1. What is BTU to HP Conversion?

The conversion from British Thermal Units per hour (BTU/hr) to horsepower (HP) for air conditioning systems helps understand the mechanical power equivalent of cooling capacity.

2. How Does the Calculator Work?

The calculator uses the following conversion:

\[ HP = \frac{BTU_{hr}}{12000} \times 4.7162 \]

Where:

\( BTU_{hr} \) — British Thermal Units per hour
12000 BTU/hr = 1 ton of refrigeration
1 ton of refrigeration = 4.7162 HP

Explanation: First converts BTU/hr to tons of cooling, then converts tons to horsepower.

3. Importance of AC Power Conversion

Details: Understanding the relationship between cooling capacity (BTU) and mechanical power (HP) is essential for system sizing, energy efficiency analysis, and equipment selection.

4. Using the Calculator

Tips: Enter the BTU/hr rating of your AC unit. The value must be greater than zero. The calculator will provide the equivalent horsepower.

5. Frequently Asked Questions (FAQ)

Q1: Why 12,000 BTU/hr per ton?
A: This is the standard definition - 1 ton of refrigeration equals the cooling effect of melting 1 ton of ice in 24 hours (12,000 BTU/hr).

Q2: How accurate is this conversion?
A: This provides a theoretical conversion. Actual system performance depends on efficiency (SEER/EER ratings).

Q3: What's the difference between HP and BTU?
A: HP measures mechanical power, BTU measures thermal energy. This conversion shows the mechanical power needed to produce equivalent cooling.

Q4: Can I use this for heat pumps?
A: Yes, the conversion applies to any system rated in BTU/hr, but remember heating and cooling capacities may differ.

Q5: What about compressor HP vs system BTU?
A: This calculates theoretical equivalent HP. Actual compressor HP will be less due to system efficiency.
