The expansion condenser (60a) is connected to the thermal condenser (52a) of the 50a through a plate heat exchanger (40a) for supplying heating water, and a receiving tank (a) is provided at the thermal outlet (51a) of the heat pipe heat exchanger (50a). The automatic pressure control valve (70a) is connected via 8a, and the automatic pressure control valve (70a) is made by connecting to lower the pressure of the refrigerant applied to the compressor (1a) through the plate heat exchanger (41a), Heat pipe heat exchanger (50a) is a heat switch during heating As a result, the heat condensing port (a) does not affect the flow of the coolant through the heat dissipation port 51a and the heat condensation port 52a. It lowers the temperature of the refrigerant flowing to 52a).
그리고, 본 발명의 히트파이프 열교환기(50a)는 열응축구(52a)에서 열방출구(51a)로 사이폰 응축부(53a)를 통한 후 체크밸브(54a)를 통하여 열매체가 이동할 수 있도록 함으로써 냉방시 냉매의 효율을 높여주도록 한다.In addition, the heat pipe heat exchanger (50a) of the present invention through the siphon condensing part (53a) from the heat condenser (52a) to the heat discharge port (51a) through the check valve (54a) to move the heat medium during cooling Increase the efficiency of the refrigerant.
그러나 상기 된 방식은 한냉지에서의 난방 운전시에는 냉매 온도가 40-45oC 정도가 되어 하나의 판형 열교환기를 이용하여서는 충분한 난방온도를 만들지 못하는 문제가 발생하게 되고, 이를 감안하여 냉매의 온도를 50-55oC 로 높여줄 경우 냉방 사이클의 과냉 현상이 발생하여 운전에 무리가 따르게 된다.However, in the above-described method, when the heating operation is performed in a cold district, the refrigerant temperature is about 40-45 o C, and a problem arises in that it is impossible to make a sufficient heating temperature using a single plate heat exchanger. Increasing the temperature to 50-55 o C will cause overcooling of the cooling cycle, which will put a strain on the operation.
그리고, 난방 운전시 압축기로 유입되는 냉매의 온도가 급격히 낮아지는 경우 액체 상태로 회수되는 량이 많아져 압축기의 손상이 발생하는 것이었다.In addition, when the temperature of the refrigerant flowing into the compressor rapidly decreases during the heating operation, the amount of recovery in the liquid state increases, causing damage to the compressor.
본 발명은 상기와 같은 점을 감안하여 안출한 것으로, 두 개의 판형 열교환기를 이용하여 난방이 이루어지도록 하는 한편 이중관을 사용하여 난방운전시 압축기로 회수되는 냉매의 온도를 높여 과냉이 이루어지지 않도록 하는 한편 실외기를 거친 냉매의 온도를 판형 열교환기를 거친 냉매로 높여주어 냉매의 과냉을 방지하는 동시에 실외기로 유입되기 전의 냉매가 과열되는 것을 방지하도록 하는 것이다.The present invention has been made in view of the above point, while the heating is achieved by using two plate heat exchangers while using a double pipe to increase the temperature of the refrigerant recovered by the compressor during the heating operation to prevent overcooling The temperature of the refrigerant passing through the outdoor unit is increased to the refrigerant passing through the plate heat exchanger to prevent overcooling of the refrigerant and to prevent the refrigerant from being overheated before being introduced into the outdoor unit.

After passing through the line, the refrigerant passing through the refrigerant line of the heat exchanger passes through the double pipe, passes through the refrigerant line of the plate heat exchanger, selectively passes through a check valve and an expansion valve, and then flows into the heat outlet of the heat pipe heat exchanger. The refrigerant passing through the heat outlet of the heat pipe heat exchanger passes through the receiving tank and passes through the high pressure line of the plate heat exchanger, and the refrigerant passing through the high pressure line of the plate heat exchanger passes through the expansion valve and the check valve selectively and flows into the outdoor unit. The refrigerant recovered from the 4-way valve passes through the inner pipe of the double pipe and then flows through the accumulator to the compressor. By using a double pipe, the temperature of the refrigerant recovered by the compressor is compensated by the high temperature refrigerant during heating, while the high temperature refrigerant passing through the outdoor unit cools down to the refrigerant passing through the plate heat exchanger and at the same time compensates the refrigerant flowing into the outdoor unit. It is to ensure that the heating in the area is also heated.

