1. What is HVAC Tonnage Calculation?

HVAC tonnage calculation determines the cooling capacity needed for a space. One ton of cooling equals 12,000 BTU/h, and proper sizing is crucial for efficient HVAC system performance.

2. How Does the Calculator Work?

The calculator uses the HVAC tonnage formula:

Where:

• \( Ton \) — Cooling capacity in tons
• \( BTU \) — British Thermal Units per hour

Explanation: This simple conversion calculates the required HVAC tonnage based on the BTU cooling capacity needed for a space.

3. Importance of HVAC Tonnage Calculation

Details: Proper HVAC sizing ensures energy efficiency, optimal comfort, and prevents system overwork. Undersized systems struggle to cool, while oversized systems short cycle and waste energy.

4. Using the Calculator

Tips: Enter the total BTU cooling capacity required for your space. The calculator will convert it to the equivalent tonnage needed for your HVAC system.

5. Frequently Asked Questions (FAQ)

Q1: How many square feet does one ton cool?
A: Generally, one ton cools 400-600 square feet, but this varies based on climate, insulation, and other factors.

Q2: What's the difference between BTU and tonnage?
A: BTU measures cooling capacity, while tonnage is a unit derived from BTU (1 ton = 12,000 BTU/h).

Q3: How do I calculate BTU requirements for my space?
A: BTU calculation considers square footage, ceiling height, insulation, windows, climate, and other factors. Professional load calculations are recommended.

Q4: Can I use this for heat pump sizing?
A: Yes, the same tonnage calculation applies to both air conditioning and heat pump systems.

Q5: What happens if I choose the wrong tonnage?
A: Incorrect sizing leads to poor efficiency, uncomfortable temperatures, higher energy bills, and reduced equipment lifespan.
