Abstract

본 발명의 목적은 압축기로부터 실외 열교환기로 유입되는 다수의 냉매관을 하나의 냉매관과 나머지 다수의 냉매관으로 분리하여 다수의 냉매관 입구에는 전자밸브를 그리고, 또 실외 열교환기의 배출구 즉, 상기 다수의 냉매관이 하나의 냉매관과 연결되는 부위에는 역류방지밸브를 설치함으로서 달성할 수 있는데, 멀티 에어컨의 1실운전시 상기 압축기에서 압축된 냉매는 상기 실외 열교환기로 연결된 다수의 냉매관으로는 통과하지 못하고 오직 전자밸브가 설치되지 아니한 하나의 냉매관만을 통하여 이동하게 되며 또 이렇게 하여 실외 열교환기를 경유하여 응축된 냉매 역시 상기 역류방지밸브 때문에 곧 바로 모세관과 전자밸브를 통해 가동 1실 실내교환기쪽으로만 유입되기 때문에 사이클 전체의 압력도 떨어지지 않고 또 가동1실 실내교환기에 더많은 냉매가 유입되어 가동1실의 냉방효과를 더욱 높일 수 있다.An object of the present invention is to separate the plurality of refrigerant pipes flowing from the compressor to the outdoor heat exchanger into one refrigerant pipe and the remaining refrigerant pipes, and to draw the solenoid valves at the inlet of the plurality of refrigerant pipes, that is, the outlet of the outdoor heat exchanger, This can be achieved by installing a non-return valve at a portion where a plurality of refrigerant pipes are connected to one refrigerant pipe. In one operation of a multi-air conditioner, the refrigerant compressed by the compressor may be a plurality of refrigerant pipes connected to the outdoor heat exchanger. It passes through only one refrigerant pipe that does not pass and only the solenoid valve is not installed. In this way, the refrigerant condensed through the outdoor heat exchanger also moves directly through the capillary tube and the solenoid valve to the indoor exchanger because of the non-return valve. Only flows in, so the pressure of the entire cycle does not drop, The more the refrigerant flows can further enhance the cooling effect of the movable chamber 1.

본 발명은 멀티에어컨의 1실 운전시 냉방능력의 향상구조에 관한 것으로 특히 멀티 에어컨의 냉방구조에 있어서 1실만을 운전할 때에도 전체 사이클내 압력을 일정수준으로 유지케 하고 또 가동되는 1실에 냉매 유입이 많이 되도록 하여 가동되는 1실의 냉방능력이 감소되지 않도록 한 멀티 에어컨의 1실 운전시의 냉방능력 향상구조에 관한 것이다.The present invention relates to a structure for improving the cooling capacity when operating a single room of a multi-air conditioner. In particular, in the cooling structure of a multi-air conditioner, even when only one room is operated, the pressure in the entire cycle is maintained at a constant level, and refrigerant is introduced into a room that is operated. The cooling capacity improvement structure at the time of operation | operation of one room of a multi air conditioner so that the cooling capacity of the one room which operates so that it may become large is related.

제1도는 종래의 멀티에어컨의 구조도 이다. 종래 기술의 멀티에어컨 구조(이를테면 3실의 실내 열교환기)는 제1도에 도시된 바와 같이 우선 실외 열교환기(2)로부터의 나온 3개의 냉매관이 합쳐졌다가 다시 3실 실내 열교환기(1)와 연결되기 위해 3개의 냉매관으로 분리되면서 각기 해당 실내 열교환기에 관계하는 3개의 모세관(6)과 3개의 전자밸브(10)를 경유하여 실내 열교환기(1)로 연결되어져 있으며 3실 실내 열교환기(1)로 부터 나온 냉매관은 다시 합쳐져서 압축기(5)와 연결되어 있고 이 압축기(5)로부터의 토출냉매관은 다시 3개의 냉매관으로 나뉘어져 실외 열교환기(2)내 해당 3개의 회로에 각기 연결되어져서 있다. 또 실외 열교환기(2)에서 빠져나온 3개의 냉매관이 합쳐진 지점과 3실의 실내 열교환기(1)로 연결되기 위해 분리되는 지점 사이의 적당한 곳 그리고 3실의 실내 열교환기(1)에서 빠져나온 냉매관이 하나로 합쳐진 지점부터 압축기의 입구사이의 적당한 지점, 이 두 곳 사이에는 바이패스냉매관(9)이 설치되어 있는데 이 바이패스 냉매관에는 전자밸브와 바이패스 모세관(8)을 구비하고 있다.1 is a structural diagram of a conventional multi-air conditioner. In the prior art multi-air conditioner structure (such as three-room indoor heat exchanger), as shown in FIG. 1, three refrigerant pipes from the outdoor heat exchanger 2 are first merged, and then the three-room indoor heat exchanger 1 3 refrigerant pipes are separated into three refrigerant pipes, and each is connected to an indoor heat exchanger (1) via three capillary tubes (6) and three solenoid valves (10) associated with the corresponding indoor heat exchanger. Refrigerant tubes from the unit (1) are combined again and connected to the compressor (5), and the discharge refrigerant tubes from the compressor (5) are further divided into three refrigerant tubes and connected to the corresponding three circuits in the outdoor heat exchanger (2). Each is connected. In addition, a suitable place between the point where the three refrigerant pipes coming out of the outdoor heat exchanger (2) are combined and the point where it is separated to be connected to the three indoor heat exchangers (1) and the three indoor heat exchangers (1) The bypass refrigerant pipe (9) is installed between the two points where the refrigerant pipes come together and the proper point between the inlet of the compressor. The bypass refrigerant pipe is provided with a solenoid valve and a bypass capillary tube (8). have.

