Abstract

PURPOSE: A system for operating a compressor in an air conditioner for a vehicle is provided to stabilize operation of an air conditioner and maintain a normal state of the operation. CONSTITUTION: An air conditioner for a vehicle includes a temperature sensor for sensing a temperature of outdoor air so that a compressor is driven or stopped according to the sensed temperature. When the air conditioner stops operating and then operates again due to pause of an engine, the compressor is operated according to the sensed temperature value if the sensed temperature valve of the temperature sensor is lower than a predetermined temperature value. The compressor is operated according to the temperature value measured before the engine stops if the sensed temperature valve of the temperature sensor is higher than the predetermined temperature value.

Description

차량용 에어컨의 컴프레서 운용 시스템{COMPRESSOR OPERATION SYSTEM FOR AIRCONDITIONER OF VEHICLE}Compressor operation system of vehicle air conditioner {COMPRESSOR OPERATION SYSTEM FOR AIRCONDITIONER OF VEHICLE}

본 발명은 차량용 에어컨의 컴프레서 운용 시스템에 대한 것으로, 차량 정차 후, 엔진 및 에어컨이 재가동될 때 외기온도를 감지하는 온도감지센서가 엔진의 잔열을 감지하므로서 비정상적인 에어컨 구동이 발생하지 않도록 예방하고자 하는데 특징이 있는 것이다.The present invention relates to a compressor operating system of a vehicle air conditioner, and after the vehicle is stopped, the temperature sensor for detecting the outside temperature when the engine and the air conditioner is restarted to detect the residual heat of the engine to prevent abnormal air conditioner driving occurs. There is this.

일반적으로 차량용 에어컨은 외기온도를 감지하여 에어컨의 적당한 구동에 이용하는 바, 이와 같이 외기온도를 감지하는 온도감지센서는 대부분 차량의 앞쪽에서 라디에어터의 전면부에 구비된다.In general, the air conditioner for a vehicle senses the outside air temperature and uses it for proper driving of the air conditioner. Thus, a temperature sensor for detecting the outside air temperature is provided at the front of the radiator at the front of the vehicle.

키온(Key ON)하여 엔진이 구동된 상태에서 에어컨 스위치를 ON시키면 에어컨이 함께 구동되는 바, 에어컨은 상기의 온도감지센서의 감지 값에 따라 수시로 컴프레서를 구동/정지 시켜 적절한 온도를 유지하게 된다.When the air conditioner switch is turned on while the engine is driven by the key on, the air conditioner is driven together. The air conditioner keeps the appropriate temperature by driving / stopping the compressor from time to time according to the detected value of the temperature sensor.

그러나 도 1에서 보는 바와 같이 운전중 잠시 휴식 등의 이유로 엔진을 일시정지 시키므로 해서 에어컨 구동이 정지 되었다가 엔진의 구동과 함께 다시 구동되면 그 즉시 에어컨도 구동되는 데, 이때의 에어컨은 차량의 앞부분(엔진가까이)에 구비된 온도감지센서의 감지값을 그대로 적용시켜 에어컨을 구동시키기 때문에 평상적인 주위 온도와 맞지 않게 과잉작동한다.However, as shown in FIG. 1, when the air conditioner is stopped by stopping the engine for a short time while driving, the air conditioner is immediately driven when the air conditioner is stopped again, and the air conditioner is immediately driven. The air conditioner is operated by applying the detected value of the temperature sensor provided near the engine as it is so that it does not operate over the normal ambient temperature.

즉, 엔진은 구동이 일시 정지되더라도 그 주변은 보통의 대기상태와 달리 비교적 높은 온도 상태를 유지하는 바, 엔진 및 에어컨이 재차 구동될 때, 이러한 온도를 온도감지센서가 감지하여 그대로 에어컨 구동에 적용한다는 것은 비정상적인 상태인 것이며, 에어컨의 과잉작동을 유발하는 문제가 있는 것이다.That is, even though the engine is temporarily stopped, its surroundings maintain a relatively high temperature, unlike the normal standby state. When the engine and the air conditioner are driven again, the temperature sensor detects the temperature and applies it to the air conditioner as it is. It is an abnormal condition and there is a problem causing the over-operation of the air conditioner.

따라서 본 발명은 상기와 같은 종래의 문제점을 감안하여 이를 해결 보완하고자 안출한 것으로, 발명의 주된 목적은 엔진이 일시 정지하였다가 재차 구동할 때, 그 주변의 온도 값을 그대로 에어컨 구동에 적용하는 것이 아니라 엔진 정지시간과 측정된 온도 값을 판단하여 임의의 온도 이상으로 비정상적일 때는 엔진정지 이전의 온도값을 기준으로 에어컨이 작동하도록 하는데 있으며, 더 나가서 에어컨의 구동을 안정화 시키고, 과잉구동되는 일이 없이 정상상태를 유지할 수 있도록하는데 목적이 있는 것이다.Accordingly, the present invention has been made to solve and solve the above-mentioned problems in view of the conventional problems. The main object of the present invention is to apply the temperature value of the surroundings to the air conditioner as it is when the engine is temporarily stopped and then driven again. In addition, when the engine stop time and the measured temperature value are judged to be abnormal above an arbitrary temperature, the air conditioner operates based on the temperature value before the engine stop, and further goes out to stabilize the operation of the air conditioner and overdrive The goal is to be able to maintain a steady state without.

