1. What Is AC Unit Sizing In India?

In India, air conditioner capacity is commonly measured in tons of refrigeration, where 1 ton equals 12,000 BTU/h. This measurement helps determine the appropriate AC size for different room sizes and cooling requirements.

2. How Does The Calculator Work?

The calculator uses the standard conversion formula:

Where:

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

Explanation: This formula converts BTU rating to the equivalent tons of cooling capacity, which is the standard measurement used for AC units in India.

3. Importance Of Proper AC Sizing

Details: Proper AC sizing is crucial for energy efficiency, optimal cooling performance, and preventing excessive wear on the unit. An undersized AC will struggle to cool the space, while an oversized unit will cycle too frequently.

4. Using The Calculator

Tips: Enter the BTU rating of your air conditioner to calculate the equivalent tonnage. This helps in comparing different AC models and selecting the right capacity for your space.

5. Frequently Asked Questions (FAQ)

Q1: Why is AC capacity measured in tons in India?
A: The "ton" measurement originated from the amount of heat required to melt one ton of ice in 24 hours, which equals 12,000 BTU/h. This traditional measurement remains widely used in India's AC industry.

Q2: What's the relationship between room size and AC tonnage?
A: Generally, 1 ton of cooling capacity is suitable for rooms up to 100-150 square feet, but this varies based on factors like insulation, ceiling height, window area, and local climate.

Q3: Are there different types of tons in refrigeration?
A: While the standard ton is 12,000 BTU/h, some regions may use slightly different values, but the Indian market consistently uses the 12,000 BTU/h standard.

Q4: How accurate is this conversion?
A: The conversion is mathematically exact - 1 ton always equals 12,000 BTU/h. However, actual cooling performance depends on the AC's efficiency rating and installation factors.

Q5: Should I consider other factors besides tonnage when buying an AC?
A: Yes, also consider energy efficiency (BEE star rating), inverter technology, brand reputation, after-sales service, and additional features like air purification or smart controls.
