Description

김치냉장고의 독립제어용 냉각 사이클{A COOLING CYCLE FOR INDEPENDENT CONTROL OF KIMCHI REFRIGERATOR}COOLING CYCLE FOR INDEPENDENT CONTROL OF KIMCHI REFRIGERATOR}

본 발명은 김치냉장고의 독립제어용 냉각 사이클에 관한 것으로서, 보다 상세하게는 2개 이상의 보관실을 가지는 김치냉장고에서 각각의 보관실을 독립적으로 냉각 제어하되 열효율을 높일 있도록 하는 김치냉장고의 독립제어용 냉각 사이클에 관한 것이다.The present invention relates to a cooling cycle for independent control of kimchi refrigerator, and more particularly to a cooling cycle for independent control of kimchi refrigerator to increase the thermal efficiency of each kimchi refrigerator independently in the kimchi refrigerator having two or more storage compartments. will be.

김치냉장고는 보통 2개 이상의 보관실을 가지고 있는데, 모든 보관실을 통일되게 제어하기도 하지만 각각의 보관실이 보관하는 음식이 다르고 외부와 노출되는 빈도도 다르기 때문에 독립적으로 냉각제어하는 것이 일반적이다.Kimchi refrigerators usually have more than two storage rooms. Although all the storage rooms are uniformly controlled, it is common to control them independently because the food stored in each storage room is different and the frequency of exposure to the outside is different.

도 1에 도시한 바와 같이, 종래에는 김치냉장고(10)를 구성하는 복수의 보관실(1) 주위에 증발기(2)가 각각 설치되어 있고, 취합통로부(3)에서 이들 증발기(2)의 출구가 취합되는 구성으로 되어 있었다.As shown in FIG. 1, conventionally, an evaporator 2 is provided around a plurality of storage chambers 1 constituting the Kimchi refrigerator 10, and an outlet of these evaporators 2 from the collecting passage part 3 is provided. It was a configuration that is collected.

특히, 상기 취합통로부(3)와 각각의 증발기(2) 출구 사이에는 흡입파이프(4)(5)가 각각 설치되어 있으며 충분한 열교환을 위해 그 길이가 1000mm 이상 연장될 필요가 있다. 보통, 상기 흡입파이프(4)(5)는 코일 형태로 구성되어 있다.In particular, suction pipes 4 and 5 are respectively provided between the collecting passage part 3 and the outlets of the respective evaporators 2, and their lengths need to be extended by 1000 mm or more for sufficient heat exchange. Usually, the suction pipes 4 and 5 are configured in the form of coils.

도 2에는 이러한 구성이 개략적으로 도시되어 있다. 도시된 바와 같이, 압축기(7)와 응축기(8)를 거친 후 양쪽으로 분기되어 각각 팽창기(9)와 증발기(2)를 지나 흡입파이프(4)(5)를 통과하고 취합통로부(3)에서 모아진 다음 압축기(7)로 되돌아가게 되어 있다.This configuration is schematically illustrated in FIG. As shown, after passing through the compressor (7) and the condenser (8) and branches to both sides through the inflator (9) and evaporator (2), respectively, through the suction pipe (4) (5) and collecting passage section (3) Collected at and then returned to the compressor (7).

이와 같이, 종래에는 2개 이상의 보관실을 독립적으로 냉각 제어하는 경우 1000mm 이상의 흡입파이프가 보관실 수만큼 필요하게 되므로 재료비가 많이 소요되었다.As such, in the related art, when two or more storage chambers are independently cooled and controlled, suction pipes of 1000 mm or more are required as much as the number of storage chambers.

또한, 종래에는 증발기들이 각각 흡입파이프를 경유하여 연결되어 있어 상호 열적인 영향을 주지 못하기 때문에 효율을 높이기가 어려웠다. 즉, 모든 보관실의 온도가 소정치 이하로 내려가 압축기가 off되는 순간부터 보관실의 온도는 상승하는데, 온도 상승속도가 큰 보관실에 의해 소정의 온도에 도달하는 경우 바로 압축기가 on되므로 압축기가 빈번하게 작동하게 됨으로써 김치냉장고의 효율이 크게 저하하게 되었다.In addition, in the related art, since the evaporators are connected to each other via the suction pipe, it is difficult to increase the efficiency because they do not have mutual thermal effects. In other words, the temperature of all the storage rooms drops below the predetermined value and the temperature of the storage room rises from the moment when the compressor is turned off. As a result, the efficiency of the kimchi refrigerator is greatly reduced.

본 발명은 전술한 문제점을 해결하기 위해 안출된 것으로서, 발명의 목적은 흡입파이프를 1개만 구성하도록 하여 재료비를 절감하고 각 보관실에 설치된 증발기 사이의 열전도를 이용하여 열적 효율을 향상시킬 수 있는 김치냉장고의 독립제어용 냉각 사이클을 제공하는데 있다.The present invention has been made to solve the above problems, the object of the invention is to make only one suction pipe to reduce the material cost and to improve the thermal efficiency by using the thermal conductivity between the evaporator installed in each storage compartment It is to provide a cooling cycle for independent control of the.

전술한 목적을 달성하기 위해, 본 발명은 복수의 보관실이 형성된 김치냉장고의 독립제어용 냉각 사이클로서, 압축기, 상기 압축기에 연결된 응축기, 상기 응축기로부터 각 보관실로 분기되어 설치된 팽창기와 증발기, 상기 각 증발기의 출구가 함께 연결되어 냉매가 모여져서 통과하는 취합통로부 및, 상기 취합통로부의 출구와 압축기 사이에 설치된 단일의 흡입파이프를 포함하는 것을 특징으로 한다.In order to achieve the above object, the present invention is a cooling cycle for independent control of the Kimchi refrigerator having a plurality of storage chambers, the compressor, the condenser connected to the compressor, the expander and evaporator branched from each condenser to the storage chamber, each of the evaporator It is characterized in that it comprises a collecting passage portion through which the outlet is connected together and the refrigerant gathers and passes, and a single suction pipe provided between the outlet of the collecting passage portion and the compressor.

