본 발명은 멀티에어컨용 실내기의 연결구조에 관한 것으로, 특히 실내기의 추가설치시 다른 실내기에 대해 명렬식으로 접속되는 것에 비교해서 배관길이가 단축됨은 물론, 실내기의 설치가 용이하도록 된 멀티에어컨용 실내기의 연결구조에 관한 것이다.The present invention relates to a connection structure of an indoor unit for a multi-air conditioner, and more particularly, to an indoor unit for a multi-air conditioner in which a length of a pipe is shortened as compared with a case where the indoor units are additionally connected to other indoor units, As shown in Fig.
일반적으로 실외기는, 압축기와 실외측열교환기 및 냉매관에 연결되는 밸브등으로 이루어지고, 실내기는 실내측열교환기와 모세관 또는 팽창밸브 및 외밸브등으로 이루어져 있는 바, 에어컨은 압축기에 의해 고온고압의 기체상태로 압축된 냉매가 실외측열교환기로 토출되면 실외측열교환기에서는 고온고압으로 압축된 기체냉매를 냉각팬에 의해 송풍되는 공기로 열교환하여 냉매를 강제냉각시켜 액화한다.Generally, the outdoor unit is composed of a compressor, an outdoor heat exchanger and a valve connected to the refrigerant pipe. The indoor unit is composed of an indoor heat exchanger, a capillary tube, an expansion valve and an external valve. When the refrigerant compressed in the gaseous state is discharged to the outdoor heat exchanger, in the outdoor heat exchanger, gas refrigerant compressed at high temperature and high pressure is heat-exchanged with air blown by the cooling fan to forcibly cool the refrigerant to liquefy.
이어서 상기 실외측열교환기에서 약 35℃-40℃로 온도가 저하된 고압의 액상냉매는 증발압력까지 팽창시키는 모세관을 통과하면서 저온저압의 기체와 액체로 공존하는 냉매로 되어 실내측열교환기에 유입된다.The high-pressure liquid-phase refrigerant whose temperature has dropped to about 35 ° C to 40 ° C in the outdoor heat exchanger passes through the capillary tube which expands to the evaporation pressure and flows into the indoor heat exchanger as a refrigerant coexisting with the low- .
한편 상기 실내측열교환기로 유입된 냉매는 실내측열교환기를 통과하면서 기화한 때 실내팬에 의해 송풍되는 공기에서 열을 빼앗아 실내공기를 냉각시킨 다음, 그 냉각된 공기(냉풍)를 실내로 토출해서 냉방을 행하고, 상기 실내측열교환기에서 상변환된 저온저압의 기체냉매는 다시 압축기에 의해 흡입되어 반복순환하는 냉동싸이클을 형성한다.On the other hand, the refrigerant flowing into the indoor heat exchanger takes heat from the air blown by the indoor fan when it is vaporized while passing through the indoor heat exchanger to cool the indoor air, and then discharges the cooled air (cool air) And the low-temperature and low-pressure gas refrigerant phase-transformed by the indoor heat exchanger is again sucked by the compressor to form a refrigerant cycle repeatedly circulated.
그런데 이와같은 냉동싸이클에 의해 냉방을 수행하는 공기조화기는 하나의 실외기로 하나의 실내기를 제어하여 개별냉방을 수행하기 때문에 여러방을 동시에 냉방시킬 수 없는 결점이 있음은 물론, 다수개의 실내기로 여러방을 냉방한 경우에는 다수개의 실외기를 설치해야 하므로 설치공간을 확보하기가 곤란하고 미관도 좋지 않은 결점이 있었다.However, since the air conditioner performs cooling by the refrigeration cycle, one indoor unit is controlled by one outdoor unit to perform individual cooling, so that it is not possible to simultaneously cool a plurality of rooms. In addition, A plurality of outdoor units must be installed, so that it is difficult to secure a space for installation and there is a drawback that the beauty is not good.
이러한 제반결점을 해소하기 위하여 종래에도 제 1도에 도시된 것과 같은 냉매순환을 하도록 된 멀티에어콘이 제안되어 있는 바, 실외기(A)에서 공급되는 냉매가 다수개의 냉매관을 통하여 다수개의 실내기(B,C,D)에 공급 및 순환되도록 연결되되, 상기 실내기(B,C,D)들은 각각 병렬로 연결되어 있다.In order to overcome these drawbacks, a multi-air conditioner has been proposed in which a refrigerant circulation as shown in FIG. 1 has been proposed. The refrigerant supplied from the outdoor unit A is supplied to a plurality of indoor units B C, and D, and the indoor units B, C, and D are connected in parallel.
