본 고안은 삼방밸브 및 전자밸브를 사용하여 한개의 실외측 열교환기로 2개의 실내측 열교환기를 교환 운전할 수 있게한 2실 절환방식의 냉난방공기 조화장치에 관한 것이다.The present invention relates to a two-room switching type air-conditioning and air conditioner that can exchange two indoor heat exchangers with one outdoor heat exchanger using a three-way valve and a solenoid valve.

종래에는 거주용이나 사무실용에 분리형 공기조화기는 한개의 실외측 열교환기로 같은 실내측 열교환기를 사용하여야 하는 결점이 있었다.Conventionally, a separate air conditioner for residential or office use has a drawback of using an indoor side heat exchanger such as one outdoor side heat exchanger.

본 고안은 이러한 결점을 해소하고자 하나의 실외측 열교환기로 두개의 실내측 열교환기를 교대로 절환하여 사용할 수 있게 한 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention allows to use two indoor side heat exchangers alternately to one outdoor side heat exchanger to solve this drawback, which will be described in detail with reference to the accompanying drawings.

압축기(1)에서 사방밸브(2), 실외열교환기(3)및 모세관(4)을 통하여 접점(L)에서 바이패스하여 실내유니트(A)(B)의 냉방시 모두 폐쇄되고 난방시 교대로 폐쇄 또는 개방되는 전자밸브(7)(8)와 유니트 선택용 삼방밸브(6)을 거쳐 상호 연결된 각 유니트(A)(B)에 접속하고 상기 유니트(A)(B)사이의 접점(C)은 체크밸브(5-3)을 거쳐 압축기(1)로 연결하며 접점(D)과 접점(L)사이에 냉방용 체크밸브(5-1)와 난방용 체크밸브(5-2)를 설치함과 아울러 그 사이의 접점(F)와 상기 삼방밸브(6)를 접속하여서 된 것이다.The compressor (1) bypasses the contact (L) through the four-way valve (2), the outdoor heat exchanger (3), and the capillary tube (4) to close all of the cooling of the interior unit (A) and (B), and alternately at heating. Contact (C) between the units (A) and (B) connected to each other interconnected via a solenoid valve (7) (8) that is closed or open and a three-way valve (6) for unit selection. Is connected to the compressor (1) via a check valve (5-3) and a cooling check valve (5-1) and a heating check valve (5-2) are installed between the contact point (D) and the contact point (L). In addition, the contact F between them and the three-way valve 6 are connected.

이와같은 구성으로 된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention with such a configuration as follows.

먼저 제 제1(a)도에서와 같이 실내유니트(A)를 냉방하는경우 유니트자체의 운전스위치를 온시키면 압축기(1)와 사방밸브(2)를 통한 고온고압의 냉매가 실내측 열교환기(3)를 통과하면서 응축되어 실외에서 열교환을 하면서 방열하게 되고 실외측 열교환기(3)를 통과한 냉매는 모세관(4)를 통하여 감압되면서 냉매가 체크밸브(5-1)를 따라 삼방밸브(6)로 들어간다.First, as shown in FIG. 1 (a), when the indoor unit A is cooled, when the operation switch of the unit itself is turned on, the high temperature and high pressure refrigerant through the compressor 1 and the four-way valve 2 is supplied to the indoor heat exchanger. Condensed while passing through 3) and heat dissipated by heat exchange in the open air, and the refrigerant passing through the outdoor heat exchanger 3 is decompressed through the capillary tube 4 while the refrigerant flows along the check valve 5-1 to the three-way valve 6. Enter).

이때 각 실내유니트(A)(B)를 선택하는 삼방밸브(6)가 통전되어 위쪽으로 개방되고 화살표 방향으로 진행되며 전자밸브(7)(8)는 냉방시에 모두 오프된 상태이기 때문에 실내유니트(A)로 유입 증발되고 실내의 열을 흡수하면서 체크밸브(5-3)를 통하여 저온저압의 냉매가 압축기로 순환되게 된다.At this time, the three-way valve 6 for selecting each indoor unit (A) (B) is energized to open upward and proceed in the direction of the arrow, and the solenoid valves 7 and 8 are all turned off at the time of cooling. The refrigerant of low temperature and low pressure is circulated to the compressor through the check valve 5-3 while inflowing and evaporating to (A) and absorbing heat in the room.

또한 냉방중인 실내유니트(A)의 실내온도가 목요온도로 내려가게 되면 실내유니트(A)의 써머스타트(Thermostat)에 의해 릴레이동작으로 실내 유니트(A)의 가동을 정지시키게 되며 릴레이접점이 다른쪽에 붙어 실내유니트(B)의 냉방으로 절환된다.In addition, when the indoor temperature of the indoor unit (A) is cooled to the critical temperature, the thermostat of the indoor unit (A) stops the operation of the indoor unit (A) by the relay operation. Switch to cooling the indoor unit (B).

