🔍 Key Concepts

• Trace the refrigerant flow to and from the evaporator associated with valve 29 to see if it is on the liquid line or the suction line. • Compare the symbol and location of valve 29 with the nearby valve marked with an S (solenoid) and with the valve at the inlet to the evaporator (thermostatic expansion valve). • Remember how a chill box and a freeze box are usually controlled in a multi‑evaporator system, especially where an evaporator pressure regulating (EPR) valve is normally installed.

💭 Think About

• Follow the piping from evaporator K and evaporator J: which evaporator’s outlet line passes through valve 29 before joining the suction header? • Is valve 29 controlling the flow of liquid refrigerant into an evaporator, or is it controlling the suction pressure leaving an evaporator? How does that relate to each answer choice? • In a system that has both a chill box and a freeze box, which one typically needs its evaporator pressure held higher so it does not get too cold when the other box is pulling the suction pressure down? Where would that valve be drawn?:

✅ Before You Answer

• Verify whether valve 29 is drawn on the suction side (vapor line returning to the compressor) or on the liquid side; this immediately rules out some options. • Confirm which nearby valve is clearly labeled with S (solenoid) so you don’t confuse the solenoid with valve 29. • Identify which evaporator (chill or freeze) is connected through valve 29 by following the numbered lines; this tells you whether the valve’s function matches pressure regulating or thermostatic expansion for that specific box.
