BTU Calculation Formula:
| From: | To: |
BTU (British Thermal Unit) calculation is used to determine the cooling capacity of split air conditioning systems. It helps in selecting the right size AC unit for a specific space based on its cooling requirements.
The calculator uses the simple formula:
Where:
Explanation: This formula converts cooling capacity from tons to BTU/h, which is the standard measurement for air conditioner capacity.
Details: Proper BTU calculation ensures you select an AC unit with adequate cooling capacity for your space. An undersized unit will struggle to cool, while an oversized unit will cycle too frequently, reducing efficiency and comfort.
Tips: Enter the cooling capacity in tons. The calculator will automatically convert it to BTU/h. For accurate results, consult with an HVAC professional to determine the appropriate tonnage for your space.
Q1: What is the relationship between tons and BTU?
A: 1 ton of cooling capacity equals 12,000 BTU per hour. This measurement originated from the amount of heat needed to melt one ton of ice in 24 hours.
Q2: How do I determine the right tonnage for my room?
A: Room size, insulation, ceiling height, window area, and climate all affect the required tonnage. Generally, 1 ton cools approximately 400-600 square feet, but professional calculation is recommended.
Q3: What happens if I choose the wrong size AC?
A: An undersized AC will run continuously without reaching desired temperature, while an oversized AC will short-cycle, leading to poor humidity control and reduced efficiency.
Q4: Are there other factors besides square footage?
A: Yes, consider insulation quality, number of windows, ceiling height, number of occupants, appliance heat output, and sunlight exposure when sizing an AC unit.
Q5: Can I use this calculator for central AC systems?
A: Yes, the ton to BTU conversion applies to all types of air conditioning systems, including split AC, window AC, and central AC systems.
