Description

차량용 공조시스템 {AIR CONDITIONING SYSTEM FOR VEHICLE}TECHNICAL FIELD [0001] The present invention relates to an air conditioning system for a vehicle,

본 발명은 차량용 공조장치의 구조에 관한 것으로, 더욱 상세하게는 특정 운행 환경에서 보다 효율적 공조를 위한 공조시스템의 구성에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an air conditioner for a vehicle, and more particularly, to a configuration of an air conditioner system for efficient air conditioning in a specific operating environment.

자동차에는 실내를 냉, 난방하기 위한 공조시스템이 설치된다. 이러한 공조시스템은, 차량의 실내온도를 항상 쾌적하게 유지시키는 것이 중요한 과제로 되어 있다.The automobile is provided with an air conditioning system for cooling and heating the room. In such an air conditioning system, it is an important task to always keep the indoor temperature of the vehicle pleasantly.

차량용 공조시스템 중 냉각기는 냉매를 압축하는 컴프레서, 컴프레서에서 압축된 냉매를 응축하는 응축기, 응축기에서 응축되어 액화된 냉매를 저온 저압의 상태로 만드는 팽창밸브, 그리고 냉매의 증발 잠열을 이용하여 공기를 냉각하는 증발기 등을 구성요소로서 포함한다. 일반적으로 이러한 냉각 시스템은 공기의 온도를 낮추며 절대 습도를 조절한다.In the automotive air conditioning system, the cooler includes a compressor for compressing the refrigerant, a condenser for condensing the refrigerant compressed in the compressor, an expansion valve for converting the refrigerant condensed in the condenser into a low-temperature and low-pressure state, And the like. Typically, these cooling systems lower the temperature of the air and regulate absolute humidity.

난방은 엔진룸의 열을 식히기 위한 냉각수가 엔진의 열을 빼앗아 고온의 상태가 되었을 때 이것을 열원으로 사용하며 히터코어와 엔진의 냉각수의 순환을 위한 펌프로 구성이 된다. 일반적으로 이러한 난방 시스템은 공기의 온도를 높히며 상대습도를 조절한다.Heating is composed of a heater core and a pump for circulating the cooling water of the engine when the cooling water for cooling the engine room takes the heat of the engine and becomes a high temperature state as a heat source. In general, these heating systems increase the temperature of the air and regulate the relative humidity.

일반적인 기존의 공조시스템의 경우 냉기의 공급은 냉각기에서 온기의 공급은 엔진의 냉각수를 통하여 공급하였으나 운행되는 환경에 따라 구조의 변경이 필요할 수 있다. 특히 엔진의 냉각수가 없는 경우에는 기존의 공조시스템은 구성하기 어렵고 비효율적인 문제가 있었다.In case of conventional air conditioning system, supply of cold air from cooler is supplied through cooling water of engine, but it may be necessary to change structure depending on the environment in which it is operated. Especially, when there is no cooling water of the engine, the conventional air conditioning system is difficult to construct and has a problem of inefficiency.

상기의 배경기술로서 설명된 사항들은 본 발명의 배경에 대한 이해 증진을 위한 것일 뿐, 이 기술분야에서 통상의 지식을 가진자에게 이미 알려진 종래기술에 해당함을 인정하는 것으로 받아들여져서는 안 될 것이다.It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.

도 2를 참고하여 살펴보면, 본 발명은 하나의 냉각라인 상에 팽창밸브(303), 에바코어(109), 컴프레서(301), 컨덴서를 모두 배치함으로써 컴프레서(301)를 통과한 고온고압의 냉매를 열원으로 사용하게 된다. 즉 기존의 차량용 공조시스템 중에서 냉각시스템만을 이용하여 냉방과 난방을 동시에 할 수 있는 효과가 있다. 이는 엔진 냉각수 등의 열원을 확보할 수 없는 경우 유용하게 사용될 수 있다.2, the present invention is characterized in that both the expansion valve 303, the eva core 109, the compressor 301, and the condenser are disposed on one cooling line, and the refrigerant of high temperature and high pressure, which has passed through the compressor 301, It is used as a heat source. That is, it is possible to simultaneously perform cooling and heating by using only the cooling system among the existing automotive air conditioning systems. This can be useful when the heat source such as engine cooling water can not be secured.

