裝載機空調系統工作原理

沒有空調系統的裝載機不能算是一臺完整的機器，司機朋友們在無制冷的環境中駕駛裝載機的時候必然會有種種不適，這樣容易增加操作風險。了解裝載機空調系統基礎知識，保證裝載機空調系統能夠穩定制冷，營造一個涼快舒適的駕駛環境，對山東裝載機司機朋友來說十分重要。
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.

現代裝載機上使用的空調系統都采用一種稱為蒸發壓縮制冷系統的方法，這種系統由壓縮機、冷凝器、儲液干燥瓶、膨脹閥和蒸發器組成。這些組件通過鋁管或者膠管連接起來，制冷劑置于這個密封的管路系統內（制冷循環）。
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).

空調壓縮機由發動機驅動旋轉，壓縮機排出的高溫、高壓制冷劑蒸氣，通過高壓軟管進入冷凝器，由于高溫高壓制冷劑蒸氣溫度高于車外的空氣溫度，因此借助冷凝風扇使冷凝器中制冷劑蒸氣的熱量被車外空氣帶走，使高溫高壓的制冷劑蒸氣冷凝成較高溫度的高壓液體，通過高壓軟管流入干燥瓶，經干燥和過濾后，流過膨脹閥。
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.

在膨脹閥的節流作用下，制冷劑變成低溫、低壓的液體而進入空調蒸發器，在定壓下汽化并吸收蒸發器管外空氣的熱量，使流經蒸發器的車廂內循環空氣的溫度降低成為冷氣，通過鼓風機送入車廂內，降低車內的空氣溫度。氣化后的制冷劑蒸氣，由壓縮機吸入進行壓縮，又變成高溫、高壓的制冷劑氣體，通過高壓軟管壓入冷凝器，完成了空調系統的一個制冷循環。
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.
