Description

건설차량용 공조장치HVAC equipment for construction vehicles
기재된 내용은 건설차량의 캐빈 내부에 설치되는 공조장치에 관한 것이다.The description relates to an air conditioner installed inside a cabin of a construction vehicle.
건설차량에 사용되는 공조장치로써 에어컨은 캐빈 내부의 공기를 환기시키거나 캐빈 내부의 온도 및 습도를 조절하고 정화시키는 역할을 한다.As an air conditioner used in construction vehicles, air conditioners serve to ventilate the air inside the cabin or to control and purify the temperature and humidity inside the cabin.
건설차량에 사용되는 에어컨은 캐빈의 내부에 설치되며, 캐빈 내부의 공간적인 제약으로 인해 운전자 시트 아래쪽 또는 시트 뒤쪽에 설치된다.Air conditioners used in construction vehicles are installed inside the cabin, and are installed under the driver's seat or behind the seat due to space constraints inside the cabin.
한편, 에어컨의 내부에는 에어컨으로 유입되는 공기의 정화를 위한 공기필터가 설치되며, 이러한 공기필터는 오염상태에 따라 에어컨의 성능에 영향을 주기 때문에 주기적인 점검과 함께 오염의 정도에 따라 교환된다.On the other hand, the air filter for the purification of the air flowing into the air conditioner is installed in the interior of the air conditioner, since the air filter affects the performance of the air conditioner according to the pollution state is replaced according to the degree of pollution with periodic check.
그러나 종래에는 공기필터를 점검 또는 교체 시 공구를 이용하여 에어컨 커버의 체결볼트를 제거 후 에어컨 커버를 분리시키고, 에어컨 커버 안쪽에 위치한 공기필터 커버의 체결볼트 또한 제거하여 공기필터 커버를 분리시켜야만 공기필터를 꺼내어 점검하거나 새로운 공기필터로 교체할 수 있기 때문에 공기필터의 점검 또는 교체 시 반드시 공구가 필요하게 되며, 공기필터를 점검 또는 교체에 따른 작업과정이 복잡하고, 작업시간이 오래 걸리게 되는 문제점이 있었다.However, conventionally, when checking or replacing the air filter, the air filter cover must be removed after removing the fastening bolt of the air conditioner cover, and the air filter cover must also be removed by removing the fastening bolt of the air filter cover located inside the air conditioner cover.

