The Sensible Heat Ratio (SHR) in air conditioning is the ratio of:
- Sensible heat load to total heat load
- Latent heat load to sensible heat load
- Total heat load to sensible heat load
- Sensible heat load to latent heat load
Answer
A. Sensible heat load to total heat load
Solution
SHR = Qs/(Qs + QL).