즉 제1(b)도는 실내유니트(B)의 냉방흐름을 나타낸다.1 (b) shows the cooling flow of the indoor unit (B).

상술한 바와같이 압축기(1)와 사방밸브(2)를 통한 고온고압의 냉매는 열교환기(3)와 체크밸브(5-1)를 거쳐 체크밸브(5-2)로는 흐를수 없기때문에 삽방밸브(6)에 도달하게 되면 이 삼방밸브(6)는 이미 아래측으로 개방되고 전자밸브(7)(8)는 오픈된 상태이므로 접점(G)을 거쳐 실내유니트(B)에서 열교환되어 실내를 냉각시키고 체크밸브(5-3)를 통하여 압축기(1)로 순환 된다.As described above, the high-temperature, high-pressure refrigerant through the compressor 1 and the four-way valve 2 cannot flow through the heat exchanger 3 and the check valve 5-1 to the check valve 5-2, so that it is an insertion valve. When it reaches (6), the three-way valve (6) is already open to the lower side and the solenoid valves (7) and (8) are open so that they heat exchange in the room unit (B) via the contact point (G) to cool the room. It is circulated to the compressor 1 through the check valve 5-3.

한편 제1(c)도에서와 같이 실내유니트 (A)의 냉방운전시의 흐름상태를 보면 압축기(1)와 사방밸브(2)를 통한 고온고압의 냉매가 접점(D)에 이르러 체크밸브(5-3)쪽으로는 흐를 수 없기 때문에 체크밸브(5-2)를 통하여 유니트 선택용 삼방밸브(6)의 위쪽으로 통과하게 되고 접점(E)을 거쳐 실내유니트(A)에 유입되어 실내공기와 열교환시켜 난방하게 되며 실내유니트(A)를 통과한 냉매는 접점(C)에서 초기 압축기의 펌핑작용으로 고압을 받는 체크밸브(5-3)가 열리지 않기때문에 자연적으로 운전하지않는 실내유니트(B)로 냉매를 유도하게 되며 전자밸브(7)는 열리고 전자밸브(8)은 폐쇄되어 전자밸브(7), 모세관(4), 열교환기(3), 압축기(1)로 순환된다.On the other hand, as shown in FIG. 1 (c), when the flow state during the cooling operation of the indoor unit (A) is shown, the refrigerant of high temperature and high pressure through the compressor (1) and the four-way valve (2) reaches the contact point (D). Since it cannot flow toward 5-3), it passes through the check valve (5-2) above the three-way valve (6) for unit selection, and flows into the indoor unit (A) via the contact point (E). The refrigerant passing through the indoor unit (A) is heated by heat exchange, and the indoor unit (B) which does not operate naturally because the check valve (5-3) receiving high pressure is not opened due to the pumping action of the initial compressor at the contact point (C). The refrigerant is introduced into the furnace, and the solenoid valve 7 is opened and the solenoid valve 8 is closed and circulated to the solenoid valve 7, the capillary tube 4, the heat exchanger 3, and the compressor 1.

그리고 제1(d)도와 같이 실내유니트(B)를 난방할때의 경로는압축기(1), 체크밸브(5-2)를 따라서 삼방밸브(6)의 아래측으로 통과하되 이때에는 전자밸브(7)가 닫힌상태가 되기 때문에 실내유니트(B)로 유입되어 난방을 하게 되고 실내유니트(B)를 거쳐 응축된 냉매는 실내유니트(A)와 개방된 전자밸브(8)를 따라서 모세관(4)과 실외 열교환기(3), 사방밸브(2)를 거쳐 압축기(1)로 흡입된다.And the path at the time of heating the indoor unit (B) as shown in the first (d) passes through the compressor (1), the check valve (5-2) to the lower side of the three-way valve (6), at this time the solenoid valve (7) ) Is closed so that the refrigerant flows into the indoor unit (B) and condenses through the indoor unit (B), along with the capillary tube (4) along the indoor unit (A) and the open solenoid valve (8). It is sucked into the compressor 1 via the outdoor heat exchanger 3 and the four-way valve 2.

이와같은 동작으로 한개의 실외측 열교환기로 두개의 실내유니트를 절환하면서 냉난방을 수행함으로써 스플릿(spilt)형 에어콘디셔너의 설치비용과 운전비를 절감할 수 있는 장점이 있는 것이다.In this operation, by switching the two indoor units to one outdoor heat exchanger, the cooling and heating are performed, thereby reducing the installation cost and operating cost of the split type air conditioner.
