Aircon Capacity Formula:
From: | To: |
Definition: This calculator estimates the required air conditioning capacity (in BTU/h) based on room area in square meters.
Purpose: It helps homeowners and HVAC professionals determine the appropriate air conditioner size for a given room space.
The calculator uses the formula:
Where:
Explanation: The room area is multiplied by 44.6 BTU/h per square meter, which is a standard conversion factor for moderate climates.
Details: Correct aircon sizing ensures energy efficiency, proper cooling, and prevents short-cycling or excessive wear on the unit.
Tips: Simply enter the room area in square meters. The calculator will output the recommended aircon capacity in BTU/h.
Q1: Why 44.6 BTU/h per square meter?
A: This is a standard conversion factor for moderate climates. It may need adjustment for very hot or humid areas.
Q2: What if my room has high ceilings?
A: For ceilings higher than 2.7 meters, multiply the result by (ceiling height/2.7).
Q3: Does this account for windows or insulation?
A: No, this is a basic calculation. Add 10-20% for sunny rooms or poor insulation.
Q4: What about rooms with many occupants or heat-generating appliances?
A: Add approximately 600 BTU/h per additional person or major heat source.
Q5: How do I convert BTU/h to kW?
A: Divide BTU/h by 3412 to get kilowatts (kW).
