没有空调系统的装载机不能算是一台完整的机器，司机朋友们在无制冷的环境中驾驶装载机的时候必然会有种种不适，这样容易增加操作风险。了解装载机空调系统基础知识，保证装载机空调系统能够稳定制冷，营造一个凉快舒适的驾驶环境，对山东装载机司机朋友来说十分重要。
No air conditioning system can not be regarded loader a complete machine, driving the loader driver friends without refrigeration environment when bound to have discomfort, so easy to increase the operating risk. Learn the basics of air-conditioning system loader, loader air conditioning system to ensure stable cooling, create a cool and comfortable driving environment, Shandong loader driver friends is very important.

现代装载机上使用的空调系统都采用一种称为蒸发压缩制冷系统的方法，这种系统由压缩机、冷凝器、储液干燥瓶、膨胀阀和蒸发器组成。这些组件通过铝管或者胶管连接起来，制冷剂置于这个密封的管路系统内（制冷循环）。
Modern air-conditioning systems use a method of the loader are used vapor compression refrigeration system is referred to, this system consists of a compressor, a condenser, a receiver drier bottle, consisting of an expansion valve and an evaporator. These components are connected together by tubes or hoses, the refrigerant is placed in the closed piping system (refrigeration cycle).

空调压缩机由发动机驱动旋转，压缩机排出的高温、高压制冷剂蒸气，通过高压软管进入冷凝器，由于高温高压制冷剂蒸气温度高于车外的空气温度，因此借助冷凝风扇使冷凝器中制冷剂蒸气的热量被车外空气带走，使高温高压的制冷剂蒸气冷凝成较高温度的高压液体，通过高压软管流入干燥瓶，经干燥和过滤后，流过膨胀阀。
Air conditioning compressor driven by an engine rotates, the compressor discharge temperature, the high pressure refrigerant vapor to the condenser through the high pressure hose because of the high temperature high pressure refrigerant vapor is higher than the temperature of the outside air temperature, by means of condensation in the condenser fan heat of the refrigerant vapor is taken outside air, so that high temperature and pressure refrigerant vapor is condensed into high temperature high pressure liquid flows into the high pressure hose through the drying bottle, dried and filtered, flows through the expansion valve.

在膨胀阀的节流作用下，制冷剂变成低温、低压的液体而进入空调蒸发器，在定压下汽化并吸收蒸发器管外空气的热量，使流经蒸发器的车厢内循环空气的温度降低成为冷气，通过鼓风机送入车厢内，降低车内的空气温度。气化后的制冷剂蒸气，由压缩机吸入进行压缩，又变成高温、高压的制冷剂气体，通过高压软管压入冷凝器，完成了空调系统的一个制冷循环。
In the throttling expansion valve, the refrigerant becomes a low temperature and low pressure liquid into the air conditioner evaporator, circulating air in the constant pressure to vaporize and tube evaporator absorbing heat from air, flowing through the evaporator of the compartment lowering the temperature of the cold air through the blower into the inside, reducing the temperature of the air inside the vehicle. The refrigerant vapor vaporized by the compressor suction compression, and a high temperature, high pressure refrigerant gas, the pressure to the condenser via the high

pressure hose, to complete a refrigeration cycle of the air conditioning system.
