Abstract

The coolant amount abnormality indicating method consists of the coolant amount detection(S1), the coolant amount abnormality detection(S2), and the coolant amount abnormality indication(S3). The method, at the coolant amount detection, detects the coolant amount inside of the air conditioner by using the pressure sensor while it is running and at the coolant amount abnormality detection, detects the abnormality of the coolant excessive amount condition or the insufficient amount condition by comparing the detected coolant amount(P) with the desired value(K1,K2) and at the coolant amount abnormality indication, repeats the coolant detection if the coolant amount is in normal condition. Also, if the coolant amount is in the excessive or the insufficient condition, it alerts driver of the coolant amount abnormality by activating the indicator installed on the dash board.

본 발명은 차량용 에어컨 장치의 탱크내 냉매량 과다/부족 표시방법에 관한 것으로서, 더욱 상세하게 말하자면 자동차 에어컨 장치에 있어서 냉매량 과다 또는 냉매량 부족과 같은 냉매량의 이상(異常)을 표시하여 줌으로써 사용자로 하여금 냉매의 공급을 원활하게 할 수 있도록 하는 차량용 에어컨 장치의 탱크내 냉매량 과다/부족 표시방법에 관한 것이다.The present invention relates to a method for displaying the amount of refrigerant in the tank of the vehicle air conditioner in excess / low, more specifically, in the vehicle air conditioner by displaying an abnormality of the amount of refrigerant such as the amount of refrigerant in excess or the amount of refrigerant in the vehicle air conditioner The present invention relates to a method for indicating an excessive / low amount of refrigerant in a tank of a vehicle air conditioner to facilitate supply.

현대인의 생활중에서 자동차내에서의 생활이 많아지게 됨에 따라 여름철에 자동차내의 환경을 쾌적하게 유지하기 위한 에어컨이 자동차에 거의 필수적으로 장착되고 있다. 상기한 에어컨은 오랜기간동안 사용하지 않게 되면 냉매가 증발되어 버리기 때문에 이와같은 냉매의 증발을 막기 위해서는 에어컨을 전혀 사용하지 않는 겨울철에도 가끔씩은 에어컨을 동작시켜 주어야만 한다.As life in cars increases in modern people's lives, air conditioners are almost essential to automobiles in order to maintain a comfortable environment in the summer. Since the air conditioner is not used for a long time, the refrigerant is evaporated, so in order to prevent the evaporation of such refrigerant, it is necessary to operate the air conditioner occasionally even in winter when the air conditioner is not used at all.

그러나, 종래의 차량에는 에어컨 장치의 냉매량의 과다 및 부족을 표시하여 주는 장치가 없기 때문에 겨울철에 운전자가 냉매가 증발되고 있는데도 이를 모르고 지나친 경우에, 여름철에 에어컨 장치를 가동시키게 되면 냉매량 부족으로 인하여 에어컨 장치의 냉방기능이 급격하게 저하되어 있는 문제점이 있다.However, in the conventional vehicle, since there is no device indicating the amount and amount of refrigerant in the air conditioner, when the driver does not know the refrigerant evaporates in the winter, but excessively, if the air conditioner in the summer to operate the air conditioner due to lack of refrigerant There is a problem that the cooling function of the device is sharply lowered.

이와 같은 문제점은, 냉방기능을 정상적으로 유지하기 위해서 여름철이 될 때마다 냉매를 재충전해주어야 하는 경제적, 시간적인 낭비를 유발시키는 원인이 된다.Such a problem causes economic and time waste to recharge the refrigerant every summer in order to maintain the cooling function normally.

본 발명의 목적은 상기한 바와 같은 종래의 문제점을 해결하기 위한 것으로서, 에어컨 장치의 탱크내의 냉매량을 감지하여 냉매량의 과다 및 부족을 운전자에게 표시하여 줌으로써 운전자가 냉매량을 적정하게 유지시킬 수 있도록 하는 차량용 에어컨 장치의 탱크내 냉매량 과다/부족 표시방법을 제공하는 데 있다.An object of the present invention is to solve the conventional problems as described above, by detecting the amount of refrigerant in the tank of the air conditioner device to display the excess and shortage of the refrigerant amount to the driver to enable the driver to properly maintain the refrigerant amount An object of the present invention is to provide a method for indicating an excessive / low amount of refrigerant in a tank of an air conditioner.

이하, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 본 발명을 용이하게 실시할 수 있을 정도로 상세히 설명하기 위하여, 본 발명의 가장 바람직한 실시예를 첨부된 도면을 참조로 하여 설명하기로 한다.Hereinafter, the most preferred embodiments of the present invention will be described with reference to the accompanying drawings in order to be described in detail to those skilled in the art can easily practice the present invention.

