What is the difference between fixed-displacement and variable-displacement car air conditioners?

[VanMelanie]

The differences between fixed-displacement and variable-displacement car air conditioners are: 1. Different driving methods: Fixed-displacement air conditioners are driven by fixed power output; variable-displacement ones operate via variable frequency drives. 2. Different exhaust capacities: Variable-displacement can automatically adjust power output according to set temperature; fixed-displacement increases with engine speed. 3. Different energy consumption: Variable-displacement consumes less energy than fixed-displacement. Relevant information about car air conditioners: 1. Car air conditioner: Refers to the air conditioning device installed in vehicles. 2. Function: Can cool, heat, ventilate and purify air in the cabin, providing passengers with a comfortable environment, reducing driver fatigue and improving driving safety. Air conditioning systems have become one of the indicators for measuring whether a car is fully equipped.
