1. What is kW per Tonne?

Definition: kW per Tonne (kW/T) is a measure of power required per ton of cooling capacity in refrigeration systems.

Purpose: It helps HVAC professionals and engineers determine the power requirements for cooling systems.

2. How Does the Calculator Work?

The calculator uses the constant:

Where:

• \( kW/T \) — Kilowatts per ton of cooling (3.517 kW/ton)
• This is multiplied by the cooling capacity in tons

Explanation: The standard conversion factor of 3.517 kW per ton is used to calculate the total power requirement.

3. Importance of kW per Tonne Calculation

Details: Proper power calculation ensures correct system sizing, energy efficiency, and prevents overloading electrical systems.

4. Using the Calculator

Tips: Simply enter the cooling capacity in tons. The calculator will multiply it by 3.517 kW/ton to give the total power requirement.

5. Frequently Asked Questions (FAQ)

Q1: Why is 3.517 kW equal to 1 ton of cooling?
A: This comes from the conversion of 12,000 BTU/hr (1 ton of cooling) to kilowatts (3.517 kW).

Q2: Does this value change for different systems?
A: 3.517 is the theoretical value. Actual systems may vary slightly due to efficiency factors.

Q3: How do I convert back from kW to tons?
A: Divide the kW value by 3.517 to get tons of cooling capacity.

Q4: Is this the same as EER or COP?
A: No, EER and COP are efficiency metrics, while kW/T is a power-to-capacity ratio.

Q5: What if my system has a different kW/ton rating?
A: For more precise calculations, use the actual kW/ton value specified for your equipment.
