Enter the sensible heat and total heat values into the calculator to determine the Sensible Heat Ratio (SHR).
Sensible Heat Ratio Calculation Formula
The following formula is used to calculate the Sensible Heat Ratio (SHR).
SHR = Sensible Heat / Total Heat
Variables:
- Sensible Heat is the heat exchanged by a thermodynamic system that changes the temperature without changing the phase (BTU/hr)
- Total Heat is the sum of sensible heat and latent heat (BTU/hr)
To calculate the SHR, divide the sensible heat by the total heat.
What is Sensible Heat Ratio?
The Sensible Heat Ratio (SHR) is a metric used to describe the proportion of sensible heat to the total heat in an HVAC system. It is crucial for understanding how much of the heat being added or removed is changing the air temperature rather than causing phase changes like condensation or evaporation. This ratio is significant in designing and optimizing HVAC systems to ensure efficient temperature regulation and comfort.
How to Calculate Sensible Heat Ratio?
The following steps outline how to calculate the Sensible Heat Ratio using the given formula.
- First, determine your sensible heat based on your HVAC system measurements.
- Next, determine the total heat, which is the sum of sensible heat and latent heat.
- Use the formula from above: SHR = Sensible Heat / Total Heat.
- Finally, calculate the SHR by plugging in the values.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Sensible Heat = 15,000 BTU/hr
Total Heat = 20,000 BTU/hr