상기 목적을 달성하기 위한 본 발명의 특징적인 수단은 외기온도 감지용 온도감지센서를 구비하여, 그 온도감지 값에 따라 컴프레서의 구동 및 정지로 운용되는 차량용 에어컨에 있어서, 엔진의 일시 정지로 인해 에어컨이 구동정지되었다가 재가동 될 때, 상기한 온도감지센서의 감지 값이 특정온도 이하일 때는 그 온도감지 값에 따라 컴프레서를 운용하고, 온도감지센서의 감지 값이 특정온도 이상일 때는 엔진 정지 이전에 측정된 값에 따라 컴프레서를 운용하도록 하는데 있다.A characteristic means of the present invention for achieving the above object is a vehicle air conditioner having a temperature sensor for detecting the outside temperature, operating by driving and stopping the compressor according to the temperature sensing value, the air conditioner due to the pause of the engine When the operation is stopped and restarted, the compressor operates according to the temperature detection value when the above-mentioned temperature sensor is below a certain temperature. It is to operate the compressor according to the value.

이하 본 발명을 첨부 도면에 따라 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 운용에 대한 플로우챠트이다.2 is a flowchart of the operation of the present invention.

본 발명은 외기온도 감지용 온도감지센서를 구비하여, 그 온도감지 값에 따라 컴프레서의 구동 및 정지로 운용되는 차량용 에어컨에 있어서, 엔진의 일시 정지로 인해 에어컨이 구동정지되었다가 재가동 될 때, 상기한 온도감지센서의 감지 값이 특정온도 이하일 때는 그 온도감지 값에 따라 컴프레서를 운용하고, 온도감지센서의 감지 값이 특정온도 이상일 때는 엔진 정지 이전에 측정된 값에 따라 컴프레서를 운용하도록 하는 것이다.The present invention is provided with a temperature sensor for detecting the outside temperature, in the vehicle air conditioner operating by driving and stopping the compressor according to the temperature sensing value, when the air conditioner is stopped and restarted due to the engine pause, the above When the detected value of a temperature sensor is below a certain temperature, the compressor operates according to the temperature detected value. When the detected value of the temperature sensor is above a certain temperature, the compressor operates according to the value measured before the engine stops.

이때, 상기한 특정온도는 약 50℃로 하는 것이 바람직하다.At this time, the specific temperature is preferably set to about 50 ℃.

또한, 상기한 특정온도가 엔진정지 이전의 측정된 값과 대비하여 그 차이가 ±2℃일 때는 에어컨 재가동시 측정된 상기 특정온도에 따라 컴프레서를 운용하도록 한다.In addition, when the specific temperature is compared with the measured value before the engine stop, and the difference is ± 2 ℃ to operate the compressor according to the specific temperature measured when the air conditioner restarts.

이와 같이 운용하면 엔진이 일시 정지하므로 해서 함께 정지되었던 에어컨의 재가동시 온도감지센서가 엔진의 잔열을 감지하는 잘못이 있다 하더라도 그 감지 값이 특정온도 즉, 50℃가 넘기 때문에 그대로 반영하여 운용되지 않는다.In this way, even if the temperature sensor detects the residual heat of the engine when the air conditioner is restarted together because the engine is paused, the detected value is not reflected because it is over a certain temperature, that is, 50 ℃. .

그리고 즉시 엔진이 정지되기 직전의 온도 값을 재가동 기준 온도로 하여 컴프레서가 운용되며, 경우에 따라서 엔진정지 이전의 측정된 값과 대비하여 그 차이가 ±2℃일 때는 곧 그 측정된 온도값을 그대로 적용하여 컴프레서를 운용한다.The compressor is operated immediately using the temperature value just before the engine is stopped as the reference temperature for restarting.In some cases, when the difference is ± 2 ℃ compared to the measured value before the engine stops, the measured temperature value is kept as it is. Apply the compressor.

위에서 상세히 설명한 바와 같은 본 발명은 엔진이 일시 정지하였다가 재차 구동할 때, 그 주변의 온도 값을 그대로 에어컨 구동에 적용하는 것이 아니라 엔진 정지시간과 측정된 온도 값을 판단하여 임의의 온도 이상으로 비정상적일 때는 엔진정지 이전의 온도값을 기준으로 에어컨이 컴프레서가 작동하도록 하였기 때문에 컴프레서 및 에어컨 시스템의 과잉작동이 방지되는 장점이 있으며, 더 나가서 에어컨의 구동이 안정화 되고, 수명이 오래가는 장점이 있다.As described in detail above, the present invention does not apply the ambient temperature value to the air conditioner as it is when the engine is temporarily stopped and then restarts, and the engine stop time and the measured temperature value are judged to be abnormal than an arbitrary temperature. When the air conditioner is to operate the compressor based on the temperature value before the engine stop, there is an advantage that the excessive operation of the compressor and the air conditioning system is prevented, there is an advantage that the operation of the air conditioner is further stabilized, and the life is long.
