1. What is a kW to Ton Converter?

Definition: This calculator converts power in kilowatts (kW) to tons of refrigeration, a common unit in cooling systems.

Purpose: It helps HVAC professionals and engineers convert between power units when working with refrigeration and air conditioning systems.

2. How Does the Converter Work?

The converter uses the formula:

\[ Tons = \frac{P_{kW}}{3.517} \]

Where:

\( Tons \) — Tons of refrigeration
\( P_{kW} \) — Power in kilowatts (kW)

Explanation: 1 ton of refrigeration equals 3.517 kW of cooling power. This conversion factor comes from the definition of a ton of refrigeration.

3. Importance of Power Unit Conversion

Details: Proper unit conversion ensures accurate system sizing, energy efficiency calculations, and equipment specification in HVAC applications.

4. Using the Converter

Tips: Simply enter the power value in kilowatts (kW). The value must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a ton of refrigeration?
A: It's the cooling capacity equivalent to melting 1 ton (2000 lbs) of ice in 24 hours, equal to 12,000 BTU/hr or 3.517 kW.

Q2: Why 3.517 kW per ton?
A: This comes from the heat of fusion of ice (144 BTU/lb) and the time period (24 hours), converted to metric units.

Q3: When would I need this conversion?
A: When working with HVAC equipment specifications, energy calculations, or comparing systems that use different units.

Q4: Is this for electrical or cooling tons?
A: This converts electrical kW input to cooling tons output, assuming standard efficiency.

Q5: Can I convert tons back to kW?
A: Yes, multiply tons by 3.517 to get kW.
