1. What is Cooling Tower Range?

The cooling tower range is the temperature difference between the hot water entering the tower (T_hot) and the cold water leaving the tower (T_cold). It evaluates cooling tower performance as temperature range of water cooled.

2. How Does the Calculator Work?

The calculator uses the cooling tower range formula:

Where:

• \( T_{hot} \) — Inlet water temperature (°C)
• \( T_{cold} \) — Outlet water temperature (°C)
• \( Range \) — Temperature difference (°C)

Explanation: The range indicates how effectively the cooling tower is removing heat from the water. A larger range typically indicates better cooling performance.

3. Importance of Range Calculation

Details: Monitoring cooling tower range is essential for assessing cooling efficiency, optimizing energy consumption, and maintaining proper system operation in HVAC and industrial processes.

4. Using the Calculator

Tips: Enter T_hot (inlet temperature) and T_cold (outlet temperature) in degrees Celsius. T_hot must be greater than T_cold for valid calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical cooling tower range?
A: Typical ranges vary by application but generally fall between 5-15°C for standard cooling tower operations.

Q2: How does range affect cooling tower performance?
A: A larger range indicates more heat removal and better cooling efficiency, while a smaller range may suggest reduced performance or fouling issues.

Q3: What factors can affect cooling tower range?
A: Ambient temperature, humidity, airflow, water flow rate, and tower maintenance all impact the achievable range.

Q4: When should range measurements be taken?
A: Regular monitoring during normal operation conditions, preferably during peak cooling demand periods for accurate performance assessment.

Q5: How is range different from approach?
A: Range is the water temperature difference (T_hot - T_cold), while approach is the difference between cold water temperature and wet-bulb temperature.
