본 발명은 독립냉각 방식의 냉장고에 관한 것으로서, 더욱 상세하게는 복수의 구획공간에 대해 각기 증발기를 설치하여 각 구획공간을 보다 신속하게 냉각시 키면서 독립적인 온도제어가 가능하도록 하는 독립냉각 방식의 냉장고에 관한 것이다. The present invention relates to a refrigerator of an independent cooling method, and more particularly, by installing an evaporator for a plurality of compartments to cool each compartment more quickly and to enable independent temperature control. It's about the refrigerator.

일반적으로, 냉장고(100)는 도 1에 나타낸 바와 같이, 압축기(112), 응축기(114), 팽창밸브(116), 증발기(119)를 연결하는 폐회로의 냉매관(111)을 따라 냉매가 지속적으로 순환되는 냉각 사이클을 이용하여 냉기를 생성하고, 이 냉기를 각 실로 공급하여 각 실을 냉각시키게 된다. Generally, as shown in FIG. 1, the refrigerator 100 continuously cools the refrigerant along the refrigerant pipe 111 of a closed circuit connecting the compressor 112, the condenser 114, the expansion valve 116, and the evaporator 119. Cold air is generated using a cooling cycle circulated to the air, and the cold air is supplied to each chamber to cool each chamber.

그 냉각 사이클은, 저온/저압의 기상 냉매를 고온/고압의 기상 냉매로 승온/승압시키는 압축기(112)와, 압축기(112)로부터 유입되는 기상 냉매를 외기에 의해 응축시켜 온도를 저하시킴으로써 액상 냉매로 만들게 되는 응축기(114)와, 응축기(114)로부터 유입되는 액상 냉매를 감압시키는 팽창밸브(116)와, 팽창밸브(116)를 통과한 액상 냉매가 저압상태에서 기화되면서 주변열을 흡수하여 그 주변에 냉기를 생성시키게 되는 증발기(119)와, 이들 장치부들(112, 114, 116, 119)을 연결하면서 냉매가 순환되게 되는 냉매관(111)으로 구성된다. The cooling cycle is a liquid refrigerant by condensing the low-temperature / low-pressure gaseous refrigerant to a high-temperature / high-pressure gas phase refrigerant with a compressor 112, and condensing the gaseous refrigerant flowing from the compressor 112 by outside air to lower the temperature. The condenser 114 to be made of, the expansion valve 116 for reducing the liquid refrigerant flowing from the condenser 114, and the liquid refrigerant passing through the expansion valve 116 is vaporized in a low pressure state to absorb the ambient heat It is composed of an evaporator 119 that generates cold air around the refrigerant pipe, and a refrigerant pipe 111 through which the refrigerant is circulated while connecting the device units 112, 114, 116, and 119.

여기서, 통상 냉장고(100)는 냉동실(102)과 냉장실(104)을 구획되도록 구비하며, 전술한 증발기(119)는 냉동실(102)측 상단부에 설치되게 되고, 전술한 압축기(112)와 응축기(114)는 냉장고(100)의 하단부측에 별도 공간으로 형성되는 기계실(106)내에 설치되게 되며, 기계실(106)내에는 압축기(112)와 응축기(114)를 냉각시키기 위한 냉각팬(115)이 설치되게 된다. Here, the refrigerator 100 is generally provided to partition the freezer compartment 102 and the refrigerating compartment 104, and the above-described evaporator 119 is installed at the upper end of the freezer compartment 102 side, and the compressor 112 and the condenser (described above) 114 is installed in the machine room 106 formed as a separate space at the lower end side of the refrigerator 100, the cooling fan 115 for cooling the compressor 112 and the condenser 114 in the machine room 106 is provided Will be installed.

따라서, 전술한 냉각 사이클이 작동됨에 따라 그 증발기(119)측에서 생성되는 냉기가 분배되어 냉동실(102)과 냉장실(104)내로 공급되게 됨으로써, 각 실 (102, 104) 내부가 소정온도로 냉각되게 되는 것이며, 공급된 냉기는 각 실(102, 104) 내부에서 흐르면서 저장된 식품과 열교환하여 그 온도가 상승되게 되고, 온도가 상승된 냉기는 다시 증발기(119)측으로 귀환되어 재차 적정온도로 냉각된 후 다시 각 실(102, 104)로 공급되는 순환을 반복하게 된다. Therefore, as the above-described cooling cycle is operated, cold air generated at the evaporator 119 side is distributed and supplied into the freezing chamber 102 and the refrigerating chamber 104, thereby cooling the inside of each chamber 102 and 104 to a predetermined temperature. The supplied cold air flows inside the chambers 102 and 104 to exchange heat with the stored food, and the temperature thereof is increased, and the cold air whose temperature is raised is returned to the evaporator 119 again and cooled again to an appropriate temperature. After that, the circulation supplied to each of the chambers 102 and 104 is repeated.