여기서 상기 실외기(A)는, 압축기(11)에 실외측열교환기(12)가 연결되고, 이 실외측열교환기(12)에 실내기(B,C,D)와 같은 갯수로 분기시킬 수 있도록 된 분배수단인 솔레노이드밸브(14a,14b,14c)가 연결되며, 이 각각의 솔레노이드밸브(14a,14b,14c)에 2방향밸브(15a,15b,15c)가 연결됨과 더불어, 상기 압축기(11)의 다른 쪽에는 상기 실내기(B,C,D)를 통과한 냉매가 압축기(11)로 흡입되도록 안내하는 2방향밸브 (18a,18b,18c)가 설치되어 있다.The outdoor unit A is connected to an outdoor heat exchanger 12 to a compressor 11 and is connected to the outdoor heat exchanger 12 in the same number as that of the indoor units B, Directional valves 15a, 15b and 15c are connected to the respective solenoid valves 14a, 14b and 14c and the solenoid valves 14a, 14b and 14c serving as distributing means are connected to the solenoid valves 14a and 14b, Way valves 18a, 18b and 18c for guiding the refrigerant having passed through the indoor units B, C and D to be sucked into the compressor 11 are provided on the other side.
한편 실내기는, 분배수단의 솔레노이드밸브(14a,14b,14c)와 연결된 냉매관(16a,16b,16c)을 매개로 온도식팽창밸브(17a,17b,17c)가 각각 직렬연결됨과 더불어, 이 온도식팽창밸브(17a,17b,17c)와 다수개의 실내측열교환기(13a,13b,13c)가 각각 직렬로 연결된 구조로 되어 있다.On the other hand, the indoor units are connected in series with the thermostatic expansion valves 17a, 17b and 17c through the refrigerant pipes 16a, 16b and 16c connected to the solenoid valves 14a, 14b and 14c of the distributing means, A plurality of indoor expansion valves (17a, 17b, 17c) and a plurality of indoor heat exchangers (13a, 13b, 13c) are connected in series.
이러한 멀티에어컨의 냉매제어는, 압축기(11)에 의해 고온고압의 기체상태로 압축된 냉매가 1개의 실외측열교환기(12)에 유입되면 상기 실외측열교환기(12)에서는 고온고압으로 압축된 기체냉매를 냉각팬에 의해 송풍되는 공기로 냉매를 냉각시켜 액화시키게 되고, 상기 실외기 (12)에서 액화된 저온고압의 액상냉매가 실내측열교환기(13a,13b,13c)와 같은 갯수이면서 해당 실내측열교환기(13a,13b,13c)와 연동하여 개폐되는 솔레노이드밸브(14a,14b,14c)와 2방향밸브(15a,15b,15c) 및 냉매관(16a,16b,16c)을 매개로 분리됨과 동시에 냉매의 유입을 제어함은 물론 양을 조절할 수 있는 온도식팽창밸브(17a,17b,17c)를 통과하면서 상변화되어 실내측열교환기(13a,13b,13c)에 유임되며, 이 실내측열교환기(13a,13b,13c)를 통과하는 냉매가 증발하여 기화한 때 실내팬에 의해 송풍되는 공기에서 열을 빼앗아 실내공기를 냉각시킨 다음 그 냉각된 공기를 실내로 토출시켜 냉방을 행하고, 상기 실내측열교환기(13a,13b,13c)에서 상변화된 저온저압의 기체냉매는 유입수단인 2방향밸브(18a,18b,18c)를 통해서 다시 압축기(11)가 흡입하게 되어 반복순환하는 냉동싸이클을 형성한다.When the refrigerant compressed in the gas state of high temperature and high pressure by the compressor 11 flows into one outdoor heat exchanger 12, the outdoor heat exchanger 12 compresses the refrigerant at high temperature and high pressure The liquid refrigerant of low temperature and high pressure liquefied in the outdoor unit (12) is supplied to the indoor heat exchangers (13a, 13b, 13c) The solenoid valves 14a, 14b and 14c opened and closed in conjunction with the side heat exchangers 13a, 13b and 13c are separated from each other through the two-way valves 15a, 15b and 15c and the refrigerant pipes 16a, 16b and 16c, At the same time, the inflow of the refrigerant is controlled, and the refrigerant is phase-changed while being passed through the thermostatic expansion valves 17a, 17b, 17c capable of controlling the amount of refrigerant and is maintained in the indoor heat exchangers 13a, 13b, 13c. When the refrigerant passing through the units 13a, 13b, 13c evaporates and vaporizes, The low temperature low pressure gas refrigerant phase-changed in the indoor heat exchangers (13a, 13b, 13c) is introduced into the indoor heat exchangers (13a, 13b, 13c) The compressor 11 is again sucked through the two-way valves 18a, 18b and 18c to form a refrigerating cycle in which the refrigerant is repeatedly circulated.
