The formula to calculate the Heat Recovery is:
\[ \text{HR} = 1.08 \cdot Q \cdot \Delta T \cdot \frac{E}{100} \]
Where:
Heat recovery refers to the process of capturing and reusing heat from a system that would otherwise be lost. This is commonly used in HVAC systems to improve energy efficiency by recovering heat from exhaust air and using it to preheat incoming fresh air. The heat recovery efficiency indicates how effectively the system can capture and reuse this heat.
Let's consider an example:
Using the formula to calculate the Heat Recovery:
\[ \text{HR} = 1.08 \cdot 500 \cdot 20 \cdot \frac{70}{100} = 7560 \text{ BTU/h} \]
This means that the heat recovery for this scenario is 7560 BTU/h.
