본 고안은 공기조화기용 냉동장치에 관한 것으로, 특히, 압축기의 토출가스 냉매를 분기시켜서 각 실외열교환기로 유도하는 냉매관의 분기부의 설치높이를 상,하 각 실외열교환기의 냉매유입구의 중간에 위치시켜 실외열교환기 전체의 열교환량의 저하를 억제할 수 있도록 된 공기조화기용 냉동장치에 관한 것이다.The present invention relates to a refrigerating device for an air conditioner, and in particular, the installation height of the branch of the refrigerant pipe branching the discharge gas refrigerant of the compressor to guide each outdoor heat exchanger is located in the middle of the refrigerant inlet of each of the upper and lower outdoor heat exchangers. The present invention relates to a refrigerating device for an air conditioner, which can suppress a decrease in the heat exchange amount of the entire outdoor heat exchanger.
종래에는 제 1,2도에서 보는 바와 같이 실내기(2)와 실외기(1)를 각각 접속시키는 냉매배관(3)(4)과 서비스밸브(5)(6)(7)(8), 실외기(1)의 밑판(32)에 설치되는 어큐뮬레이터(15)가 부착된 압축기(10)와, 병렬접속된 2개의 실외열교환기(11)(12)와 상단에 설치된 감압기(13) 및 실내 열교환기(14)를 배관접속하여 구성된 것으로, 실외열교환기(11)(12)는 상,하로 배치되어 있고, 감압기(13)에는 캐피라리튜브를 사용하며, 실외열교환기(11)(12)에는 실외열교환핀(16)과 전열관(17)을 설치하였고, 실외열교환기(14)에도 실내열교환기핀(18)을 다수 형성하였다.Conventionally, as shown in FIGS. 1 and 2, refrigerant pipes 3, 4, service valves 5, 6, 7, 8, and outdoor units, which connect the indoor unit 2 and the outdoor unit 1, respectively, The compressor 10 with the accumulator 15 attached to the bottom plate 32 of 1), the two outdoor heat exchangers 11 and 12 connected in parallel, the pressure reducer 13 installed at the top and the indoor heat exchanger The heat exchanger 11 and 12 are arranged up and down, the capillary tube is used as the pressure reducer 13, and the outdoor heat exchanger 11 and 12 is connected to the outdoor heat exchanger 11 and 12. The outdoor heat exchange fins 16 and the heat pipes 17 were installed, and a plurality of indoor heat exchanger fins 18 were also formed in the outdoor heat exchanger 14.
압축기(10) 상단에 토출가스냉매관(40)을 설치하고, 상기 토출가스냉매관(40)을 분기시켜서 상측 냉매관(43)(44)에 접속되게 분기관(41)을 형성한 것과, 하측에 냉매관(45)(46)에 접속되게 분기관(42)을 형성하였으며, 실외열교환기(11)(12)에도 각각 분기관(47)(48)을 설치 하였다.The discharge gas refrigerant pipe 40 is installed on the upper end of the compressor 10, and the branch gas 41 is formed to branch to the discharge gas refrigerant pipe 40 so as to be connected to the upper refrigerant pipes 43 and 44, Branch pipes 42 were formed at the lower side to be connected to the refrigerant pipes 45 and 46, and branch pipes 47 and 48 were also installed in the outdoor heat exchangers 11 and 12, respectively.
분기부(50)는 압축기(10)의 토출가스 냉매관(40)의 분기부이고, 분기부(51)은 분기관(41)의 분기부이며 분기부(52)는 분기관(42)이 분기부이다.The branch 50 is a branch of the discharge gas refrigerant pipe 40 of the compressor 10, the branch 51 is a branch of the branch pipe 41, and the branch 52 is a branch pipe 42. It is a branch.
이와같이 실외열교환기(11)(12)로 유입되는 냉매를 미리 분기시킨 이유는 실외열교환기(11)(12)내에서의 냉매압력손실을 적게하기 위한 것이며, 많은 냉매봉입량에 의해 냉매순환량이 많은 냉동장치에 유효하기 때문이다.The reason why the refrigerant flowing into the outdoor heat exchangers 11 and 12 is branched in advance is to reduce the refrigerant pressure loss in the outdoor heat exchangers 11 and 12. This is because it is effective for many freezers.