따라서 에어컨(200)의 외기순환모드에 따라 셔터(330)가 내부공기 흡입구(311)를 폐쇄하더라도 캐빈(100) 내부의 공기는 보조 내부공기 흡입구(313)를 통해 일정 비율이 케이싱(310)의 내부로 유입될 수 있다.Therefore, even if the shutter 330 closes the internal air inlet 311 according to the air circulation mode of the air conditioner 200, the air inside the cabin 100 has a predetermined ratio through the auxiliary internal air inlet 313 of the casing 310. Can be introduced inside.
온도감지부(340)는 바람직하게 보조 내부공기 흡입구(313)를 통해 유입되는 캐빈(100) 내부의 공기의 흐름방향을 고려하여 공기의 흐름방향과 대응되는 케이싱(310) 내부 어느 한쪽에 설치됨에 따라 보조 내부공기 흡입구(313)를 통해 유입된 공기가 다른 공기와 섞이기 전에 온도측정이 이루어질 수 있어 에어컨(200)의 내기순환모드 또는 외기순환모드와 관계없이 순수하게 캐빈(100) 내부 공기의 온도를 정확하게 측정할 수 있다.The temperature sensing unit 340 is preferably installed on either side of the casing 310 corresponding to the flow direction of the air in consideration of the flow direction of the air inside the cabin 100 introduced through the auxiliary internal air inlet 313 Accordingly, the temperature measurement can be made before the air introduced through the auxiliary internal air inlet 313 is mixed with other air, so that the air inside the cabin 100 is purely regardless of the air circulation mode or the air circulation mode of the air conditioner 200. The temperature can be measured accurately.
이와 같이 구성되는 기재된 내용의 실시 예에 따라 캐빈 내부공기 또는 캐빈 외부공기가 필터모듈로 유입되는 과정과, 필터모듈에 설치된 공기필터가 점검 또는 교체되는 과정을 살펴보면 다음과 같다.According to an embodiment of the described contents configured as described above, the process of introducing the cabin interior air or the cabin exterior air into the filter module, and the process of checking or replacing the air filter installed in the filter module are as follows.
우선, 에어컨(200)의 외기순환모드 전환에 따른 신호를 받아 엑추에이터(332)가 작동되면 도 3 에서와 같이 셔터(330)가 케이싱(310)의 내부공기 흡입구(311)를 폐쇄하게 되며, 상대적으로 케이싱(310)의 외부공기 흡입구(312)는 개방된 상태가 됨에 따라 캐빈(100) 외부의 공기는 측벽(110)의 바깥면에 설치되는 외부커버(120)의 하단을 통해 측벽(110)과 외부커버(120) 사이로 유입된 후 측벽(110)의 외부공기 유입공(111)과 케이싱(310)의 외부공기 흡입구(312)를 통해 케이싱(310) 내부로 이동된다.First, when the actuator 332 is operated by receiving a signal according to the change of the air circulation mode of the air conditioner 200, the shutter 330 closes the internal air inlet 311 of the casing 310 as shown in FIG. As the outside air inlet 312 of the casing 310 is in an open state, the air outside the cabin 100 passes through the bottom of the outer cover 120 installed on the outer surface of the side wall 110. After being introduced between the outer cover 120 and the outside air inlet 111 of the side wall 110 and the outside air inlet 312 of the casing 310 is moved into the casing 310.
이후, 케이싱(310)의 내부로 이동된 공기는 아래쪽으로 이동하게 되면서 케이싱(310) 내부에 설치된 공기필터(320)를 통과하여 정화된 상태에서 배출구(360)와 덕트(400)를 거쳐 에어컨(200)의 내부로 이동하게 된다.Subsequently, the air moved into the casing 310 moves downward while passing through the air filter 320 installed inside the casing 310 to be purified, and then through the outlet 360 and the duct 400. 200).
그리고 에어컨(200)이 내기순환모드로 전환되면 그 신호를 받은 엑추에이터가 반대로 작동되면서 도 4 에서와 같이 셔터(330)는 외부공기 흡입구(312)를 폐쇄하게 되며, 상대적으로 케이싱(310)의 내부공기 흡입구(311)는 개방됨에 따라 캐빈(100) 내부의 공기가 내부공기 흡입구(311)를 통해 케이싱(310) 내부로 유입된 후 아래쪽 공기필터(320)를 통과하여 정화된 상태에서 배출구(360)와 덕트(400)를 거쳐 에어컨(200) 내부로 이동하게 된다.When the air conditioner 200 is switched to the bet circulation mode, the actuator that receives the signal is operated in reverse, and as shown in FIG. 4, the shutter 330 closes the external air intake port 312, and relatively the inside of the casing 310. As the air inlet 311 is opened, the air inside the cabin 100 is introduced into the casing 310 through the internal air inlet 311, and then passed through the lower air filter 320 to be purged. ) And the inside of the air conditioner 200 through the duct 400.
아울러, 케이싱(310)의 상부 일측에는 셔터(330)의 작동상태와 관계없이 상시 개방되어 있는 보조 내부공기 흡입구(313)가 형성됨에 따라 에어컨(200)의 내기순환모드 또는 외기순환모드에 관계없이 캐빈(100) 내부의 공기가 보조 내부공기 흡입구(313)를 통해 상시 유입되며, 보조 내부공기 흡입구(313)로 유입된 공기는 보조 내부공기 흡입구(313)와 인접 설치된 온도감지부(340)가 측정한 후 에어컨(200)으로 캐빈 실내 온도에 대한 정보를 전달하게 되므로 에어컨(200)은 캐빈(100) 실내 온도를 정확히 판단하여 적정한 온도조절을 통해 캐빈(100) 내부를 쾌적하게 유지시킬 수 있는 것이다.In addition, the upper one side of the casing 310 is formed in the auxiliary internal air inlet 313 which is always open regardless of the operating state of the shutter 330, regardless of the air circulation mode or the air circulation mode of the air conditioner 200 The air inside the cabin 100 is always introduced through the auxiliary internal air intake 313, and the air introduced into the auxiliary internal air intake 313 is provided with a temperature sensing unit 340 adjacent to the auxiliary internal air intake 313. Since the information about the cabin room temperature is transmitted to the air conditioner 200 after the measurement, the air conditioner 200 accurately determines the cabin temperature of the cabin 100 and can comfortably maintain the cabin 100 through proper temperature control. will be.

따라서 공기필터(320)를 점검 또는 교체하는 경우 운전자는 캐빈(100)의 도어(130)를 개방시킨 상태에서 케이싱(310)의 출입구(314)에 끼워져 있는 공기필터(320)의 손잡이부(322)를 잡아당기게 되면 케이싱(310) 내부에 위치한 가이드(350)로부터 공기필터(320)가 분리되면서 공기필터(320)가 케이싱(310)의 출입구(314)를 통해 인출될 수 있다.Therefore, when inspecting or replacing the air filter 320, the driver handles 322 of the air filter 320 which is fitted to the doorway 314 of the casing 310 with the door 130 of the cabin 100 open. ), The air filter 320 is separated from the guide 350 located in the casing 310, and the air filter 320 may be drawn out through the entrance 314 of the casing 310.
운전자는 케이싱(310)의 출입구(314)를 통해 인출된 공기필터(320)의 오염 상태를 확인한 후 오염이 심하지 않은 경우 간단한 청소 후 케이싱(310)의 출입구(314)를 통해 가이드(350)에 다시 설치할 수 있으며, 공기필터(320)의 오염이 심한 경우 기존 공기필터(320)는 폐기한 후 새로운 공기필터를 준비하여 케이싱(310)의 출입구(314)를 통해 가이드(350)에 슬라이딩시켜 다시 설치하면 된다.The driver checks the contamination state of the air filter 320 drawn out through the doorway 314 of the casing 310, and if the contamination is not severe, the driver may easily clean the guide 350 through the doorway 314 of the casing 310. If the contamination of the air filter 320 is severe, the existing air filter 320 is discarded, and then prepares a new air filter and slides the guide 350 through the entrance 314 of the casing 310 again. Install it.
