Description

실외기가 필요없는 자체 냉각식 에어콘Self cooling air conditioner without outdoor unit

본발명은 실내기 내부에 냉매를 냉각하는 장치를 구성하여 실외기가 필요없이 실내기 만으로 완전한 에어콘 작용이 이루어지는 에어콘에 관한 것으로, 특히 물과 공기를 동시에 이용하여 냉매를 냉각시킴으로써 냉각효율을 최대한 높일수 있도록 개량한 것이다.The present invention relates to an air conditioner that forms a device for cooling a refrigerant inside an indoor unit so that the air conditioner is completely operated only by the indoor unit without an outdoor unit. In particular, the present invention has been improved to maximize cooling efficiency by cooling a refrigerant using water and air simultaneously. will be.

실내기 자체에서 냉매의 냉각을 시킬수 있도록 한 에어콘은 본인의 선출원(특허출원 97-3394호의 다수)과 개발된바 있는데, 상기한 선출원의 구성에 의하면 냉매의 냉각 효율이 낮아서 많은양의 물이 연속으로 필요하여 물소비가 과다하였고 공기를 실내기 내부에서 계속 순환시켜야 함에따라 공기를 별도로 냉각시켜야 하는등 그에따른 구성이 복잡해지는 단점이 있으며, 물을 분사시킬때도 물이 적절하게 분사되지 못하여 냉각 효율이 떨어지는등 여러가지 폐단이 있었다.The air conditioner that allows cooling of the refrigerant in the indoor unit itself has been developed with its own prior application (many of patent applications 97-3394). According to the above-mentioned configuration, the cooling efficiency of the refrigerant is low, so that a large amount of water is continuously As the water consumption is excessive and the air must be continuously circulated inside the indoor unit, the air must be cooled separately, resulting in a complicated configuration.In addition, when the water is sprayed, the cooling efficiency is lowered because the water is not sprayed properly. There were various closures.

이에따른 본발명은 물과 공기를 동시에 이용하여 냉매를 식히되 공기는 실내의 공기를 유입하여 냉매를 냉각시킨 다음 외부로 배출되도록 함으로써, 냉각효율이 매우 뛰어남에 따른 에어콘 성능의 월등한 향상을 이룩하고 물공급이 거의 없이도 에어콘 작용이 정상적으로 이루어질수 있게 함을 목적으로 안출된 것이다.Accordingly, the present invention cools the refrigerant by using water and air at the same time, but the air enters the indoor air to cool the refrigerant and then discharges it to the outside, thereby achieving an excellent improvement of the air conditioner performance due to the excellent cooling efficiency. And it is devised for the purpose of allowing the air conditioner to work normally with little water supply.

한편 종래에도 실내의 공기를 빨아들여 냉매를 냉각시키는 에어콘이 있기는 하지만 이는 단순히 공기만으로 냉매를 냉각시키는 것이기 때문에 지름이 매우 큰 배기관을 사용하더라도 냉각 효율이 너무 낮아서 실용화지 못했던바, 본발명에서는 물과 공기를 동시에 적절히 이용하여 냉매를 냉각시킴으로써 실내기만으로 이루어지는 에어콘이 완벽한 성능을 발휘토록 개량 한 것이라 할 수 있다.On the other hand, although there are conventional air conditioners that suck air in the room to cool the refrigerant, this is simply to cool the refrigerant using only air, so even if a large diameter exhaust pipe is used, because the cooling efficiency is too low. By cooling the refrigerant by using the proper and air at the same time, it can be said that the air conditioner consisting only of the indoor unit is improved to show perfect performance.

”Shaped support plate 15 is formed and installed as a heat exchanger 5 divided into two, and a water spray plate 4 having a plurality of injection holes 10 is placed on the bottom of the heat exchanger 5, The connection pipe 17 of the water spray plate 4 is connected to the supply pipe 18 connected from the pump (1).