In order to achieve this, the temperature of the refrigerant recovered by the compressor is increased when using the high-temperature refrigerant for high temperature hot water, thereby preventing the refrigerant from being overcooled and compensating for the temperature of the refrigerant flowing into the outdoor unit.
또한 본 발명은 난방 운전시 압축기로 회수되는 냉매의 온도를 이중관에서 높여주어 과냉을 방지하는 한편 판형 열교환기를 이용하여 냉매의 온도를 보상해 주도록 함으로써 한냉 지역에서도 충분한 난방과 고온이 온수 공급이 이루어지도록 하는 효과가 있다.In addition, the present invention is to increase the temperature of the refrigerant recovered by the compressor during the heating operation in the double pipe to prevent overcooling and to compensate the temperature of the refrigerant by using a plate heat exchanger so that sufficient heating and hot water supply in the cold region It is effective.

그리고 본 발명의 바이패스 라인(30)은 리시브 탱크(4)에 채워진 냉매의 압력이 설정 압력보다 높을 경우 작동하여 냉매가 바이패스 되게 압력을 낮추어 주게 된다.In addition, the bypass line 30 of the present invention operates when the pressure of the refrigerant filled in the receive tank 4 is higher than the set pressure, thereby lowering the pressure to bypass the refrigerant.
이러한 구성의 본 발명에서 먼저 냉방 운전시를 살펴본다In the present invention of such a configuration looks first at the cooling operation
냉방운전을 하는 경우 4방 밸브(10)는 절환되어 압축기(1)에서 압축된 냉매가 오일 분리기(2)에서 4방 밸브(10)를 거치고 판형 열교환기(80)의 저압라인을 거친 후 실외기(11)로 유입되게 하고, 실외기(11)에서는 팬의 바람을 이용하여 일정온도로 냉매의 온도를 낮추어주게 되며, 실외기(11)를 통과한 냉매는 판형 교환기(80)의 고압라인을 거치고 리시브탱크(4)를 거친 후 히트파이프 열교환기(50)의 열방출구(51)를 거치고 팽창밸브(6)에서 팽창된 후 판형 열교환기(70)로 흐르게 되고, 상기 판형 열교환기(70)를 거친 냉매는 이중관(20)을 통한 후 판형 열교환기(60)를 거쳐 히트파이프 열교환기(50)의 열응축구(52)로 흐르게 하며, 상기 열응축구(52)를 통과한 냉매는 4방 밸브(10)에서 이중관(20)의 내파이프(21)를 거친 후 어큐므레이터(3)를 거쳐 압축기(1)로 유입되게 된다.In the case of the cooling operation, the four-way valve 10 is switched so that the refrigerant compressed by the compressor 1 passes through the four-way valve 10 in the oil separator 2 and passes through the low pressure line of the plate heat exchanger 80. In the outdoor unit 11, the outdoor unit 11 lowers the temperature of the refrigerant to a predetermined temperature using the wind of the fan, and the refrigerant passing through the outdoor unit 11 passes through the high pressure line of the plate exchanger 80 and receives the receiver. After passing through the tank (4) through the heat discharge port 51 of the heat pipe heat exchanger (50) is expanded in the expansion valve (6) and flows to the plate heat exchanger (70), and passes through the plate heat exchanger (70) The refrigerant flows through the double pipe 20 and then through the plate heat exchanger 60 to the heat condensing port 52 of the heat pipe heat exchanger 50. The refrigerant passing through the heat condensing port 52 is a four-way valve 10. After passing through the inner pipe 21 of the double pipe (20) through the accumulator (3) is introduced into the compressor (1).
두 개의 판형 열교환기(60)(70)를 흐르는 냉매는 팽창밸브(6)에서 팽창이 이루어져 온도가 낮아지게 되므로, 판형 열교환기(60)(70)의 일측 라인으로 흐르는 물을 냉각시키도록 함으로써 두 개의 판형 열교환기(60)(70)를 직렬로 거친 물은 온도가 낮아 냉방용으로 사용된다.Since the refrigerant flowing through the two plate heat exchangers 60 and 70 is expanded in the expansion valve 6 to lower the temperature, the refrigerant flowing in one line of the plate heat exchanger 60 and 70 is cooled. Water passing through two plate heat exchangers 60 and 70 in series is used for cooling due to low temperature.
