Description

상온가압식 냉매 주입기Cold Pressure Injector

본 고안은 산업 전반에 다양한 용도로 사용되고 있는 냉매를 필요로 하는 대상물에 주입할 때 냉매저장 용기를 가열하지 않고, 상온에서 대상물의 응축기내로 냉매의 주입이 가능하게 한 상온 가압식 냉매 주입기에 관한 것이다.The present invention relates to a room temperature pressurized refrigerant injector that allows the refrigerant to be injected into the condenser of the object at room temperature without heating the refrigerant storage container when the refrigerant is injected into the object requiring the refrigerant, which is used for various purposes throughout the industry.

일반적으로 냉매는 불연성이고, 독성과 자극성이 없으며 열적, 화학적으로 안정되고 가격이 싼 이점과 각종 용도에 적합하여 산업 전반에 다양하게 사용되는 것으로서, 액체상태 또는 기체상태로 응축기내에서 일정압력으로 존재하게 되는데, 지금까지는 이러한 냉매를 냉장고, 냉동기, 에어컨 등의 필요로 하는 곳에 주입하기 위해서는 주입이 가능한 높은 압력을 갖도록 냉매 저장용기에 일정시간 가열을 하여, 용기의 압력을 상승 시킨 다음, 응축기내로 주입을 하게 되는바, 주입작업이 번잡하게 되고 전체 주입시간이 가열시간으로 인하여 장시간 소요되며, 가열시의 온도변화에 따라 주입되는 냉매량의 변동되는 등의 문제점이 있었다.Generally, refrigerants are non-flammable, non-toxic and non-irritating, thermally, chemically stable, inexpensive and suitable for various applications. They are used in various industries. They exist in the liquid or gas state at constant pressure in the condenser. Until now, in order to inject these refrigerants into the need of refrigerators, freezers, air conditioners, etc., they are heated in a refrigerant storage container for a certain time so as to have a high pressure that can be injected, and then the pressure of the container is raised, and then injected into the condenser. As a result, the injection operation is complicated and the entire injection time takes a long time due to the heating time, and there is a problem such that the amount of refrigerant injected is changed according to the temperature change during heating.

또한, 용기내의 압력이 낮은 동절기에는 가열시간이 더욱 길어지고 온도가 영하 10℃ 이하로 낮은 경우에는 용기내의 압력을 응축기내의 주입을 위한 주입압력까지 상승시키는 것은 불가능하여 주입작업을 할 수 없는 문제점과 가열장치로 인한 복잡한 구조와 무거운 중량 및 가격 또한 고가인 문제점이 있었다.In addition, in winter, when the pressure in the container is low, the heating time is longer, and when the temperature is lower than 10 ° C or lower, it is impossible to raise the pressure in the container to the injection pressure for injection into the condenser. The complicated structure and heavy weight and price due to the heating device also had problems.

본 고안은 이와 같은 지금까지의 문제점을 해결하기 위한 것으로, 주입되는 냉매의 압력을 압축실린더 내에서 소요압력으로 상승시킨 후, 상승된 일정압력 하에서 전자제어밸브의 개폐를 통해 냉매를 주입하는 것으로 이를 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.The present invention is to solve such problems until now, by increasing the pressure of the injected refrigerant to the required pressure in the compression cylinder, and injecting the refrigerant through the opening and closing of the electronic control valve under a certain constant pressure When described in detail with reference to the accompanying drawings as follows.