또한 본 발명에 따른 차량용 공조시스템은 난방을 위한 별도의 히팅라인 및 워터펌프가 필요없어 구조가 단순화되고, 이너 컨덴서(209) 및 아우터 컨덴서(211)를 배치함으로써 공조시스템이 냉방모드로 작동하는 경우 냉매의 냉각영역이 확장되어 방열효율이 높아짐으로써 공조시스템의 효율이 개선되는 효과가 있다.

제1 3-WAY밸브 내지 제2 3-WAY밸브의 동작상태를 조절하는 제어부(400);를 더 포함하고, 공조시스템이 난방모드로 가동하는 경우, 제어부(400)는 제1삼방밸브와 제2삼방밸브를 제어하여 냉매가 난방순환유로(503)를 순환하도록 제어할 수 있다.And a controller (400) for controlling an operation state of the first 3-way valve to the second 3-way valve. When the air conditioning system is operated in the heating mode, the controller (400) 2 three-way valve so that the refrigerant circulates through the heating circulation flow path 503.

도 2을 참고하여 살펴보면 냉방순환유로(501)는 냉매가 에바코어(109), 컴프레서(301), 제1 3-WAY밸브, 아우터 컨덴서(211), 제2 3-WAY밸브, 이너 컨덴서(209) 및 팽창밸브(303)를 순환하도록 구성되어 있다. 난방순환유로(503)는 냉매가 에바코어(109), 컴프레서(301)를 통과한 후 제1 3-WAY밸브에서 분기되어 아우터 컨덴서(211)를 통과하지 않고 바로 제2 3-WAY밸브로 유입되어 이너 컨덴서(209) 및 팽창밸브(303)를 순환하도록 구성되어 있다.2, the cooling circulation flow path 501 includes a refrigerant flow path including an evaporator 109, a compressor 301, a first 3-way valve, an outer condenser 211, a second 3-way valve, an inner condenser 209 And the expansion valve 303 are circulated. The heating circulation flow path 503 is branched from the first 3-way valve after the refrigerant passes through the evaporator 109 and the compressor 301 and flows into the second 3-way valve without passing through the outer condenser 211 And is configured to circulate the inner condenser 209 and the expansion valve 303.

공조시스템이 냉방모드로 작동하고 있는 경우 공조시스템의 효율을 높이기 위해서는 컨덴서의 방열량을 늘려 컨덴서를 통과하는 냉매의 온도를 빠르게 낮춰주어야 팽창밸브(303)를 통과한 냉매가 에바코어(109)로 유입될 때 냉매의 온도가 낮아져 냉방덕트(101)를 통과하는 공기로부터 많은 양의 열을 흡수할 수 있게 된다. 이때 본 발명에서는 도 5에 도시된 바와 같이 냉매가 냉방순환유로(501)를 순환하도록 하여 공냉식의 이너 컨덴서(209) 뿐만이 아니라 수냉식의 아우터 컨덴서(211)를 통해 냉매의 방열량을 늘려줌으로써 공조시스템의 효율증가를 도모한다.In order to increase the efficiency of the air conditioning system when the air conditioning system is operating in the cooling mode, the temperature of the refrigerant passing through the condenser must be rapidly lowered by increasing the heat radiation amount of the condenser. Therefore, the refrigerant passing through the expansion valve 303 flows into the evaporator core 109 The temperature of the refrigerant can be lowered to absorb a large amount of heat from the air passing through the cooling duct 101. 5, the refrigerant circulates the cooling circulation flow passage 501 to increase the heat radiation amount of the refrigerant through the water-cooled outer condenser 211 as well as the air-cooled inner condenser 209, Thereby increasing the efficiency.