냉각케이스(7) 상부에는 약간의 간격을 두고 상부커버(19)를 설치하는데, 상부커버(19)의 중앙부에 배기공(20)을 형성한후 배기팬(21)을 설치하여 배기관(22)으로 에어콘(21) 외부(실외)로 공기가 배출되도록 하며, 상부커버(19) 앞쪽의 증발기(2)가 설치되는 부분에는 응축수유입공(23)을 형성하여 증발기(2)에서 발생하는 응축수가 냉각케이스(7) 내부로 유입되게 하였다.The upper cover 19 is installed on the upper part of the cooling case 7 with a slight gap. The exhaust pipe 20 is installed after the exhaust hole 20 is formed in the center of the upper cover 19. Air is discharged to the outside (outside) of the air conditioner 21, and a condensate inlet 23 is formed at the portion where the evaporator 2 in front of the upper cover 19 is installed to form condensate water generated in the evaporator 2. It was allowed to flow into the cooling case (7).

한편 냉매의 흐름은 제2도에 잘나타나 있듯이 콤푸레샤(24)에서 압된 냉매는 냉각케이스(7) 내부에 2개 설치된 열교환기(6)를 통과한후 모세관(25)을 거쳐 증발기(2)로 유입되게 하였고, 증발기(2)를 순환한 다음에는 다시 콤푸레샤(24)로 유입되게 하였다.Meanwhile, as shown in FIG. 2, the refrigerant flows through the heat exchanger 6 installed in the cooling case 7 and passes through the capillary tube 25 to the evaporator 2. After the evaporator (2) was circulated, it was introduced again into the compressor (24).

도면중 미설명된 부호 30은 냉방팬, 31은 전면카바이다.In the drawings, reference numeral 30 denotes a cooling fan and 31 a front cover.

상기한 본발명의 작용을 살펴본다.Look at the operation of the present invention described above.

최초 물탱크(6) 내부에 물을 채워둔 다음 에어콘(1)을 작동시키면, 콤푸레샤(24)에 의해 냉매가 열교환기(5)와 모세관(24) 및 증발기(2)를 통해 순환하는데, 콤푸레샤(24)에 의해 압송되는 냉매에는 상당한 열이 발생하므로 이를 열교환기(5)에서 어느 정도까지 식혀주어야 한다.After filling the water tank 6 first and operating the air conditioner 1, the compressor 24 circulates the refrigerant through the heat exchanger 5, the capillary tube 24, and the evaporator 2. Since the refrigerant pressurized by (24) generates considerable heat, it must be cooled to some extent in the heat exchanger (5).

열교환기(5)가 열을 식혀주는 과정을 자세히 살펴보면,Looking at the process of the heat exchanger (5) to cool the heat in detail,

냉매가 열교환기(5)를 통과하는 도중 물탱크(6)내의 물은 펌프(12)에 의해 물순환관(9) 및 물공급관(8)을 통해서 냉각케이스(7) 위쪽 내부로 유입되어 물분사판(4)의 연결관(17)으로 연결되므로 물은 물분사판(4)의 분사구멍(16)을 통해 열교환기(5)에 뿌려지면서 열교환기(5)내를 흐르는 냉매를 식혀주고 물은 다시 물탱크(6) 내부로 유입된다.While the refrigerant passes through the heat exchanger (5), the water in the water tank (6) is introduced into the upper portion of the cooling case (7) through the water circulation pipe (9) and the water supply pipe (8) by the pump (12). Since water is connected to the connecting pipe 17 of the swash plate 4, the water is sprayed into the heat exchanger 5 through the injection hole 16 of the water spray plate 4, cooling the refrigerant flowing in the heat exchanger 5, and the water is cooled. It is introduced again into the water tank (6).

상기한 물에 의한 열교환기(5) 냉각과정중 공기에 의한 냉각작용도 동시에 이루어지는데, 배기팬(21)이 에어콘(1)의 작용과 동시에 작용하므로 냉각케이스(7) 내부의 공기를 빨아들여 배기관(22)을 통해 실외로 배출시키는 것이고 냉각케이스(7)쪽으로 들어온 실내의 공기가 공기유입통로(14)를 통해 냉각케이스(7) 내부로 들어가는 것이다.In the cooling process of the heat exchanger (5) by water, the cooling operation by air is also performed at the same time. Since the exhaust fan (21) acts simultaneously with the action of the air conditioner (1), it sucks in the air inside the cooling case (7). It is to discharge to the outside through the exhaust pipe 22 and the indoor air entering the cooling case (7) is to enter the cooling case (7) through the air inlet passage (14).

