본 고안은 공기조화기의 냉매순환구조에 관한 것으로써, 더욱 상세하게는 응축기를 통과한 고온.고압의 냉매가 모세관을 통과하기 이전에 증발기를 거치게 함에 따라 저온.저압으로 변화되게 한 상태에서 냉각싸이클을 수행할 수 있게 한 공기조화기의 냉매순환구조에 관한 것이다.The present invention relates to a refrigerant circulation structure of an air conditioner, and more particularly, a high-temperature / high-pressure refrigerant passing through a condenser passes through an evaporator before passing through a capillary tube, and is cooled at a low-temperature / low-pressure state. It relates to a refrigerant circulation structure of an air conditioner capable of carrying out a cycle.

일반적인 공기조화기의 냉동싸이클은, 냉매를 압축시켜 주는 압축기와 고온.고압의 냉매를 응추기켜 주는 응축기와, 응축된 냉매를 저온.저압으로 변화시켜 주는 팽창밸브 및 열교환이 일어나는 증발기를 순환하게 된 구조이다.The refrigeration cycle of a general air conditioner includes a compressor that compresses refrigerant, a condenser that condenses high-temperature and high-pressure refrigerant, an expansion valve that converts the condensed refrigerant to low-temperature and low pressure, and an evaporator where heat exchange takes place. Structure.

이러한 종래의 기술은, 제1도 및 제2도에서와 같이 냉방을 수행하는 과정에서 응축기(1)로부터 나오게 되는 고온.고압의 냉매가 분배기(2)를 거쳐 곧바로 모세관(3)을 통과하여 증발기(4)에서 열교환을 하게 되었으므로, 고압으로 큰 직경을 흐르던 냉매가 급격히 축소된 모세관로 상으로 진입되는 과정에서 유체저항이 발생하게 되었다.In this conventional technique, as shown in FIG. 1 and FIG. 2, the high temperature and high pressure refrigerant, which is discharged from the condenser 1 in the course of cooling, passes through the capillary tube 3 directly through the distributor 2 to the evaporator. Since heat exchange was carried out in (4), fluid resistance occurred in the process of entering a large capillary channel with a rapidly reduced refrigerant flowing through a large diameter.

이에 의하여, 유체손실이 발생되고 냉매의 순환이 원할히 이루어지지 않으므로써 냉방효율이 저하되는 문제점이 있었다.As a result, there is a problem that the cooling efficiency is lowered because the fluid loss is generated and the circulation of the refrigerant is not made smoothly.

본 고안은 상기와 같은 문제점을 감안하여 안출한 것으로써, 본 고안의 목적은 냉매순환 과정중 응축효율을 향상시켜 냉방효과를 극대화 시킬 수 있는 공기조화기의 냉매순화구조를 제공함에 있다.The present invention has been made in view of the above problems, an object of the present invention is to provide a refrigerant purifying structure of the air conditioner that can maximize the cooling effect by improving the condensation efficiency during the refrigerant circulation process.

이러한 본 고안은, 응축기를 통과하는 고온.고압의 냉매가 모세관으로 유입되기 이전에 증발기를 거치고, 이 증발기에 의해 생성된 응축수에 의해 저온.저압으로 변화된 상태에서 상기 모세관을 통해 증발기로 공급되게 함에 따라, 냉각효율을 향상시키게 됨을 특징으로 한 것이다.The present invention allows the high temperature and high pressure refrigerant passing through the condenser to pass through the evaporator before being introduced into the capillary tube, and to be supplied to the evaporator through the capillary tube in a state of being changed to low temperature and low pressure by the condensed water generated by the evaporator. Therefore, it is characterized in that to improve the cooling efficiency.

도면 제3도 및 제4도는 본 고안의 실시예를 나타낸 것으로써, 제3도중 도면부호(10)은 열교환을 하게 되는 증발기이며, 이 증발기(10)에는 다수의 냉각파이프(11)가 부설되어 있다.3 and 4 illustrate an embodiment of the present invention, in FIG. 3, reference numeral 10 denotes an evaporator for heat exchange, and a plurality of cooling pipes 11 are attached to the evaporator 10. have.

상기 냉각파이프(11)의 유입구(12')(12)에는 모세관(20)이 연결되며, 각각의 토출구(13)(13')(13)측에는 콜렉타(30)가 연결되어 있다.The capillary tube 20 is connected to the inlets 12 'and 12 of the cooling pipe 11, and the collector 30 is connected to each of the discharge ports 13, 13' and 13 side.