또한 난방모드로 동작하고 있는 경우에는 컨덴서를 통과하는 냉매의 온도가 높아야 난방덕트(201)를 통과하는 공기에 공급할 수 있는 열량이 증가하므로 냉매가 도 6에 도시된 바와 같이 난방순환유로(503)를 순환하도록 하여 수냉식의 아우터 컨덴서(211)를 통과하지 않도록 함으로써 난방시의 효율증가를 함께 도모한다.In addition, when the refrigerant is operating in the heating mode, the amount of heat that can be supplied to the air passing through the heating duct 201 increases because the temperature of the refrigerant passing through the condenser is high, so that the refrigerant is circulated through the heating circulation channel 503, So as not to pass through the water-cooled outer condenser 211, thereby simultaneously increasing the heating efficiency.

냉방덕트(101)의 실내유출구와 실외유출구 사이에 마련되어 공기의 외부 유출량을 조절하는 냉방측 배기조절도어(113); 난방덕트(201)의 실내유출구와 실외유출구 사이에 마련되어 공기의 외부 유출량을 조절하는 난방측 배기조절도어(213);를 포함할 수 있다.A cooling air exhaust control door (113) provided between an indoor air outlet of the cooling duct (101) and the outdoor air outlet to regulate the amount of air to be flown out; And a heating side exhaust control door 213 provided between the indoor air outlet and the outdoor air outlet of the heating duct 201 to regulate the amount of the outside air flowing out.

도 3 내지 도 4를 참고하여 살펴보면, 본 발명은 냉방측 배기조절도어(113) 및 난방측 배기조절도어(213)를 통하여 공조된 공기의 실내공급 또는 실외배기 여부를 조절할 수 있게 된다. 냉방측 배기조절도어(113) 및 난방측 배기조절도어(213)를 조절하여 냉방모듈 또는 난방모듈에 의해 공조 된 공기의 혼합배율을 조절함으로써 정밀한 실내 공조가 가능하게 된다.3 to 4, the present invention can control indoor air supply or outdoor air exhaust through the air conditioner side air conditioner door 113 and the air conditioner side air conditioner door 213. The air conditioner side air conditioner door 113 and the air conditioner side air conditioner door 213 are adjusted to control the mixing ratio of the air supplied by the cooling module or the heating module.

풍량조절도어(111)의 동작을 조절하는 제어부(400);를 더 포함하고, 제어부(400)는 공조시스템이 냉방모드로 가동하는 경우 풍량조절도어(111)를 제어하여 냉방덕트(101)측의 공기의 일부를 난방덕트(201)에 공급할 수 있다.The control unit 400 controls the air volume control door 111 to control the operation of the air conditioning duct 101 when the air conditioning system is operated in the cooling mode, It is possible to supply a part of the air of the heating duct 201 to the heating duct 201.

풍량조절도어(111)의 동작을 조절하는 제어부(400);를 더 포함하고, 제어부(400)는 공조시스템이 난방모드로 가동하는 경우 풍량조절도어(111)를 제어하여 난방덕트(201)측의 공기의 일부를 냉방덕트(101)에 공급할 수 있다.The control unit 400 controls the air volume control door 111 to control the operation of the air conditioner door 111 when the air conditioning system is operated in the heating mode, It is possible to supply a part of the air of the cooling duct 101 to the cooling duct 101.

본 발명의 경우 냉방덕트(101) 및 난방덕트(201)에 공기를 공급하기 위한 블로워는 공통블로워(115) 하나뿐이다. 다만, 공조시스템이 냉방 또는 난방을 수행하는 경우 각 덕트 내에서의 풍량을 달리 조절할 필요가 있는 경우가 발생한다.In the present invention, only one common blower 115 blows air to the cooling duct 101 and the heating duct 201. However, when the air conditioning system performs cooling or heating, it may be necessary to adjust the airflow in each duct differently.

