Description

오버헤드형 에어컨의 증발기유닛 {Evaporation unite of overhead typr aircondition}Evaporation unit of overhead air conditioner

본 발명은 버스 등의 대형차량에 지붕 탑재형으로 설치되는 오버헤드형 에어컨에 있어서, 이 에어컨의 증발기유닛에 경사진 상태로 설치되는 코어의 배열을 복수열 다층으로 형성하고 상기 증발기유닛의 모서리부분에 상기 코어가 배열되도록하여 상기 증발기유닛의 코어에 외기와의 접촉부위를 넓게 형성하므로서 상기 증발기의 열교환효율을 크게 향상시킬 수 있도록 한 오버헤드형 에어컨의 증발기유닛에 관한 것이다.The present invention provides an overhead air conditioner installed in a roof-mounted type in a large vehicle such as a bus, wherein an array of cores installed in an inclined state in an evaporator unit of the air conditioner is formed in a plurality of rows in a multi-layered multi-layered corner portion The present invention relates to an evaporator unit of an overhead air conditioner, in which the core is arranged in such a manner that a wide contact portion with outside air is formed in the core of the evaporator unit, thereby greatly improving the heat exchange efficiency of the evaporator.

일반적으로 다인승용 버스등에는 차량 내부의 냉방을 위하여 냉방장치를 구비하고 있으며, 상기 냉방을 위해서는 차량의 지붕에 응축기유닛과 증발기유닛이 구비되는 지붕탑재 방식의 오버헤드형 에어컨을 설치하고 있었다.In general, a multi-seat bus or the like is provided with a cooling device for cooling the inside of the vehicle, and for the cooling, a roof-mounted overhead air conditioner having a condenser unit and an evaporator unit is installed on the roof of the vehicle.

또, 상기와 같이 차량에 설치되는 에어컨은 외부로 열을 방출하는 응축기와, 차량내에 설치된 덕트로 저온의 공기를 공급하는 증발기, 냉매를 압축하여 공급하는 압축기등으로 구성되어 있고 압축기가 구동되면 응축기유닛내의 휀(fan)이 작동하면서 응축열을 방출하게 되며 팽창밸브를 통한 냉매는 증발기 유닛내로 흡인된 공기의 열을 흡수하면서 공기를 저온화시키고 이 저온화된 공기를 블로어를 이용하여 차량의 실내로 공급하도록 구성되어 있었으며 상기 증발기유닛은 그 높이의 제한과 열교환된 냉기를 원활하게 차량의 실내로 공급하기 위하여 대체로 경사진 상태로 설치되어 있었다.In addition, the air conditioner installed in the vehicle is composed of a condenser for dissipating heat to the outside, an evaporator for supplying low temperature air to a duct installed in the vehicle, a compressor for compressing and supplying a refrigerant, and the condenser when the compressor is driven. The fan in the unit operates to release the heat of condensation, and the refrigerant through the expansion valve absorbs the heat of the air drawn into the evaporator unit, thereby lowering the air and using the blower to blow the air into the interior of the vehicle. It was configured to supply and the evaporator unit was installed in a generally inclined state in order to supply the limit of the height and the heat exchanged cold air to the interior of the vehicle smoothly.

한편, 상기와 같이 작동되는 에어컨 시스템을 구비한 종래의 것은 도 1에서와 같이 상기 증발기유닛(1)을 경사진 상태로 설치한 상태에서 여러개의 코어(401)를 일렬로 설치하고 이 코어(401)들의 사이에는 열교환을 위한 방열핀(6)을 설치하도록 구성되어 있었으며, 상기 코어는 2개를 1조로하여 냉매가 유입되는 입구측과 냉매가 유출되는 출구측으로 구성하도록 되어 있고 이들 코어에는 블로어로부터 발생되는 공기가 수평상태로 흘러 접촉하도록 되어 있었다.On the other hand, the conventional air conditioner having the air conditioner system operated as described above is installed in a state in which the evaporator unit 1 in an inclined state as shown in FIG. The heat dissipation fins 6 for heat exchange were installed between the cores. The cores consist of two sets of inlet and refrigerant outlets. The air to be flowed in a horizontal state was to be contacted.

그러나, 상기와 같은 종래의 것은 상기 증발기유닛이 경사지게 설치된 상태에서 상기 코어들이 일렬로 설치되어 있기 때문에 블로어로부터 발생된 공기가 상기 코어의 일측에서만 접촉하게 되었으며, 이에 따라 상기 코어와 공기의 접촉률이 매우 적게 되고 또, 상기 증발기유닛의 상하부 모서리부분에서는 상기 공기가 그대로 지나치게 되므로서 증발기유닛에서의 증발효율이 부피에 비하여 크게 저하되고 있었고, 상기 증발효율의 저하에 따라 에어컨의 성능이 저하되는 등의 문제점이 있었다.However, since the cores are arranged in a line in the state in which the evaporator unit is installed in an inclined state, the air generated from the blower contacts only one side of the core, and thus the contact ratio between the core and the air is very high. In addition, in the upper and lower corners of the evaporator unit, the air is too much as it is, the evaporation efficiency in the evaporator unit is greatly reduced compared to the volume, the problem such as the performance of the air conditioner decreases with the decrease in the evaporation efficiency There was this.

본 발명은 상기와 같은 종래의 제반 문제점을 감안하여 안출한 것으로, 본 발명은 버스 등의 대형차량에 지붕 탑재형으로 설치되는 오버헤드형 에어컨에 있어서, 이 에어컨의 증발기유닛에 경사진 상태로 설치되는 코어의 배열을 복수열 다층으로 형성하고 상기 증발기유닛의 모서리부분에 상기 코어가 배열되도록하여 상기 증발기유닛의 코어에 외기와의 접촉부위를 넓게 형성하므로서 상기 증발기의 열교환효율을 크게 향상시킬 수 있도록 한 오버헤드형 에어컨의 증발기유닛을 제공하려는 것인바, 이를 이하에서 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-mentioned conventional problems, and the present invention is an overhead air conditioner installed in a roof-mounted type on a large vehicle such as a bus, and installed in an inclined state on the evaporator unit of the air conditioner. To form a plurality of multi-layered multi-layer array and the core is arranged at the corner of the evaporator unit to form a wide contact area with the outside air in the core of the evaporator unit to greatly improve the heat exchange efficiency of the evaporator It is intended to provide an evaporator unit of an overhead air conditioner, which will be described below in detail with reference to the accompanying drawings.
