What is the primary function of a compressor in an A/C system?

The primary function of a compressor in an air conditioning system is to compress the refrigerant and circulate it throughout the system. This is a critical role because it allows the refrigerant to transition from a low-pressure gas to a high-pressure gas, which is essential for the refrigeration cycle to function effectively.

Once the refrigerant is compressed, it increases in temperature and pressure, enabling it to flow through the condenser coils where it releases heat to the outside environment. This process is fundamental for the cooling effect within the indoor space. The compressor, therefore, acts as the heart of the A/C system, facilitating the movement and transformation of refrigerant, ensuring efficient heat exchange and cooling.

In this context, the other options do not encapsulate the main duty of the compressor. The evaporator role is to absorb heat, filtering impurities is performed by air filters or purifiers, and the distribution of cooled air is handled by fans and ductwork, rather than the compressor itself. Understanding the specific function of the compressor is vital for diagnosing and maintaining air conditioning systems effectively.
