본 발명은 유니터리 에어콘에 관한 것으로, 특히 한 개의 실외기에 여러 대의 실내기를 연결할 수 있도록 그 중간에 분배기를 구비한 유니터리 에어콘의 다중 분배 장치에 관한 것이다.The present invention relates to a unitary air conditioner, and more particularly, to a multi-distribution apparatus of unitary air conditioner having a distributor in the middle so as to connect several indoor units to one outdoor unit.

일반적으로 유니터리 에어콘(Unitary Air condition System)은 공장, 사무실, 호텔, 가정 등의 지하실에 구비하는 냉난방 기구를 이용하여 한 곳에서 냉풍 또는 온풍을 만들고, 이를 건물내 벽체 등에 구비한 덕트(duct)를 통해 개별 공간으로 이송하여 공급하는 중앙집중식 냉난방 시스템의 일종이다.In general, a unitary air condition system (Unitary Air Condition System) is used to create a cold or hot air in one place by using the air-conditioning equipment provided in the basement of factories, offices, hotels, homes, etc. It is a kind of centralized heating and cooling system that transfers and supplies to individual spaces through.

유니터리 에어콘은 냉난방이 필요한 영역과 필요하지 않은 영역을 구분하여 개별 영역마다 냉풍 또는 온풍을 독립적으로 공급할 수 있도록 대개 덕트의 중간에 영역제어기(zone controller)를 설치하거나, 또는 영역의 개수에 따라 복수 개의 냉난방 기구를 독립적으로 설치하고 있다.Unitary air conditioners usually have a zone controller in the middle of the duct so that they can independently supply cold or warm air to individual areas by separating the areas that need air conditioning and heating. Air conditioning equipment is installed independently.

도 1은 종래 독립형 유니터리 에어콘의 일례를 보인 모식도이다.1 is a schematic diagram showing an example of a conventional stand-alone unit air conditioner.

이에 도시한 바와 같이 종래 유니터리 에어콘은, 건물(도면에선 2층 주택)의 외부에 고정 설치하고 그 내부에 각각 실외측 열교환기를 구비하는 복수 개의 독립 실외기(11)(12)와, 각 독립 실외기(11)(12)의 실외측 열교환기와 각각 냉매관(21a)(22a)으로 직렬 연결하여 상기한 건물내 층별 특정 위치에 고정 설치하고 그 내부에 각각 실내측 열교환기를 구비하는 복수 개의 덕트형 실내기(21)(22)와, 각 덕트형 실내기(21)(22)에서 만들어지는 냉풍 또는 온풍을 건물의 내부로 공급하도록 상기 덕트형 실내기(21)(22)의 급기구와 배기구에 각각 연결하여 상기한 건물의 각 층 벽채와 천장에 각각 분리 매설하는 복수 개의 급기덕트(31)(32) 및 배기덕트(41)(42)와, 각 덕트형 실내기(21)(22)에 전기적으로 연결되도록 건물내 각 영역에 설치하여 해당 영역의 실온을 검출하고 이를 토대로 해당 실외기(11)(12)의 구동 여부를 제어하는 복수 개의 온도제어기(51)(52)를 포함하고 있다.As shown in the drawing, a conventional unitary air conditioner includes a plurality of independent outdoor units 11 and 12 fixedly installed outside a building (two-story house in the drawing) and each having an outdoor heat exchanger therein, and each independent outdoor unit. (11) (12) A plurality of duct-type indoor units having a heat exchanger in the building and fixedly installed at a specific position for each floor in the building as described above, respectively connected in series by the refrigerant pipes (21a) and (22a), respectively. (21) (22), and the cold air or hot air produced by each of the duct type indoor units (21, 22) are connected to the air supply and exhaust ports of the duct type indoor units (21, 22) to supply the interior of the building, respectively. In order to be electrically connected to the plurality of air supply ducts 31, 32 and exhaust ducts 41, 42 which are separately embedded in the wall and ceiling of each floor of the building, and each duct-type indoor unit 21, 22. Installed in each area of the building to detect the room temperature Based on and includes a plurality of temperature controllers 51 and 52 for controlling whether the driving of the outdoor units 11 and 12.

