Cooling Capacity Calculator — Size Your AC System Correctly

Cooling Capacity Calculator

Calculate the right air conditioner size for your room. Understand how room dimensions, insulation, and climate affect cooling requirements.

Step 1: Room Details

Understanding Cooling Capacity

Proper AC sizing ensures efficient cooling. Undersized units won’t cool your room effectively, while oversized ones waste energy and may not dehumidify properly. The calculation considers room volume, insulation, and desired temperature.

About Insulation Factors

Insulation level affects how much cooling is needed. Well-insulated rooms (0.8-1.0) require less cooling power, while poorly insulated spaces (1.2-1.5) need more. Modern homes typically have values around 1.0.

Cooling Requirement Analysis

Cooling Capacity Formula

BTU/h = Volume × ΔT × Insulation Factor × 0.133 + (Occupants × 400)

The cooling capacity is calculated using a standard formula that considers room volume, temperature difference, insulation quality, and number of occupants. Actual requirements may vary based on window quality, external walls, and specific room characteristics.
