본 발명은 냉동기의 수액기 겸용 액분리식 열교환기에 관한 것으로, 특히 냉매시스템의 부품간소화로 냉동기의 크기를 축소함은 물론 냉동효과도 증대되게 할 목적으로 발명된 것이다.The present invention relates to a liquid-separated heat exchanger for both a liquid receiver and a refrigerator of the refrigerator. In particular, the present invention has been invented for the purpose of reducing the size of the refrigerator as well as increasing the freezing effect by simplifying components of the refrigerant system.

종래의 냉동시에 있어서의 냉매 싸이클을 살펴보면 도면 제 1 도에서와 같이 압축기(10)로부터 응축기(20)와 수액기(30) 및 열교환기(40)를 거쳐 증발기(50)를 통해 다시 열교환기(40)를 지나 액분리기(60)를 걸쳐 압축기(10)로 흡입되는 배관회로도를 가지게 한 것으로 수액기(30)는 냉매액을 저장하기 위해 필요하며, 액분리기(60)는 압축기(10)의 액백(back)을 방지하기 위함이며, 열교환기(40)는 과냉각도, 과열도를 조절하여 냉동효과를 증대시키기 위한 목적으로 각각 연결설치되었던 것이다.Referring to the refrigerant cycle in the conventional refrigeration, as shown in FIG. 1, the heat exchanger is again returned from the compressor 10 through the condenser 20, the receiver 30, and the heat exchanger 40 through the evaporator 50. It has a piping circuit diagram drawn through the liquid separator 60 through the liquid separator 60 through the 40, the fluid receiver 30 is required to store the refrigerant liquid, the liquid separator 60 is the compressor 10 In order to prevent the back of the (back), the heat exchanger 40 was installed to each of the purpose for increasing the refrigeration effect by adjusting the degree of supercooling, superheating.

따라서 냉동기의 크기가 자연적으로 크게 구성되어 질 수밖에 없으며, 증발기에 증발되지 않은 냉매액이 유입되면 자연증발시키는 방식으로 완전한 증발이 될 수 없으며, 또한 냉매의 유동이 불규칙적인 등의 단점이 있었다.Therefore, the size of the freezer must be naturally large, and when the refrigerant liquid not evaporated enters the evaporator, it cannot be completely evaporated by the natural evaporation method, and the flow of the refrigerant is irregular.

따라서 본 발명에서는 수액기, 액분리기 및 열교환기 각각의 기능을 별도로 발휘하게 한 것을 한 부품으로 하여 냉동기의 크기를 소형화할 수 있음은 물론 증발기에서 완전히 증발되지 않은 냉매액의 유입시 하부냉매액으로 강제증발시킬 수 있으며, 냉매의 유동을 고르게 할 수 있도록 하여 냉동효과가 증대되게 할 목적으로 수액기의 상부 내면에 액분리기를 내장하여 저압의 액분리기와 고압의 수액기에 의해 열교환기의 기능도 하게 구성한 것이다.Therefore, in the present invention, the size of the freezer can be miniaturized by using one part to separately perform the functions of the receiver, the liquid separator, and the heat exchanger, as well as the lower refrigerant liquid when the refrigerant liquid is not completely evaporated from the evaporator. It can be forcibly evaporated, and the refrigerant can be evenly flowed so that the freezing effect is increased. A liquid separator is built into the upper inner surface of the receiver to enable the function of the heat exchanger by a low pressure liquid separator and a high pressure receiver. It is made up.

이하에서 이를 첨부도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.

냉동기의 수액기 겸용 액분리식 열교환기를 구성함에 있어서, 상부에 응축기(20)로부터 입구(21)를 가지며, 하부에는 증발기로의 출구(22)를 가지는 고압상태의 수액기(1)와 상기 수액기(1) 내부의 상면에 부착설치되는 보다 작은크기의 액분리기(2) 상면엔느 증발기(50)로부터의 입구(51)와 압축기로의 출구(52)를 가지는 저압상태의 액분리기(2)가 내장된 구성으로써, 이때 출구는 액분리기(2) 내부에서 U형 트랩(3)상으로 구성되어 그 내장개구단부(31)가 액분리기(2)의 중심에 있게 위치되며, 절곡부(32) 중앙저부에는 오일리턴홀(33)을 가지며, 개구단부(31)보다 높은 위치의 압축기측으로의 출구(52)에는 균형홀(34)이 천공된 구조이다.In constructing the liquid separator-type heat exchanger for both the refrigerator and the receiver, the receiver 1 and the fluid of the high pressure state having the inlet 21 from the condenser 20 at the upper part and the outlet 22 to the evaporator at the lower part thereof. Smaller size liquid separator (2) attached to the upper surface inside the machine (1). Low pressure liquid separator (2) having an inlet (51) from the upper surface of the evaporator (50) and an outlet (52) to the compressor. ), The outlet is configured on the U-shaped trap (3) inside the liquid separator (2) so that the built-in opening 31 is located in the center of the liquid separator (2), the bent portion ( 32) An oil return hole 33 is provided at the center bottom, and a balance hole 34 is drilled at the outlet 52 toward the compressor at a position higher than the opening end 31.

