1. What is a BTU/hr to HP Air Conditioning Calculator?

Definition: This calculator converts BTU per hour (BTU/h) to horsepower (HP) for air conditioning systems.

Purpose: It helps HVAC professionals and engineers convert between these common units of cooling capacity.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( HP \) — Horsepower
• \( Q \) — BTU per hour (BTU/h)

Explanation: The conversion factor 2545 represents the number of BTU per hour equivalent to 1 horsepower.

3. Importance of BTU to HP Conversion

Details: Understanding this conversion helps in sizing air conditioning systems and comparing different cooling capacities.

4. Using the Calculator

Tips: Simply enter the BTU per hour value to get the equivalent horsepower. The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why 2545 as the conversion factor?
A: 1 horsepower equals 2544.43 BTU/h (rounded to 2545), based on the mechanical equivalent of heat.

Q2: Is this conversion specific to air conditioning?
A: While commonly used for AC, it applies to any heat transfer calculation where you need to convert between BTU/h and HP.

Q3: How accurate is this conversion?
A: The conversion is mathematically precise, though real-world system efficiencies may vary.

Q4: What's a typical BTU/h rating for residential AC?
A: Common residential units range from 12,000 BTU/h (1 ton) to 60,000 BTU/h (5 tons).

Q5: How does this relate to tons of refrigeration?
A: 1 ton of refrigeration = 12,000 BTU/h = approximately 4.716 HP.