즉, 두 개의 판형 열교환기(60)(70)를 거친 물은 냉각이 이루어져 냉방용으로 사용하게 된다.That is, the water passing through the two plate heat exchangers 60 and 70 is cooled and used for cooling.
이와 같이 두 개의 판형 열교환기(60)(70)에서 물을 냉각시키게 되면 상대적으로 냉매의 온도가 상승되게 되므로, 본 발명에서는 이중관(20)을 이용하여 냉매의 온도를 낮춘 후 압축기(1)로 회수되게 한다.As such, when the water is cooled in the two plate heat exchangers 60 and 70, the temperature of the refrigerant is relatively increased. In the present invention, the temperature of the refrigerant is reduced by using the double pipe 20 to the compressor 1. Allow recovery.
즉, 이중관(20)에는 판형 열교환기(70)를 거친 냉매가 판형 열교환기(60)를 거치기 전에 내파이프(21)의 외측으로 흐르게 되어 비교적 낮은 온도의 냉매가 흐르게 되고, 내파이프(21)에는 판형 열교환기(60)를 거친 후 히트파이프 열교환기(50)를 거친 비교적 높은 온도의 냉매가 흐르게 되므로, 판형 열교환기(60)와 히트파이프 열교환기(50)를 거친 냉매의 온도가 판형 열교환기(70)를 거친 냉매의 온도보다 높아, 결국 압축기(1)로 회수되는 냉매의 온도를 낮추어 회수되게 한다.That is, in the double pipe 20, the refrigerant having passed through the plate heat exchanger 70 flows to the outside of the inner pipe 21 before passing through the plate heat exchanger 60, so that the refrigerant having a relatively low temperature flows, and the inner pipe 21 passes. Since the refrigerant having a relatively high temperature flows through the heat exchanger 50 after passing through the plate heat exchanger 60, the temperature of the refrigerant passing through the plate heat exchanger 60 and the heat pipe heat exchanger 50 is changed to the plate heat exchanger. It is higher than the temperature of the refrigerant passing through the group 70, and eventually lowers the temperature of the refrigerant recovered to the compressor (1) to be recovered.
그리고, 냉방 운전시는 판형 열교환기(80)에서 실외기(11)를 거치기 전과 거힌 후의 냉매 온도 보상을 해주게 되나, 별다른 변화 없이 냉방이 이루어진다.In the cooling operation, the temperature of the refrigerant is compensated before and after passing through the outdoor unit 11 in the plate heat exchanger 80, but cooling is performed without any change.
이와 같이 냉방 운전시 판형 열교환기(60)(70)를 통과한 냉매는 비교적 높은 온도를 갖게 되어, 히트파이프 열교환기(50)의 열응축구(52)를 흐르면서 열방출구(51)로 흐르는 비교적 낮은 온도의 냉매에 의해 온도가 낮추어지게 된다.As such, the refrigerant passing through the plate heat exchangers 60 and 70 during the cooling operation has a relatively high temperature, and flows to the heat discharge ports 51 while flowing through the heat condensing holes 52 of the heat pipe heat exchanger 50. The temperature is lowered by the temperature of the refrigerant.
이와는 반대로 한냉 지역에서의 난방 운전시를 살펴본다.On the contrary, the heating operation in the cold region is examined.
한냉 지역의 난방과 고온의 온수를 사용하기 위해서는 통상 냉매의 온도가 40-45oC정도에서 50-55oC가 되도록 고압으로 높여서 사용하여야 하므로, 판형 열교환기(60)(70)에서 물을 가열시켜 난방수나 온수로 공급한 후에는 고압의 냉매가 과냉 되지 않도록 온도를 높여 보상해주어야 하며, 이를 위한 것이 이중관(20)과 판형 열교환기(80)이다.In order to use the hot water in the cold region and high temperature hot water, the temperature of the refrigerant should generally be used at a high pressure such that the temperature of the refrigerant is about 40-45 o C to 50-55 o C. After heating and supplying the heating water or hot water to compensate for the high temperature so as not to overcool the refrigerant of high pressure, for this purpose is the double tube 20 and the plate heat exchanger (80).
