汽车空调系统分类以及特点介绍

一、汽车空调系统分类
1、 Classification of automobile air conditioning system
1.独立式空调:有专门的动力源(如第二台内燃机)驱动整个空调系统的运行。一般用于长途货运、高地板大中巴等车上。独立式空调由于需要两台发动机,燃油消耗高,同时造成较高的成本,并且其维修及维护十分困难,需要十分熟练的发动机维修人员,而且发动机配件不易获得,尤其是进口发动机;另外设计和安装更容易导致系统质量问题的发生,而额外的驱动发动机更增加了发生故障的概率。
1. Independent air conditioning: there is a special power source (such as the second internal combustion engine) to drive the operation of the whole air conditioning system. Generally used for long-distance freight, highland plate bus and other vehicles. The independent air conditioner needs two engines, so the fuel consumption is high and the cost is high at the same time. It is very difficult to repair and maintain. It needs very skilled engine maintenance personnel, and the engine parts are not easy to obtain, especially the imported engine; In addition, the design and installation are more likely to lead to system quality problems, and the additional drive engine increases the probability of failure.
2.非独立式空调:直接利用汽车的行驶动力(发动机)来运转的空调系统。非独立式空调由主发动机带动压缩机运转,并由电磁离合器进行控制。接通电源时,离合器断开,压缩机停机,从而调节冷气的供给,达到控制车厢内温度的目的。其优点是结构简单、便于安装布置、噪音小。由于需要消耗主发动机10%-15%的动力,直接影响汽车的加速性能和爬坡能力。同时其制冷量受汽车行驶速度影响,如果汽车停止运行,其空调系统也停止运行。尽管如此,非独立式空调由于其较低的成本(相对独立式空调),可*的质量,已逐渐成为市场的主导产品。目前,绝大部分轿车、面包车、小巴都使用这种空调。目前非独立式空调。
2. Non independent air conditioning: an air conditioning system that directly uses the driving power (engine) of the car to operate. The compressor is driven by the main engine and controlled by the electromagnetic clutch. When the power is turned on, the clutch is disconnected and the compressor stops, so as to regulate the supply of cold air and control the temperature in the car. The utility model has the advantages of simple structure, convenient installation and arrangement, and low noise. Because it needs to consume 10% - 15% of the power of the main engine, it directly affects the car's acceleration performance and climbing ability. At the same time, its cooling capacity is affected by the speed of the car. If the car stops running, its air conditioning system will also stop running. However, due to its low cost (relative to the independent air conditioner) and reliable quality, the non independent air conditioner has gradually become the leading product in the market. At present, most cars, minibuses and minibuses use this kind of air conditioner. At present, it is not a stand-alone air conditioner.
二、汽车空调系统特点
2、 Characteristics of automobile air conditioning system
(1)空调装置运行时振动较大
(1) The vibration of the air conditioner is large
前面已提到汽车空调装置是移动式车载空调装置,由于道路不平,汽车在行驶中颠簸振动大,所以装置中连接管道应采用挠性制冷剂管道。
As mentioned above, the automobile air conditioning device is a mobile vehicle air conditioning device. Due to the uneven road, the car bumps and vibrates heavily during driving, so the flexible refrigerant pipe should be used in the connecting pipe of the device.
(2)冷凝器紧靠着发动机的散热器,所以它的冷凝温度往往是低高的,所以其运行工况比其它空调装置恶劣。
(2) The condenser is close to the radiator of the engine, so its condensation temperature is often low and high, so its operation condition is worse than other air conditioning devices.
(3)汽车空调系统的压缩机是直接由发动机驱动的,它是通过一个皮带驱动机构来实现的。当压缩机不工作时,压缩机可以与发动机脱开,它是通过一个电子离合器来实现的。空调系统停止工作时,应经常检查皮带的松紧,以确定离合器动作是否正确,有时离合器因轴承的损坏而影响压缩机的轴封,造成压缩机轴封处制冷剂泄漏。所以要检查离合器轴承损坏的早期迹象
(3) The compressor of automobile air conditioning system is directly driven by the engine, which is realized by a belt driving mechanism. When the compressor does not work, the compressor can be separated from the engine through an electronic clutch. When the air conditioning system stops working, the tightness of the belt should be checked frequently to determine whether the clutch action is correct. Sometimes the clutch will affect the shaft seal of the compressor due to the damage of the bearing, resulting in the refrigerant leakage at the shaft seal of the compressor. So check for early signs of clutch bearing damage