먼저 냉매를 주입하고자 하는 대상물 (냉동UNIT)을 진공상태로 만들기 위해 대상물의 저압 관로측 연결구에 본 장치의 저압측 호스를 연결하고, 내장된 진공펌프(⑪)를 이용하여 대상물의 관로를 대기압 이하의 진공 상태로 만든다. 이때 대상물의 진공도는 장치에 연결된 저압게이지(⑫)에 의해 확인할 수 있다. 대상물의 내부압력 상태가 필요한 진공도 까지 떨어지면 가압실린더(④)와 일체로 연결하여 제작, 설치된 압축실린더(⑤)를 이용하여 장치 내부로 냉매를 유입하는데, 이때 냉매용기(①)를 압축실린더(⑤)의 냉매유입관(③)측에 필터(②)를 통하여 연결한다. 냉매를 유입하기 위해서는 5bar이상의 공기압으로 가동되는 가압실린더(④)를 전, 후진 복동 운전 하므로써 이루어진다. 가압실린더(④)가 전자제어밸브(⑥)에 의해 전, 후진 하면 이에 직결 되어있는 압축실린더(⑤)의 한 쪽으로 냉매용기에 저장되어 있던 액상의 냉매가 인입 되는데, 이 때 관로상에 역지밸브를 설치하여 냉매의 토출이 일방향으로만 이루어질 수 있도록 하고, 토출관 측에는 압력스위치(⑧)를 부착하여 토출되는 냉매의 압력이 소요압력 이상에 도달하면 가압실린더(④)의 전자제어밸브(⑥)의 작동이 정지하여 가압실린더(④)의 동작이 정지되고, 주입실린더(⑩)의 전자제어밸브UNIT(⑨)이 작동되어 냉매의 주입이 시작되도록 전기회로를 구성한다. 이 때, 압축실린더(⑤)의 토출관에서 나오는 냉매의 압력은 압축실린더(⑤)의 동작에 따라 맥동하게 되므로 이러한 압력의 변화가 압력스위치(⑧)에 주는 영향을 최소화하기 위하여 압축실린더(⑤)와 압력스위치(⑧) 사이에 어큐물레이터(⑦)를 설치하여 압력의 변화량을 완충시킨다.First, connect the low pressure side hose of the device to the low pressure pipe side connector of the object in order to make the object (freezing unit) to be injected into the vacuum state, and use the built-in vacuum pump to keep the object pipe below atmospheric pressure. Let's make a vacuum. At this time, the degree of vacuum of the object can be confirmed by a low pressure gauge (⑫) connected to the device. When the internal pressure of the object falls to the required degree of vacuum, the refrigerant is introduced into the device by using a compression cylinder (⑤) which is manufactured and installed by integrally connecting with the pressure cylinder (④). At this time, the refrigerant container (①) is compressed into the compression cylinder (⑤). ) Is connected to the refrigerant inlet pipe (③) side through the filter (②). In order to introduce refrigerant, pressurized cylinder (④) operated at air pressure of 5 bar or more is performed by forward and reverse double acting operation. When the pressure cylinder (④) moves forward or backward by the solenoid control valve (⑥), the liquid refrigerant stored in the refrigerant container flows into one side of the compression cylinder (⑤) directly connected to the check valve. To ensure that the refrigerant is discharged in only one direction, and a pressure switch (8) is attached to the discharge tube side, and when the pressure of the discharged refrigerant reaches more than the required pressure, the electronic control valve (⑥) of the pressure cylinder (④) The operation of the pressure cylinder (④) is stopped, the operation of the injection cylinder (⑩) of the electronic control valve unit (⑨) is activated to configure the electric circuit to start the injection of the refrigerant. At this time, the pressure of the refrigerant from the discharge tube of the compression cylinder (⑤) is pulsated according to the operation of the compression cylinder (⑤), so to minimize the effect of such a change of pressure on the pressure switch (⑧) ), The accumulator (⑦) is installed between the pressure switch (⑧) and the pressure change buffer.

주입실린더(⑩)의 토출관에는 냉매의 토출이 일방향으로 이루어지도록 네개의 전자제어밸브UNIT(⑨)를 설치한다. 네개의 전자제어밸브는 인입과 토출을 담당하는 밸브 두개씩 한 조를 이루어, 각 조가 번갈아 가며 주입실린더에 냉매를 채우고, 빼낼 수 있도록 작동한다. 즉, 그림에서 a그룹의 밸브가 열리면 주입실린더의 피스톤이 제2 도의 상 방향으로 전진하면서 냉매를 피스톤 하부공간으로 빨아들이고, 상부에 채워져있던 냉매를 고압관로 측으로 토출해 낸다. 피스톤이 전진하면 전진위치의 끝에 설치된 리드 스위치가 피스톤에 감겨있는 자석을 감지하여 a그룹밸브를 닫고, b그룹밸브를 열어 줌으로써 주입실린더의 피스톤이 아래방향으로 움직이면서 전술의 동작을 동일하게 반복, 수행하게 된다.In the discharge tube of the injection cylinder, four solenoid valves UNIT 9 are provided to discharge the refrigerant in one direction. The four solenoid valves consist of two valves, one for the inlet and the other for the discharge, so that each of the valves alternately fills and removes the refrigerant in the injection cylinder. That is, when the valve of group a is opened in the figure, the piston of the injection cylinder moves forward in the upper direction of FIG. 2 to suck the refrigerant into the lower space of the piston, and discharges the refrigerant filled in the upper side to the high pressure pipe side. When the piston moves forward, the reed switch installed at the end of the forward position detects the magnet wound on the piston, closes the a group valve, and opens the b group valve to move the piston of the injection cylinder downward and repeat the above operation. Done.

한편, 토출되는 냉매의 주입량은 제어판에서 설정한 주입량의 십단위 숫자와 피스톤이 이동해서 리드스위치를 감지한 횟수가 같아지는 순간에 전자제어밸브UNIT(⑨)를 모두 닫아 줌으로써 정량이 주입될 수 있도록 주입실린더의 내부 용적을 냉매 10g이 수용될 수 있도록 제작하였다.On the other hand, the injected amount of refrigerant is discharged by closing all the electronic control valve UNIT (⑨) at the same time the number of tens of the injection amount set on the control panel and the number of times the piston is moved to detect the reed switch so that the quantity can be injected. The internal volume of the injection cylinder was manufactured to accommodate 10 g of refrigerant.

이와 같은 구성의 본 고안은 주입되는 냉매를 가열하지 않고, 압축실린더(⑤) 내에서 소요압력으로 상승시켜 냉매를 주입 하므로써 냉매를 신속하고도 간편하게 주입할 수 있어, 주입시간의 단축효과를 얻을 수 있을 뿐만 아니라, 10g 이내의 오차범위 내에서 정량주입이 가능하고, 영하의 온도에서도 작동할 수 있는 등 매우 지대한 효과를 제공하게 되는 것이다.The present invention of such a configuration allows the refrigerant to be injected quickly and simply by raising the required pressure in the compression cylinder (⑤) without heating the refrigerant to be injected, thereby achieving a shortening effect of the injection time. In addition, it is possible to provide quantitative injection within an error range within 10 g, and to operate at sub-zero temperatures, thereby providing a very profound effect.
