이하, 첨부도면을 참조하여 본 발명의 실시례에 관하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도시된 바와 같이, 본 발명에 의한 윤활유 분리장치(100)는 내부에 윤활유 및 냉매의 수용공간이 형성된 본체(104)와; 그 본체(104)에 형성된 복수개의 혼합유 유입유로(101)와; 복수개의 혼합유 유입유로(101)에 연결되어 유입된 혼합유를 통합하는 통합유로(110)와; 본체(104)의 내부 수용공간을 혼합유 수용공간(A)과 냉매 및 윤활유 수용공간(B)으로 격리시키도록 장착된 분리 필터(103)와; 혼합유 수용공간(A)에 혼합유를 토출하도록 통합유로(110)의 단부에 형성된 혼합유 토출구(111)와; 냉매 및 윤활유 수용공간(B)으로부터 외부를 향하여 본체(104) 상부에 형성된 냉매 토출유로(102)와; 냉매 및 윤활유 수용공간(B)으로부터 외부를 향하여 본체(104)의 하부에 형성된 윤활유 토출유로(108)를; 포함하여 구성된다.As shown, the lubricating oil separating apparatus 100 according to the present invention includes a main body 104 formed therein the receiving space of the lubricating oil and the refrigerant; A plurality of mixed oil inflow passages 101 formed in the main body 104; An integrated passage 110 connected to the plurality of mixed oil inflow passages 101 to integrate the mixed oils introduced therein; A separation filter 103 mounted to isolate the inner accommodating space of the main body 104 into the mixed oil accommodating space A and the refrigerant and lubricating oil accommodating space B; A mixed oil discharge port 111 formed at an end of the integrated flow path 110 to discharge the mixed oil into the mixed oil containing space A; A refrigerant discharge passage 102 formed above the main body 104 from the refrigerant and the lubricant oil receiving space B to the outside; A lubricating oil discharge passage 108 formed in the lower portion of the main body 104 from the refrigerant and the lubricating oil receiving space B to the outside; It is configured to include.
즉, 복수개의 압축기(1)로부터 토출된 혼합유가 복수개의 유입유로(101)를 통해 하나의 수용공간을 형성하는 본체(104) 내부로 유입되어 분리 필터(103) 및 토출유로(102,108)에 의해 한번에 냉매와 윤활유로 분리 및 토출되도록 하는 구조를 취함으로써, 구성요소가 단순하고, 용량의 제한이 심하지 않으며, 복수개의 압축기에 대한 윤활유 분리 기능을 수행할 수 있는 구조가 되므로, 제조의 단순화, 비용 절감을 꾀할 수 있는 것이다.That is, the mixed oil discharged from the plurality of compressors 1 flows into the main body 104 forming one accommodation space through the plurality of inflow passages 101 and is separated by the separation filter 103 and the discharge passages 102 and 108. By taking a structure that separates and discharges the refrigerant and the lubricant at one time, the components are simple, the capacity is not severely limited, and the structure that can perform the lubricant separation function for a plurality of compressors is simplified. The savings can be made.
여기서, 분리 필터(103)는 메쉬 페드(mesh pad)에 의해 구성하는 것이 구성의 단순화 측면에서 바람직하다.Here, the separation filter 103 is preferably constituted by a mesh pad in terms of simplification of the configuration.
또한, 분리 필터(103)는 본체(104) 내부의 수용공간을 혼합유 수용공간(A)과냉매 및 윤활유 수용공간(B)으로 격리시키도록 장착되는 것이면 어떠한 구조를 취하든 관계없으나, 도 4에 도시된 바와 같이 본체(104)가 좌우방향으로 긴 구조인 저장탱크 구조를 취하는 경우에는 다음과 같은 구조를 취하는 것이 바람직하다.In addition, the separation filter 103 may be any structure as long as it is mounted to isolate the accommodating space inside the main body 104 into the mixed oil accommodating space (A) and the refrigerant and lubricating oil accommodating space (B). As shown in the figure, when the main body 104 takes a storage tank structure having a long structure in the horizontal direction, it is preferable to take the following structure.
