Aircon Horsepower Formula:
| From: | To: |
The Aircon Horsepower Calculator helps determine the appropriate air conditioning capacity needed for a room based on its area. This is particularly important in the Philippines where proper aircon sizing ensures energy efficiency and optimal cooling performance.
The calculator uses the standard Philippine aircon sizing formula:
Where:
Explanation: This formula is based on the standard calculation used in the Philippines where approximately 18 square meters of room area requires 1 horsepower of cooling capacity.
Details: Proper aircon sizing is crucial for energy efficiency, cost savings, and optimal comfort. An undersized unit will struggle to cool the room, while an oversized unit will cycle on and off frequently, wasting energy and not properly dehumidifying the air.
Tips: Measure your room's length and width in meters, multiply to get the area in square meters, and enter this value. The calculator will determine the recommended horsepower for your air conditioning unit.
Q1: Why is 18 m² per horsepower used in the Philippines?
A: This is a standard industry calculation that accounts for typical Philippine climate conditions, building materials, and average room insulation.
Q2: What if my room has high ceilings or many windows?
A: For rooms with high ceilings (above 2.7m), large windows, or direct sunlight exposure, you may need to add 0.5 HP to the calculated value.
Q3: Can I use this for commercial spaces?
A: This calculator is designed for residential rooms. Commercial spaces with higher occupancy or equipment may require different calculations.
Q4: What are common aircon horsepower sizes in the Philippines?
A: Common sizes are 0.5 HP, 1.0 HP, 1.5 HP, 2.0 HP, and 2.5 HP, suitable for rooms from 9 m² to 45 m² respectively.
Q5: Does room orientation affect aircon sizing?
A: Yes, rooms facing west that receive afternoon sun may require additional cooling capacity of about 10-15%.