또한 분기관(63)은 냉매관(61)(62)에 접속되고 냉매관(64)은 서비스밸브(7)와 감압기(13)를 접속하는 것이다. 상술한 바와같은 종래의 공기조화기용 냉동장치에서는 냉방운전시에 실외열교환기(11)(12)에서 응축된 냉매가 실내열교환기(14)에서 증발된다.The branch pipe 63 is connected to the coolant pipes 61 and 62, and the coolant pipe 64 connects the service valve 7 and the pressure reducer 13. In the conventional air conditioner refrigeration apparatus as described above, the refrigerant condensed in the outdoor heat exchangers 11 and 12 during the cooling operation is evaporated in the indoor heat exchanger 14.
압축기(10)로부터 토출되어 냉매관(40)을 통해서 분기관(41)으로 흐르는 가스냉매를 냉매관(40)을 통해서 분기관(41)으로 흐르는 가스냉매보다 높이 △h(=h1-h2)만큼 윗방향으로 향하여 흐르지 않으면 안되는데 이것은 분기부(51)가 분기부(52)보다 △h(=h1-h2)만큼 높은 위치에 설치되어 있기 때문이다.The gas refrigerant discharged from the compressor 10 and flowing to the branch pipe 41 through the refrigerant pipe 40 is higher than the gas refrigerant flowing through the refrigerant pipe 40 to the branch pipe 41 Δh (= h1-h2). This must flow upward as much as the branch 51 is provided at a position higher by Δh (= h1-h2) than the branch 52.
이 때문에 압축기(10)에서 토출된 가스 냉매중 냉매관(43)(44)으로 흐르는 냉매량보다 적고, 냉매관(45)(46)으로 흐르는 냉매의 영향도 받는데 이것은 분기부(50)에서의 가스냉매온도가 88℃인 것에 대해 분기부(51)에서의 냉매온도가 84℃이고, 분기부(52)에서의 냉매온도가 86℃라는 실험결과로 확인되기 때문이다.For this reason, the amount of the refrigerant flowing into the refrigerant pipes 43 and 44 of the gas refrigerant discharged from the compressor 10 is less than that of the refrigerant flowing through the refrigerant pipes 45 and 46. This is because it is confirmed by the experimental result that the refrigerant temperature at the branch portion 51 is 84 ° C and the refrigerant temperature at the branch portion 52 is 86 ° C when the refrigerant temperature is 88 ° C.
이와같이 분기부(51)에서의 냉매온도가 분기부(52)에서의 냉매온도에 비하여 낮은것은 분기부(51)에 비하여 분기부(52)로 흘러들어가는 압축기의 토출가스 냉매량이 많기 때문이다.The reason why the coolant temperature at the branch 51 is lower than the coolant temperature at the branch 52 is because the amount of refrigerant discharged from the compressor flowing into the branch 52 is larger than that at the branch 51.
분기부(52)로 흘러들어가는 압축기의 노출가스 냉매량이 많으면 하측실의 열교환기(12)로 흘러들어가는 냉매량이 많아지게 되어 실외열교환기(11)(12) 전체의 열교환량이 떨어지는 문제점이 있는 것이다.If the amount of refrigerant gas exposed to the compressor flowing into the branch 52 increases, the amount of refrigerant flowing into the heat exchanger 12 in the lower chamber increases, resulting in a decrease in the heat exchange amount of the entire outdoor heat exchanger 11 and 12.
본 고안은 이러한 종래의 문제점을 해결하기 위하여 안출한 것으로서, 본 고안의 목적은, 냉매유로저항을 갖도록 설치하여 실외열교환기 전체의 열교환량의 저하를 제어하도록 한 것에 있는 것이다.The present invention is devised to solve such a conventional problem, and an object of the present invention is to provide a refrigerant flow resistance so as to control a decrease in the heat exchange amount of the entire outdoor heat exchanger.
본 고안의 목적을 해소하기 위하여 압축기와 상,하로 배치하되 병렬로 접속된 복수의 실외열교환기와 감압기와 실내열교환기를 배관 접속한 공기조화기용 냉동장치에 있어서, 압축기의 토출가스 냉매를 분기시켜서 각 실외 열교환기로 유도하는 냉매관의 분기부의 설치높이를 상,하로 각 실외열교환기의 냉매유입구의 중간에 위치한 것과, 하측 실외열교환기로 냉매를 유도하는 분기관에 역 U자형의 관을 설치하여 냉매의 유로저항을 갖도록 하였으며, 이때 역 U자형의 관의 설치높이(h)는 분기부의 설치높이(H)의In order to solve the object of the present invention, a plurality of outdoor heat exchanger and a pressure reducer and an indoor heat exchanger, which are arranged in parallel with the compressor and connected up and down, are connected to each other in a refrigerator for an air conditioner. The installation height of the branch of the refrigerant pipe leading to the heat exchanger is located in the middle of the refrigerant inlet of each outdoor heat exchanger, and an inverted U-shaped pipe is installed in the branch pipe that guides the refrigerant to the lower outdoor heat exchanger. In this case, the installation height (h) of the inverted U-shaped pipe is equal to the installation height (H) of the branch.
