What does a ton (refrigeration) represent?

It represents the cooling power to melt one short ton of ice in 24 hours, equivalent to 12,000 BTU/h or around 3516.85 watts.

Why use kilojoule per hour units?

Kilojoule per hour measures energy transfer rates over an hourly period and is suitable for small-to-moderate power levels.

Is this conversion relevant outside HVAC?

While primarily for HVAC and refrigeration, it also applies in building physics, energy auditing, and laboratory calorimetry.

Key Features

Converts cooling power from ton (refrigeration) to kilojoule/hour accurately.
Supports HVAC, refrigeration, and building engineering applications.
Browser-based and easy to use with straightforward input and output.

Examples

2 tons (refrigeration) converts to approximately 25321.34 kJ/h.
0.5 ton (refrigeration) converts to about 6330.34 kJ/h.

Common Use Cases

Rating residential and commercial air-conditioning units using tons and translating to energy rates.
Specifying cooling capacity for commercial refrigeration and cold storage.
Performing HVAC load calculations and building energy audits requiring hourly energy rates.
Laboratory measurements involving calorimetry and low-rate heat transfer over hours.

Tips & Best Practices

Confirm the units involved before converting to maintain consistency.
Apply conversions mainly in HVAC or refrigeration contexts where the ton unit is standard.
Be mindful of unit scale differences when interpreting results in large-tonnage scenarios.

Limitations

Ton (refrigeration) is a non-SI unit mostly used in North America and HVAC industries.
Kilojoule/hour is less common for large power rates and may cause interpretation challenges.
Conversion precision could be affected by rounding when dealing with very large values.
