What is the role of the compressor control valve?

The function being tested is how the compressor receives refrigerant to be compressed. The compressor control valve directs the low‑pressure refrigerant from the evaporator into the compressor so it can be squeezed to a higher pressure. It acts as the intake control, opening during the suction phase to admit gas and closing during compression to prevent backflow, ensuring the refrigerant moves in the correct direction through the compressor. This role is distinct from metering refrigerant to the evaporator (that’s the job of the metering device), from sensing suction pressure (which is handled by sensors), and from changing the compressor’s stroke or displacement.