이상과 같이 구성된 본 발명의 작용효과를 살펴보면 도면 제 2 도 및 제 3 도에서와 같이 냉동운전시 압축기(10)로부터 응축기(20)를 지난 응축냉매가 수액기(1)의 입구(21)로 유입되어 하부출구(22)를 지나 팽창변을 통해 증발기(50)로 간다. 이때 응축된 냉매는 액분리기(2)의 저압측과 열교환을 하고, 냉매액이 쉽게 팽창될 수 있도록 온도가 저하되어 팽창변을 통하여 유입된다. 이렇게 증발작용을 한후 내장설치된 액분리기(2)의 입구(51)로 유입된다.Referring to the operation and effect of the present invention configured as described above 2 and 3 as shown in Figure 2 during the refrigeration operation from the compressor 10 to the inlet 21 of the condenser refrigerant passing the condenser 20 after the condenser It enters and passes through the lower outlet 22 to the evaporator 50 through the expansion valve. At this time, the condensed refrigerant exchanges heat with the low pressure side of the liquid separator 2, and the temperature decreases so that the refrigerant liquid can be easily expanded and is introduced through the expansion valve. After the evaporation effect is so introduced into the inlet 51 of the liquid separator (2) installed.

이렇게 완전히 증발된 냉매가스는 냉매배관중의 윤활유와 함께 수액기(1)에 내장된 액분리기(2)로 유입되어 균형홀(34)에서 윤활유의 양을 조절하여 출구(52)를 통해 압축기로 유입된다.The refrigerant gas thus completely evaporated flows into the liquid separator 2 embedded in the receiver 1 together with the lubricating oil in the refrigerant pipe and adjusts the amount of lubricating oil in the balance hole 34 to the compressor through the outlet 52. Inflow.

이때, 증발이 완전하지 못해 증발기로부터 유입된 냉매가스는 수액기(1)로 유입되는 고압의 냉매액과 열교환되어 강제증발 되므로써 압축기(10)의 액백을 미연에 방지시킬 수 있다. 그리고 냉매액(고압측)의 유동이 심하게 되면 수액기(1)로부터 증발기(50)로 유입되는 냉매량이 일정하지 못해 팽변면이 그 기능을 발휘하지 못하게 되는데, 본 발명에서는 수액기(1) 내부에 액분리기(2)가 설치되므로 그 불균형한 유동을 막아 안정되게 해준다. 그리고 U형 트랩(3)의 저부에 오일리턴 홀(33)을 통하여 오일을 회수시키는 작용을 한다.At this time, the refrigerant gas introduced from the evaporator because the evaporation is not complete is heat-exchanged with the high-pressure refrigerant liquid flowing into the receiver 1 is forced evaporation, it is possible to prevent the liquid back of the compressor (10) in advance. When the flow of the refrigerant liquid (high pressure side) becomes severe, the amount of refrigerant flowing into the evaporator 50 from the receiver 1 is not constant, so that the bulge surface does not exhibit its function. In the present invention, the inside of the receiver 1 The liquid separator 2 is installed in the chamber, thereby preventing its unbalanced flow and making it stable. The oil is recovered through the oil return hole 33 at the bottom of the U-shaped trap 3.

이상과 같이 구성되고 작용되는 본 발명은 종래의 냉동기 시스템에 있어서 수액기와 열교환기 및 액분리기의 세부분을 통합하여 1개의 부품으로 축소시킴으로써 냉동기를 소형화시킬 수 있으며, 강제증발 방식으로 완전한 증발을 유도하며, 냉매의 불규칙적인 유동을 없애주는 등의 효과를 기대할 수 있는 발명인 것이다.The present invention constructed and operated as described above can reduce the size of the refrigerator by integrating the details of the receiver, the heat exchanger and the liquid separator into one part in the conventional refrigerator system, and induce a complete evaporation by a forced evaporation method. And, it is an invention that can expect the effect of eliminating the irregular flow of the refrigerant.