예를 들어 공조시스템이 냉방모드로 작동하는 경우 냉방덕트(101)의 에바코어(109)를 통과하는 공기는 많은 양이 통과하기보다 적은 공기라도 온도를 많이 낮추어 실내로 공급하는 것이 실내공기를 냉방하는데 있어서 유리하다. 또한, 앞서 언급한바와 같이 컨덴서의 방열량을 늘려주어야 에바코어(109)를 통과하는 냉매의 온도를 낮추어 냉방효율을 증가시킬 수 있게된다.For example, in a case where the air conditioning system operates in the cooling mode, air passing through the evaporator core 109 of the cooling duct 101 is supplied to the room while lowering the temperature even if there is a small amount of air passing therethrough. . In addition, as described above, the amount of heat radiation of the condenser must be increased to lower the temperature of the refrigerant passing through the eva core 109, thereby increasing the cooling efficiency.

따라서 본 발명에서는 도 3에 도시된 바와 같이 풍량조절도어(111)를 제어하여 냉방모드 작동시 냉방덕트(101)로 유입되는 공기의 일부가 난방덕트(201)에 공급되도록하여 컨덴서에서의 방열량을 증가시키고 에바코어(109)를 통과하는 공기의 온도를 더 낮추어 차량의 실내 냉방공조의 효율을 높일 수 있게된다.Accordingly, in the present invention, as shown in FIG. 3, a part of the air flowing into the cooling duct 101 is supplied to the heating duct 201 by controlling the air amount control door 111 so that the amount of heat radiation from the condenser The temperature of the air passing through the eva core 109 can be further lowered, and the efficiency of the indoor cooling and air conditioning of the vehicle can be increased.

마찬가지로 공조시스템이 난방모드로 작동하는 경우 난방덕트(201)의 컨덴서를 통과하는 공기는 많은 양이 통과하기보다 적은 공기라도 온도를 많이 높혀 실내로 공급하는 것이 실내공기를 난방하는데 있어서 유리하다. 또한 에바코어(109)에서의 흡열량이 증가되어야 냉매의 온도가 높아져 컨덴서의 온도를 높혀 컨덴서를 통과하는 공기의 온도를 더 상승시킬 수 있게 된다.Similarly, when the air conditioning system operates in the heating mode, air passing through the condenser of the heating duct 201 is advantageous in heating indoor air by supplying a large amount of air to the room even if a small amount of air passes through the condenser. Also, since the temperature of the refrigerant increases to increase the temperature of the condenser, the temperature of the air passing through the condenser can be further increased.

따라서 본 발명에서는 도 4에 도시된 바와 같이 풍량조절도어(111)를 제어하여 난방모드 작동시 난방덕트(201)로 유입되는 공기의 일부가 냉방덕트(101)에 공급되도록 하여 에바코어(109)에서의 흡열량을 증가시키고 컨덴서를 통과하는 공기의 온도를 더 상승시켜 차량의 실내 난방공조의 효율을 높일 수 있게된다.Accordingly, in the present invention, as shown in FIG. 4, the air volume control door 111 is controlled to allow a part of the air flowing into the heating duct 201 to be supplied to the cooling duct 101 during the heating mode operation, The efficiency of the indoor heating and air conditioning of the vehicle can be increased by increasing the amount of heat absorbed in the condenser and further increasing the temperature of the air passing through the condenser.

냉방측 배기조절도어(113) 및 난방측 배기조절도어(213)의 동작상태를 제어하는 제어부(400);를 더 포함하고, 공조시스템이 냉방모드로 가동하는 경우, 제어부(400)는 냉방측 배기조절도어(113)가 냉방측 실내유출구(107)를 폐쇄하도록 제어하고, 난방측 배기조절도어(213)가 난방측 실내유출구(205)를 폐쇄하도록 제어할 수 있다.The control unit 400 further includes a control unit 400 for controlling the operation states of the cooling side exhaust control door 113 and the heating side exhaust control door 213.