냉각케이스(7) 내부를 아래에서 위로 흐르는 공기는 열교환기(5)의 열을 빼앗아갈 뿐아니라 아래로 흐르면서 더워진 물의 열을 빼앗아 배출시키므로 물은 계속 순환하더라도 온도가 일정온도 이상 되는 것을 억제하는 효과가 있다.The air flowing from the bottom to the top of the cooling case 7 not only takes away the heat of the heat exchanger 5, but also takes away the heat of the heated water as it flows down, thereby restraining the temperature from exceeding a certain temperature even though the water continues to circulate. It works.

또 본발명에서는 증발기(2)에서 발생하는 차가운 응축수도 물의 온도를 떨어뜨리는 중대한 요인이 되므로 냉각효율을 더욱 높이게 된다.In addition, in the present invention, the cold condensate generated in the evaporator 2 also becomes a significant factor to lower the temperature of the water, thereby further increasing the cooling efficiency.

본발명에 설치된 솔레노이드벨브(11)는 최초 물탱크(6)내에 물을 공급하기 위한 것이고 수위감지 및 배출관(10)은 에어콘(1)을 사용하지 않거나 이동시 물탱크(6)의 물을 배출시키는 것을 목적으로 구성된 것으로서, 물은 열교환기(5)를 식히는 과정에서 일정량 증발되어 배기관(22)으로 배출되고 증발기(2)에서는 응축수가 발생하므로 물탱크(6)내의 물은 수위변화가 없어서 물의 공급과 배출이 필요가 없게 되는 잇점이 있다.The solenoid valve 11 installed in the present invention is for supplying water in the first water tank 6, and the water level detection and discharge pipe 10 discharges water from the water tank 6 when the air conditioner 1 is not used or moves. It is configured for the purpose, the water is evaporated in a certain amount in the process of cooling the heat exchanger (5) is discharged to the exhaust pipe (22) and the condensed water is generated in the evaporator (2) water in the water tank (6) does not change the water level supply of water There is an advantage in that it does not need to be discharged.

하지만 실내온도가 비정상적으로 높게 상승하거나 응축수의 발생이 거의 없어 물탱크(6)의 물이 말라버리는등 간혹 있을지 모르는 이상 상태를 대비하기 위해 사용될 수도 있는데, 수위감지센서(13)에 의해 물탱크(6)내의 수위가 너무 낮은 것이 감지되면 솔레노이드밸브(11)에 의해 상수도물을 공급할 수 있으므로 상기한 비정상 상태에도 대처할 수도 있다.However, it may be used to prepare for abnormal conditions, such as an abnormally high indoor temperature or the occurrence of condensate, which causes the water in the water tank 6 to dry out, which may be caused by the water level sensor 13. 6) If it is detected that the water level is too low, the water supply can be supplied by the solenoid valve 11, so it can also cope with the above abnormal state.

한편 본발명의 구성중 냉각케이스(7)의 하단에 물탱크(6)를 형성하고 있으나 별개로 구성하여 결합시킬 수도 있고, 물탱크(6)에서 펌프(12)를 통해 물분사판(4)으로 연결되는 물의 순환라인을 냉각케이스(7) 내부에 내장시킬 수도 있다.Meanwhile, the water tank 6 is formed at the bottom of the cooling case 7 in the configuration of the present invention. The circulation line of the water to be connected may be embedded in the cooling case (7).

이상 설명한 바와같은 본발명은 에어콘(1)의 내부에 열교환기(5)를 설치하면서 물을 열교환기(5)에 분사시켜 열을 식혀주도록 하고, 아울러 열교환기(5)의 아래에서 위로 공기를 통과시킴으로써 열교환기(6)를 식히고 더워진 물을 다시 식혀주도록 구성한 것으로, 설치 및 이동이 편리하고 에어콘 구입시의 부담을 줄여주는 등의 기본적인 잇점을 충분히 누리면서 에어콘의 냉각작용을 원활하게 하여 실내기만으로 된 에어콘의 성능을 더욱 완벽히 할 수 있는 뛰어난 발명인 것이다.The present invention as described above, while installing the heat exchanger (5) inside the air conditioner (1) to spray the water to the heat exchanger (5) to cool the heat, and also to the air from below the heat exchanger (5) It is configured to cool the heat exchanger (6) by passing it through and to cool the heated water again.The indoor unit is smoothed by cooling the air conditioner while enjoying the basic advantages such as ease of installation and movement and reducing the burden of purchasing the air conditioner. It is an excellent invention that can make the performance of the air conditioner of the bay more perfect.
