본 발명은 냉,난방겸용 에어컨용 사방밸브장치에 관한 것으로서, 보다 상세하게는 에어컨에 냉매의 흐름을 절환시키는 사방향밸브를 보다 간단한 구조로 형성하도록 하여 제조원가를 절감시킬 수 있으며, 아울러 냉매의 압력손실을 최대한 감소시킬 수 있도록 한 냉,난방겸용 에어컨용 사방밸브장치에 관한 것이다.The present invention relates to a four-way valve device for both air conditioning and heating, and more specifically, to form a four-way valve for switching the flow of refrigerant in the air conditioner in a simpler structure to reduce the manufacturing cost, and also the pressure of the refrigerant The present invention relates to a four-way valve device for air conditioning and heating for reducing losses as much as possible.

잘 아는 바와 같이 일정한 공간내의 온도나 습도를 일정하게 유지하여 일이 능률을 올리도록 하는 것을 공기조화라 하며, 이때 사용되는 인위적인 수단 및 장치를 공기조화장치라 한다.As is well known, air conditioning is a method of improving work efficiency by maintaining a constant temperature or humidity in a constant space, and the artificial means and apparatus used at this time are called air conditioning devices.

상기 공기조화장치는 실내의 온도를 높이는 히팅장치와, 그 온도를 낮추는 냉방장치가 있다.The air conditioner includes a heating device for raising the temperature of the room, and a cooling device for lowering the temperature.

상기 히팅장치는 열원이 산화되면서 발생되는 열을 열교환기를 이용하여 공기를 간접 가열하여 온도가 높은 상태로 재토출시킴으로써 실내를 난방하도록 한 것이다.The heating device is to heat the room by re-discharging the heat generated as the heat source is oxidized by indirect heating of the air using a heat exchanger to a high temperature state.

또한, 상기 냉방장치는 압축된 냉매가 팽창되면서 발생하는 흡열작용을 이용하여 주위의 공기를 냉각시키고, 이 냉각된 공기를 실내로 배출시킴으로써 실내를 냉방하도록 한 것이다.In addition, the cooling device uses the endothermic action generated by the expansion of the compressed refrigerant to cool the surrounding air, and discharges the cooled air into the room to cool the room.

이러한 냉방장치와 히팅장치는 하나의 유닛으로 그 내부에 흐르는 냉매의 방향을 변경하여 냉,난방을 겸하도록 에어컨에 구비된다.The cooling device and the heating device are provided in the air conditioner so as to serve as cooling and heating by changing the direction of the refrigerant flowing therein as one unit.

즉, 상기 에어컨은 여름철에는 냉매가 압축기, 응축기, 증발기로 흐르도록 하여 냉방을 하도록 하고, 겨울철에는 냉매의 흐름을 반대로 하여 응축기에서 발생하는 열을 이용하여 공기를 가열하고, 이 가열된 공기를 실내로 배출시켜 난방을 하도록 되어 있다.That is, in the summer, the air conditioner cools the refrigerant by flowing it to a compressor, a condenser and an evaporator, and in winter, reverses the flow of the refrigerant to heat the air by using heat generated from the condenser, and heats the heated air indoors. It is to be discharged to heating.

첨부도면 도 1 및 도 2는 종래의 일반적인 냉,난방겸용 에어컨의 냉매 흐름을 나타낸 구성도이다.1 and 2 is a block diagram showing the flow of the refrigerant of the conventional air-conditioning combined heating.

도시된 바와 같이 상기 에어컨(10,10a)의 전체적인 구성은 냉매를 압축시키는 압축기(11,11a)와, 이 압축기(11,11a)로부터 토출되는 고압의 냉매를 응축기(12,12a)와 실내에 설치된 증발기(13,13a)측으로 분배하는 사방밸브(14,14a)와, 상기 응축기(12,12a)를 통과한 냉매를 증발기(13,13a)의 유입측에 연결된 팽창밸브(15,15a)측으로 흐르도록 컨트롤러(16,16a)에 의해 선택적으로 온/오프(on/off)되는 제1솔레노이드밸브(17,17a)와, 상기 증발기(13,13a)를 경유한 냉매를 상기 사방밸브(14,14a)를 통해 압축기(11,11a)로 유입시 이를 제어하는 제2솔레노이드밸브(18,18a)로 구성된다.As shown in the drawing, the overall configuration of the air conditioners 10 and 10a includes compressors 11 and 11a for compressing the refrigerant and high-pressure refrigerant discharged from the compressors 11 and 11a to the condenser 12 and 12a. Four-way valves 14 and 14a for distributing to the installed evaporators 13 and 13a and refrigerant passing through the condensers 12 and 12a to the expansion valves 15 and 15a connected to the inflow side of the evaporators 13 and 13a. First solenoid valves 17 and 17a selectively turned on and off by the controllers 16 and 16a to flow, and refrigerant passing through the evaporators 13 and 13a. It is composed of second solenoid valves (18, 18a) to control the inlet to the compressor (11, 11a) through 14a).