이같은 구조의 냉매순환 사이클 내에 냉매는 압축기(5)에서 압축되어 실외 열교환기(2)에서 응축되고 다시 모세관(6)과 전자밸브(10)를 경유하여 실내 열교환기(1)에서 증발하는 일련의 과정을 반복하면서 가동하는 공조장소내의 냉방효과를 얻을 수 있게 한다.In the refrigerant circulation cycle of this structure, the refrigerant is compressed in the compressor (5), condensed in the outdoor heat exchanger (2) and again evaporated in the indoor heat exchanger (1) via the capillary tube (6) and the solenoid valve (10). Repeat the process to achieve the cooling effect in the air conditioning station.

한편, 위와같은 종래기술의 멀티 에어컨 냉방 구조는 실내 열교환기와 실외 열교환기의 용량이 동일하게 설계되어 있는 바, 이 구조에서 단지 1실만을 가동하게 되면 실내 열교환기(1)와 실외 열교환기(2)간의 용량차이가 현저하게 달라지게 됨으로서 실외 열교환기(2)내에 응축된 냉매가 고이게 되고, 또 사이클내 전체 압력도 3실이나 2실의 운전시보다도 현저하게 떨어져 가동하는 운전 1실의 냉방능력은 현저하게 감소하게 된다.Meanwhile, the conventional air conditioner cooling structure of the above-described multi-air conditioner is designed to have the same capacity of the indoor heat exchanger and the outdoor heat exchanger. When only one room is operated in this structure, the indoor heat exchanger 1 and the outdoor heat exchanger 2 As the difference in capacity between the two is significantly changed, the refrigerant condensed in the outdoor heat exchanger 2 becomes high, and the cooling capacity of one operation room that operates significantly lower than the total pressure in the cycle than in the operation of three or two rooms. Will be significantly reduced.

본 발명은 위와 같은 종래 기술의 문제점을 해결하기 위하여 발명된 것으로 그 구체적 실시예를 첨부된 도면에 의거하여 좀 더 구체적으로 살펴보면 다음과 같다.The present invention has been invented to solve the problems of the prior art as described above in more detail on the basis of the accompanying drawings as follows.

본 발명은 제2도에 도시된 바와 같이 종래의 멀티 에어컨의 구조에 구비되어 있던 전자밸브와 바이패스모세관(8)을 구비한 바이패스 냉매관(9)을 제거하는 한편, 압축기(5)와 실외 열교환기(2)의 사이의 분리된 3개의 냉매관중 2개의 냉매관을 통하는 입구에는 전자밸브(10)를 설치하고 또 실외 열교환기(2)의 배출구의 일정부위 즉, 상기 2개의 냉매관이 나머지 하나의 냉매관과 연결되는 부위에는 역류방지밸브(11)를 설치한 것이다.The present invention removes the bypass refrigerant pipe (9) having the solenoid valve and the bypass capillary tube (8) provided in the structure of the conventional multi-air conditioner as shown in FIG. The solenoid valve 10 is installed at the inlet through the two refrigerant pipes among the three refrigerant pipes separated between the outdoor heat exchanger 2, and a predetermined portion of the outlet of the outdoor heat exchanger 2, that is, the two refrigerant pipes is provided. The reverse flow prevention valve 11 is installed at a portion connected to the other refrigerant pipe.

이같은 구성을 가진 본 발명에서 1실만을 운전할 때는 압축기(5)를 거친 압축된 냉매가 실외 열교환기(2)로 진입하게 될 때 전자밸브(10)가 설치된 2개의 냉매관의 입구인 ⓐ통로로는 이동할 수 없으며 오직 전자밸브(10)가 설치되어 있는 아니한 나머지 하나의 냉매관인 ⓑ통로로만 이동하게 되고 또 이 ⓑ통로를 통하여 실외 열교환기(2)로 유입되어 응축된 냉매는 실외 열교환기(2)를 빠져나온 뒤에도 역류방지밸브 때문에 다른 통로로 유입됨이 없이, 곧 바로 가동 1실의 실내교환기(1)와 연결된 모세관(6)과 전자밸브(10)를 경유, 실내 열교환기(1)로 유입하게 되므로 사이클내 전체 압력은 일정 수준을 유지하게 되고 또 실내 열교환기(1)로 냉매유입이 많아져 가동되는 1실의 냉방능력이 한층 높아지게 된다.In the present invention having such a configuration, when operating only one chamber, when the compressed refrigerant passing through the compressor (5) enters the outdoor heat exchanger (2), a passageway ⓐ is an inlet of two refrigerant pipes in which the solenoid valve 10 is installed. Is not moved, and the solenoid valve 10 is moved to only one passage line ⓑ, which is the remaining refrigerant tube, and the refrigerant condensed by entering the outdoor heat exchanger 2 through the passage ⓑ is an outdoor heat exchanger (2). After exiting the valve), the capillary tube (6) and the solenoid valve (10) connected to the indoor exchanger (1) of the first chamber are immediately connected to the indoor heat exchanger (1) without being introduced into another passage due to the non-return valve. Since the total pressure in the cycle is maintained at a certain level, and the refrigerant flows into the indoor heat exchanger 1, the cooling capacity of one chamber that is operated is further increased.

본 발명을 이용하면 멀티 에어컨냉방구조에서 단지 1실운전시에도 전체 공조장소를 가동할 때와 같은 냉방능력효과를 얻을 수 있게 된다.By using the present invention, it is possible to obtain the same cooling capacity effect as when operating the entire air conditioning place even in only one room operation in the multi-air conditioner cooling structure.
