Evaporation in the condenser and condensation in the evaporator
Evaporation in the evaporator and condensation in the condenser
Sublimation in the compressor and freezing in the receiver
Condensation in both heat exchangers
Question 4
Superheat in a refrigeration system is defined as:
The temperature of the liquid below its saturation temperature
The temperature of the vapour above its saturation temperature at that pressure
The total pressure rise across the compressor
The difference between condensing and evaporating pressures
Question 5
Subcooling at the condenser outlet is important because it:
Ensures only liquid refrigerant reaches the metering device, preventing flash gas in the liquid line
Guarantees the compressor receives liquid refrigerant
Reduces the suction superheat to zero
Increases the discharge temperature for better oil return