상기 사방밸브(14,14a)는 4방향의 출구 또는 입구를 갖는 밸브로서, 도 3에 도시된 바와 같이 압축기(11,11a)의 출구측과 응축기(12,12a)의 입구측 및 증발기(13,13a)의 출구측에 연결되어 냉매의 흐름을 변경할 수 있도록 제1,2,3,4밸브(14-1,14-2,14-3,14-4,14a-1,14a-2,14a-3,14a-4)와 각각의 출구를 선택적으로 여닫을 수 있도록 그 내부가 설치되어 있다.The four-way valves 14 and 14a are valves having outlets or inlets in four directions, and as shown in FIG. 3, the outlet side of the compressors 11 and 11a and the inlet side and the evaporator 13 of the condensers 12 and 12a. 1, 2, 3, 4 valves 14-1, 14-2, 14-3, 14-4, 14a-1, 14a-2, which are connected to the outlet side of 13a to change the flow of refrigerant. 14a-3, 14a-4) and its interior are installed to selectively open and close each exit.

즉, 상기 사방밸브(14,14a)는 콘트롤러(16,16a)의 선택에 의해 솔레노이드밸브(17,18,17a,18a)의 코일(A) 측으로 전원이 인가되면, 플런저(C)가 스프링(B)력에 의해 슬라이딩 이동하게 되고, 상기 플런저(C)의 슬라이동으로 인해 냉매가스는 캐필러리튜브(D)를 통하여 상기 사방밸브(14,14a)의 내측에 구비되는 피스톤(E)을 이동시키게 된다. 상기 피스톤(E)의 이동으로 슬라이드밸브(F)가 슬라이드 이동하여 냉매의 흐름을 변경시키도록 이루어져 있다.That is, the four-way valve (14, 14a) is applied to the coil (A) side of the solenoid valve (17, 18, 17a, 18a) by the selection of the controller (16, 16a), the plunger (C) is a spring ( B) the sliding movement by the force, the refrigerant gas due to the sliding of the plunger (C) through the capillary tube (D) the piston (E) provided on the inside of the four-way valve (14,14a) Will be moved. The slide valve (F) is moved by the movement of the piston (E) is made to change the flow of the refrigerant.

이러한, 냉,난방겸용 에어컨(10,10a)의 냉방운전시에는 도 1에 도시된 바와 같이 압축기(11)로부터 압축된 냉매는 사향밸브(14)의 제1밸브(14-1)(출구)로 유입된 후, 제2밸브(14-2)(입구)인 출구를 통해 응축기(12)를 통과하는 과정에서 액체상태로 냉각된다.During the cooling operation of the air conditioners 10 and 10a for both air conditioning and cooling, the refrigerant compressed from the compressor 11 as shown in FIG. 1 is the first valve 14-1 (outlet) of the musk valve 14. After flowing in, the liquid is cooled in a state of passing through the condenser 12 through an outlet, which is the second valve 14-2 (inlet).

액체 상태에서의 냉매는 컨트롤러(16)의 신호에 따라 제1솔레노이드밸브(17)의 플런저(C)가 스프링(B)력에 의해 이동하고, 상기 플런저(C)의 이동으로 캐필러리튜브(D)를 통하여 냉매가 피스톤(E)을 밀게 된다. 상기 피스톤(E)의 밀림으로 슬라이드밸브(F)가 슬라이드 이동하여 냉매가스는 팽창밸브(15)를 경유하게 되면서, 압력강하 작용으로 저온,저압으로 변환된다.As for the refrigerant in the liquid state, the plunger C of the first solenoid valve 17 is moved by the spring B force according to the signal of the controller 16, and the capillary tube is moved by the movement of the plunger C. The refrigerant pushes the piston E through D). As the slide valve (F) slides by the push of the piston (E), the refrigerant gas passes through the expansion valve (15), and is converted to low temperature and low pressure by a pressure drop action.

변환된 저온,저압의 냉매는 실내에 설치된 증발기(13)를 통과하면서 그 주위의 공기를 냉각시키고, 이 냉각된 공기를 실내로 배출시켜 냉방을 하게 된다.The converted low temperature and low pressure refrigerant passes through the evaporator 13 installed in the room to cool the air around it, and discharges the cooled air to the room for cooling.