그러나, 이상과 같은 종래의 냉각 시스템에서는 하나의 증발기(119)를 이용하여 2개의 서로 다른 온도대를 구현하게 되고, 특히 증발기(119)가 냉동실(102)측에만 설치되어 있으므로, 냉동실(102)측 상단부에서 생성되는 냉기가 이송되는 과정을 거쳐 냉장실(104)측으로 공급되게 되므로, 냉장실(104)측의 온도변화에 대한 신속한 대응 냉각이 어렵게 되고, 기본적으로 냉동실(102)과 냉장실(104)을 각기 개별적으로 온도제어할 수 없다는 한계성의 문제점이 있었다. However, in the conventional cooling system as described above, two different temperature zones are implemented using one evaporator 119, and in particular, since the evaporator 119 is installed only at the freezing compartment 102 side, the freezing compartment 102 is used. Since the cold air generated in the upper end portion is supplied to the refrigerating chamber 104 side, it is difficult to quickly respond to the temperature change on the refrigerating chamber 104 side, and the freezing chamber 102 and the refrigerating chamber 104 are basically There was a problem of limitation that the temperature could not be controlled individually.

본 발명은 상기와 같은 제반 문제점을 해결하기 위하여 창안된 것으로서, 복수로 구획 형성되는 각 실에 개별적으로 증발기를 설치하여 각 실을 보다 신속하게 냉각시키면서 독립적인 온도제어가 가능하도록 하게 되는 독립냉각 방식의 냉장고를 제공하는데 그 목적이 있다. The present invention has been devised to solve the above problems, and the independent cooling method that allows independent temperature control while cooling each chamber more quickly by installing an evaporator individually in each chamber formed in a plurality of compartments. Its purpose is to provide a refrigerator.

상술한 목적을 달성하기 위한 본 발명의 독립냉각 방식의 냉장고는, 복수로 구획 형성되는 구획공간에 대해 각기 증발기가 구비되고, 냉각 사이클의 압축기, 응축기, 팽창수단 다음에는 상기 복수개의 증발기로 유입되는 냉매의 유량을 분배하기 위한 기액분리기가 구비되는 것을 특징으로 한다. In order to achieve the above object, the independent cooling refrigerator of the present invention includes an evaporator for each partition space formed in a plurality of compartments, and is introduced into the plurality of evaporators after the compressor, the condenser and the expansion means of the cooling cycle. Characterized in that the gas-liquid separator for distributing the flow rate of the refrigerant.

본 발명의 상기 목적과 여러가지 장점은 이 기술분야에 숙련된 사람들에 의 해 첨부된 도면을 참조하여 아래에 기술되는 발명의 바람직한 실시예로부터 더욱 명확하게 될 것이다.The above objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

이하, 첨부된 도면을 참조로 본 발명의 바람직한 실시예를 상세히 설명하기로 한다. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 독립냉각 방식의 냉장고를 설명하기 위한 개략도이다. 2 is a schematic view for explaining a refrigerator of the independent cooling method according to the present invention.

냉장고(200)는 복수로 구획 형성되는 구획공간을 가지며, 일예로 구획공간은 냉장실(204), 냉동실(202), 초저온 냉동실(203)과 같이 3개로 이루어질 수 있다. The refrigerator 200 has a partition space formed in a plurality of compartments. For example, the refrigerator 200 may include three compartments such as a refrigerator compartment 204, a freezer compartment 202, and a cryogenic freezer compartment 203.

