What are the main components of a car air conditioning system?

A car air conditioning system is generally composed of the compressor, electronic control clutch, condenser, evaporator, expansion valve, receiver-drier, pipelines, condenser fan, vacuum solenoid valve, idle speed controller, and control system. Below is a partial introduction to car air conditioning: 1. Air conditioning circuit: Car air conditioning is divided into high-pressure pipelines and low-pressure pipelines. The high-pressure side includes the compressor output side, high-pressure pipelines, condenser, receiver-drier, and liquid pipelines; the low-pressure side includes the evaporator, accumulator, return pipelines, compressor input side, and compressor oil sump. 2. Precautions: The car air conditioning should be turned on weekly even in winter to ensure lubrication of all components. Additionally, the dust filter should be checked regularly, and if too much dust accumulates, it should be replaced promptly. The condenser located at the front of the car should ideally be rinsed with a high-pressure water gun during each car wash to prevent debris from clogging the cooling fins and affecting heat dissipation efficiency.
I used to think a car's air conditioning was just one component, but after driving for several years, I realized it has several core parts: the compressor acts like the heart, pumping out the refrigerant; the condenser, located at the front of the engine bay, dissipates heat; the evaporator inside the dashboard cools the air; the expansion valve controls the refrigerant flow; and, of course, there's the refrigerant itself that transfers heat. Additionally, the control panel lets me adjust the temperature and airflow, the fan blows the air, and the filter traps dust particles. All these components work together to blow cool air. If the filter isn’t replaced regularly, it can clog and reduce efficiency—I’ve learned to clean it every six months to maintain freshness.