그리고, 증발기(13)를 통과한 냉매는 제2솔레노이드밸브(18)를 통과한 후, 사방밸브(14)의 제3밸브(14-3)와 제4밸브(14-4)를 통해 압축기(11)의 흡입측으로 유입된다.After passing through the second solenoid valve 18, the refrigerant passing through the evaporator 13 passes through the third valve 14-3 and the fourth valve 14-4 of the four-way valve 14. 11) flows into the suction side.

한편, 냉,난방겸용 에어컨(10a)의 난방운전시에는 도 2에 도시된 바와 같이 압축기(11a)로부터 압축된 냉매는 사방밸브(14a)의 제1밸브(14a-1)로 유입된 후, 제3밸브(14a-3)를 통해 배출된다. 이후, 제2솔레노이드밸브(18a)를 거쳐 실내에 설치된 증발기(13a)를 통과하는 과정에서 냉방시 증발기(13a)의 작용이 역으로 변환되어 응축기(12a)의 작용을 하게 된다.On the other hand, during the heating operation of the air-conditioning (10a) for both heating and cooling, as shown in Figure 2 after the refrigerant compressed from the compressor (11a) flows into the first valve (14a-1) of the four-way valve (14a), It is discharged through the third valve 14a-3. Thereafter, in the course of passing through the evaporator 13a installed indoors via the second solenoid valve 18a, the action of the evaporator 13a is reversed to act as the condenser 12a.

즉, 고온, 고압의 냉매가 증발기(13a)내를 흐르면서 주위의 공기와 열교환이 이루어지고, 이로 인해 공기의 온도가 높아지게 되며, 이 높아진 공기를 실내로 배출시켜 난방을 하게 된다.That is, the high-temperature, high-pressure refrigerant flows through the evaporator 13a and heat exchanges with the surrounding air, thereby increasing the temperature of the air, thereby discharging the elevated air into the room to heat it.

이와 같이 냉,난방겸용 에어컨은 스프링력에 의해 플런저가 좌,우슬라이드 이동하면서 캐필러리튜브측으로 냉매가 흘러 피스톤을 작동시키고 이로 인해 슬라이드밸브가 이동되면서 냉매의 방향을 절환시키는 사방밸브에 의해 냉,난방겸용 에어컨을 사용토록 하고 있다. 그러나, 이와 같이 사방밸브는 냉매를 이용하여 방향을 절환시키도록 이루어져 있어서 냉매의 손실이 발생되어 에어컨의 성능을 저하시키는 원인이 되었다.As such, the air conditioner for cooling and heating is cooled by a four-way valve that switches the direction of the refrigerant by moving the plunger to the capillary tube while the plunger moves to the left and right slides by the spring force, thereby moving the slide valve. I am using a heating and air conditioning system. However, in this way, the four-way valve is configured to switch the direction by using the refrigerant, so that loss of the refrigerant occurs, which causes a decrease in the performance of the air conditioner.

또한, 상기 사방밸브는 캐필러리튜브, 피스톤, 슬라이드밸브와 같이 여러부재로 이루어져 있어서 그 구조가 매우 복잡하며, 아울러, 사방밸브는 솔레노이드밸브의 플런저를 계속적으로 작동시켜야 함으로 지속적인 전원공급이 요구되는 문제점이 있었다.In addition, the four-way valve is composed of a number of members, such as capillary tube, piston, slide valve, the structure is very complicated, and four-way valve is required to continuously operate the plunger of the solenoid valve is required for continuous power supply There was a problem.

이에, 본 발명은 상기와 같은 문제점을 해소하기 위해 안출된 것으로서, 냉매의 방향을 절환시키는 냉,난방겸용 에어컨의 사방밸브를 모터에 의해 회동되는 절환밸브를 갖춘 간단한 구조로 하여 그에 따른 제조원가를 절감시킬 수 있고, 아울러, 최초 절환밸브를 회동시킨 후 전원을 차단시켜도 그 상태를 유지하도록 하여 소비전력을 감소시킬 수 있으며, 냉매의 손실을 방지하여 에어컨의 성능을 향상시킬 수 있도록 한 냉,난방겸용 에어컨용 사방밸브장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, the four-way valve of the cooling and heating air conditioner for switching the direction of the refrigerant to a simple structure having a switching valve rotated by a motor to reduce the manufacturing cost accordingly In addition, it is possible to reduce the power consumption by maintaining the state even after the power switch is turned off after the initial switching valve is turned on, and it is a cooling / heating combination that improves the performance of the air conditioner by preventing the loss of refrigerant. The purpose is to provide a four-way valve device for air conditioning.