본 발명에 따르면, 각 구획공간(204, 202, 203)에 대해 하나씩의 증발기(219a, 219b, 219c)가 개별적으로 구비되게 되어, 해당 구획공간(204, 202, 203)을 개별적으로 신속하게 냉각시킬 수 있으면서 각기 독립적인 온도제어가 가능하도록 하게 되며, 따라서 상대적으로 고온인 냉장실(204)측에는 고온 증발기(219a)가, 상대적으로 저온인 냉동실(202)측에는 저온 증발기(219b)가, 그리고 초저온인 초저온 냉동실(203)측에는 초저온 증발기(219c)가 각각 설치되게 된다. According to the present invention, one evaporator 219a, 219b, and 219c is individually provided for each compartment 204, 202, and 203, so that the compartments 204, 202, and 203 are individually and quickly cooled. It is possible to independently control the temperature, so that the high temperature evaporator 219a on the relatively high temperature freezer compartment 204 side, the low temperature evaporator 219b on the relatively low temperature freezer compartment 202 side, and the ultra low temperature The cryogenic freezer 203 is provided with cryogenic evaporators 219c, respectively.

따라서, 복수개의 증발기(219a~c)를 포함하도록 냉각 사이클이 구성되게 되며, 냉각 사이클은 종래와 기본적으로는 동일하게 압축기(212), 응축기(214), 팽창밸브(216), 복수개의 증발기(219a~c), 이들을 연결하는 냉매관(211), 냉각팬(215)으로 구성되게 되고, 그 작용도 기본적으로 동일하게 된다. Therefore, the cooling cycle is configured to include a plurality of evaporators (219a ~ c), the cooling cycle is basically the same as the conventional compressor 212, condenser 214, expansion valve 216, a plurality of evaporators ( 219a to c), a refrigerant pipe 211 connecting them, and a cooling fan 215, and the action is basically the same.

나아가, 본 발명에서는 복수개의 증발기(219a~c)가 구비되고, 각 증발기 (219a~c)는 서로 다른 온도대의 냉각효과를 제공해야 하므로, 냉각 사이클의 팽창밸브(216) 다음의 냉매관(211)상에는 각 증발기(219a~c)로 공급될 냉매의 유량을 분배하기 위한 기액분리기(217)가 추가로 구비되게 된다. Furthermore, in the present invention, a plurality of evaporators 219a to c are provided, and each of the evaporators 219a to c has to provide a cooling effect at different temperature zones, so that the refrigerant pipe 211 after the expansion valve 216 of the cooling cycle is provided. ) Is further provided with a gas-liquid separator 217 for distributing the flow rate of the refrigerant to be supplied to each evaporator (219a ~ c).

즉, 기액분리기(217)는 기체와 액체의 자중효과에 의한 분리현상에 의해 기상 냉매는 상부측에, 액상 냉매는 하부측에 모이게 되는 것으로, 추후 기화될 액상 냉매가 많이 유입되어 상대적으로 저온을 실현하게 되는 저온 증발기(219b)와 초저온 증발기(219c)측으로 연결되는 분기 냉매관(211b, 211c)은 기액분리기(217)의 하부측에 연결되도록 하고, 액상 냉매가 상대적으로 적게 유입되어야 할 고온 증발기(219a)측으로 연결되는 분기 냉매관(211a)은 그 보다 높은 지점인 기액분리기(217)의 상부측에 연결되도록 하게 된다. That is, the gas-liquid separator 217 collects the gaseous refrigerant at the upper side and the liquid refrigerant at the lower side due to the separation phenomenon caused by the self-weight effect of the gas and the liquid. Branch refrigerant pipes 211b and 211c connected to the low temperature evaporator 219b and the cryogenic evaporator 219c to be realized are connected to the lower side of the gas-liquid separator 217, and the high temperature evaporator to which relatively little liquid refrigerant is introduced. Branch refrigerant pipe 211a connected to the side of 219a is to be connected to the upper side of the gas-liquid separator 217 that is a higher point.

또한, 본 발명에 따르면, 기액분리기(217)로부터 초저온 증발기(219c)로 연결되는 분기 냉매관(211c)상에는 추가로 제2팽창밸브(218)가 구비되어, 흐르는 냉매를 추가적으로 감압하게 되며, 이와 같이 추가적으로 감압시키는 이유는 몰리에르선도(Mollier diagram)상에서 압력이 저하되는 만큼 유체가 저온화되게 된다는 원리를 이용하여 해당 냉매를 보다 저온화시켜 초저온을 실현할 수 있도록 하기 위함이다. In addition, according to the present invention, a second expansion valve 218 is further provided on the branch refrigerant pipe 211c connected to the cryogenic evaporator 219c from the gas-liquid separator 217 to further depressurize the flowing refrigerant. In addition, the reason for the additional pressure reduction is to realize the ultra low temperature by lowering the refrigerant by using the principle that the fluid becomes low temperature as the pressure decreases on the Mollier diagram.

