본 고안은 냉각장치에 관한 것으로서, 특히 봉입 냉매의 누설유무를 감시할 수 있도록 설치되며, 그 누설 유무를 알리는 냉매 누설 감시장치를 갖는 냉각장치에 관한 것이다.The present invention relates to a cooling device, and more particularly, to a cooling device having a refrigerant leakage monitoring device that is installed to monitor the presence or absence of leakage of the sealed refrigerant and informs the presence or absence of the leakage.

일반적으로 냉각장치에는 냉장고, 에어콘(Air Conditioner)등이 있고, 이러한 냉각장치는 압축기, 응축기, 증발기, 모세관 등으로 구성되어 냉매를 유동회로 상에서 압축 및 증발시켜 공기의 온도, 습도등을 제어하는데 이용된다.Generally, a cooling device includes a refrigerator and an air conditioner, and the cooling device is composed of a compressor, a condenser, an evaporator, and a capillary tube, and is used to control the temperature and humidity of the air by compressing and evaporating the refrigerant in a flow circuit. do.

상기 냉각장치에 있어서, 부족한 냉매의 량은 냉방 효율감소와 냉각장치의 수명을 단축시킨다. 즉, 냉매의 누설은 냉각이 잘 되지 않으므로 냉각 효율을 낮추며, 효율이 낮아짐으로 설정온도까지 낮추기 위해 모터를 최대로 가동하여 볼 필요한 전력을 낭비할 뿐만 아니라, 압축기의 수명을 단축시킨다.In the above cooling apparatus, the amount of the insufficient refrigerant shortens the cooling efficiency and shortens the life of the cooling apparatus. That is, the leakage of the refrigerant is not cooled well, so the cooling efficiency is lowered, and the efficiency is lowered, and not only wastes the power required to operate the motor at maximum to lower the set temperature, but also shortens the life of the compressor.

종래에는 상술한 냉매의 누설을 실 사용자가 직접 확인할 수 있는 방법은 별도의 냉매량 및 압력을 측정기구를 이용하여 냉매량을 측정하는 방법 외에는 좋은 방법이 없었다. 더욱이, 운행중에는 냉매의 성질상 무색 무취이므로 냉매의 누설을 실 사용자가 확인 할 수 없어 많은 문제점이 발생되었다.In the related art, there is no method other than the method of measuring the amount of refrigerant using a separate measuring amount and pressure of the refrigerant to measure the leakage of the refrigerant directly. Moreover, since the colorless and odorless nature of the refrigerant during operation, many problems occurred because the leakage of the refrigerant can not be confirmed by the actual user.

따라서 본 고안의 목적은 냉매 누설 여부를 실 사용자가 쉽게 알 수 있도록 하며, 실내 실외의 온도에 따라 냉매량 차이를 감지하여 누설여부를 정확히 판단하여 통지할 수 있는 냉매 감시장치를 제공하는데 있다.Accordingly, an object of the present invention is to provide a refrigerant monitoring device that enables a real user to easily know whether a refrigerant leaks, and detects a difference in refrigerant amount according to an indoor / outdoor temperature to accurately determine whether the refrigerant is leaked.

Characterized in that.

그리고 상기 냉매와 첩촉하는 부분의 피스톤에 설치되어 냉매의 압력을 측정하는 압력센서와, 이 압력센서에 연결되어 센서의 감지사항을 알리는 알림수단과, 이 알림수단과 압력센서 사이에 설치되어 압력센서의 감지 사항을 근거로 상기 알림수단에 지령을 내리는 제어수단을 더 구비하는 것을 특징으로 한다.And a pressure sensor installed on the piston in contact with the refrigerant to measure the pressure of the refrigerant, a notification means connected to the pressure sensor to inform the sensor of the detection, and installed between the notification means and the pressure sensor. The control means for giving a command to the notification means on the basis of the detected matters is characterized in that it further comprises.

이하 첨부된 도면을 참조하면서, 본 고안의 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 고안에 따른 냉매량 감시장치의 주요부를 도시한 정면도이다. 도시된 바와 같이, 투명한 재질의 튜브(10)의 일단을 조임볼트(20)를 이용하여 냉매가 흐르는 파이프(30)에 연결하고 그튜브(10)내부에는 이 튜브의 내 주면을 따라 이동하는 피스톤(40)이 설치되어 있다. 이 피스톤(40)은 스프링(50)에 의하여 냉매의 압력에 대항하도록 탄성 바이어스되어 있다. 그리고 상기 튜브(10)의 외 주면에 눈금(11)이 표시되어 있어, 상기 피스톤(40)이 상기 스프링(40)의 탄성력과 냉매의 압력에 따라 튜브(10)내에서 이동하여, 그 힘들이 일치하는 위치에서 피스톤(40)이 정지함으로 눈금을 통하여 현재 냉매의 압력을 측정할 수 있다.1 is a front view showing the main part of the refrigerant amount monitoring device according to the present invention. As shown in the drawing, one end of the transparent tube 10 is connected to the pipe 30 through which the refrigerant flows using the fastening bolt 20, and the inside of the tube 10 moves along the inner circumferential surface of the tube. 40 is provided. The piston 40 is elastically biased to counteract the pressure of the refrigerant by the spring 50. And the scale 11 is displayed on the outer peripheral surface of the tube 10, the piston 40 moves in the tube 10 in accordance with the elastic force of the spring 40 and the pressure of the refrigerant, the force is As the piston 40 stops at the corresponding position, the pressure of the present refrigerant can be measured through the scale.