또, 급기덕트(31)(32)와 배기덕트(41)(42)를 매설할 수 없는 공간에는 독립적으로 공기를 조화시킬 수 있도록 창문형 에어콘(60)과 같은 별도의 냉온풍기를 설치하고 있다.In addition, in the space where the air supply ducts 31 and 32 and the exhaust ducts 41 and 42 cannot be embedded, a separate cold / hot air fan such as a window air conditioner 60 is provided so that the air can be independently matched.

상기와 같은 종래 독립형 유니터리 에어콘은, 예컨대 2층 주택의 경우 각 덕트형 실내기(21)(22)의 온도제어기(51)(52)에서 각 층의 부하를 검출하고, 그 부하가 해당 온도제어기(51)(52)에 이미 설정되어 있는 설정값 이상이면 해당 실외기(11)(12)에 구비한 압축기를 구동시켜 냉풍이나 온풍을 발생하며, 이 냉풍이나 온풍은 해당 층의 급기덕트(31)(32)를 통해 해당 층 전체에 고르게 공급한다.In the conventional stand-alone unit air conditioner as described above, for example, in the case of a two-story house, the temperature controllers 51 and 52 of the respective duct-type indoor units 21 and 22 detect the load of each floor, and the load is the temperature controller. If it is equal to or larger than the preset value set in (51) (52), the compressor provided in the outdoor unit (11) (12) is driven to generate cold air or hot air, and the cold air or hot air is supplied to the air supply duct (31) of the floor. Feed through the 32 evenly throughout the layer.

이때, 모든 층의 부하가 설정값 이상이면 모든 독립 실외기(11)(12)의 압축기가 구동하여 모든 층에 냉풍이나 온풍을 공급하는 반면 어느 한 층만 부하가 설정값 이상이면 그 층과 연결된 각 독립 실외기(11)(12)의 압축기만 구동하여 냉풍이나 온풍을 발생 공급하는 것이었다.At this time, if the load of all the floors is higher than the set value, the compressors of all the independent outdoor units 11 and 12 are driven to supply cold or warm air to all the floors. Only the compressors of the outdoor units 11 and 12 were driven to generate and supply cold air or warm air.

그러나, 상기와 같은 종래 유니터리 에어콘에 있어서는, 전술한 바와 같이 실내 각 영역에서의 온도편차를 감안하여 복수 개의 독립 실외기(11)(12)를 구비하여야 하므로 비용이 과다하게 되는 문제점이 있었다.However, in the conventional unity air conditioner as described above, as described above, a plurality of independent outdoor units 11 and 12 should be provided in consideration of the temperature deviation in each indoor area, resulting in excessive cost.

또, 덕트가 없는 공간에는 창문형 에어콘(60)과 같은 일체형 에어콘을 구비하여야 하므로 역시 비용이 과다하게 되는 문제점이 있었다.In addition, the space without the duct should be provided with an integrated air conditioner, such as a window type air conditioner (60), there was also a problem that the cost is excessive.

본 발명은 상기와 같은 종래 유니터리 에어콘의 열교환기가 가지는 문제점을 감안하여 안출한 것으로, 한 개의 실외기로 여러 영역을 동시에 공기조화시켜 비용을 절감할 수 있는 유니터리 에어콘의 다중 분배 장치를 제공하려는데 그 목적이 있다.The present invention has been made in view of the problems of the heat exchanger of the conventional unity air conditioner as described above, to provide a multi-distribution device of unity air conditioner that can reduce the cost by air-conditioning several areas at the same time to one outdoor unit There is a purpose.

It is preferable to install in the middle of the refrigerant pipes 121a, 122a, 170a which are piped from the side and connected to the inlet side of each indoor side heat exchanger.

상기와 같은 본 발명 유니터리 에어콘의 다중 분배 장치는 다음과 같은 작용 효과를 갖는다.The multiple distribution device of the unitary air conditioner of the present invention as described above has the following effects.

