HVAC Energy Calculator

Formula

The formula to calculate HVAC Energy is:

\[ E = V \cdot d \cdot C_p \cdot \Delta T \]

Where:

\(E\) is the HVAC energy (Joules)
\(V\) is the total volume of air (m³)
\(d\) is the density of air (1.225 kg/m³)
\(C_p\) is the specific heat of air (1000 J/kg-°C)
\(\Delta T\) is the change in temperature (°C)

What is HVAC Energy?

HVAC Energy refers to the amount of energy required to heat or cool a certain volume of air by a specific temperature change. This is an important metric in designing and optimizing heating, ventilation, and air conditioning (HVAC) systems to ensure efficient energy usage and maintain desired indoor conditions.

Example Calculation

Let's assume the following values:

Total Volume of Air (V) = 100 m³
Change in Temperature (ΔT) = 10 °C

Using the formula:

\[ E = 100 \, \text{m}^3 \times 1.225 \, \text{kg/m}^3 \times 1000 \, \text{J/kg-°C} \times 10 \, °C = 1.225 \times 10^6 \, \text{J} \]

The HVAC Energy is \(1.225 \times 10^6\) Joules.
