1. What is Aircon Capacity per Square Meter?

Definition: This calculator estimates the required air conditioning capacity in BTU/h based on room area in square meters.

Purpose: It helps determine the appropriate air conditioner size needed to effectively cool a given space.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q_{btu} \) — Required aircon capacity (BTU/h)
• \( A_{room} \) — Room area (square meters)

Explanation: The room area is multiplied by 44.6 BTU/h per square meter, which is a standard value for moderate climate conditions.

3. Importance of Proper Aircon Sizing

Details: Correct aircon sizing ensures energy efficiency, proper cooling performance, and prevents excessive wear on the unit.

4. Using the Calculator

Tips: Simply enter the room area in square meters. The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: Why 44.6 BTU/h per square meter?
A: This is a standard value for moderate climates. It may vary based on insulation, sunlight exposure, and climate conditions.

Q2: Should I round up the calculated capacity?
A: Yes, it's recommended to choose the next available standard aircon size above your calculated value.

Q3: What factors might require increasing the capacity?
A: High ceilings, large windows, poor insulation, or hot climates may require 20-30% more capacity.

Q4: What if my room is irregularly shaped?
A: Calculate the total area and use that. For L-shaped rooms, calculate each rectangle separately and sum the results.

Q5: Does this account for room height?
A: The standard calculation assumes normal ceiling heights (2.4-2.7m). For higher ceilings, increase capacity proportionally.