즉, 난방 운전시 이중관(20)과 판형 열교환기(80)에서 냉매의 과냉을 방지하는 것이다.That is, to prevent overcooling of the refrigerant in the double tube 20 and the plate heat exchanger 80 during the heating operation.
난방 운전시는 4방 밸브(10)를 절환시켜 압축기(1)에서 압축된 냉매가 히트파이프 열교환기(50)의 열응축구(52)를 통한 후 판형 열교환기(60)의 냉매라인을 거친 후 이중관(20)을 거쳐 다시 판형 열교환기(70)의 냉매라인을 거치도록 한다.During the heating operation, the four-way valve 10 is switched so that the refrigerant compressed by the compressor 1 passes through the heat condenser 52 of the heat pipe heat exchanger 50, and then passes through the refrigerant line of the plate heat exchanger 60. Through the double pipe 20 to pass through the refrigerant line of the plate heat exchanger 70 again.
이때 판형 열교환기(60)(70)를 고온 고압의 냉매가 흐르면서 타측으로 흐르는 물을 냉매의 열로 가열시켜 충분한 온도의 난방수나 온수로 공급될 수 있도록 하며, 이러한 열교환에 의해 히트 파이프 열교환기(50)의 열방출구(51)보다 열응축구(52)의 냉매 온도가 낮고, 이중관(20)의 내파이프(21)를 흐르는 냉매의 온도가 낮아지게 된다.At this time, the plate heat exchanger 60, 70 is heated to the other side while the refrigerant of high temperature and high pressure flows to the heat of the refrigerant to be supplied to the heating water or hot water of a sufficient temperature, the heat pipe heat exchanger (50) The coolant temperature of the heat condensation port 52 is lower than that of the heat discharging port 51, and the temperature of the coolant flowing through the inner pipe 21 of the double pipe 20 is lowered.
그리고, 고온의 농수 공급을 위하여 판형 열교환기(60)(70)의 냉매라인을 흐르는 냉매의 온도는 50-55oC와 같이 높게 되므로 물의 온도를 높여 난방에 이용하기가 용이한 것으로, 두 개의 판형 열교환기(60)(70)를 통하여 직렬로 열교환이 이루어진 물은 뜨거운 난방수 또는 온수로 공급되어 한냉지역에서의 난방이나 온수 공급이 이루어진다.In addition, since the temperature of the refrigerant flowing through the refrigerant line of the plate heat exchanger (60) and (70) for high temperature supply of water is high, such as 50-55 o C, it is easy to use for heating by increasing the temperature of water. Water heat exchanged in series through the plate heat exchanger (60) (70) is supplied as hot heating water or hot water to provide heating or hot water supply in the cold region.
상기 판형 열교환기(60)(70)를 거친 냉매는 체크밸브(5)를 거친 후 히트파이프 열교환기(50)의 열방출구(51)를 통하여 리시브탱크(4)로 흐르게 되고, 상기 리시브 탱크(4)의 냉매는 판형 열교환기(80)의 고압라인을 통한 후 팽창밸브(7)를 거쳐 실외기(10)에서 냉각이 이루어지게 된다.The refrigerant having passed through the plate heat exchanger (60) and (70) passes through the check valve (5) and then flows to the receive tank (4) through the heat discharge port (51) of the heat pipe heat exchanger (50). The refrigerant of 4) is cooled in the outdoor unit 10 through the expansion valve 7 after the high pressure line of the plate heat exchanger 80.
상기 실외기(10)를 거친 냉매는 다시 판형 열교환기(80)의 저압라인을 거친 후 4방 밸브(10)로 흐르게 되고, 상기 4방 밸브(10)를 거친 냉매는 이중관(20)의 내파이프(21)를 거친 후 어큐므레이터(3)에서 압축기(1)로 흐르게 된다.The refrigerant passing through the outdoor unit 10 flows back to the four-way valve 10 after passing through the low pressure line of the plate heat exchanger 80, and the refrigerant passing through the four-way valve 10 passes through the inner pipe of the double pipe 20. After passing through (21), it flows from the accumulator (3) to the compressor (1).
