One common use of a solenoid valve is to control the flow of liquid refrigerant to multiple sections of the evaporator. In this application, a valve is installed in the liquid line, upstream of the expansion valve for each individually controlled section of the evaporator coil.

Using the example of a face-split evaporator coil, at lower loads a solenoid valve may be used to shut off the flow of liquid refrigerant to the top section of the coil. A portion of the air passes through the active lower section and is cooled, while the rest of the air passes through the inactive top section and remains unconditioned. The two airstreams mix downstream of the coil. At higher loads, both sections of the coil are activated.

Another common use of a solenoid valve is to enable system pump-down and prevent the refrigerant from migrating through the system when the compressor is shut off. In this application, a single solenoid valve is installed in the liquid line, upstream of all expansion valves.
