1. What is Cooling Tower Cooling Capacity?

Cooling tower cooling capacity refers to the amount of heat a cooling tower can remove from water, measured in tons of refrigeration. It determines the tower's ability to cool water for industrial processes, HVAC systems, and power generation applications.

2. How Does the Calculator Work?

The calculator uses the cooling capacity formula:

\[ Capacity = Flow Rate \times Range \times 500 / 12,000 \]

Where:

\( Flow Rate \) — Water flow rate in gallons per minute (GPM)
\( Range \) — Temperature difference between inlet and outlet water in °F
\( 500 \) — Constant (500 BTU/min per ton)
\( 12,000 \) — Constant (BTU per hour per ton)

Explanation: The formula calculates the heat removal capacity based on water flow rate and temperature difference, converting the result to tons of refrigeration.

3. Importance of Cooling Capacity Calculation

Details: Accurate cooling capacity calculation is essential for proper cooling tower selection, system design, energy efficiency optimization, and ensuring adequate cooling for industrial processes and building HVAC systems.

4. Using the Calculator

Tips: Enter flow rate in GPM and temperature range in °F. Both values must be positive numbers. The calculator will provide the cooling capacity in tons of refrigeration.

5. Frequently Asked Questions (FAQ)

Q1: What is a ton of refrigeration?
A: One ton of refrigeration equals 12,000 BTU per hour, which is the amount of heat required to melt one ton of ice in 24 hours.

Q2: How does flow rate affect cooling capacity?
A: Higher flow rates generally increase cooling capacity, but excessive flow can reduce heat transfer efficiency and increase pumping costs.

Q3: What is the typical range for cooling towers?
A: Typical ranges are 10-30°F for standard applications, but this can vary based on specific system requirements and environmental conditions.

Q4: Are there limitations to this calculation?
A: This calculation provides theoretical capacity. Actual performance depends on factors like wet-bulb temperature, tower design, fill media, and air flow.

Q5: How does ambient temperature affect cooling capacity?
A: Higher ambient wet-bulb temperatures reduce the cooling tower's capacity because they decrease the temperature difference driving the heat transfer process.