상술한 목적을 달성하기 위한 본 발명은 냉,난방겸용 에어컨에 구비되어 냉매의 방향을 절환시켜 하나의 에컨의 냉,난방을 겸하도록 하는 사방밸브장치에 있어서, 상기 사방밸브장치는 몸체와; 이 몸체에 그 내부가 서로 연통되게 이루어지되, 그 내부에 냉매의 방향을 절환시키는 절환밸브와; 이 절환밸브를 회동시킬 수 있도록 전원부로부터 전원을 공급받아 컨트롤러에 의해 제어되는 정,역구동가능한 모터;를 포함하여 이루어진 것을 특징으로 한다.The present invention for achieving the above object is provided in the air-conditioner for cooling and heating, the four-way valve device to switch the direction of the refrigerant to serve as cooling and heating of a single cone, the four-way valve device and the body; The body is made to communicate with each other in the body, the switching valve for switching the direction of the refrigerant therein; It is characterized in that it comprises a; forward and reverse drive motor which is controlled by the controller by receiving power from the power supply to rotate the switching valve.

도시된 바와 같이 냉매를 압축시키는 압축기로부터 냉,난방시 각각 냉매의방향을 절환시키는 사방밸브(100)는 직육면체로 이루어져 그 내부가 서로 연통되어 압축기의 고압측에 연결되는 제1홀(105a)과, 실외측에 설치되는 응축기와 연결되는 제2홀(105b)과, 실내측에 구비되는 증발기와 연결되는 제3홀(105c)과, 저압 냉매가 압축기측으로 유입되는 제4홀(105c)을 갖춘 몸체(105)와, 이 몸체(105)의 내부에는 냉,난방에 대응되게 압축기로부터 배출되는 냉매가스를 응축기와 증발기측으로 방향을 절환시키도록 회동가능하게 구비되는 절환밸브(110)와, 상기 몸체(105)의 상면에는 절환밸브(110)를 회동시킬 수 있도록 전원부로부터 전원을 공급받아 컨트롤러에 의해 제어되는 정,역구동가능한 모터(115)로 이루어진다.As shown, the four-way valve 100 for switching the direction of the refrigerant at the time of cooling and heating from the compressor for compressing the refrigerant consists of a rectangular parallelepiped, the interior of which communicates with each other and is connected to the high pressure side of the compressor. And a second hole 105b connected to the condenser installed at the outdoor side, a third hole 105c connected to the evaporator provided at the indoor side, and a fourth hole 105c at which the low pressure refrigerant flows into the compressor side. The body 105, and the inside of the body 105, the switching valve 110 is provided rotatably to switch the refrigerant gas discharged from the compressor to the condenser and the evaporator side corresponding to cooling and heating, and the body The upper surface of the 105 is composed of a forward and reverse drive motor 115 is supplied by the power supply from the power supply so as to rotate the switching valve 110 is controlled by a controller.

이와 같이 이루어진 본 발명에 따른 사방밸브(100)를 냉,난방겸용 에어컨에 설치하여 에어컨을 냉방으로 구동시키면, 도 4 및 도 5에 도시된 바와 같이 컨트롤러는 사방밸브(100)의 몸체(105) 상면에 구비되는 모터(115)측으로 전원을 인가시켜 모터(115)를 구동시키게 된다.When the four-way valve 100 according to the present invention made in this way is installed in the air-conditioning and air-conditioning combined air conditioner to drive the air conditioner, as shown in Figures 4 and 5, the controller 105 of the four-way valve 100 The motor 115 is driven by applying power to the motor 115 provided on the upper surface.

상기 모터(115)의 구동으로 사방밸브(100)의 몸체(105) 내측에 설치된 절환밸브(110)가 회동하게 되고, 이로 인해 압축기의 출구측과 연결된 제1홀(105a)과 실외측에 설치된 응축기의 입구측에 연결되는 제2홀(105b)이 서로 연통되게 된다.The switching valve 110 installed inside the body 105 of the four-way valve 100 is rotated by the driving of the motor 115, and thus the first hole 105a connected to the outlet side of the compressor and the outdoor side are installed. The second hole 105b connected to the inlet side of the condenser is in communication with each other.

상기 절환밸브(110)의 회동으로 압축기에서 고온,고압의 변환된 냉매가스는 사방밸브(100)의 제1홀(105a)을 통하여 몸체내측에 절환된 절환밸브(110)에 의해 응축기측으로 이동하면서 팽창밸브를 경유하여 압력강하 작용으로 저온,저압으로 변환된다.The refrigerant gas of the high temperature and high pressure converted in the compressor by the rotation of the switching valve 110 is moved to the condenser side by the switching valve 110 switched inside the body through the first hole 105a of the four-way valve 100. It is converted into low temperature and low pressure by the pressure drop action through the expansion valve.

