1. What is the Split AC Size Formula?

The Split AC Size Formula calculates the required air conditioning capacity in tons of refrigeration based on BTU (British Thermal Units) per hour. This helps determine the appropriate size for split AC systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Ton \) — Tons of refrigeration (cooling capacity)
• \( BTU \) — British Thermal Units per hour (BTU/h)

Explanation: One ton of refrigeration equals 12,000 BTU per hour. This conversion helps determine the appropriate AC unit size for a given space.

3. Importance of AC Sizing

Details: Proper AC sizing is crucial for energy efficiency, comfort, and system longevity. Undersized units struggle to cool, while oversized units short-cycle, reducing efficiency and humidity control.

4. Using the Calculator

Tips: Enter BTU value in BTU/h. The value must be valid (BTU > 0). The calculator will compute the equivalent tons of refrigeration.

5. Frequently Asked Questions (FAQ)

Q1: Why is proper AC sizing important?
A: Proper sizing ensures optimal performance, energy efficiency, and comfort while preventing premature system wear.

Q2: What factors affect BTU requirements?
A: Room size, insulation, windows, climate, number of occupants, and heat-generating appliances all affect BTU needs.

Q3: How many square feet does 1 ton cool?
A: Generally, 1 ton cools 400-600 square feet, but this varies based on factors like insulation and climate.

Q4: What's the difference between BTU and tons?
A: BTU measures heat removal capacity per hour, while tons represent cooling capacity (1 ton = 12,000 BTU/h).

Q5: Should I round up when sizing AC units?
A: It's generally recommended to round up to the nearest half-ton for better performance and efficiency.
