1. What is a Commercial Air Conditioning Calculator?

Definition: This calculator estimates the power consumption of commercial air conditioning systems based on room area and EER rating.

Purpose: It helps HVAC professionals and facility managers determine the energy requirements for cooling commercial spaces.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Power consumption (kilowatts)
• \( A_{room} \) — Room area (square meters)
• 50 — Commercial cooling load factor (BTU/h per m²)
• 3412 — Conversion factor from BTU/h to kW
• \( EER \) — Energy Efficiency Ratio (dimensionless)

Explanation: The formula calculates the power needed to maintain commercial cooling loads, accounting for system efficiency.

3. Importance of Commercial AC Calculation

Details: Accurate power estimation ensures proper system sizing, energy efficiency, and cost-effective operation.

4. Using the Calculator

Tips: Enter the room area in square meters and the EER rating (default 3.5). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is EER?
A: Energy Efficiency Ratio measures how efficiently a cooling system operates (higher values = more efficient).

Q2: Why 50 BTU/h per m²?
A: This is a standard commercial cooling load factor accounting for higher occupancy, equipment, and lighting.

Q3: What's a typical EER for commercial units?
A: Modern commercial AC units typically have EER ratings between 3.0 and 5.0.

Q4: How does this differ from residential AC?
A: Commercial spaces use higher load factors (50 vs ~30 BTU/h/m²) due to greater heat generation.

Q5: Can I use this for server rooms?
A: No, server rooms require specialized calculations due to much higher equipment heat loads.
