It relates to a multi-type air conditioner.
일반적으로, 공기조화기는 보통 소형이고 실내기와 실외기가 일체로 형성된 일체형과 실내기와 실외기가 분리된 분리형으로 구분할 수 있는데, 특히 분리형의 경우에는 용량이 큰 실외기를 설치하고 복수개의 실내에 각각의 실내기를 설치하여 각각의 실내를 냉난방할 수 있는 멀티형으로 구성할 수 있다.In general, an air conditioner can be divided into a compact unit which is usually small and an indoor unit and an outdoor unit integrally, and a separate type that separates the indoor unit and the outdoor unit. It can be installed in a multi-type that can heat and cool each room by installing.
참조된 도면, 도 1은 종래기술에 의한 멀티형 공기조화기의 개략적인 구성도이다.1 is a schematic configuration diagram of a multi-type air conditioner according to the prior art.
종래의 멀티형 공기조화기는 도 1에 도시된 바와 같이 실외에 설치되어 냉방운전시에는 응축기로 난방운전시에는 증발기로 동작하는 실외 열 교환기(1)와, 상기 실외 열 교환기(1)와 실외공기와의 열 교환을 위하여 설치된 실외 팬(1a)과, 복수개의 실내에 각각 설치되어 냉방운전시에는 증발기로 난방운전시에는 응축기로 동작하는 복수개의 실내 열 교환기(2, 2a, 2b)와, 상기 실내 열 교환기(2, 2a, 2b)와 실내공기와의 열 교환을 위하여 설치된 실내 팬(3, 3a, 3b)과, 증발기로 동작하는 열 교환기로부터 저온저압의 냉매를 흡입하여 고온고압으로 압축하여 토출하는 압축기(5, 5a)와, 냉방운전시에는 상기 압축기(5, 5a)에서 토출되는 고온고압의 냉매가 상기 실외 열 교환기(1)로 난방운전시에는 상기 실내 열 교환기(2, 2a, 2b)로 이동되도록 절환되는 사방밸브(6, 6a)와, 상기 실외 열 교환기(1)와 상기 실내 열 교환기(2, 2a, 2b) 사이에 설치되어 이동되는 냉매가 용이하게 증발되도록 팽창시키는 팽창밸브(4, 4a)로 구성된다.The conventional multi-type air conditioner is installed in the outdoor as shown in Figure 1, the outdoor heat exchanger (1) and the outdoor heat exchanger (1) and the outdoor air to operate as a condenser during the heating operation and the evaporator during the cooling operation An outdoor fan 1a installed for heat exchange, a plurality of indoor heat exchangers 2, 2a, and 2b respectively installed in a plurality of rooms and operating as an evaporator during a cooling operation and a condenser during a heating operation; The low temperature and low pressure refrigerants are sucked from the heat exchangers 2, 2a and 2b and the indoor fans 3, 3a and 3b installed for heat exchange with the indoor air, and are compressed and discharged at high temperature and high pressure. Compressors 5 and 5a and the high temperature and high pressure refrigerant discharged from the compressors 5 and 5a during the cooling operation are carried out to the outdoor heat exchanger 1 when the indoor heat exchangers 2, 2a and 2b are used. Four-way valves (6, 6a) switched to move , It consists of an expansion valve (4, 4a) to the outdoor heat exchanger 1 and the indoor heat exchanger expansion so that the refrigerant is moved is provided between the (2, 2a, 2b) easily evaporates.