여기서 고온의 온수 공급을 위하여 고압의 냉매를 사용한 관계로 압축기(1)로 회수되는 냉매의 온도가 현격히 낮게 되고, 이는 냉매의 과냉으로 이루어져 압축 효율이 떨어져 결과적으로 난방이 원활히 이루어지지 않는 경우가 발생하게 된다.Here, the temperature of the refrigerant recovered to the compressor (1) is significantly lowered due to the use of a high-pressure refrigerant for the supply of high temperature hot water, which is caused by the subcooling of the refrigerant, resulting in poor compression efficiency and consequent heating. Done.
따라서 본 발명에서는 이중관(20)과 판형 열교환기(80)를 이용하여 압축기(1)로 회수되는 냉매의 온도를 높여주어 냉매의 과냉 현상이 발생하지 않도록 하는 것이다.Therefore, in the present invention, by using the double pipe 20 and the plate heat exchanger 80 to increase the temperature of the refrigerant recovered by the compressor (1) so that the supercooling phenomenon of the refrigerant does not occur.
이와 같이 본 발명의 판형 열교환기(80)는 실외기(11)로 유입되는 고압측의 냉매 온도가 높은 것을 실외기(11)에서 배출되는 차가워진 저압측의 냉매로 보상이 이루어지게 하는 한편 실외기(11)에서 과냉된 냉매의 온도를 고압측의 높은 냉매온도로 높여주어 과냉이 방지되게 한다.As described above, the plate heat exchanger 80 of the present invention compensates for the high temperature of the refrigerant at the high pressure side flowing into the outdoor unit 11 with the cooler at the low pressure side discharged from the outdoor unit 11 while the outdoor unit 11 ) To increase the temperature of the supercooled refrigerant to a high refrigerant temperature on the high pressure side to prevent overcooling.
즉, 본 발명의 판형 열교환기(80)는 한냉지에서 난방 운전시 고온의 온수를 사용하기 위하여 냉매의 압력을 높임으로써 실외기(11)를 거친 냉매의 온도가 급격히 낮아지는 것을 방지하기 위하여 실외기(11)로 유입되는 높은 온도를 갖는 냉매로 실외기(11)에서 배출되는 냉매의 온도를 일반적인 온도로 높여줌으로써 난방 운전시의 과냉을 방지한다.That is, the plate heat exchanger 80 of the present invention increases the pressure of the refrigerant in order to use high temperature hot water during the heating operation in the cold district to prevent the temperature of the refrigerant passing through the outdoor unit 11 from being rapidly lowered. 11) The refrigerant having a high temperature introduced into the refrigerant 11 increases the temperature of the refrigerant discharged from the outdoor unit 11 to a general temperature to prevent overcooling during the heating operation.
이와 동시에 난방운전시 실외기(11)로 유입되는 높은 온도의 냉매는 판형 열교환기(80)에서 일정 온도로 보상되므로 기체 상태로의 팽창이 원활히 이루어지게 된다.At the same time, since the refrigerant having a high temperature introduced into the outdoor unit 11 during the heating operation is compensated by the constant temperature in the plate heat exchanger 80, expansion to the gas state is performed smoothly.
또한 본 발명은 이중관(20)의 내파이프(21)로 흐르는 냉매의 온도가 이중관(20)의 내파이프(21) 외측을 흐르는 냉매의 온도보다 낮아지므로, 내파이프(21)를 통하여 어큐므레이터(3)로 유입되는 냉매의 온도가 높아지게 보상함으로써, 난방 운전시 냉매의 과냉을 방지하도록 한다.In addition, in the present invention, since the temperature of the refrigerant flowing into the inner pipe 21 of the double pipe 20 is lower than the temperature of the refrigerant flowing outside the inner pipe 21 of the double pipe 20, the accumulator is provided through the inner pipe 21. By compensating for the temperature of the refrigerant flowing into (3) to be high, the supercooling of the refrigerant during the heating operation is prevented.
그리고, 본 발명의 히트파이프 열교환기(50)는 열응축구(52)를 통과하는 높은 온도의 냉매 온도가 열방출구(51)를 통과하는 냉매와 온도 보상이 이루어지게 된다.In the heat pipe heat exchanger 50 of the present invention, the temperature of the refrigerant having a high temperature passing through the heat condenser 52 and the heat passing through the heat discharge port 51 is compensated for.