그리고, 제4도에서와 같이 응축기(40)의 토출구측에 연결된 냉매파이프(41)는 상기 증발기(10)의 하부를 지나 분배기(50)에 연결되며, 이 분배기(50)를 통과한 냉매는 모세관(20)으로 보내지게 된다.Then, as shown in FIG. 4, the refrigerant pipe 41 connected to the discharge port side of the condenser 40 is connected to the distributor 50 through the lower part of the evaporator 10, and the refrigerant passing through the distributor 50 is To the capillary 20.

이때, 응축기(40)로부터 증발기(10)를 지나게 되는 냉매파이프(41)는 증발기(10)의 열교환 작용에 의해 생성되는 응축수를 활용할 수 있게 증발기의 하부측으로 부설하는 것이 바람직하다.At this time, the refrigerant pipe 41 passing through the evaporator 10 from the condenser 40 is preferably placed on the lower side of the evaporator so as to utilize the condensed water generated by the heat exchange action of the evaporator 10.

따라서, 상기와 같은 본 고안은 공조기의 구동이 시작되면 압축기(도시하지 않았음)의 작용에 의해 냉매가스를 고온.고압으로 압축하고 압축된 냉매는 응축기(40)를 통하여 방열작용을 하게 된다.Therefore, the present invention as described above, when the operation of the air conditioner starts to compress the refrigerant gas at a high temperature and high pressure by the action of a compressor (not shown), and the compressed refrigerant is radiated through the condenser 40.

이어서, 응축기(40)를 통과한 냉매는 증발기(10)의 하부로 배관된 냉매파이프(41)를 지나게 되므로써, 증발기와 이에 부설된 냉각파이프(11)의 열교환 작용에 의해 생성.집수되는 응축수가 상기 냉각파이프를 식혀 주게 된다.Subsequently, the refrigerant passing through the condenser 40 passes through the refrigerant pipe 41 piped to the lower part of the evaporator 10, whereby the condensed water generated and collected by the heat exchange action of the evaporator and the cooling pipe 11 attached thereto. The cooling pipe is cooled.

이에 의하여, 응축기(40)로부터 나오는 냉매는 모세관(20)에 유입되기 이전단계에서부터 현저히 낮은 온도와 압력으로 변화되고, 변화된 저온.저압 상태의 냉매가 분개기(50)를 거쳐 모세관(20)으로 보내지게 되는 것이다.As a result, the refrigerant from the condenser 40 is changed to a significantly low temperature and pressure from the step before entering the capillary 20, and the changed low-temperature / low pressure refrigerant passes through the respirator 50 to the capillary 20. Will be sent.

그러므로, 저온.저압의 냉매는 모세관(20)을 원활히 통과하게 됨과 아울러 증발기(10)에 부설된 냉각파이프(11)로 유입.순환되는 통상적인 순환을 하게 된다.Therefore, the low temperature and low pressure refrigerant passes smoothly through the capillary tube 20 and undergoes a normal circulation in which the coolant 11 is introduced and circulated to the cooling pipe 11 installed in the evaporator 10.

한편, 상기 작용중 응축기(40)를 통과한 냉매를 모세관(20)에 유입되기 전에 더욱 낮은 온도와 압력으로 응축시킴에따라, 고압의 냉매가 직경이 큰 관로에서 작은 직경의 관로로 흐르게 될 때 발생되는 유체손실을 축소시켜 주게 되며, 냉매액의 순환을 더욱 원활하게 하여 준다.Meanwhile, as the refrigerant passing through the condenser 40 is condensed at a lower temperature and pressure before flowing into the capillary tube 20 during the operation, when the high pressure refrigerant flows from the large diameter pipeline to the small diameter pipeline. It reduces the fluid loss generated and makes the circulation of refrigerant liquid more smooth.

또한, 상기한 작용은 증발기(10)의 열교환 작용에 의해 자연발생적으로 생성되는 응축수를 활용하게 됨으로써, 별도의 에어지원을 사용하지 않게 된다.In addition, the above action is to utilize the condensed water naturally generated by the heat exchange action of the evaporator 10, thereby avoiding the use of a separate air support.

이와같은 본 고안 실시예는, 냉매의 순환과정중 방열작용을 수행하는 응축기의 효율향상으로 전체적인 순환을 원활히 하게 됨으로써 냉각효과를 더욱 증대시킬 수 있는 효과가 있으며, 회수되는 응축수의 활용으로 인하여 에너지를 절감시킬 수 있는 경제적인 장점이 있는 것이다.Such an embodiment of the present invention, by improving the efficiency of the condenser to perform the heat dissipation during the circulation process of the refrigerant has an effect that can further increase the cooling effect, by utilizing the recovered condensate water energy There is an economic advantage that can be reduced.
