본 고안은 고추식과 냉각기에 관한 것으로 특히 냉방기나 냉동기등과 같은 냉동시스템에 부착하여 냉각효율을 증가시키고, 전력 소비를 감소 시키도록 한 것이다.The present invention relates to a chilled pepper and a chiller, in particular, to be attached to a refrigeration system such as an air conditioner or a freezer to increase cooling efficiency and reduce power consumption.

일반적으로 냉동시스템은 제1도에서 보는 바와같이 압축기(1)에서 만들어진 고온 고압의 냉매가스가 응축기(2)에서 물 혹은 공기에 의하여 열이 방출되므로서 응축되고, 이 응축된 고압의 액체냉매는 팽창밸브(3)를 통하는 동안 압력이 떨어져 저온이 되며, 팽창밸브(3)를 통한 저온의 액체냉매는 증발기(4)내를 흐르는 동안 주위로부터 열을 흡수하여 증발하게 된다.In general, as shown in FIG. 1, the refrigerating system condenses the high-temperature, high-pressure refrigerant gas produced by the compressor 1 as heat is released from the condenser 2 by water or air. The pressure drops through the expansion valve (3) and becomes low temperature, and the low temperature liquid refrigerant through the expansion valve (3) absorbs heat from the surroundings and evaporates while flowing in the evaporator (4).

즉, 액체냉매가 증발기(4)에서 기체로 변하며 이때 냉매는 증발열을 흡수하는 것이다.That is, the liquid refrigerant turns into gas in the evaporator 4, where the refrigerant absorbs the heat of evaporation.

이같은 냉동시스템에 있어 종래에는 보다 냉각 효율을 높이기 위하여 제2도에서 보는 바와같이 응축기(2)와 팽창밸브(3)사이에 열교환기(5)를 설치하여 증발기(4)에서 증발된 냉매가스를 이 열교환기(5)에 재차 통과시킨후 압축기(1)로 보내도록 하므로서 응축기(2)에서 팽창밸브(3)롤 보내어지는 냉매액을 과냉각시키도록 하는 구성이 알려져 있었다.In such a refrigeration system, a heat exchanger (5) is installed between the condenser (2) and the expansion valve (3) to improve the cooling efficiency. It has been known to supercool the refrigerant liquid sent from the condenser 2 to the expansion valve 3 by passing it through the heat exchanger 5 again and sending it to the compressor 1.

그러나, 이같은 종래의 구성은 증발기(4)에서 토출되는 일차 증발된 냉매가스가 단순히 열교환기(5)를 통과하는 정도에서 열교환이 이루어지므로서 기대한량만큼의 과냉각 효율을 얻지못하는 문제점이 있었다.However, such a conventional configuration has a problem in that the heat exchange is performed at the degree that the primary evaporated refrigerant gas discharged from the evaporator 4 simply passes through the heat exchanger 5, thereby failing to obtain the subcooling efficiency of the expected amount.

본 고안은 이와같은 종래의 제반 문제점을 시정 보완하고자 응축기와 팽창밸브 사이에 보조팽창밸브를 가진 과냉각기를 설치하여 보조 팽창밸브에 의해 감압된 냉매로 하여금 응축기로부터 유입되는 냉매액을 과냉각시키도록 한 것으로 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is to provide a subcooler having an auxiliary expansion valve between the condenser and the expansion valve to compensate for all the conventional problems such that the refrigerant depressurized by the auxiliary expansion valve to supercool the refrigerant liquid flowing from the condenser When described in detail with the accompanying drawings as follows.

통상의 내동사이클에 있어서, 응축기(2)와 팽창밸브(3) 사이에 설치되는 과냉각기(6)의 전단 유입관(7)은 응축기(2)의 액체관(8)에, 후단 배출관(9)은 팽창밸브(3)의 액체관(8)에 각각 연결한다.In a normal internal movement cycle, the front inlet pipe 7 of the supercooler 6 provided between the condenser 2 and the expansion valve 3 is connected to the liquid pipe 8 of the condenser 2 and the rear end pipe 9. Are connected to the liquid pipes 8 of the expansion valves 3, respectively.

본체(6)내측 상단으로 설치되고 다수의 분사구(10)를 갖는 유입관(7)의 일측에는 냉매액 유도관(11)을 연결하여 보조 팽창밸브(12)와 연결하고 보조팽창밸브(12)에서 나오는 연결관(13)은 과냉각기 본체(6)내에 선회된 코일관(14)의 전단과 연결하며 후단에는 보조배출관(15)을 연결하여 압축기(1)에 직접 연결하여서 된 것이다.One side of the inlet pipe (7) having a plurality of injection holes (10) installed inside the main body (6) is connected to the auxiliary expansion valve (12) by connecting the refrigerant liquid induction pipe (11) and the auxiliary expansion valve (12) The connecting pipe (13) coming out is connected to the front end of the coil pipe (14) pivoted in the subcooler main body (6) and is connected directly to the compressor (1) by connecting the auxiliary discharge pipe (15) at the rear end.

