Description

온도게이지가 구비된 자동차 에어컨 냉매 매니폴더게이지{Motor air conditioner refrigerant manifold gauge having temperature gauge}Motor air conditioner refrigerant manifold gauge having temperature gauge

본 발명은 자동차용 에어컨의 냉매상태를 점검하는 매니폴더게이지에 관한 것으로, 상세하게는 현재 자동차 에어컨 냉방사이클의 성능점검용 매니폴더게이지에서는 냉매의 압력을 측정하여 압력계의 지침에 의하여 표시하면 그 압력을 기준으로 표화증기표에 의거한 온도를 확인하는 간접적인 냉매온도 측정방법이지만, 본 발명은 매니폴더게이지에 온도센서를 부가하여 냉매의 온도를 직접측정하고 압력과 동시에 온도를 표시해주는 온도게이지가 구비된 매니폴더게이지에 관한 것이다.The present invention relates to a manifold gauge for checking a refrigerant state of a car air conditioner, and more particularly, in the manifold gauge for performance check of a vehicle air conditioner cooling cycle, the pressure of the refrigerant is measured and displayed according to a guide of a pressure gauge. Indirect refrigerant temperature measurement method to check the temperature based on the table steam table based on the present invention, but the present invention is a temperature gauge that directly measures the temperature of the refrigerant by adding a temperature sensor to the manifold gauge and displays the temperature at the same time with the pressure It relates to a provided manifold gauge.

일반적으로 자동차용 에어컨에 사용되는 냉매를 종래에는 R-12를 사용하였으나 오존층을 파괴하는 환경문제로 인하여 근래에는 R-134a를 사용하고 있다.In general, the refrigerant used in the automotive air conditioner in the past used R-12, but due to environmental problems that destroy the ozone layer, R-134a has recently been used.

종래 자동차용 에어컨의 냉매압력을 측정하는 구성으로는 도 1에서 도시한 바와 같이 특허등록 10-0464888호로서 저압측 작동압력 또는 고압측 작동압력을 검측하는 압력검측부와, 상기 압력검측부에 의해 검측된 현재의 작동압력을 나타내는 현재압력표시부와, 그리고 현재의 대기온도에 대한 표준작동압력 및 상기 표준작동 압력을 포함하는 유효압력범위를 나타내는 유효압력표시부를 포함하며, 상기 현재압력표시부에 표시된 현재의 작동압력이 상기 유효압력표시부에 나타난 상기 현재의 대기온도에 대한 유효압력범위 내인 경우 정상으로 판정하고, 상기 유효압력범위를 벗어난 경우 이상으로 판정하는 것으로 정확하게 냉동사이클의 고장여부 및 해당 고장부분을 진단하여 조치할 수 있고, 또한 냉매압력을 측정하는 구성이 제안되어 있다.As a configuration for measuring the refrigerant pressure of a conventional automotive air conditioner, as shown in Fig. 1 as Patent Registration No. 10-0464888, the pressure detecting unit for detecting the low pressure side operating pressure or high pressure side operating pressure, and by the pressure detection unit A current pressure display portion indicating the detected current operating pressure, and an effective pressure display portion indicating an effective pressure range including the standard operating pressure and the standard operating pressure with respect to the current atmospheric temperature, and the current displayed on the current pressure display portion. If the operating pressure is within the effective pressure range for the current atmospheric temperature shown in the effective pressure display section, it is determined to be normal, and if it is out of the effective pressure range, it is determined to be abnormal. A configuration for diagnosing and taking measures and for measuring refrigerant pressure has been proposed.

또 다른 종래기술로는 도 2에서 도시한 바와 같이 실용신안등록 20-0260382호가 있는데, 자동차 냉매가스탱크의 고압측과 저압측에 고압호스와 저압호스를 연결하여 매니폴더게이지로 냉매가스압력을 측정하는 구성으로서 냉매의 압력을 측정하는 장치이다.Another conventional technology is Utility Model Registration No. 20-0260382, as shown in Fig. 2, by connecting a high pressure hose and a low pressure hose to the high pressure side and the low pressure side of the vehicle refrigerant gas tank to measure the refrigerant gas pressure with a manifold gauge. It is an apparatus which measures the pressure of a refrigerant | coolant as a structure to make.

그리고 냉매의 압력을 측정하여 압력계의 지침에 의하여 표시하면 압력계의 압력에 맞춰져서 내부에 기재되어 있는 온도를 확인하는 간접적인 냉매온도 측정방법은 시인성과 신속성이 떨어지며, 이로 인해 작업자가 압력에 맞추어 냉매를 주입한 다음 자동차의 에어컨의 고·저압 냉매 라인을 만져보고 경험치에 의하여 냉매의 적정온도 여부를 판단하는 것으로 불확실한 측정을 하고 있는 실정이다.And if the pressure of the refrigerant is measured and displayed according to the manometer's instructions, the indirect refrigerant temperature measuring method that checks the temperature described inside according to the pressure of the pressure gauge is inferior in visibility and quickness, and thus the operator adjusts the refrigerant to the pressure. After injecting and then touching the high and low pressure refrigerant line of the air conditioner of the car to determine whether the proper temperature of the refrigerant based on the experience is making an uncertain measurement.

그러나 상기의 종래기술은 냉매가스압측정 및 주입게이지가 제안되어 있지만 대기온도에 따른 냉매의 표준압력은 측정할 수 있으나, 냉매온도에 대하여서는 직접측정하는 것이 아니라 냉매압력을 측정한 후 압력계에 기재된 온도를 간접적으로 측정하는 방법과 작업자가 냉매를 주입한 다음 자동차의 냉매 파이프 라인을 만져보고 경험치에 의하여 냉매의 적정온도 여부를 판단하는 것으로 냉매의 실질적인 온도를 측정할 수 없다는 문제점이 있고 작업자가 쉽고 편리하게 에어컨 냉매온도는 측정할 수 없다.However, although the conventional technology of the refrigerant gas pressure measurement and injection gauge is proposed, the standard pressure of the refrigerant according to the atmospheric temperature can be measured, but the temperature described in the pressure gauge after measuring the refrigerant pressure rather than measuring the refrigerant temperature directly. Method of indirect measurement and operator injects the refrigerant and then touches the refrigerant pipeline of the vehicle and judges the proper temperature of the refrigerant based on the experience value, so that the actual temperature of the refrigerant cannot be measured. For example, air conditioner refrigerant temperature cannot be measured.

본 발명은 상기의 문제점을 해결하기 위한 것으로, 매니폴더게이지에 온도센서를 부가하여 냉매의 온도를 직접측정하고 압력과 동시에 온도를 표시해주는 온도게이지가 구비된 매니폴더게이지의 구성을 제공하는데 그 목적이 있다.The present invention is to solve the above problems, by providing a temperature sensor to the manifold gauge to provide a configuration of the manifold gauge with a temperature gauge that directly measures the temperature of the refrigerant and displays the temperature at the same time as the pressure thereof. There is this.

또한 상기의 구성으로 인하여 작업자가 용이하게 에어컨의 냉매온도를 직접측정할 수 있게 하는데 또 다른 목적이 있다.In addition, it is another object to enable the operator to directly measure the refrigerant temperature of the air conditioner due to the above configuration.
