Cooling Capacity Formula:
From: | To: |
Definition: This calculator converts cooling capacity from BTU/h (British Thermal Units per hour) to tons of refrigeration.
Purpose: It helps HVAC professionals and engineers convert between these common units of cooling capacity measurement.
The calculator uses the formula:
Where:
Explanation: One ton of refrigeration equals 12,000 BTU/h, so we divide the BTU value by 12,000 to get equivalent tons.
Details: Understanding both units is essential for proper HVAC system sizing, specification, and comparison of cooling equipment.
Tips: Simply enter the BTU/h value (must be > 0) and the calculator will instantly show the equivalent tons of cooling.
Q1: Why is 12,000 BTU/h equal to 1 ton?
A: This comes from the amount of heat needed to melt one ton (2000 lbs) of ice in 24 hours (288,000 BTU/24h = 12,000 BTU/h).
Q2: What's a typical residential AC capacity?
A: Most homes have 1.5 to 5 ton systems (18,000 to 60,000 BTU/h).
Q3: How do I find my system's BTU rating?
A: Check the equipment nameplate or specifications. For existing systems, look for model numbers that often include capacity.
Q4: What's the difference between BTU and BTU/h?
A: BTU measures energy, while BTU/h measures power (energy per time). In HVAC, we typically use BTU/h.
Q5: Can I convert tons back to BTU/h?
A: Yes, simply multiply tons by 12,000 (e.g., 2 tons = 24,000 BTU/h).
