What is the purpose of the flow-limiting venturi in the air conditioning system?

Explanation:
The flow-limiting venturi is used to regulate how much air the air conditioning system receives. By constricting the passage through a narrow throat, it creates a controlled pressure drop that limits the amount of air drawn from the cross-wing manifold and directed to the system components. This keeps the airflow within the designed range, preventing overloading of components and ensuring stable, proper operation of the cooling system. It’s not a filter and doesn’t directly reduce refrigerant temperature; its primary role is airflow control.
