What is the function of a compressor?

Compressor is the power core of the air conditioner refrigeration system. It can increase the temperature and pressure of the inhaled low-temperature and low-pressure refrigerant vapor through compression, making the refrigerant inside move, and achieving the purpose of refrigeration through thermal work conversion. If the refrigeration system is compared to the human body system, the refrigeration compressor is one of the most important components of the refrigeration system, and it is the core and heart of the vapor refrigeration system. The compressor draws refrigerant vapor from the evaporator to ensure a certain evaporation pressure in the evaporator. After increasing the pressure, it compresses the low-pressure and low-temperature refrigerant vapor into high-pressure and high-temperature superheated vapor to create conditions for condensation at a higher temperature, transports and pushes the refrigerant to flow in the system, and completes the refrigeration cycle.
I've learned that the core function of the compressor is to compress the refrigerant gas into a high-pressure, high-temperature state, thereby initiating the cooling cycle of the air conditioning system. In my understanding, it's like the heart of a car's AC system because only through compression can the refrigerant be cooled and liquefied in the condenser, then decompressed and evaporated via the expansion valve to release cold air, ultimately cooling the car interior. Without the compressor, the AC would fail, making summer drives unbearable.
The compressor is typically driven by the engine belt, so its operation slightly increases fuel consumption, especially noticeable during traffic jams. Many modern vehicles now come equipped with variable displacement compressors that intelligently adjust compression levels to save fuel. However, prolonged use may lead to issues like loose belts or refrigerant leaks, resulting in noise or loss of cooling capacity, which requires immediate inspection.
Regular maintenance should focus on lubrication and sealing, along with periodic Freon refills to extend the compressor's lifespan and avoid breakdowns. Overall, it's a critical component ensuring driving comfort.