h로 하여 분기부의 위치보다 높게 설치되어 상측 실외열교환기와 하측실외열교환기로 유입되는 냉매가 한쪽으로 치우쳐 흐르는 것을 방지하고 상,하측 실외열교환기로 유입되는 냉매량이 같아짐에 따라 실외열교환기 전체의 열교환량 저하를 억제할 수 있도록 한 고안인 것이다. h It is installed higher than the position of the branch part to prevent the refrigerant flowing into the upper outdoor heat exchanger and the lower outdoor heat exchanger from flowing to one side, and the amount of refrigerant flowing into the upper and lower outdoor heat exchangers becomes equal, so that the heat exchange amount of the entire outdoor heat exchanger decreases. It is designed to be able to suppress.
이하 본 고안의 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
실외기(1)는 실내기(2)를 접속하는 냉매배관(3)(4)과, 서비스밸브(5)(6)(7)(8), 압축기(10)와 병렬접속된 2개의 실외열교환기(11)(12)와 감압기(13), 실내열교환기(14)와 어큐뮬레이터(15)를 배관접속하여 구성되고, 실외열교환기(11)(12)는 상,하로 배치되며, 감압기(13)는 캐피라리튜브를 사용하고, 실외열교환기(11)(12)에는 핀(16)과 전열관(17)을 형성하여서된 것을 종래와 동일한 구성인 것이며,The outdoor unit 1 includes two refrigerant pipes 3 and 4 for connecting the indoor unit 2, two outdoor heat exchangers connected in parallel with the service valves 5, 6, 7 and 8, and the compressor 10. (11) (12) and the pressure reducer (13), the indoor heat exchanger (14) and the accumulator (15) are connected to the pipe, the outdoor heat exchanger (11) (12) is arranged up and down, 13, the capillary tube is used, and the outdoor heat exchanger (11) (12) is formed by the fin (16) and the heat pipe (17) is the same as the conventional configuration,
압축기(10) 상부일측에 설치된 토출가스냉매관(20)과 상기 토출가스냉매관(20)을 분기시켜 냉매관(25)(26)에 접속되는 분기관(21)과, 또 분기관(22)은 토출가스냉매관(20)을 분기시켜 냉매관(27)(28)에 접속되고, 실외열교환기(11)(12)에도 각각 분기관(47)(48)을 설치하였으며, 분기관(24)에는 역 U자형의 관(23)을 형성하였다.A branch pipe 21 connected to the refrigerant pipes 25 and 26 by branching the discharge gas refrigerant pipe 20 and the discharge gas refrigerant pipe 20 provided on the upper side of the compressor 10 and the branch pipe 22. ) Branched to the discharge gas refrigerant pipe 20 and connected to the refrigerant pipes 27 and 28, and branch pipes 47 and 48 were also installed in the outdoor heat exchangers 11 and 12, respectively. 24, an inverted U-shaped tube 23 was formed.
또 분기관(63)은 각 냉매관(61)과 감압기(62)를 접속하는 것이고, 냉매관(64)은 서비스밸브(7)와 감압기(13)를 접속하는 냉매관이다.The branch pipe 63 connects each of the refrigerant pipes 61 and the pressure reducer 62, and the refrigerant pipe 64 is a refrigerant pipe connecting the service valve 7 and the pressure reducer 13.
미 설명부호 31은 실외기의 외장윗판이고,Reference numeral 31 is an exterior top plate of the outdoor unit,
32는 실외기의 외장밑판이며,32 is the exterior bottom plate of the outdoor unit,
33은 취부대이고,33 is the mount,
34는 팬모터이며,34 is a fan motor,
35는 송풍팬이다.35 is a blower fan.
이와같이 구성된 본 고안은 냉동장치에 있어서 냉방운전시 냉매는 압축기(10)에서 토출된 고온 고압가스냉매가 실외열교환기(11)(12)에서 응축하고, 실내열교환기(14)에서 증발한다.The present invention configured as described above, the refrigerant during the cooling operation in the refrigerating device, the high-temperature high-pressure gas refrigerant discharged from the compressor 10 condenses in the outdoor heat exchanger (11) (12), and evaporates in the indoor heat exchanger (14).
