1. What is a Split AC Tonnage Calculator?

Definition: This calculator converts the cooling capacity of split AC units from BTU/hr to tons, which is the standard measurement used in India's AC industry.

Purpose: Helps consumers and technicians properly size air conditioning units for rooms based on cooling requirements.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T \) — AC tonnage (tons)
• \( BTU \) — British Thermal Units per hour (cooling capacity)

Explanation: 1 ton of refrigeration equals 12,000 BTU/hr. Dividing the BTU rating by 12,000 converts it to tons.

3. Importance of Proper AC Tonnage

Details: Correct tonnage ensures energy efficiency, proper cooling, and prevents overworking the AC unit. Undersized units won't cool effectively, while oversized units short-cycle.

4. Using the Calculator

Tips: Enter the AC unit's BTU rating (typically 5,000-24,000 BTU/hr for residential units). The result shows the equivalent tonnage (0.5-2 tons for most homes).

5. Frequently Asked Questions (FAQ)

Q1: Why is tonnage important for AC units?
A: Tonnage determines the cooling capacity needed for your room size. 1 ton typically covers 100-150 sq ft in Indian conditions.

Q2: How do I find my AC's BTU rating?
A: Check the manufacturer's specifications on the unit or product documentation.

Q3: What's the difference between 1 ton and 1.5 ton AC?
A: 1 ton = 12,000 BTU/hr, 1.5 ton = 18,000 BTU/hr. The 1.5 ton unit can cool larger spaces (150-250 sq ft).

Q4: Does this calculator work for all AC types?
A: Primarily for split ACs, but the formula applies to window ACs and other types as well.

Q5: How does room size affect tonnage requirements?
A: Larger rooms need higher tonnage. Other factors include ceiling height, insulation, windows, and heat-generating appliances.
