Description

차량용 에어컨의 컴프레서 운용방법{COMPRESSOR OPERATION SYSTEM FOR AIRCONDITIONER OF VEHICLE} Compressor operation method of vehicle air conditioner {COMPRESSOR OPERATION SYSTEM FOR AIRCONDITIONER OF VEHICLE}

본 발명은 차량용 에어컨의 컴프레서 운용방법에 대한 것으로, 에어컨 조작 스위치를 복수의 단계로 나누고, 그 각각의 단계에서 컴프레서의 동작점을 사이하게 하여 에어컨 가동시 토출온도가 다르도록 하고자 하는데 특징이 있는 것이다.The present invention relates to a compressor operating method of an air conditioner for a vehicle, characterized in that the air conditioner operation switch is divided into a plurality of stages, and the discharge temperature is different during operation of the air conditioner by interposing the operating points of the compressor in the respective stages. .

일반적으로 차량용 에어컨의 컴프레서는 정해진 동작 온도점에 의해 ON/OFF를 반복하는 형태로 작동한다. In general, the compressor of a vehicle air conditioner operates by repeating ON / OFF by a predetermined operating temperature point.

즉, 에어컨의 냉방성능을 고려하여 증발기의 일측에 온도감지센서를 부착하고 그 증발기의 동결직전 온도점을 선정하여 컴프레서의 동작 온도점을 0℃에서 OFF되고, 4℃에서 ON되도록 하고 있다. That is, the temperature sensor is attached to one side of the evaporator in consideration of the cooling performance of the air conditioner, and the temperature point just before freezing of the evaporator is selected so that the operating temperature point of the compressor is turned off at 0 ° C and turned on at 4 ° C.

따라서 도 1에서 보는 바와 같이 블로워 스위치를 ON시켜 블로워 모터가 작동하게 되었을 때, 에어컨 스위치를 켜면 온도감지센서가 주변 온도를 감지하여 0℃이하이면 컴프레서와 콘덴서의 팬모터을 정지시키고, 4℃이상이면 컴프레서와 콘덴서의 팬모터를 작동시켜 에어컨 가동이 원할하도록 한다. Therefore, when the blower motor is operated by turning on the blower switch as shown in FIG. 1, when the air conditioner switch is turned on, the temperature sensor senses the ambient temperature and stops the fan motor of the compressor and the condenser when it is 0 ° C or lower, and when the blower motor is turned on. Operate the fan motors of the compressor and condenser to make sure the air conditioner is running.

그러나 이러한 컴프레서의 작동은 동작 온도점의 조작을 통한 토출온도 변경이 어렵고, 무엇보다도 차량내외기의 온도 변화에 따른지 않고, 증발기의 동결온도점을 기준으로하기 때문에 토출온도 조절의 변화폭이 작다.However, the operation of the compressor is difficult to change the discharge temperature through the operation of the operating temperature point, and above all, the change range of the discharge temperature control is small because it is based on the freezing temperature point of the evaporator, not depending on the temperature change of the inside and outside of the vehicle.

따라서 사용자가 에어컨을 켜면 춥고, 끄면 더운 것과 같은 현상이 반복되기 때문에 사용이 불편하며 에어컨의 구동이 비능률적이다.Therefore, when the user turns on the air conditioner, it is cold, and when it is turned off, the phenomenon is repeated, which is inconvenient to use and the operation of the air conditioner is inefficient.

따라서 본 발명은 상기와 같은 종래의 문제점을 감안하여 이를 해결하고자 안출한 것으로 발명의 주된 목적은 에어컨의 조작 스위치를 복수의 단계로 구비하고, 그 각각의 스위치조작에 따라 여러 단계로 작동되도록 구성하여 외기 온도에 따른 사용자의 온도 선택폭을 넓히고자 하는데 있고, 또 다른 한편으로는 컴프레서의 운용을 외기 온도에 따라 효율적을 작동시킬 수 있도록 하는데 목적이 있다. Therefore, the present invention has been made to solve the above-mentioned problems in view of the above-mentioned problems. The main object of the present invention is to provide an operation switch of an air conditioner in a plurality of stages, and to operate in various stages according to each switch operation thereof. The purpose of the present invention is to broaden the user's temperature selection range according to the outside temperature, and on the other hand, to operate the compressor efficiently according to the outside temperature.

상기 목적을 달성하기 위한 본 발명의 특징적인 수단은 증발기의 온도감지센서와, 블로워 모터용 스위치와, 제1단과 제2단으로 복수의 에어컨 스위치를 구비하여, 상기 블로워 스위치와 제1단 에어컨 스위치를 켰을 경우, 증발기의 온도감지센서의 감지 값이 0℃보다 작을 때 컴프레서의 작동과 컨덴서의 팬모터의 작동이 정지하고, 증발기의 온도감지센서의 감지 값이 4℃보다 클 때 컴프레서 및 컨덴서의 팬모터가 작동하도록 하며, 상기 블로워 스위치와 제2단 에어컨 스위치를 켰을 경우, 증발기의 온도감지센서의 감지 값이 4℃보다 작을 때 컴프레서의 작동과 컨덴서의 팬모터의 작동이 정지하고, 증발기의 온도감지센서의 감지 값이 8℃보다 클 때 컴프레서 및 컨덴서의 팬모터가 작동하도록 하는 것이다. Characteristic means of the present invention for achieving the above object is provided with a temperature sensing sensor of the evaporator, a blower motor switch, and a plurality of air conditioner switches in the first stage and the second stage, the blower switch and the first stage air conditioner switch When is turned on, the compressor operation and the fan motor of the condenser are stopped when the detected value of the evaporator temperature sensor is less than 0 ℃, and when the detected value of the evaporator temperature sensor is greater than 4 ℃, the compressor and condenser When the fan motor and the blower switch and the second stage air conditioner switch are turned on, the operation of the compressor and the fan motor of the condenser are stopped when the detected value of the temperature sensor of the evaporator is less than 4 ° C. When the sensed value of the temperature sensor is greater than 8 ℃, the fan motor of the compressor and condenser is operated.