이때 압축기(10)로 부터 토출된 가스냉매는 냉매관(20)의 분기부(70)의 설치높이(H)로 분기관(21)으로 흐르는 냉매가 분기관(22)으로 흐르는 냉매보다 약간 흐르기가 어려우므로, 분기관(22)(24)에 역 U자형의 관(23)을 설치하였고, 이것의 설치높이(h)는At this time, the gas refrigerant discharged from the compressor 10 flows slightly from the refrigerant flowing into the branch pipe 21 at the installation height H of the branch 70 of the refrigerant pipe 20 than the refrigerant flowing through the branch pipe 22. Since it is difficult to install, an inverted U-shaped pipe 23 is installed in the branch pipes 22 and 24, and its installation height h is
h로 설계된다. h Is designed as.
따라서 분기부(70)에서의 냉매는 분기관(22)(24)으로도 흐르기가 어렵기 때문에 실외열교환기(11)(12)로 각각 유입되는 냉매량이 한쪽 열교환기로 냉매가 편중되어 흐르는 것이 억제되어지고, 상측 실외열교환기(11)와 하측 실외열교환기(12)로 흐르는 냉매량이 거의 같아짐에 따라 실외열교환기(11)(12) 전체의 열교환량의 저하를 억제할 수 있는 것이다.Therefore, since the refrigerant in the branch 70 is difficult to flow into the branch pipes 22 and 24, the amount of refrigerant flowing into the outdoor heat exchangers 11 and 12, respectively, is suppressed from flowing out of the refrigerant to one heat exchanger. As the amount of refrigerant flowing through the upper outdoor heat exchanger 11 and the lower outdoor heat exchanger 12 becomes substantially the same, the decrease in the heat exchange amount of the entire outdoor heat exchanger 11 and 12 can be suppressed.
이것은 상분기부(71)의 냉매온도가 85.3℃이고 하분기부(72)의 냉매온도가 85.5℃로 되는 실험결과로 확인되는 것이다.This is confirmed by the experimental result that the refrigerant temperature of the upper branch portion 71 is 85.3 ° C and the refrigerant temperature of the lower branch portion 72 is 85.5 ° C.
이상과 같이 본 고안은 상측 실외열교환기(11)로 유입되는 냉매는 분기부(70)의 설치 위치때문에 냉매흐름이 쉽지 않지만 분기관(22)(24)에 냉매유동저항이 크게 설정되어 있기 때문에 상측 실외열교환기(11)와 하측 실외열교환기(12)로 유입되는 냉매가 한쪽으로 치우쳐 흐르는 것을 방지할 수 있고, 실외열교환기(11)(12)로 유입되는 냉매량도 거의 같아짐에 따라 실외열교환기(11)(12)전체의 열교환량 저하를 억제할 수 있는 효과가 있는 것이다.As described above, since the refrigerant flowing into the upper outdoor heat exchanger 11 is not easily flowed due to the installation position of the branch 70, the refrigerant flow resistance is largely set in the branch pipes 22 and 24. The refrigerant flowing into the upper outdoor heat exchanger 11 and the lower outdoor heat exchanger 12 can be prevented from flowing to one side, and the amount of refrigerant flowing into the outdoor heat exchanger 11 and 12 is almost the same. It is an effect which can suppress the fall of the heat exchange amount of the whole heat exchangers 11 and 12.
이상과 같이 본 고안은 압축기와 상,하로 배치하되 병렬로 접속된 복수의 실외열교환기와 감압기와 실내열교환기와 어큐뮬레이터를 배관접속하고, 감압기에는 캐피라리튜브를 사용한 공기조화기용 냉동장치에 있어서, 압축기의 토출가스냉매관의 분기부의 위치(높이)를 상,하 각 실외열교환기의 냉매유입구의 중간에 위치시키고, 하측 실외 열교환기로 가스냉매를 유도하는 분기관에는 역 U자형관을 설치하여 냉매유로저항을 갖도록 된 것으로 간단하면서도 매우 유용한 고안인 것이다.As described above, the present invention is arranged up and down with the compressor, but a plurality of outdoor heat exchanger, a pressure reducer, an indoor heat exchanger and an accumulator connected in parallel, and the pressure reducer is an air conditioner refrigeration apparatus using a capillary tube. The position (height) of the branch of the discharge gas refrigerant pipe of the discharge gas is placed in the middle of the refrigerant inlet of each of the upper and lower outdoor heat exchangers, and an inverted U-shaped pipe is installed in the branch pipe to guide the gas refrigerant to the lower outdoor heat exchanger. It is designed to have resistance, but it is a simple and very useful design.
