1. What is kW per Ton?

kW per ton is a measure of energy efficiency in refrigeration and air conditioning systems. It represents the amount of electrical power (in kilowatts) required to produce one ton of cooling capacity.

2. How Does the Calculator Work?

The calculator uses the kW per ton formula:

Where:

• \( P \) — Power consumption (kilowatts)
• \( C \) — Cooling capacity (tons)

Explanation: This ratio indicates the energy efficiency of cooling equipment. Lower values represent more efficient systems.

3. Importance of kW/Ton Calculation

Details: kW per ton is a critical metric for evaluating HVAC system efficiency, comparing equipment performance, and estimating operating costs in commercial and industrial cooling applications.

4. Using the Calculator

Tips: Enter power consumption in kilowatts and cooling capacity in tons. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a good kW/ton value?
A: Modern efficient systems typically range from 0.5 to 0.8 kW/ton. Values below 0.6 kW/ton are considered excellent efficiency.

Q2: How does kW/ton relate to COP?
A: Coefficient of Performance (COP) is the inverse of kW/ton divided by 3.516. COP = 3.516 / (kW/ton).

Q3: Why is kW/ton important for energy efficiency?
A: It directly measures how much electricity is needed for cooling, helping identify opportunities for energy savings and system optimization.

Q4: What factors affect kW/ton values?
A: System design, compressor efficiency, heat exchanger performance, operating conditions, and maintenance practices all influence kW/ton.

Q5: Can kW/ton be used for all cooling systems?
A: Yes, it's applicable to chillers, air conditioners, refrigeration systems, and any equipment where cooling capacity is measured in tons.
