Given that valve "14" is the king solenoid...

🔍 Key Concepts

• Trace the liquid line from the king solenoid valve "14" forward to see how the system branches to the two evaporators. • Identify which evaporator is the chill box and which is the freeze box by looking for any suction pressure‑regulating/back‑pressure valve in the suction line. • Note the location of the individual solenoid valves ("28" and "36") in relation to their respective thermostatic expansion valves and evaporator coils.

💭 Think About

• Follow the refrigerant flow from valve "14" toward the right side of the drawing: which components and valves does it encounter before reaching valves "28" and "36"? • One of the evaporators must operate at a higher evaporating pressure/temperature (chill box). Which evaporator’s suction line includes a pressure‑regulating device to keep its pressure from dropping too low? • Once you know which evaporator is the chill box, which numbered solenoid controls liquid flow to that evaporator versus the other one?

✅ Before You Answer

• Be sure you can clearly point to the two separate evaporator coils and their suction return paths on the diagram. • Confirm which valve symbol represents a solenoid valve (often marked with an "S") and that "28" and "36" match this symbol. • Before choosing, verify you have labeled in your mind: (a) chill box evaporator, (b) freeze box evaporator, and (c) which solenoid sits in each liquid feed line.

Given that valve "14" is the king solenoid valve, which of the following statements is true? Illustration RA-0012

Valve "28" is the chill box solenoid, and valve "36" is the freeze box solenoid.

Valves "28" and "36" are both chill box solenoids.

Valve "36" is the chill box solenoid, and valve "28" is the freeze box solenoid.

Valves "28" and "36" are both freeze box solenoids.
