율을 얻을 수 있고, 아울러 1-압축기, 1-증발기 시스템으로 구동되므로 제조원가를 절감할 수 있는 것이다.Accordingly, according to the present invention, since the freezing chamber 102 and the refrigerating chamber 103 are independently cooled, cooling efficiency and power saving efficiency can be obtained, and the manufacturing cost can be reduced because the system is driven by a 1-compressor and 1-evaporator system. It is.
또한, 제상운전면에 있어서는 종래품의 경우 L-cord Heater Type이나 본 발명에 의한 냉장고의 경우에는 상기의 L-cord Heater Type 적용이 불가하여 복사 전열판식 Heater를 적용하게 되며, 제상시 냉동실 및 냉장실측 냉기 흡/토출구(110/111)를 모두 폐쇄시킨 상태에서 제상운전을 작동시키게 되므로 제상시간 및 입력(소비전력)의 감소가 가능하게 된다.In the defrosting operation surface, the L-cord Heater Type of the conventional products or the L-cord Heater Type of the refrigerator according to the present invention cannot be applied, and thus the radiant heat plate type heater is applied. Since the defrosting operation is operated in a state in which both the cold air intake / outtake ports 110/111 are closed, the defrost time and the input (power consumption) can be reduced.
여기서, 본 발명에 의한 각 부품(증발기, 응축기, 압축기)과 종래품의 단열/냉동부하 및 전열면적을 비교한 실험 결과치를 수학식 1에 나타내었다.Here, an experimental result comparing the heat insulation / freezing load and the heat transfer area of each component (evaporator, condenser, compressor) according to the present invention is shown in Equation 1.
상기의 수학식 1에 나타난 바와 같이 본 발명에 의한 냉장고 각 부품(증발기, 응축기, 압축기)은 종래품에 비해 단열/냉동부하가 약 4/10수준이므로 전열면적 또한 종래품에 비해 약 4/10수준이고, 이에 따라 동일 효과를 낸다고 가정할 때 종래품에 비해 그 크기를 약 4/10만큼 줄일 수 있는 것이다.As shown in Equation 1, each part of the refrigerator (evaporator, condenser, compressor) according to the present invention has a heat insulation / freezing load of about 4/10 level compared to the conventional products, so the heat transfer area is also about 4/10 compared to the conventional products. Level, and assuming that the same effect is achieved, the size can be reduced by about 4/10 compared with the conventional products.
이상에서 설명한 바와 같이 본 발명은 냉기유로가 냉동실측과 냉장실측으로 각각 분리되어 작동하게 되고, 냉동기(압축기) 운전시 냉동실 만이 냉동부하로 작용하게 되므로 냉동사이클 부품들의 사이즈를 줄일 수 있게 되고, 냉동부하가 적어져 실제 냉장고 운전시 단속횟수를 줄일 수 있게 되며, 고온 냉매의 유입에 따른 손실을 저감할 수 있고, 냉동기의 그레이드를 떨어뜨려 입력 감소효과가 두드러지게 나타나므로 냉동 사이클의 효율이 향상되고, 소비전력량도 감소된다.As described above, in the present invention, the cold air flow path is separately operated to the freezing compartment side and the refrigerating compartment side, and only the freezing compartment acts as a freezing load during operation of the freezer (compressor), thereby reducing the size of the refrigeration cycle components and freezing load. It can reduce the number of interruptions during the actual operation of the refrigerator, reduce the loss due to the inflow of high-temperature refrigerant, and reduce the input of the freezer by reducing the grade of the freezer, improving the efficiency of the refrigeration cycle, Power consumption is also reduced.
또한, 냉동실 및 냉장실의 독립 냉동 및 냉장이 가능해져 냉장실의 신선보관이 가능하게 되고, 냉장실과 냉동실의 음식 냄새가 서로 혼합되어 나타나는 냉장실 및 냉동실의 역겨운 냄새도 방지할 수 있는 효과가 있다.In addition, independent freezing and refrigerating of the freezer compartment and the refrigerating compartment is enabled, so that the fresh storage of the refrigerating compartment is possible, and there is an effect of preventing the disgusting smell of the refrigerating compartment and the freezer compartment where the food odors of the refrigerating compartment and the freezer compartment are mixed with each other.
