The temperature of the refrigerant in the...

🔍 Key Concepts

• Relationship between pressure and temperature in a saturated refrigerant (inside the evaporator) • Where the evaporator coil is located in the system and what directly controls conditions inside it • Difference between factors that indirectly influence the evaporator and the one that has a direct, immediate effect on refrigerant temperature

💭 Think About

• Which one of these choices changes the refrigerant’s saturation temperature inside the evaporator at that moment? • Do components like the condenser water temperature or solenoid valve change the evaporator refrigerant temperature directly, or only by affecting other conditions first? • If you look at a pressure–temperature chart for the refrigerant, what is the main variable that sets the refrigerant temperature in the evaporator?

✅ Before You Answer

• Identify which option is directly inside or immediately connected to the evaporator conditions, not just elsewhere in the system • Ask: which factor could I read with a gauge and then look up on a P–T chart to find the evaporator temperature? • Eliminate any answer that is mainly about flow control or external cooling rather than the thermodynamic state of the refrigerant in the evaporator

The temperature of the refrigerant in the evaporator coil depends mostly upon what factor?

refrigerant pressure in the evaporator

cooling water temperature to the condenser

heat load in the refrigerator compartment

solenoid valve in the liquid line
