🔍 Key Concepts

• Relationship between temperature and pressure in a refrigeration system evaporator (for a given refrigerant) • How saturation pressure of a refrigerant changes with evaporating temperature • What happens to evaporator pressure when you want a coil to be colder than another coil on the same system

💭 Think About

• Think about the pressure–temperature chart for a common refrigerant: as the evaporating temperature goes down, does the corresponding saturation pressure go up or down? • If one evaporator is maintaining a much colder space than another, what must be different inside that evaporator to achieve the lower temperature? • On a system with multiple evaporators and one compressor, which component really determines the pressure level in the low side of the system?

✅ Before You Answer

• Review a refrigerant P–T chart and compare the pressure at a cold evaporating temperature vs. a warmer evaporating temperature. • Confirm whether all evaporators on the same suction line actually share the same suction pressure, or if they each run at different pressures. • Verify what the thermal expansion valve (TXV) actually controls (superheat vs. pressure) in normal refrigeration system design.