이 경우, 상기 취합통로부와 각 증발기 출구 사이는 100~200mm의 중간파이프에 의해 연결되어 있는 것을 특징으로 한다.In this case, the collecting passage portion and each evaporator outlet is characterized in that it is connected by an intermediate pipe of 100 ~ 200mm.

전술한 바와 같은 구성의 본 발명에 따르면, 흡입파이프를 1개만 구성하도록 하여 재료비를 절감하고 각 보관실에 설치된 증발기 사이의 열전도를 이용하여 열적 효율을 향상시킬 수 있다.According to the present invention having the configuration described above, it is possible to configure only one suction pipe to reduce the material cost and improve the thermal efficiency by using the heat conduction between the evaporators installed in each storage room.

이하, 첨부된 도 3과 도 4를 참조하여 본 발명의 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIGS. 3 and 4.

도시한 바와 같이, 본 발명에 따른 냉각 사이클(100)은 복수의 보관실(200)이 형성된 김치냉장고에 설치되는 것으로서, 압축기(10), 압축기(10)에 연결된 응축기(20), 응축기(20)로부터 각 보관실(200)로 분기되어 설치된 팽창기(30)와 증발기(40)(70)를 포함한다.As shown, the cooling cycle 100 according to the present invention is installed in the kimchi refrigerator formed with a plurality of storage chamber 200, the compressor 10, the condenser 20, the condenser 20 connected to the compressor 10 It includes an expander 30 and the evaporator 40, 70 is branched from each storage chamber 200 from the installation.

특히, 본 발명에 따르면, 상기 각 증발기(40)(70)의 출구가 취합통로부(50)에서 함께 연결되어 있고, 취합통로부(50)의 출구와 압축기(10) 사이에 단일의 흡입파이프(60)가 설치되어 있다.In particular, according to the present invention, the outlets of the respective evaporators 40, 70 are connected together in the collecting passage 50, and a single suction pipe is connected between the outlet of the collecting passage 50 and the compressor 10. 60 is provided.

이에 따라, 증발기(40)(70)를 통과한 냉매가 취합통로부(50)에서 일단 모여진 후 함께 통과하고, 통과한 냉매는 흡입파이프(60)를 통해 압축기(10)로 향하게 된다.Accordingly, the refrigerant having passed through the evaporators 40 and 70 once collected together in the collecting passage part 50 and passes therethrough, and the refrigerant passing through is directed to the compressor 10 through the suction pipe 60.

이러한 구조로 인해, 흡입파이프(60)가 1개만 필요하므로 흡입파이프에 의해 소요되는 재료비가 크게 절감된다.Due to this structure, since only one suction pipe 60 is required, the material cost required by the suction pipe is greatly reduced.

특히, 각각의 증발기(40)(70) 사이의 거리가 크게 단축되기 때문에 열전도를 통해 한쪽 증발기로부터 다른 쪽 증발기로 열적 영향을 미칠 수 있게 된다.In particular, since the distance between each evaporator 40, 70 is greatly shortened, it is possible to have a thermal effect from one evaporator to the other through heat conduction.

구체적으로, 독립 냉각제어중 모든 보관실이 소정의 냉각온도에 도달하게 되면 압축기가 멈추게 되며 이 시점부터 보관실의 온도는 다시 상승하게 된다.Specifically, when all the storage chambers reach the predetermined cooling temperature during the independent cooling control, the compressor is stopped and the temperature of the storage chamber rises again from this point.

이 경우 온도가 상승하는 속도는 보관실마다 다르다. 그러나, 증발기들 사이의 거리가 매우 가깝기 때문에 열전도를 통해 온도상승속도가 빠른 보관실에 연 결된 증발기의 냉매 온도의 상승을 최대한 억제할 수 있다.In this case, the rate at which the temperature rises varies from store to store. However, since the distance between the evaporators is very close, it is possible to suppress the increase in the refrigerant temperature of the evaporator connected to the storage chamber with a rapid temperature rise rate through the heat conduction.

이에 따라, 압축기(10)의 재가동 시점을 다소 지연시킬 수 있으므로 김치냉장고의 열효율이 크게 높아지게 된다.Accordingly, since the restart time of the compressor 10 can be delayed somewhat, the thermal efficiency of the Kimchi refrigerator is greatly increased.

상기 취합통로부(50)는 코일 형태로 형성되어 공간 이용을 극대화하는 것이 좋다.The collecting passage 50 is formed in the form of a coil to maximize the use of space.

상기 취합통로부(50)의 열적 충격을 방지하기 위해 각 증발기(40)(70)의 출구 사이에 100~200mm의 중간파이프(80)를 연결하는 것이 바람직하다.In order to prevent the thermal shock of the collecting passage 50, it is preferable to connect the intermediate pipe 80 of 100 ~ 200mm between the outlet of each evaporator 40, 70.

또한, 기술되지 않은 도면부호 90은 상기 흡입파이프(60)와 압축기(10) 사이의 파이프를 연결하는 연결커넥터(90)이다.In addition, reference numeral 90 which is not described is a connecting connector 90 for connecting the pipe between the suction pipe 60 and the compressor 10.
