Where is the orifice tube located within the A/C system?

The orifice tube is a critical component in the A/C system that helps regulate the flow of refrigerant between the condenser and evaporator. Located in this specific area, it serves as a metering device, allowing the refrigerant to expand and change from a high-pressure liquid to a low-pressure gas before entering the evaporator. This process is essential for the A/C system to effectively cool the vehicle interior.

By being positioned between the condenser and evaporator, the orifice tube ensures that the refrigerant, after being condensed and cooled in the condenser, is appropriately metered into the evaporator. This facilitates efficient heat exchange and cooling, which is pivotal for maintaining the desired temperature within the passenger cabin.

The other locations mentioned, such as between the evaporator and compressor, near the accumulator, or within the compressor, would not allow for the proper function and regulation of refrigerant flow essential for the cooling process. Each of these components plays a distinct role in the A/C system; thus, knowing the correct placement of the orifice tube is crucial for understanding how the entire air conditioning system operates.
