The formula to calculate the Superheat (SH) is:
\[ SH = CT - ST \]
Where:
Superheat is the difference between the actual temperature of the vapor refrigerant at the compressor inlet and the saturation temperature of the refrigerant. It is an important parameter in HVAC systems to ensure efficient operation and to prevent liquid refrigerant from entering the compressor.
Let's assume the following values:
Using the formula to calculate the Superheat (SH):
\[ SH = 55 - 40 = 15 \text{ °F} \]
The Superheat (SH) is 15 °F.
