FAQ

Frequently asked questions about refrigeration calculation

What is the difference between a refrigeration tonne and a kilowatt?
One refrigeration tonne (RT) equals 3.517 kW. RT is used in Gulf and American markets while kW is the standard in European specifications. The Elfarida Ice calculator displays both units automatically.
Is the result sufficient for actual construction?
The result is an initial estimate for planning and budgeting. Actual construction requires a detailed thermal study covering insulation type, evaporator location, and compressor efficiency. The Elfarida Ice team provides the full study at no cost.
What does the safety factor in the calculation mean?
We add 15–25% above the calculated thermal load to compensate for gradual equipment ageing and unexpected loads, ensuring long-term thermal stability.
How does outdoor temperature affect the required capacity?
Each additional degree Celsius outside raises the wall thermal load by approximately 2–4%. Saudi summers can reach 50 °C, requiring design safety factors higher than European standards.
