Aircon Horsepower Formula:
From: | To: |
Definition: This calculator estimates the required air conditioning horsepower based on room area and the unit's coefficient of performance.
Purpose: It helps determine the appropriate air conditioner size for a given space to ensure efficient cooling.
The calculator uses the formula:
Where:
Explanation: The formula converts room area into cooling requirements, adjusted by the unit's efficiency.
Details: Correct sizing ensures energy efficiency, proper cooling, and prevents excessive wear on the unit.
Tips: Enter the room area in square meters and the COP (default 3.5). All values must be > 0.
Q1: What is COP?
A: Coefficient of Performance measures aircon efficiency (higher values = more efficient). Modern units typically have COP between 3.0-4.0.
Q2: How do I measure room area?
A: Multiply length by width of the room in meters. Include all connected spaces that aren't separated by doors.
Q3: When would I change the COP value?
A: Check your aircon unit's specifications. Older units may have lower COP (2.5-3.0), while premium models may exceed 4.0.
Q4: What if my room has special conditions?
A: For rooms with high heat loads (south-facing, many windows, etc.), consider adding 10-20% to the calculated HP.
Q5: How does this relate to BTU ratings?
A: 1 HP ≈ 9000 BTU. Multiply the result by 9000 to get approximate BTU requirements.
