Aircon HP Calculation Formula:
| From: | To: |
The Aircon HP Per Sqm calculation estimates the required air conditioning horsepower based on room area. This formula provides a quick reference for selecting appropriately sized air conditioning units for different room sizes.
The calculator uses the simple formula:
Where:
Explanation: This formula assumes a standard cooling requirement of approximately 100 watts per square meter, with 1 HP equivalent to about 1000 watts of cooling capacity.
Details: Proper aircon sizing is crucial for energy efficiency, optimal cooling performance, and equipment longevity. Undersized units struggle to cool spaces, while oversized units cycle frequently, reducing efficiency and comfort.
Tips: Enter the total room area in square meters. For irregular rooms, calculate the area by multiplying length by width. Consider additional factors like ceiling height, insulation, and heat-generating appliances for more accurate sizing.
Q1: Is this calculation accurate for all room types?
A: This provides a basic estimate. Rooms with high ceilings, poor insulation, or significant heat sources may require additional capacity.
Q2: What if my room has unusual dimensions?
A: Calculate the total floor area. For L-shaped rooms, calculate each rectangular section separately and sum the areas.
Q3: How does ceiling height affect the calculation?
A: Rooms with ceilings higher than 2.7 meters may require additional capacity. Consider increasing the calculated HP by 10-20% for high ceilings.
Q4: What about rooms with lots of windows?
A: Sun-facing rooms or those with large windows may need 10-15% more capacity to account for solar heat gain.
Q5: Should I round up or down when choosing an aircon unit?
A: Generally round up to the nearest standard unit size (0.5 HP, 1 HP, 1.5 HP, etc.) for better performance and efficiency.
