1. What is Heat Load Calculation?

Heat load calculation determines the amount of heat energy that needs to be removed from a space to maintain comfortable conditions. It's essential for proper AC system sizing and efficient operation.

2. How Does the Calculator Work?

The calculator uses the heat load equation:

Where:

• \( Q \) — Total heat load (BTU/h)
• \( \Sigma \text{Gains} \) — Sum of all heat gains in the space

Explanation: The equation accounts for all sources of heat gain including solar radiation, occupants, equipment, and ventilation.

3. Importance of Heat Load Calculation

Details: Accurate heat load calculation is crucial for proper AC system sizing, energy efficiency, and maintaining comfortable indoor conditions.

4. Using the Calculator

Tips: Enter the required parameters such as area, number of occupants, equipment heat output, and other relevant factors. All values must be valid and realistic.

5. Frequently Asked Questions (FAQ)

Q1: Why is accurate heat load calculation important?
A: Proper calculation ensures the AC system is correctly sized, preventing energy waste and maintaining comfort.

Q2: What factors contribute to heat gain?
A: Solar radiation through windows, internal heat from people and equipment, infiltration, and ventilation air.

Q3: How often should heat load calculations be performed?
A: Whenever there are significant changes to the space, or when installing new AC equipment.

Q4: What's the difference between sensible and latent heat?
A: Sensible heat affects temperature, while latent heat affects humidity levels.

Q5: Can this calculator be used for commercial spaces?
A: This calculator provides basic estimates. Commercial spaces typically require more detailed manual J calculations.
