What is the purpose of the electric solenoid valve in a liquid feed system?

The primary purpose of the electric solenoid valve in a liquid feed system is to control liquid flow. This type of valve functions as an automated gate, opening or closing based on electrical signals. When activated, it allows the refrigerant to flow through the system, ensuring that liquid refrigerant is delivered to the evaporator or other necessary components when required. This precise control of the flow is essential for maintaining optimal system performance, enhancing efficiency, and preventing issues such as flooding or starvation of the evaporator.

The solenoid valve's ability to respond quickly to control signals is key in managing the refrigeration cycle effectively, contributing to overall system reliability and performance. In contrast, the other options refer to functions that do not align with the direct role of the solenoid valve in a liquid feed system.
