What is the function of a compressor?

The function of a compressor is to regulate the start-stop state of the air compressor. By adjusting the pressure in the air storage tank, it allows the air compressor to shut down and rest, which has a maintenance effect on the engine. Types of compressors include: 1. Positive displacement compressor; 2. Dynamic compressor; 3. Reciprocating compressor; 4. Rotary compressor. The working principle of a compressor is that the engine drives the compressor, causing the crankshaft to rotate, which drives the connecting rod to make the piston reciprocate, leading to changes in the cylinder volume. Due to the changes in pressure inside the cylinder, air enters the cylinder through the intake valve via the air filter. During the compression stroke, as the cylinder volume decreases, the compressed air passes through the exhaust valve and enters the air storage tank via the one-way valve in the exhaust pipe. When the exhaust pressure reaches the rated pressure, the pressure switch controls it to automatically shut down.
As a car enthusiast, I often tinker with the air conditioning system. The compressor is the engine of the entire refrigeration process. It compresses low-pressure gaseous refrigerant into high-pressure, high-temperature gas, which is then sent to the condenser for cooling, creating cold air through the cycle. Simply put, without it, the AC won’t blow cold air. During long drives, I’ve noticed that a malfunctioning compressor can cause the AC to suddenly fail, especially on hot summer stretches, leading to a rapid rise in cabin temperature—no joke. Common issues like belt slippage, insufficient refrigerant, or internal compressor wear can all reduce efficiency. I recommend having technicians check the belt tension and refrigerant levels during routine maintenance—preventive care is always better than a breakdown on the road. Remember, smooth compressor operation means a cooler AC and a safer, worry-free driving experience.