이와같은 본고안은 응축기(2)로 부터 응축된 냉매액이 유입관(7)을 통해 과냉각기(6)내부로 유입되어져 분사구(10)들에 의해 내부의 코일관(14)전체면으로 분사되어진 후 배축관(9)을 거쳐 팽창밸브(3)로 보내어지게 된다.In this paper, the refrigerant liquid condensed from the condenser (2) is introduced into the subcooler (6) through the inlet pipe (7) and sprayed to the entire surface of the coil pipe (14) by the injection holes (10). It is then sent to the expansion valve (3) via the exhaust pipe (9).

한편, 유입관(7)과 연결된 유도관(11)으로도 응축된 냉매 일부가 흐르게 되어 보조팽창밸브(12)로 유입되어 지고 보조 팽창밸브(12)를 통하는 냉매는 감압 팽창되어 연결관(13)을 통해 코일관(14)으로 유입되며 코일과(14)을 순환된 냉매는 보조배출관(15)을 거쳐 압축기(1)로 흐르게 되는 것이다.Meanwhile, a part of the condensed refrigerant also flows into the induction pipe 11 connected to the inflow pipe 7 to flow into the auxiliary expansion valve 12, and the refrigerant passing through the auxiliary expansion valve 12 is expanded under reduced pressure to connect the connection pipe 13. The refrigerant flowing into the coil pipe 14 through the coil 14 and circulated through the coil 14 flows to the compressor 1 through the auxiliary discharge pipe 15.

이때, 보조팽창밸브(12)를 통과한 냉매는 감압 팽창되어 코일관(14)내를 순환하면서 증발하게된다.At this time, the refrigerant passing through the auxiliary expansion valve 12 is expanded under reduced pressure to circulate in the coil pipe 14 to evaporate.

즉, 코일관(14)을 순환하는 액체 냉매가 기체로 변하면서 증발열을 흡수하게 되는데, 이 냉매는 분사구(10)들을 통해 분사되는 냉매액의 열을 흡수하게 되고 그런후 보조 보출관(15)을 통해 냉매가스는 압축기(1)로 보내어지게 된다.That is, the liquid refrigerant circulating in the coil tube 14 is converted into a gas to absorb the heat of evaporation, the refrigerant absorbs the heat of the refrigerant liquid injected through the injection holes 10 and then the auxiliary discharge pipe 15 Through the refrigerant gas is sent to the compressor (1).

그러므로, 유입관(7)을 통하여 과냉각기(6)내로 분사되는 냉매액은 내부코일관(14)의 차가운 표면에서 과냉각되어 극히 낮은 온도가 되어 배출관(9)를 거쳐 팽창밸브(3)로 유입되어지는 것이다.Therefore, the coolant liquid injected into the subcooler 6 through the inlet pipe 7 is supercooled at the cold surface of the inner coil pipe 14 to become extremely low temperature and flows into the expansion valve 3 through the discharge pipe 9. It is done.

이와 같이된 본 고안은 응축기(2)에서 응축된 냉매액의 일부를 보조팽창밸브(12)로 보내어 감압된 냉매로, 순환되는 냉매액을 과냉각시키므로서 과냉각기(6)를 통과한 냉매액을 더욱 낮은 온도로 팽창밸브(3)를 보내어지게 되어 증발기(4)에서의 냉각능력을 더욱 향상시킬수 있을뿐아니라 응축기(2)하부에 고여 있는 냉매액의 정체현상을 최소화 하므로서 약 15-20%까지 응축기의 능력향상을 도모할수가 있는 것이다.The present invention as described above sends a part of the refrigerant liquid condensed in the condenser (2) to the auxiliary expansion valve (12) to reduce the refrigerant, the refrigerant liquid passed through the subcooler (6) by supercooling the refrigerant liquid circulated The expansion valve (3) is sent to a lower temperature, which not only improves the cooling capacity of the evaporator (4) but also minimizes the condensation of the refrigerant liquid accumulated in the condenser (2) to about 15-20%. It is possible to improve the capacity of the condenser.

이와같이 증발기(4)와 응축기(2)의 효율이 월등히 향상되므로서 종전보다 낮은 압력조건에서도 운전이 가능하므로 냉매충진량이 적어도 되고, 이에따라 정기소비량도 25-30% 감소시킬수가 있는 유용한 고안인 것이다.Thus, since the efficiency of the evaporator 4 and the condenser 2 is greatly improved, the operation can be performed even at a lower pressure than before, and thus the amount of refrigerant filling is minimal, and accordingly, it is a useful design that can reduce the regular consumption of 25-30%.
