Question 1 of 205eccef9dbacbc34ba4d45f80

On a modern refrigerated container unit employing suction modulation for the purposes of capacity control and capacity limitation, what happens when the applied voltage and current draw associated with the normally open (NO) suction modulation valve located in the suction line both increase?

🔍 Key Concepts

• Normally open (NO) solenoid valve behavior when voltage/current increase • Location and function of a suction modulation valve in the suction line between the evaporator outlet and the compressor inlet • How flow restriction in the suction line affects pressure upstream (evaporator) vs downstream (compressor suction)

💭 Think About

• If a normally open valve is powered more strongly, does it tend to move toward a more open or more closed position? • When you partially close a valve in a line, what happens to the pressure on the upstream side of the restriction compared to the downstream side? • In a refrigeration system, which side of this valve corresponds to evaporator pressure and which side corresponds to suction (compressor inlet) pressure?

✅ Before You Answer

• Confirm that a normally open (NO) valve is fully open with no power and moves toward closed as voltage/current increase • Determine which line pressure is measured just after the evaporator and which is measured at the compressor suction • Check whether a greater restriction in the suction line will make upstream pressure go up or down, and downstream pressure go up or down