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

도 2는 본 발명의 컴프레서 운용방법에 대한 플로우챠트이다.2 is a flowchart illustrating a compressor operating method of the present invention.

본 발명을 적용함에 있어서, 증발기의 온도감지센서와, 블로워 모터용 스위치와, 에어컨 스위치를 구비하는 것을 기본구성으로 하되, 상기한 에어컨 스위치는 제1단과 제2단으로 복수의 에어컨 스위치를 구비한다. In applying the present invention, the temperature sensor, the blower motor switch, and the air conditioner switch of the evaporator is a basic configuration, wherein the air conditioner switch is provided with a plurality of air conditioner switches in the first stage and the second stage. .

이때, 제1단의 에어컨 스위치는 증발기 온도감지센서의 감지 값이 0℃과 4℃일 때 컴프레서를 운용하고, 제2단의 에어컨 스위치는 증발기 온도감지센서의 감지 값이 4℃과 8℃일 때 컴프레서를 운용한다.At this time, the air conditioner switch of the first stage operates the compressor when the detected values of the evaporator temperature sensor are 0 ° C. and 4 ° C., and the air conditioner switch of the second stage has the detected values of the evaporator temperature sensor 4 ° C. and 8 ° C. When the compressor is running.

따라서 운전자가 상기 블로워 스위치와 제1단 에어컨 스위치를 켰을 경우에는 증발기의 온도감지센서의 감지 값이 0℃보다 작을 때 컴프레서의 작동과 컨덴서의 팬모터의 작동이 정지하고, 증발기의 온도감지센서의 감지 값이 4℃보다 클 때 컴프레서 및 컨덴서의 팬모터가 작동하여 에어컨 시스템을 구동한다.Therefore, when the driver turns on the blower switch and the first stage air conditioner switch, when the detected value of the temperature sensor of the evaporator is less than 0 ° C., the operation of the compressor and the fan motor of the condenser are stopped, and the temperature sensor of the evaporator is stopped. When the sensed value is greater than 4 ° C, the fan motors of the compressor and condenser are activated to drive the air conditioning system.

또한, 상기 블로워 스위치와 제2단 에어컨 스위치를 켰을 경우, 증발기의 온도감지센서의 감지 값이 4℃보다 작을 때 컴프레서의 작동과 컨덴서의 팬모터의 작동이 정지하고, 증발기의 온도감지센서의 감지 값이 8℃보다 클 때 컴프레서 및 컨덴서의 팬모터가 작동하여 에어컨 시스템을 구동하는 것이다. In addition, when the blower switch and the second stage air conditioner switch are turned on, when the detected value of the temperature sensor of the evaporator is less than 4 ° C., the operation of the compressor and the fan motor of the condenser are stopped, and the temperature sensor of the evaporator is detected. When the value is higher than 8 ℃, the fan motor of the compressor and condenser is activated to drive the air conditioning system.

이와 같은 본 발명에 따르면 에어컨 스위치를 제1단으로 선택하여 에어컨을 구동시켰을 때, 증발기의 온도감지센서 값이 0℃ ∼ 4℃의 범위에서 작동하므로 컴프레서 및 컨덴서 팬모터가 정상적을 작동할 때, 비교적 차가운 에어컨 바람이 제공되는 바, 그 상태가 적당하면 그대로 사용하고, 비교적 온도가 낮다고 생각되면 사용자는 제2단의 에어컨 스위치를 켜서 에어컨을 구동시킨다.According to the present invention, when the air conditioner switch is selected as the first stage to drive the air conditioner, since the temperature sensor value of the evaporator operates in the range of 0 ° C to 4 ° C, when the compressor and the condenser fan motor operate normally, A relatively cool air conditioner wind is provided. If the condition is appropriate, the air conditioner is used. If the temperature is low, the user turns on the air conditioner switch of the second stage to drive the air conditioner.

제2단의 스위치를 켜서 에어컨을 구동시키면 증발기의 온도감지센서 값이 4℃ ∼ 8℃의 범위에서 작동하므로 컴프레서 및 컨덴서 팬모터가 정상적으로 작동할 때, 제1단으로 구동시켰을 때 보다 약 0℃ ∼ 8℃ 이상 높여진 상태의 공기가 제공되므로 쾌적한 상태가 될 수 있는 것이다. When the air conditioner is operated by switching on the second stage, the temperature sensor value of the evaporator operates in the range of 4 ° C to 8 ° C. When the compressor and the condenser fan motor are operated normally, it is about 0 ° C than when driven to the first stage. It is possible to be in a comfortable state because the air is provided in a state of being raised above 8 ° C.

위에서 상세히 설명한 바와 같은 본 발명은 에어컨 스위치를 복수로 구비하고, 그 각각의 선택에 따라 증발기의 온도감지센서 측정 값이 각각 다른 상태에서 컴프레서의 구동시점을 제공하도록 하였기 때문에 외기 온도에 따라 사용자의 온도 선택폭이 넓어지는 장점이 있으며, 또 다른 한편으로는 컴프레서의 운용을 외기 온도에 따라 여러 단계에서 효율적으로 작동시킬 수 있는 장점이 있다. The present invention as described in detail above is provided with a plurality of air conditioner switch, according to the selection of the temperature sensor of the evaporator to provide the starting point of the compressor in a different state, so that the user's temperature according to the outside temperature The choice is wider, and on the other hand, the compressor can be operated efficiently at various stages depending on the outside temperature.