상기 팽창밸브를 경유하여 저온,저압으로 변환된 냉매는 실내에 설치된 증발기를 통과하면서 그 주위의 공기를 냉각시키고, 이 냉각된 공기를 실내로 배출시켜 냉방을 하게 된다.The refrigerant converted to low temperature and low pressure via the expansion valve passes through an evaporator installed in the room to cool the air around it, and discharges the cooled air to the room for cooling.

이와 같이 사방밸브장치가 구비된 에어컨을 난방운전을 하게 되면, 컨트롤러는 사방밸브(100)의 몸체(105) 상면에 구비된 모터(115)를 냉방시와 반대방향으로 역구동 구동하여 상기 몸체(105)의 내부에 설치된 절환밸브(110)를 회동시키게 된다. 상기 절환밸브(110)의 회동으로 인해 압축기의 출구측과 연결된 제1홀(105a)과 실내측에 설치된 증발기의 입구측에 연결되는 제3홀(105c)을 연통시키게 된다.When the heating operation of the air conditioner provided with a four-way valve device as described above, the controller drives the motor 115 provided on the upper surface of the body 105 of the four-way valve 100 in the reverse direction in the opposite direction of cooling the body ( The switching valve 110 installed inside the 105 is rotated. Due to the rotation of the switching valve 110 to communicate with the first hole 105a connected to the outlet side of the compressor and the third hole 105c connected to the inlet side of the evaporator installed in the room side.

따라서, 압축기로부터 압축된 냉매는 사방밸브(100)의 제1홀(105a)로 유출된 후, 제3홀(105c)을 통해 실내측에 설치된 증발기를 통과하게 되고, 이 증발기를 통과하는 과정에서 냉방시 증발기의 작용이 역으로 변환되어 응축기의 작용을 하게 된다.Therefore, the refrigerant compressed from the compressor flows out into the first hole 105a of the four-way valve 100 and then passes through an evaporator installed in the room side through the third hole 105c, and passes through the evaporator. During cooling, the action of the evaporator is reversed to act as a condenser.

즉, 고온, 고압의 냉매가 증발기내를 흐르면서 주위의 공기와 열교환이 이루어지고, 이로 인해 공기의 온도가 높아지게 되며, 이 높아진 공기를 실내로 배출시켜 난방을 하게 된다.That is, the high-temperature, high-pressure refrigerant flows through the evaporator and heat exchanges with the surrounding air, thereby increasing the temperature of the air, thereby discharging the elevated air into the room to heat it.

이와 같이 이루어진 사방밸브장치를 냉,난방겸용 에어컨에 설치함으로써, 모터의 구동으로 냉매의 방향을 간편 절환시킬 수 있다. 아울러, 상기 모터의 구동은 최초 절환밸브의 방향을 절환시킨 후에는 상기 모터측으로 인가되는 전원을 차단하여도 냉매로 인해 그 절환된 상태를 계속적으로 유지할 수 있어서 전력 소비를 감소시킬 수도 있다.By installing the four-way valve device configured as described above in both a cooling and heating air conditioner, the direction of the refrigerant can be easily switched by driving the motor. In addition, after switching the direction of the first switching valve, the driving of the motor may continuously maintain the switched state due to the refrigerant even when the power applied to the motor side is cut off, thereby reducing power consumption.

전술한 바와 같이 본 발명은 몸체 내부에 모터의 구동력에 의해 회동되어 그 내부로 흐르는 냉매의 방향을 간단하게 절환시키는 절환밸브를 갖는 사방밸브를 갖춤으로써 이의 제조원가를 절감시킬 수 있고, 또한 압축기로부터 배출되는 냉매가스가 직접 응축기 또는 증발기측으로 유입되므로 냉매의 압력손실을 방지할 수 있어서 에어컨의 성능저하를 방지할 수 있으며, 나아가 모터측으로 인가된 전원은 최초 절환밸브의 회동에 필요한 전원만 공급하면 되므로 소비전력을 감소시킬 수 있는 효과가 있다.As described above, the present invention can reduce the manufacturing cost by having a four-way valve having a switching valve that is simply rotated by the driving force of the motor inside the body to switch the direction of the refrigerant flowing therein, and also discharged from the compressor Since the refrigerant gas flows directly into the condenser or evaporator side, it is possible to prevent the pressure loss of the refrigerant, thereby preventing the deterioration of the air conditioner. There is an effect that can reduce the power.