예컨대, 2층 주택의 경우 각 덕트형 실내기(121)(122)의 온도제어기(151)(152)와 분리형 실내기(170)의 온도센서(미도시)에서 현재 각 영역의 실온을 검출하여 각각에 설정값과 비교한 후 실온이 설정값을 초과하면, 이 신호를 받은 냉매분배기(160)의 제어부(161)에서는 해당 영역의 부하를 해소할 필요가 있다고 판단하여 신호선을 통해 압축기를 구동시킴과 아울러 다른 신호선을 통해 해당 실내측 열교환기와 연결된 유량제어밸브(162a,162b,162c)를 열어 실외측 열교환기를 통과하는 냉매가 해당 실내측 열교환기로 유입되도록 함으로써 해당 영역의 부하를 제거하도록 하는 것이다.For example, in the case of a two-story house, the temperature controllers 151 and 152 of the respective duct type indoor units 121 and 122 and the temperature sensors (not shown) of the separate indoor unit 170 detect the current room temperature of each area. After the comparison with the set value, if the room temperature exceeds the set value, the control unit 161 of the refrigerant distributor 160 having received the signal determines that it is necessary to release the load in the corresponding area, and drives the compressor through the signal line. By opening the flow control valves (162a, 162b, 162c) connected to the indoor heat exchanger through another signal line, the refrigerant passing through the outdoor heat exchanger is introduced into the indoor heat exchanger so as to remove the load in the corresponding area.

여기서, 건물 모든 영역의 부하가 설정값 보다 높은 경우에는 마이콤(161a)에 의해 모든 유량제어밸브(162a,162b,162c)가 열리면서 실외측 열교환기를 거친 냉매가 각각의 냉매관(121a)(122a)(170a)을 통해 각 실내측 열교환기로 이동하여 건물의 모든 영역에 냉풍 또는 온풍을 공급하는 반면 건물 모든 영역의 부하가 설정값 보다 낮은 경우에는 마이콤에 의해 압축기는 정지함과 아울러 각각의 유량제어밸브(162a,162b,162c)도 닫혀 현상태를 유지하게 되는 것이다.Here, when the load of all the areas of the building is higher than the set value, all of the flow control valves 162a, 162b, and 162c are opened by the microcomputer 161a, and the refrigerant passing through the outdoor heat exchanger is the refrigerant pipe 121a and 122a. While moving to each indoor side heat exchanger through 170a to supply cold or warm air to all areas of the building, if the load of all areas of the building is lower than the set value, the compressor is stopped by the microcomputer and each flow control valve (162a, 162b, and 162c) are also closed to maintain the present state.

이렇게 하여, 한 개의 실외기로도 건물의 모든 영역에 구비한 각각의 실내기를 유기적으로 운전할 수 있어 비용을 절감할 수 있을 뿐만 아니라 필요에 따라 실내기를 더 설치하더라도 별도의 실외기를 추가할 필요가 없어 비용을 더욱 절감할 수 있다. In this way, each indoor unit installed in all areas of the building can be operated organically even with one outdoor unit, which not only saves costs but also eliminates the need to add a separate outdoor unit even if additional indoor units are installed if necessary. Can further reduce.

본 발명에 의한 유니터리 에어콘의 다중 분배 장치는, 한 개의 실외기에 여러 개의 실내기를 병렬 연결하고 그 사이에 냉매를 분배 순환시킬 수 있는 냉매분배기를 설치함으로써, 한 개의 실외기로 여러 개의 실내기를 운전시킬 수 있고 필요에 따라 실내기를 더 설치하더라도 별도의 실외기를 추가할 필요가 없어 비용을 크게 절감할 수 있다. In the unitary air conditioner's multiple distribution device according to the present invention, by connecting a plurality of indoor units in one outdoor unit in parallel and installing a refrigerant distributor that distributes and circulates the refrigerant therebetween, it is possible to operate several indoor units in one outdoor unit. If necessary, even if an indoor unit is installed more, there is no need to add a separate outdoor unit, thereby greatly reducing the cost.