이상과 같은 냉각 사이클의 전반적인 작용을 간략히 설명하면, 압축기(212), 응축기(214), 팽창밸브(216)를 통해 액상 냉매가 기액분리기(217)내로 유입되면, 기액분리기(217)를 통해 복수의 분기 냉매관(211a~c)으로 분배되게 되며, 초저온 증발기(219c)측으로의 분기 냉매관(211c)을 흐르게 되는 냉매는 제2팽창밸브(218) 에서 또한 감압되어 보다 저온화되게 되고, 이후 분배되어 공급된 각 냉매는 각 증발기(219a~c)측에서 상응하는 온도의 냉기를 생성시키게 된다. Briefly describing the overall operation of the cooling cycle as described above, when the liquid refrigerant is introduced into the gas-liquid separator 217 through the compressor 212, the condenser 214, the expansion valve 216, a plurality of gas through the gas-liquid separator 217 The refrigerant flowing through the branch refrigerant pipes 211a to c of the branched refrigerant pipes 211c toward the cryogenic evaporator 219c is further decompressed by the second expansion valve 218 to be lowered. Each of the refrigerants supplied in the distribution generates cold air having a corresponding temperature at each of the evaporators 219a to c.

덧붙여, 이상에서는 구획공간(204, 202, 203)과 증발기(219a~c)가 3개인 경우를 대표적으로 나타내었으나, 이와 다른 복수개로 구비될 수도 있음은 물론이며, 2개의 증발기가 구비되는 경우에는 제2팽창밸브(218)를 이용하지 않고 기액분리기(217)만을 이용하여 구현가능할 것이며, 4개 이상의 증발기가 구비되는 경우에는 세번째부터의 모든 증발기에 대하여 각기 제2팽창밸브를 설치하고 그 개도정도를 서로 다르게 설정하면 될 것이다. In addition, in the above, the case where the partition spaces 204, 202, and 203 and the evaporators 219a to c are three is representatively shown, but may be provided in a plurality of different ones. It is possible to implement using only the gas-liquid separator 217 without using the second expansion valve 218. When four or more evaporators are provided, the second expansion valves are installed for all evaporators from the third and the degree of opening You can set them differently.

그러나, 실질적으로는 팽창밸브의 개도정도를 대폭 줄이면 통과될 수 있는 냉매량이 줄어들게 되므로, 4개 이상은 그 실현이 용이하지 않을 수 있다. However, substantially reducing the degree of opening of the expansion valve greatly reduces the amount of refrigerant that can pass therethrough, so that four or more may not be easy to realize.

또한, 이상에서 냉매를 감압하는데 팽창밸브(216)가 이용되는 것으로 하였으나, 그 대신 모세관과 같은 다른 팽창수단이 이용될 수도 있음은 물론이다. In addition, although the expansion valve 216 is used to decompress the refrigerant above, other expansion means such as a capillary tube may be used instead.

이로써, 본 발명에 의하면, 결국 각 증발기(219a~c)에 서로 상이한 온도의 냉매가 공급되어 서로 다른 온도대를 실현할 수 있게 되는 것이다. Thus, according to the present invention, refrigerants having different temperatures are supplied to each of the evaporators 219a to c, thereby realizing different temperature ranges.

이상, 상기 내용은 본 발명의 바람직한 일 실시예를 단지 예시한 것으로 본 발명의 당업자는 본 발명의 요지를 변경시킴이 없이 본 발명에 대한 수정과 변경을 가할 수 있음을 인지해야 한다. In the foregoing description, it should be understood that those skilled in the art can make modifications and changes to the present invention without changing the gist of the present invention as merely illustrative of a preferred embodiment of the present invention.

본 발명에 따르면, 복수로 구획 형성되는 각 실에 대해 독립적인 냉각이 이루어지게 되므로, 각 실의 온도변화에 대해 보다 신속하게 대응가능하면서 독립적 인 온도제어가 가능하게 되어, 최적의 냉각성능으로 제품의 가치를 향상시키고, 사용자의 요구에 보다 부응할 수 있는 효과가 달성될 수 있다. According to the present invention, since the independent cooling is made for each chamber formed in a plurality of compartments, it is possible to respond more quickly to the temperature change of each chamber, and the independent temperature control is possible, so that the product can be optimally cooled.