그러나 이러한 멀티에어콘용 실내기의 연결구조는, 상기 실내기(B,C,D)들간에 명렬로 접속되어 있으므로 별도의 실내기를 추가할 때 마다 별도의 솔레노이드밸브와 2방향밸브를 추가해야함은 물론, 추가설치시 배관의 길이가 많이 소요되는 결점이 있었다.However, since the connection structure of the indoor units for multi-air conditioners is connected in series between the indoor units B, C, and D, a separate solenoid valve and two-way valve must be added every time a separate indoor unit is added. There is a drawback that the length of piping is long during installation.
이에 본 발명은 상기와 같은 결점을 해결하기 위하여 안출된 것으로, 실내기의 추가설치시에 다른 실내기로 부터 3방향밸브를 매개로 직렬로 연결되는 구조로 되어, 실내기의 추가설치시 다른 실내기에 대해 병렬로 접속되는 것과 비교해서 배관길이가 단축됨은 물론, 실내기의 설치가 용이하도록 된 멀티에어컨용 실내측열 교환기의 연결구조를 제공한에 그 목적이 있다.SUMMARY OF THE INVENTION Accordingly, the present invention has been made in order to solve the above-mentioned drawbacks, and it is an object of the present invention to provide an air conditioner in which indoor units are connected in series via three- The present invention provides a connection structure of an indoor heat exchanger for a multi-air conditioner in which a length of a piping is shortened as compared with a case where the indoor heat exchanger is connected to the indoor heat exchanger.

여기서 멀티에어컨의 실외기를 좀더 상세히 설명하면, 고온고압의 기체상태로 압축된 기체냉매를 이송시킬 수 있도록 설치된 압축기(11)와, 이 압축기(11)에 연결된 실외측열교환기(12)와, 이 실외측열교환기(12)의 출구쪽과 압축기의 흡입구쪽에 연결된 2방향밸브(15,18)등으로 이루어져 있다.Here, the outdoor unit of the multi-type air conditioner will be described in detail. The outdoor unit includes a compressor 11 installed to transfer gas refrigerant compressed to a high-temperature and high-pressure state, an outdoor heat exchanger 12 connected to the compressor 11, Way valves (15, 18) connected to the outlet side of the outdoor heat exchanger (12) and to the suction port side of the compressor, and the like.
그리고 멀티에어콘의 실내기(B,C,D,...)는, 상기 2방향밸브(15)에 냉매관 (la,lb,...)을 매개로 유임된 냉매를 제어함은 물론 통과양을 조절할 수 있도록 된 전자식팽창밸브(2a,2b}...)와, 이 전자식팽창밸브(2a,2b,...)을 매개로 연결되는 다수개의 실내측열교환기(13a,13b,...) 등으로 이루어져 있다.The indoor units B, C, D, etc. of the multi-air conditioner control the refrigerant circulated through the refrigerant pipes la, lb, ... to the two-way valve 15, And a plurality of indoor heat exchangers 13a, 13b, ... connected to each other through the electronic expansion valves 2a, 2b, ..., .) And so on.
한편 상기 전자식팽창밸브(2a,2b,2c,...)은, 냉매유로를 전폐/전개가 가능하며 실내기와 결합되어 실내기의 입출구온도차에 의한 수식값을 실내기마이컴에 입력하여 마이컴제어에 의한 냉매량을 조절시켜 감압팽창케하는 것이다.On the other hand, the electronic expansion valves 2a, 2b, 2c,...

이와 같이 구성된 본 발명의 실시예에 의한 실내기의 운전과 그에 따른 효과를 다음에 설명한다.The operation of the indoor unit according to the embodiment of the present invention thus configured and its effect will be described below.
먼저 1실운전시에는 운전하려고 하는 실내기(A,B,C,...)의 입구측 전자식팽창밸브(2a,2b,2c,...)을 열고 나머지는 닫게되면 열려있는 전자식팽창밸브(2a,2b,2c,...)에서 감압팽창된 다음 작동하려고 하는 실내측열교환기(13a,13b,13c,...)에서 증발되어 압축기(11)로 재순환된다.First, at the time of one room operation, the inlet side electronic expansion valves 2a, 2b, 2c, ... of the indoor units A, B, C, The refrigerant is evaporated in the indoor heat exchangers 13a, 13b, 13c, ... which are decompressed and expanded in the indoor units 2a, 2b, 2c, ..., and then recycled to the compressor 11.
