1. What is the Daikin Heat Load Calculation?

The Daikin Heat Load calculation estimates the thermal energy required to maintain comfortable conditions in a space. It considers both the area's characteristics and occupant heat contributions.

2. How Does the Calculator Work?

The calculator uses the Daikin Heat Load equation:

Where:

• \( Area \) — Floor area in square meters
• \( Factor \) — Heat load factor per square meter (W/m²)
• \( Occupants \) — Number of people in the space
• \( Heat \) — Heat contribution per person (W/person)

Explanation: The equation calculates the total heat load by combining the heat gain from the building envelope (area × factor) with the heat generated by occupants.

3. Importance of Heat Load Calculation

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

4. Using the Calculator

Tips: Enter the area in square meters, appropriate factor for your space, number of occupants, and their heat contribution. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are typical values for the heat load factor?
A: Factors typically range from 50-150 W/m² depending on insulation, orientation, and climate.

Q2: How much heat does a person typically generate?
A: An average person at rest generates about 100W, increasing with activity level.

Q3: Should I include other heat sources?
A: For complete calculations, include equipment, lighting, and solar gains. This is a simplified version.

Q4: How does this relate to cooling capacity?
A: The calculated heat load helps determine the required cooling capacity of HVAC systems.

Q5: What about latent heat loads?
A: This calculator focuses on sensible heat. Professional calculations should consider both sensible and latent loads.