상기에서, 냉방운전사에는 상기 사방밸브(6, 6a)가 절환되어 상기 압축기(5, 5a)에서 압축된 냉매가 상기 실외 열 교환기(1)로 이동되고, 상기 팽창밸브(4, 4a)를 통과하여 상기 실내 열 교환기(2, 2a, 2b)로 이동하게 된다. 따라서, 실내로는 차가운 공기를 실외로는 뜨거운 공기를 공급하게 된다. 그리고, 난방운전시에는 상기 사방밸브(6, 6a)가 절환되어 상기 압축기(5, 5a)에서 압축된 냉매가 상기 실내 열 교환기(2, 2a, 2b)로 이동되고, 상기 팽창밸브(4, 4a)를 통과하여 상기 실외 열 교환기(1)로 이동하게 된다. 따라서, 냉난방운전에 따라 실내로는 뜨거운 공기를 실외로는 차가운 공기를 공급하게 된다.In the above, the four-way valve (6, 6a) is switched to the cooling driver, the refrigerant compressed by the compressor (5, 5a) is moved to the outdoor heat exchanger (1), and passes through the expansion valve (4, 4a) To the indoor heat exchanger (2, 2a, 2b). Therefore, the indoor air supplies cold air and outdoor hot air. In the heating operation, the four-way valves 6 and 6a are switched so that the refrigerant compressed by the compressors 5 and 5a is moved to the indoor heat exchangers 2, 2a and 2b, and the expansion valve 4, Passing through 4a) to the outdoor heat exchanger (1). Therefore, hot air is supplied indoors and cold air is supplied outdoors according to the cooling and heating operation.
이때, 만약 사용자가 제 3실이 비어 있어 냉난방을 할 필요가 없는 경우에는 제 3실의 실내 열 교환기(2b)에 냉매가 유입되지 않도록 제 3실의 서비스 밸브(7a)를 잠그면 된다. 즉, 상기 제 3실 서비스 밸브(7a)가 폐쇄되면 냉방운전의 경우에는 상기 압축기(5a)에 토출된 냉매가 상기 실외 열 교환기(1) 및 상기 팽창밸브(4a)를 통과한 다음, 제 2실의 실내 열 교환기(2a)만을 거쳐 상기 압축기(5a)로 되돌아오게 되기 때문에 상기 제 3실의 실내 열 교환기(2b)에는 냉매가 공급되지 않게 되어 제 3실의 냉방은 이루어지지 않게 된다. 물론, 난방운전의 경우에도 상기 제 3실의 서비스 밸브(7a)가 폐쇄되어 있으므로 제 3실의 난방은 이루어지지 않는다.In this case, if the user does not need to heat and cool the third chamber, the user may lock the service valve 7a of the third chamber so that refrigerant does not flow into the indoor heat exchanger 2b of the third chamber. That is, when the third chamber service valve 7a is closed, in the case of the cooling operation, the refrigerant discharged to the compressor 5a passes through the outdoor heat exchanger 1 and the expansion valve 4a, and then the second Since only the indoor heat exchanger 2a of the chamber is returned to the compressor 5a, the refrigerant is not supplied to the indoor heat exchanger 2b of the third chamber and cooling of the third chamber is not achieved. Of course, even in the heating operation, since the service valve 7a of the third chamber is closed, the third chamber is not heated.
그리고, 만약 사용자가 제 2실이 비어 있어 그 곳의 냉난방을 할 필요가 없는 경우에는 제 2실의 실내 열 교환기(2a)를 냉매가 통과하지 않도록 제 2실의 서비스 밸브(7b)를 잠그면 제 2실의 실내 열 교환기(2a)는 동작하지 않게 되므로 제 2실의 냉난방이 이루어지지 않게 된다.If the user does not need to heat and cool the room because the second room is empty, the user may lock the service valve 7b of the second room so that the refrigerant does not pass through the indoor heat exchanger 2a of the second room. Since the indoor heat exchanger 2a of the two rooms is not operated, the heating and cooling of the second room is not performed.
