Aircon Size Formula:
From: | To: |
Aircon size calculation determines the appropriate cooling capacity (in tons) needed for a room based on its area. Proper sizing ensures efficient cooling, energy savings, and prevents overworking the unit.
The calculator uses the aircon size formula:
Where:
Explanation: The formula calculates the required cooling capacity by multiplying room area by standard BTU requirements and converting to tons.
Details: Correct aircon sizing is crucial for energy efficiency, optimal cooling performance, extended equipment lifespan, and cost savings. Oversized units cycle frequently, while undersized units run continuously.
Tips: Enter room area in square feet. Measure the length and width of the room and multiply to get the area. Ensure accurate measurements for proper sizing.
Q1: Why is 25 BTU per square foot used?
A: This is a standard factor for average rooms with 8-foot ceilings, normal insulation, and moderate sun exposure.
Q2: What if my room has high ceilings?
A: For rooms with ceilings higher than 8 feet, increase the BTU factor proportionally (e.g., 30 BTU/sq ft for 10-foot ceilings).
Q3: How does room orientation affect sizing?
A: South-facing rooms with more sun exposure may require 10-20% more capacity, while north-facing rooms may need less.
Q4: What about rooms with many windows?
A: Add 1000 BTU for each window, especially if they receive direct sunlight.
Q5: Should I round up the calculated size?
A: It's generally recommended to round up to the nearest standard unit size (0.5, 1, 1.5, 2 tons, etc.) for optimal performance.