제1도는 본 발명의 실시예에 따른 차량용 에어컨 장치의 탱크내 냉매량 과다/부족 표시방법의 동작 순서도 이다. 제1도에 도시되어 있는 바와 같이, 본 발명의 실시예에 따른 차량용 에어컨 장치의 탱크내 냉매량 과다/부족 표시방법은, 에어컨 장치가 작동되면 압력센서를 이용하여 에어컨 장치의 냉매량을 검출하는 냉매량검출단계(S1)과, 상기 검출된 냉매량이 정상인지 과다/부족인지를 판단하는 냉매량이상(異常)검출단게(S2)와, 상기 냉매량이상검출단계(S2)에서 검출된 냉매량이 정상인 경우 다시 상기 냉매량검출단계(S1)를 수행하고, 상기 검출된 냉매량이 이상(異常)인 경우 냉매량의 이상(異常)을 사용자에게 표시하는 냉매량이상 표시단계(S3)로 구성된 것을 그 기술적 구성상의 특징으로 한다.FIG. 1 is a flowchart illustrating an operation of displaying an excessive / low amount of refrigerant in a tank of a vehicle air conditioner according to an exemplary embodiment of the present invention. As shown in FIG. 1, the method of displaying an excess / low amount of refrigerant in a tank of a vehicle air conditioner according to an embodiment of the present invention detects the amount of refrigerant that detects the amount of refrigerant in the air conditioner using a pressure sensor when the air conditioner is operated. Step (S1), the amount of refrigerant to determine whether the detected amount of refrigerant is normal or excessive / insufficient (S2) and the amount of refrigerant when the amount of refrigerant detected in the phase detection step (S2) is normal again the amount of refrigerant When the detection step (S1) is performed, and the detected amount of the refrigerant is abnormal, the technical configuration is characterized in that the refrigerant amount configured to display the abnormal amount of the refrigerant amount to the user (S3).

상기한 구성에 의한, 본 발명의 실시예에 따른 차량용 에어컨 장치의 탱크내 냉매량 과다/부족 표시방법의 작용을 상세히 설명하면 다음과 같다.The operation of the method for displaying the amount of refrigerant in the tank excess / lack of the vehicle air conditioner according to the embodiment of the present invention by the above configuration in detail as follows.

먼저, 냉매량 검출단계(S1)에서는 에어컨 장치가 작동되는 동안 에어컨 장치의 내부의 냉매량을 압력센서를 이용하여 검출한다.First, in the refrigerant amount detecting step S1, the refrigerant amount inside the air conditioner is detected using a pressure sensor while the air conditioner is operating.

다음에, 냉매량이상(異常) 검출단계(S2)에서는, 상기 냉매량 검출단계(S1)에서 검출된 냉매량(P)을 소정의 값(K1, K2)과 비교하여 냉매량의 과다 및 부족, 즉 냉매량의 이상(異常)을 검출한다. 즉, 상기 검출된 냉매량(P)이 일정값(K1)보다 크면 냉매량 과다상태로, 상기 검출된 냉매량(P)이 일정값(K2) 이하이고 일정값(K2) 이상이면 냉매량 정상상태로, 그리고 상기 검출된 냉매량(P)이 일정값(K2)보다 작으면 냉매량 부족상태로 판단한다. 이때, 상기 냉매량의 이상(異常)을 판단하는 기준인 일정값(K1, K2)은 차량의 종류에 따라 다르게 설정할 수가 있다.Next, in the coolant amount phase detecting step S2, the coolant amount P detected in the coolant amount detecting step S1 is compared with a predetermined value K1, K2, so that the coolant amount is excessive and insufficient, that is, Abnormality is detected. That is, if the detected refrigerant amount P is larger than the predetermined value K1, the refrigerant amount is in an excessive state, and if the detected refrigerant amount P is equal to or less than the predetermined value K2 and equal to or greater than the predetermined value K2, the refrigerant amount is in a normal state, and If the detected refrigerant amount P is smaller than the predetermined value K2, it is determined that the refrigerant amount is insufficient. At this time, the constant values K1 and K2, which are criteria for determining abnormality of the refrigerant amount, may be set differently according to the type of vehicle.

다음에, 냉매량이상 표시단계(S3)에서는, 상기 냉매량이상(異常)검출단계(S2)에서 냉매량이 정상상태로 판단되는 경우에는 상기 냉매량 검출단계(S1)를 다시 수행함으로써 에어컨 장치가 작동되는 동안 계속 냉매량을 검출하고, 냉매량이 과다 또는 부족상태로 판단되는 경우에는 운전석 계기판에 설치된 경고등을 작동시킴으로써 사용자에게 냉매량의 이상(異常)을 표시한다. 따라서, 사용자는 경고등을 통하여 에어컨 장치의 냉매량이 정상인지, 아니면 이상이 있는지를 손쉽게 확인할 수가 있기 때문에 이를 통하여 냉매량이 항상 일정하게 유지될 수 있도록 관리할 수가 있다.Next, in the refrigerant amount phase display step S3, when the refrigerant amount is determined to be in a normal state in the phase amount detection step S2, while the air conditioner is operating by performing the refrigerant amount detection step S1 again. If the amount of coolant is continuously detected and it is determined that the amount of coolant is excessive or insufficient, the warning lamp provided in the driver's seat instrument panel is operated to display an abnormality of coolant amount to the user. Therefore, the user can easily check whether the refrigerant amount of the air conditioner device is normal or abnormal through the warning lamp, so that the refrigerant amount can be managed to be kept constant at all times.

이상에서 살펴본 바와 같이, 본 발명의 실시예에 따른 차량용 에어컨 장치의 탱크내 냉매량 과다/부족 표시방법은 에어컨 장치의 탱크내 냉매량의 이상(異常)을 표시하여 줌으로써 사용자로 하여금 냉매량이 일정하게 유지될 수 있도록 하는 유용한 작용효과를 갖는다.As described above, the method of displaying an excessive / low amount of refrigerant in a tank of a vehicle air conditioner according to an exemplary embodiment of the present invention displays an abnormality of the amount of refrigerant in a tank of the air conditioner so that the user can maintain a constant amount of refrigerant. It has a useful effect to make it possible.