즉, 분리 필터(103)는 수직하게 2개가 형성되어 본체(104) 내부의 수용공간을 3개의 공간으로 구획하는데, 냉매 및 윤활유 수용공간(B)은 그 3개의 수용공간 중 중앙에 위치하게 되고, 혼합유 수용공간(A)은 냉매 및 윤활유 수용공간(B)의 양측에 위치하게 되며, 혼합유 토출구(111)는 본체(104)의 내부 측면(105)에 인접하여 형성하는 것이다.That is, two separation filters 103 are formed vertically to partition the receiving space inside the main body 104 into three spaces, and the refrigerant and lubricant receiving space B are located at the center of the three receiving spaces. The mixed oil receiving space A is positioned at both sides of the refrigerant and the lubricating oil receiving space B, and the mixed oil discharge port 111 is formed adjacent to the inner side surface 105 of the main body 104.
이와 같은 구조를 취할 경우, 토출구(111)를 통해 토출된 혼합유는 본체 내부의 측면(105)에 충돌을 일으킨 후, 분리 필터(103)를 향하게 되므로, 그 흐름의 원활성 및 분리의 용이성 측면에서 보다 효과적이라 할 수 있다.In this structure, since the mixed oil discharged through the discharge port 111 collides with the side surface 105 inside the main body and then faces the separation filter 103, the smoothness of the flow and the ease of separation More effective at
이러한 본체의 내부 측면(105)이 내측으로 오목한 완곡면인 구성을 취할 경우, 상기와 같은 효과를 더욱 기대할 수 있다.When the inner side surface 105 of the main body has a concave curved surface inwardly, the above effects can be expected more.
또한, 냉매와 윤활유의 분리를 더욱 촉진하기 위해 본체(104)의 내부에는 윤활유 가열용 히터(107,109)가 더 포함되는 것이 바람직하다.In addition, in order to further facilitate the separation of the refrigerant and the lubricant, the inside of the main body 104 may further include a heater for heating the lubricant oil 107, 109.
이하, 본 발명에 의한 윤활유 분리장치가 적용된 냉장기기의 동작에 관하여 설명한다.Hereinafter, the operation of the refrigerating machine to which the lubricating oil separation device according to the present invention is applied will be described.
열교환기(미도시)로부터 유입되는 냉매는 그 흐름을 제어하기 위한 밸브(17)를 통해 석션 헤더(suction header : 13)로 유입되고, 그 석션 헤더(13)로부터 복수개의 분기유로 및 석션 필터(suction filter)를 통해 분기되어 각각의 압축기(1)로 유입된다.The refrigerant flowing from the heat exchanger (not shown) flows into the suction header 13 through a valve 17 for controlling the flow thereof, and from the suction header 13 a plurality of branch flow paths and suction filters ( branched through a suction filter and introduced into each compressor 1.
압축기 내의 압력은 오일 프레셔 게이지(oil pressure gauge : 10)를 통해 확인할 수 있으며, 그 압력의 정도에 따라 압축기 제어부(oil pressure controller : 9)가 압축기의 구동을 제어한다.The pressure in the compressor can be checked through an oil pressure gauge (10), and the compressor controller (oil pressure controller) 9 controls the driving of the compressor according to the pressure.
한편, 압축기의 윤활한 구동을 위해 별도의 윤활 장치가 마련되는데, 윤활유 저장탱크(3)에 저장된 윤활유는 윤활유 공급유로(4)를 통해 복수개의 분기유로(4a, 4b, 4c, 4d)로 분기된 후, 필터-드라이어(filter-dryer : 5), 사이트 글래스(sight glass : 29) 및 오일 레벨 레귤레이터(oil level regulator : 6)를 통해 압축기(1)로 공급된다.On the other hand, a separate lubrication device is provided for the lubricated driving of the compressor, the lubricating oil stored in the lubricating oil storage tank (3) is branched into a plurality of branching passages (4a, 4b, 4c, 4d) through the lubricating oil supply passage (4) Then, it is supplied to the compressor 1 through a filter-dryer 5, a sight glass 29 and an oil level regulator 6.
공급된 윤활유는 압축기(1) 내에서 윤활 작용을 하는 도중 냉매와 혼합되어 혼합유를 형성하고, 이러한 혼합유는 윤활유 분리기(oil seperator : 100)에서 냉매와 윤활유로 분리된다.The supplied lubricating oil is mixed with the refrigerant to form a mixed oil during lubrication in the compressor 1, and the mixed oil is separated into a refrigerant and a lubricating oil in an oil seperator 100.
