What is the function of a compressor?

The function of a compressor is to regulate the start-stop state of the air compressor, allowing it to rest by adjusting the pressure in the air storage tank, which has a maintenance effect on the engine. The working principle of a compressor is to draw refrigerant from the low-pressure area, compress it, and then send it to the high-pressure area for cooling and condensation. The heat is dissipated into the air through the radiator, and the refrigerant changes from a gaseous state to a liquid state, with an increase in pressure. The types of compressors include: swash plate compressors, vane compressors, scroll compressors, and crankshaft connecting rod compressors. The causes of compressor damage are: 1. Damage to the electromagnetic clutch inside the air conditioning compressor or internal wear of the compressor; 2. Refrigerant leakage; 3. Damage to the compressor capacitor.
As an ordinary driver with many years of experience, I believe the compressor plays a heart-like role in a car's air conditioning system. It is primarily responsible for compressing the refrigerant gas into a high-pressure liquid and pushing it into the cycle. Simply put, the refrigerant first absorbs heat and evaporates into a gas at low pressure, then the compressor acts like a pump to squeeze it into high pressure and sends it to the condenser for cooling. Next, the liquid flows into the evaporator, expands, absorbs heat, and blows out cold air to cool us down. Without it in the summer, the car would feel like an oven, and the AC wouldn’t provide any relief. Once, my compressor broke while driving, leaving me sweating profusely and nearly suffering from heatstroke—it seriously compromised safe driving. During routine maintenance, remember to check the compressor oil level and belt wear. Oil leaks or loose belts can paralyze the system. Don’t ignore unusual noises, as they are early warning signs. A good compressor can keep the AC running efficiently for over a decade, so choosing a reliable brand is crucial.
