Window Aircon Formula:
| From: | To: |
The Window Aircon Calculator determines the appropriate horsepower (HP) needed for a window air conditioner based on room area in square meters. Proper sizing ensures efficient cooling and energy consumption.
The calculator uses the window aircon formula:
Where:
Explanation: This formula provides a general guideline for selecting the appropriate air conditioner capacity based on room size, with 18 square meters per horsepower being a standard conversion factor.
Details: Correct air conditioner sizing is crucial for energy efficiency, optimal cooling performance, and preventing excessive wear on the unit. An undersized unit will struggle to cool the space, while an oversized unit will cycle on and off frequently.
Tips: Enter the room area in square meters. Measure the length and width of the room and multiply them to get the area. For irregularly shaped rooms, divide into rectangular sections and sum the areas.
Q1: What if my room has high ceilings?
A: For rooms with ceilings higher than 2.7 meters, consider increasing the calculated HP by 10-15% to account for the additional volume.
Q2: Does room orientation affect aircon sizing?
A: Yes, rooms with large windows facing the sun may require additional cooling capacity. Add 10% for south-facing rooms in hot climates.
Q3: What about rooms with many occupants or heat-generating appliances?
A: For rooms with more than 2 people regularly or with computers, refrigerators, or other heat sources, increase the calculated HP by 0.5-1 HP.
Q4: Is this calculation suitable for all room types?
A: This provides a basic guideline. Kitchens, server rooms, and rooms with poor insulation may require professional assessment for accurate sizing.
Q5: What are common HP sizes available?
A: Common window aircon sizes include 0.5 HP, 1 HP, 1.5 HP, 2 HP, and 2.5 HP. Always round up to the nearest available size.
