Conversion Formula:
From: | To: |
The conversion from horsepower (HP) to tons of refrigeration is used in the HVAC and refrigeration industry to relate mechanical power to cooling capacity. One ton of refrigeration is equivalent to the cooling effect of melting one ton of ice in 24 hours.
The calculator uses the conversion formula:
Where:
Explanation: This conversion factor (4.71) represents the relationship between mechanical power input and cooling capacity output in refrigeration systems.
Details: This conversion is essential for HVAC engineers, refrigeration technicians, and mechanical designers to properly size equipment, select appropriate compressors, and ensure system efficiency in cooling applications.
Tips: Enter the horsepower value in the input field. The value must be greater than zero. The calculator will automatically compute the equivalent tons of refrigeration.
Q1: Why is the conversion factor 4.71?
A: The factor 4.71 comes from the relationship between mechanical power (1 HP = 2545 BTU/hr) and cooling capacity (1 ton = 12,000 BTU/hr), resulting in 2545/12000 ≈ 0.212, and its reciprocal 1/0.212 ≈ 4.71.
Q2: Is this conversion exact for all systems?
A: This is a general conversion. Actual system efficiency may vary based on compressor type, refrigerant, and operating conditions.
Q3: What are typical HP to ton ratios in real systems?
A: Modern efficient systems may have better ratios (less HP per ton), while older systems may require more HP per ton of cooling.
Q4: Can this calculator be used for air conditioning systems?
A: Yes, this conversion applies to both refrigeration and air conditioning systems that use mechanical compression.
Q5: How accurate is this conversion?
A: This provides a good estimate for system sizing, but professional engineering analysis should be conducted for precise equipment selection.
