1. What is an Aircon BTU Calculator for Singapore?

Definition: This calculator estimates the cooling capacity (in BTU/h) needed for air conditioning based on room size and Singapore's tropical climate conditions.

Purpose: It helps homeowners and businesses determine the appropriate air conditioner size for optimal cooling and energy efficiency.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Cooling load (BTU/h)
• \( A \) — Room area (square feet)
• \( \text{BTU/ft}^2 \) — Cooling requirement per square foot (typically 25 BTU/h·ft² for Singapore)
• \( F \) — Adjustment factor for room conditions (default 1.2 for Singapore)

Explanation: The base cooling requirement is adjusted for Singapore's high humidity, heat, and other environmental factors.

3. Importance of Proper BTU Calculation

Details: Correct sizing ensures efficient cooling, prevents excessive energy consumption, and extends aircon lifespan by avoiding overworking.

4. Using the Calculator

Tips: Enter room area in square feet, BTU/ft² (default 25 for Singapore), and adjustment factor (default 1.2). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is the BTU/ft² higher for Singapore?
A: Singapore's tropical climate with high humidity and temperatures requires more cooling power per square foot.

Q2: What's the adjustment factor for?
A: It accounts for additional heat sources (windows, appliances, people) and Singapore's constant warm temperatures.

Q3: When should I increase the adjustment factor?
A: For rooms with many windows (1.3), kitchens (1.4), or server rooms (1.5+).

Q4: How do I convert room size from meters to feet?
A: Multiply square meters by 10.764 to get square feet.

Q5: Should I round up the calculated BTU?
A: Yes, choose the next available standard aircon size (9000, 12000, 18000 BTU etc.).
