Formula & worked example
SHR=Qs/(Qs+Ql)=Qs/Qt; Ql=Qt−Qs.
24 kW sensible plus 6 kW latent gives 30 kW total and SHR 0.80.

Sensible Heat Ratio Calculator — SHR, Sensible & Latent Load
Solve HVAC sensible heat ratio from sensible and latent or total capacity, and reverse-solve either load from SHR. Shows the complete sensible/latent split in kW and BTU/h.
Inputs
Live result
Calculated total 30 kW (102,364.25 BTU/h)
Calculated SHR 0.8 (80%)
Latent fraction 20%
From entered total + target SHR: sensible 24 kW
From entered total + target SHR: latent 6 kW
Assumptions & limits
- Loads must use the same energy-rate basis.
- SHR describes the load split; it does not by itself select a coil.
Frequently asked questions
What does this Sensible Heat Ratio Calculator calculate?
Solve HVAC sensible heat ratio from sensible and latent or total capacity, and reverse-solve either load from SHR. Shows the complete sensible/latent split in kW and BTU/h.
Can I use the result for final HVAC selection?
Use the result as a transparent engineering cross-check. Confirm final selections against measured design conditions, manufacturer data, applicable standards and local code.
Why are the assumptions shown?
HVAC shortcuts can look precise while hiding density, efficiency, free-area or pressure assumptions. MAXScanner keeps the governing inputs visible so the result can be audited.
