Aircon HP Calculation Formula:
From: | To: |
Aircon HP (Horsepower) calculation determines the appropriate air conditioning capacity needed for a room based on its area in square meters. Proper sizing ensures efficient cooling and energy consumption.
The calculator uses the standard Philippine aircon sizing formula:
Where:
Explanation: This formula is commonly used in the Philippines where 1 HP aircon typically covers approximately 18 square meters of room area.
Details: Correct aircon sizing is crucial for energy efficiency, optimal cooling performance, and preventing premature wear and tear. Undersized units struggle to cool, while oversized units cycle too frequently.
Tips: Enter the room area in square meters. Measure the length and width of your room and multiply them to get the area. The calculator will determine the recommended aircon horsepower.
Q1: Why is 18 sqm used as the divisor?
A: This is a standard conversion factor used in the Philippines where 1 horsepower aircon typically covers 16-20 square meters, with 18 being the average.
Q2: What if my room has high ceilings?
A: For rooms with ceilings higher than 2.7 meters, consider increasing the HP by 0.5 to account for the additional volume.
Q3: Does room orientation affect HP requirements?
A: Yes, rooms with large windows facing west may require additional cooling capacity due to afternoon sun exposure.
Q4: What about rooms with many occupants or heat-generating appliances?
A: For rooms with multiple people, computers, or other heat sources, consider increasing the calculated HP by 0.5 to 1.0.
Q5: Is this calculation accurate for inverter aircons?
A: Yes, the HP requirement remains the same, but inverter units provide better energy efficiency and temperature control.
