What is the main purpose of using flow switches in refrigeration systems?

The primary role of flow switches in refrigeration systems is to ensure safety during operation. These devices monitor the flow of refrigerant or coolant within the system. If there is a disruption in flow, which could indicate a blockage or malfunction, the flow switch will trigger an alarm or shut down the system to prevent damage. This is crucial because insufficient flow can lead to overheating, pressure build-up, or even failure of critical components. Ensuring continuous flow helps maintain safe operating conditions, protecting both the equipment and the operator.

While other aspects like efficiency and performance may be enhanced indirectly through safe operational practices, the fundamental purpose of flow switches is centered around safety and protection.