혼합유 유입유로(101)를 통해 본체(104) 내부로 유입된 혼합유는 통합유로(110)에서 통합된 후, 토출구(111)를 통해 혼합유 수용공간(A)으로 토출되는데, 이때 토출된 혼합유는 본체 내부 측면(105)에 충돌되어 냉매는 상측으로 냉매가 혼합된 윤활유는 하측으로 이동한다.The mixed oil introduced into the main body 104 through the mixed oil inflow passage 101 is integrated in the integrated passage 110 and then discharged into the mixed oil accommodation space A through the discharge port 111. The mixed oil impinges on the inner side surface 105 of the main body so that the refrigerant moves upward and the lubricant mixed with the refrigerant moves downward.
상부의 냉매는 필터(103)를 그대로 통과하고, 하부의 혼합유는 필터(103)를 통과하면서 냉매와 윤활유로 분리되는데, 이와 같이 냉매 및 윤활유 수용공간(B)에 도달한 냉매 및 윤활유는 각각 냉매 토출유로(102) 및 윤활유 토출유로(108)를 통해 토출된다.The upper refrigerant passes through the filter 103 as it is, and the lower mixed oil passes through the filter 103 and is separated into a refrigerant and a lubricating oil. Thus, the refrigerant and the lubricating oil reaching the refrigerant and the lubricating oil accommodating space B are respectively The refrigerant is discharged through the discharge passage 102 and the lubricating oil discharge passage 108.
토출된 냉매의 일부는 바이-패스 솔레노이드(by-pass solenoid)를 통해 압축기(1)로 재유입되고, 일부는 팽창 밸브(30)를 통과하면서 팽창하여, 도중에 압력을 확인하고 제어하기 위한 고압 센서(high pressure sensor : 23) 및 고압 게이지(high pressure gauge)가 설치된 디스차지 헤더(discharge header : 7)를 통해 응축기(8)로 공급된다.Part of the discharged refrigerant is re-introduced into the compressor 1 through a by-pass solenoid, and part of the refrigerant is expanded while passing through the expansion valve 30 to check and control the pressure on the way. A high pressure sensor 23 and a high pressure gauge are supplied to the condenser 8 through a discharge header 7 installed therein.
응축기(8)에서 응축된 냉매는 안전 밸브(19)를 통해 응축기를 통과하지 않고 직접 유입된 고압 냉매와 리시버 탱크(receiver tank : 25)에서 합류한 후, 액냉매 사이트 글래스(liquid sight glass), 필터-드라이어(filter-dryer : 27) 및 토출밸브(28)를 통과하여 다시 열교환기(미도시)로 공급된다.The refrigerant condensed in the condenser (8) is combined with the high pressure refrigerant directly introduced into the receiver tank (25) without passing through the condenser through the safety valve (19), the liquid sight glass (liquid sight glass), The filter-dryer 27 and the discharge valve 28 are supplied to the heat exchanger (not shown).
토출된 윤활유는 별도의 저장탱크에 저장되지 않고, 다시 윤활유 공급유로(4)를 통해 복수개의 분기유로(4a, 4b, 4c, 4d)로 분기된 후, 필터-드라이어(5), 사이트 글래스(29) 및 오일 레벨 레귤레이터(6)를 통해 압축기(1)로 공급된다.The discharged lubricating oil is not stored in a separate storage tank, but is branched back into the plurality of branching passages 4a, 4b, 4c, and 4d through the lubricating oil supply passage 4, and then the filter-dryer 5 and the sight glass ( 29) and to the compressor 1 via the oil level regulator 6.
본 발명은 구성요소가 단순하고, 용량의 제한이 심하지 않으며, 복수개의 압축기에 대한 윤활유 분리 기능을 수행할 수 있도록 함으로써, 제조의 단순화, 비용 절감을 꾀할 수 있도록 하는 냉장기기의 압축기용 윤활유 분리 장치를 제공한다.The present invention provides a compressor lubricating oil separating device for a refrigeration machine that can simplify the manufacturing and reduce the cost by allowing the components to be simple, not limited in capacity, and able to perform lubricating oil separating functions for a plurality of compressors. To provide.
