1. What is a kW to Ton Calculator?

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

Purpose: It helps HVAC professionals and engineers convert between power units when designing or evaluating cooling systems.

2. How Does the Calculator Work?

The calculator uses the formula:

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

Where:

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

Explanation: One ton of refrigeration equals 3.517 kW of cooling power. This conversion is based on the amount of heat needed to melt one ton of ice in 24 hours.

3. Importance of kW to Ton Conversion

Details: Proper conversion ensures accurate system sizing, energy efficiency calculations, and equipment selection in refrigeration and air conditioning applications.

4. Using the Calculator

Tips: Simply enter the power in kilowatts (must be > 0) and the calculator will provide the equivalent in tons of refrigeration.

5. Frequently Asked Questions (FAQ)

Q1: What is a ton of refrigeration?
A: It's a unit of power equal to the cooling effect of melting one ton of ice in 24 hours (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 definition of one ton (2000 lb) over 24 hours.

Q3: When would I need this conversion?
A: When comparing cooling systems, reading equipment specifications, or converting between metric and imperial units.

Q4: Is this the same for all refrigerants?
A: The ton-to-kW ratio is constant, but actual system performance depends on refrigerant properties and system design.

Q5: How precise is this conversion?
A: The 3.517 factor is standard, but practical systems may vary slightly due to efficiency factors and operating conditions.