그러나, 종래의 멀티형 공기조화기는 어느 실내의 냉난방을 하지 않기 위해 그 실내의 서비스 밸브를 잠그는 경우에는 상기 팽창밸브(4a)를 통과하여 흐르는 냉매의 양은 변동이 없기 때문에 냉매가 통과되는 실내 열 교환기에는 평상시보다 더욱 많은 양의 냉매가 흐르게 되고, 그에 따라 개방되어 있는 서비스 밸브를 통과하는 냉매의 유속이 증대되어 소음이 발생되는 문제점이 있다.However, in the conventional multi-type air conditioner, when the service valve of the room is locked in order not to heat or cool a room, the amount of the refrigerant flowing through the expansion valve 4a is not changed. More refrigerant than usual flows, thereby increasing the flow rate of the refrigerant passing through the open service valve has a problem that the noise is generated.
본 발명은 상기한 종래 기술의 문제점을 해결하기 위하여 안출된 것으로서, 각각의 실내 열 교환기를 연결하는 바이패스관과 각각의 실내 팬의 구동여부를 제어하는 제어부를 구비하여 냉매관에서 발생되는 소음을 제어할 수 있는 멀티형 공기조화기를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, comprising a bypass pipe for connecting each indoor heat exchanger and a control unit for controlling the operation of each indoor fan to control the noise generated in the refrigerant pipe The object is to provide a multi-type air conditioner that can be controlled.

본 발명에 의한 멀티형 공기조화기는 도 2에 도시된 바와 같이 냉방운전에서는 응축기로 난방운전에서는 증발기로 동작하는 실외 열 교환기(51)와, 상기 실외 열 교환기(51)와 실외공기와의 열 교환을 위하여 설치된 실외 팬(51a)과, 각각의 실내에 설치되어 냉방운전시에는 증발기로 난방운전시에는 응축기로 동작하는 복수개의 실내 열 교환기(52, 52a, 52b)와, 상기 실내 열 교환기(52, 52a, 52b)와 실내공기와의 열 교환을 위하여 설치된 실내 팬(53, 53a, 53b)과, 상기 실외 열 교환기(51)와 상기 실내 열 교환기(52, 52a, 52b) 사이에 설치된 팽창밸브(54, 54a)와, 증발기로 동작하는 열 교환기로부터 저온저압의 냉매를 흡입하여 고온고압의 냉매로 압축시키는 압축기(55, 55a)와, 각각의 상기 실내 열 교환기(52a, 52b)와 상기 팽창밸브(54a) 사이에 설치된 서비스 밸브(57a, 57b)로 구성된다.As shown in FIG. 2, the multi-type air conditioner according to the present invention performs an heat exchange between an outdoor heat exchanger 51 which operates as a condenser in a cooling operation and an evaporator in a heating operation, and the outdoor heat exchanger 51 and outdoor air. The outdoor fan 51a is installed in each room, and a plurality of indoor heat exchangers 52, 52a, 52b installed in each room and operating as a condenser during the heating operation during the cooling operation and the indoor heat exchanger 52, 52a and 52b and indoor fans 53, 53a and 53b installed for heat exchange between indoor air and an expansion valve installed between the outdoor heat exchanger 51 and the indoor heat exchangers 52, 52a and 52b. 54, 54a, compressors 55, 55a for sucking low-temperature low-pressure refrigerant from a heat exchanger operating as an evaporator and compressing the low-temperature low-pressure refrigerant to high-temperature high-pressure refrigerant, and each of the indoor heat exchangers 52a, 52b and the expansion valve. With service valves 57a and 57b installed between 54a It is composed.
그리고, 각각의 상기 실내 열 교환기(52a, 52b)의 냉매관 사이에 설치된 바이패스관(60)과, 상기 실내 팬(53a, 53b)에 연결되어 상기 실내 팬(53a, 53b)의 구동여부를 제어하는 제어부(70)가 설치되어 있다.In addition, the bypass pipe 60 installed between the refrigerant pipes of the indoor heat exchangers 52a and 52b and the indoor fans 53a and 53b are connected to drive the indoor fans 53a and 53b. The control part 70 to control is provided.
상기와 같이 구성된 본 발명에 의한 멀티형 공기조화기의 동작을 상세하게 설명하면 다음과 같다.Referring to the operation of the multi-type air conditioner according to the present invention configured as described above in detail.
