SHR Formula
The sensible heat ratio (SHR) can be calculated using the formula:
\[ \text{SHR} = \frac{q_s}{q_t} \]
Where:
- \( q_s \) is the sensible heat (kW)
- \( q_t \) is the total heat (kW)
Definition: What is Sensible Heat Ratio (SHR)?
The sensible heat ratio (SHR) measures the proportion of sensible heat (which affects temperature) to the total heat processed by an evaporator. An SHR of 1 indicates that all energy is used for cooling with no dehumidification (which is not feasible in real-world applications).
Example Calculation
If the sensible heat is 4 kW and the total heat is 5 kW, then:
\[ \text{SHR} = \frac{4}{5} = 0.8 \]
This indicates that 80% of the energy is used for sensible cooling, while 20% is for latent cooling (dehumidification).
Importance and Applications
Understanding the SHR is critical for designing HVAC systems, especially when balancing cooling and dehumidification. Systems with different SHRs are tailored to different climates and applications.
