Question 1 of 27070

The presence of gas in the liquid line of a refrigeration system is undesirable and can be eliminated by what action?

🔍 Key Concepts

• Behavior of refrigerant as it leaves the condenser and travels in the liquid line • Meaning and purpose of subcooling in a refrigeration system • What happens when gas/vapor is present in a line that is supposed to carry only liquid refrigerant

💭 Think About

• Ask yourself: In a properly operating system, should the liquid line from the condenser to the expansion valve contain any vapor? Why or why not? • Which option would most directly ensure that the refrigerant in the liquid line stays below its saturation temperature at that pressure? • Consider what effect each choice would have on the refrigerant’s state (liquid vs vapor), not just its location.

✅ Before You Answer

• Verify which choice actually changes the refrigerant’s temperature relative to its saturation temperature at the liquid-line pressure. • Check whether any option would just change the geometry/location of components without directly changing the refrigerant’s phase. • Confirm which action is specifically associated in textbooks with preventing flash gas in the liquid line.
