 Difference between 5 different types of automobile air conditioning compressors:

• ‌‌Reciprocating Piston Type‌: ‌Mature technology, low cost‌. It can adapt to a wide range of pressures and cooling capacities, but has poor dynamic balance, complex structure, and requires extensive maintenance.

• ‌‌Rotary Piston Type: ‌Lightweight, few parts, small size, high reliability‌. However, it has a smaller displacement and is suitable for air conditioning systems with smaller cooling capacities.

• ‌‌Variable Displacement Compressor‌: Automatically adjusts power output according to set temperature‌. It controls the compression ratio based on changes in air conditioning pipeline pressure signals, automatically adjusting the outlet temperature. The compressor always works during cooling.

• ‌‌Scroll Type: Few accessories, small size, lightweight, high efficiency and stability‌. But its manufacturing cost is relatively high.

• ‌‌Fixed Displacement Compressor‌: The displacement increases proportionally with the engine speed‌. It cannot automatically change the power output and has a greater impact on engine fuel consumption.
