What might be a consequence of blockages in an MVAC system?

• A. Increased airflow
• B. Reduced cooling performance
• C. Higher system pressure
• D. Lower operating costs

Answer: (B)

A blockage in an MVAC (Motor Vehicle Air Conditioning) system can significantly hinder its overall functionality. When airflow is obstructed—whether due to debris, kinks in the hoses, or a malfunctioning component—the system struggles to circulate refrigerant properly. This results in reduced cooling performance, as the air conditioning cannot effectively transfer heat away from the vehicle’s interior. Additionally, as the system works harder to compensate for the obstruction, it may lead to increased pressure on certain components, but the primary effect felt by the user will be that the cooling output diminishes. Therefore, recognizing this link between blockages and cooling efficiency is crucial for maintaining a well-functioning MVAC system. On the other hand, increased airflow, higher system pressure, and lower operating costs would not occur in this scenario, as blockages typically create a cascade of issues that are contrary to optimal performance.
