The excess energy = 2 741.7 - 2 706.7 = 35 kJ/kg, and this is used to raise the temperature of the steam from the saturation temperature of 120 °C to 136 °C. The degree of superheat can be determined either by using superheated steam tables, or by using a Mollier chart.

Understanding Superheat in HVAC. Superheat, a critical aspect of an HVAC system, involves heat absorption and the use of refrigerants like freon. This process impacts the temperature regulation and the suction capabilities of your system, with a key role played by the liquid line. Let’s delve deeper into what superheat is, how it works, its ...Subcooling is beneficial because it prevents the liquid refrigerant from changing to a gas before it gets to the evaporator. Pressure drops in the liquid piping and vertical risers can reduce the refrigerant pressure to the point where it will boil or "flash" in the liquid line. This change of phase causes the refrigerant to absorb heat before ...This video contains a solution on how to calculate the degree of superheat considering the saturation and superheated steam tables.The excess energy = 2 741.7 - 2 706.7 = 35 kJ/kg, and this is used to raise the temperature of the steam from the saturation temperature of 120 °C to 136 °C.

Superheat is a way to ensure that the system is boiling off all of the liquid before it exits the evaporator.Delta T = 77°F – 56°F = 21°F. We can see that delta T is 21°F. This is normal delta T. The normal delta T range is between 18°F and 22°F. The HVAC school refers to this as “It should be 20°F, of course” lazy rule. Now, normal delta T doesn’t necessarily mean that everything is alright with your AC unit.