상기 피스톤(40)에는 압력센서(60)가 부착되어 있으며, 이 압력센서(60)는 전선(61)으로 후술하는 제어기에 연결되어 있다. 이 압력센서(60)는 제2도에 도시된 바와 같이, 냉매의 압력이 낮아지면 센서의 저항값도 낮아짐으로, 소정의 압력에서 후술하는 부져를 작동시킬 수 있도록 하였다. 즉, 제3도는 본 고안에 따른 냉매누설 감지장치에 연결되는 제어기의 주요부를 도시한 회로도이다. 도시된 바와 같이, 제어기(70)에는 상기 피스톤에 설치된 압력센서(60)와 실내 온도센서(62)실외 온도센서(62)가 설치되어 있으며, 이들 센서 데이타를 근거로 발진기(71)는 부져(72)에 신호를 보내어 소리를 발생시킨다.A pressure sensor 60 is attached to the piston 40, and the pressure sensor 60 is connected to a controller described later by an electric wire 61. As shown in FIG. 2, the pressure sensor 60 lowers the resistance of the sensor when the pressure of the refrigerant decreases, so that the buzzer described below can be operated at a predetermined pressure. That is, Figure 3 is a circuit diagram showing the main part of the controller connected to the refrigerant leakage detection apparatus according to the present invention. As shown, the controller 70 is provided with a pressure sensor 60 and an indoor temperature sensor 62 and an outdoor temperature sensor 62 installed on the piston, and based on these sensor data, the oscillator 71 is buzzer ( 72) to generate a sound.

제4도는 본 고안에 따른 냉매누설 감지장치의 냉매누설을 감지하는 흐름을 나타낸 흐름도이다. 도시된 바와 같이, 냉각장치의 실내, 실외온도(Rth, Oth)를 읽어(101), 기 설정된 온도(냉방시 또는 난방시의 실내·외온도)의 조건이 되었는지를 판단한다(102).4 is a flowchart illustrating a flow of detecting a refrigerant leakage of the refrigerant leakage detecting apparatus according to the present invention. As illustrated, the indoor and outdoor temperatures (Rth, Oth) of the cooling apparatus are read (101), and it is determined whether the condition of the preset temperature (indoor or outdoor temperature during cooling or heating) has been reached (102).

기 설정된 실내,실외온도가 되었다면, 설정된 소정의 압력수치(P)를 읽고(103), 현재의 냉매량과 비교할 수 있도록 측정된 압력수치(M)을 읽는다(104).If the preset indoor and outdoor temperature is reached, the predetermined pressure value P is read (103), and the measured pressure value (M) is read (104) to be compared with the current amount of refrigerant.

측정된 압력수치(M)와 설정된 압력수치(P)를 비교하여(105), 같다면 타이머를 리세트하고(106)프로그램은 반복 수행한다. 측정된 압력수치(M)와 기 설정된 압력수치(P)가 같지 않다면(105), 측정된 압력수치(M)와 설정된 압력수치(P)를 비교하여 측정된 압력수치(M)가 크다면 타이머를 리세트하고(108)프로그램은 반복 수행하고, 측정된 압력수치(M)와 기 설정된 압력수치(P)의 비교에서(107)측정된 압력수치(M)가 크지 않다면(109)타이머를 동작시키는 것과 동시에 시간 카운터를 한다(111).The measured pressure value M is compared with the set pressure value P (105), and if it is equal, the timer is reset (106) and the program repeats. If the measured pressure value (M) is not equal to the preset pressure value (P) (105), the measured pressure value (M) is compared with the set pressure value (P), and if the measured pressure value (M) is large, the timer (108) and the program is repeatedly executed, and in comparison of the measured pressure value (M) with the preset pressure value (P) (107), if the measured pressure value (M) is not large (109), the timer is operated. At the same time, a time counter is performed (111).

설정된 소정의 시간(T1)이 되었는지를 판단하고(112)설정된 임의시간(T1)이 되지 않았다면 프로그램은 계속 수행하며, 설정된 임의의 시간(T1)이 되었다면 부져를 구동시킨다(113). 부져는 부져해제수신이 있을 때까지 구동하며(114), 해제수신이 있으면 부져로 가는 부호를 차단한다(115).It is determined whether the predetermined time T1 has been set (112). If the set random time T1 has not been reached, the program continues to run, and if the set time T1 is reached, the buzzer is driven (113). The buzzer is driven until there is a buzzer release reception (114), and if there is a release reception block the code to the buzzer (115).

이러한 본 고안의 냉매누설 감지장치는 냉매를 주입할 때 튜브상에 인쇄된 눈금을 확인하면서 냉매를 주입할 수 있으며, 운행중에도 상기 인쇄된 눈금을 확인하여 냉매의 누설여부를 판단할 수 있다. 그리고 실내, 실외온도에 따라 압력차를 감지하여 누설여부를 정확히 판단할 후 사용자에게 알려준다. 그러므로 본 고안의 냉매누설 감지장치는 냉매가 부족할 때, 설정온도까지 최대로 올리기 위해 최대기동으로 인한 압축기의 무리한 운전 및 불 필요한 전력의 소비를 방지할 수 있고, 항상 최적의 상태에서 운행할 수 있도록 하였다.The refrigerant leakage detecting apparatus of the present invention can inject refrigerant while checking the scale printed on the tube when the refrigerant is injected, and can check whether the refrigerant is leaked by checking the printed scale while driving. And it detects the pressure difference according to the indoor and outdoor temperature to accurately determine whether there is a leak and informs the user. Therefore, the refrigerant leakage detection device of the present invention can prevent excessive operation of the compressor and unnecessary power consumption due to the maximum start to raise the temperature up to the set temperature when the refrigerant is insufficient, so that it can always operate in the optimal state It was.