우선, 본 발명에 의한 멀티형 공기조화기는 종래와 마찬가지로 냉방운전시에는 각각의 실내에 설치된 상기 실내 열 교환기(52, 52a, 52b)가 증발기로 동작하여 각각의 실내온도를 저하시키게 되고, 난방운전시에는 각각의 상기 실내 열 교환기가 응축기로 동작하여 각각의 실내온도를 상승시키게 된다.First, the multi-type air conditioner according to the present invention, as in the conventional cooling operation, the indoor heat exchangers 52, 52a, and 52b installed in each room operate as an evaporator to lower respective indoor temperatures, and during heating operation. Each indoor heat exchanger acts as a condenser to raise the respective indoor temperature.
여기서, 어느 한 실내인 C실의 냉난방을 할 필요가 없는 경우에는 상기 C설로 연결된 냉매관이 폐쇄되도록 사용자는 상기 서비스 밸브(57a)를 잠그게 되는데, 이때 냉난방운전의 경우 모두 상기 바이패스관(60)을 통하여 냉매가 상기 C실의 실내 열 교환기(52b)로도 이동하게 되고, 그와 동시에 상기 제어부(70)가 상기 C실로 연결된 상기 서비스 밸브(57a)가 폐쇄된 것을 감지하고, 상기 C실의 실내 팬(53b)의 구동을 정지시킨다.In this case, when there is no need to air-cool the room C, which is a room, the user locks the service valve 57a so that the refrigerant pipe connected to the C snow is closed. Through 60, the refrigerant is also moved to the indoor heat exchanger 52b of the chamber C. At the same time, the control unit 70 detects that the service valve 57a connected to the chamber C is closed. Drive of the indoor fan 53b is stopped.
따라서, 상기 C실의 실내 열 교환기에는 냉매가 흐르게 되지만, 상기 C실의 실내 팬(53b)이 동작하지 않게 되므로 상기 C실의 실내공기와의 열 교환이 제대로 이루어지지 않아 전체 시스템의 효율에는 거의 영향을 미치지 않는다. 또한, 상기 실내 열 교환기(52a, 52b)로 흐르는 냉매가 상기 서비스 밸브(57a, 57b) 중의 어느 한 밸브를 폐쇄시키더라도 상기 바이패스관(60)에 의해 냉매가 원활하게 흐르게 되기 때문에 그 유속이 증가하지는 않게 된다. 따라서, 어느 하나의 상기 서비스 밸브(57a, 57b)를 잠그더라도 냉매의 유속증가가 없으므로 냉매의 유속증대에 의한 소음은 방지된다.Therefore, the refrigerant flows to the indoor heat exchanger of the chamber C, but since the indoor fan 53b of the chamber C does not operate, the heat exchange with the indoor air of the chamber C is not properly performed, and thus the efficiency of the entire system is almost impossible. Does not affect In addition, even if the refrigerant flowing to the indoor heat exchangers 52a and 52b closes any one of the service valves 57a and 57b, the refrigerant flows smoothly through the bypass pipe 60 so that the flow rate is high. It will not increase. Therefore, even if one of the service valves 57a and 57b is locked, there is no increase in the flow rate of the refrigerant, and thus noise caused by the increase in the flow rate of the refrigerant is prevented.
이와 같이, 본 발명에 의한 멀티형 공기조화기는 어느 한 실내의 냉난방을 하지 않기 위하여 상기 서비스 밸브(57a, 57b)를 잠그는 경우에도 냉매관을 따라 흐르는 냉매의 유속은 거의 변함이 없기 때문에 유속증대에 의한 소음증대를 방지하는 효과를 제공한다.As described above, the multi-type air conditioner according to the present invention has almost no change in the flow rate of the refrigerant flowing along the refrigerant pipe even when the service valves 57a and 57b are locked so as not to heat or cool the room. Provides the effect of preventing noise increase.
