1. What is Cooling Tower Cooling Capacity?

Definition: This calculator estimates the cooling capacity of a cooling tower based on water mass flow rate, temperature difference, and latent heat if applicable.

Purpose: It helps HVAC professionals and engineers determine the cooling capacity required for industrial or commercial cooling systems.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Total cooling capacity (BTU)
• \( m \) — Water mass flow rate (lb)
• \( c \) — Specific heat capacity of water (BTU/lb·°F)
• \( \Delta T \) — Temperature difference (°F)
• \( Q_{latent} \) — Latent heat from evaporation (BTU)

Explanation: The sensible heat is calculated from mass flow and temperature difference, then latent heat is added if applicable.

3. Importance of Cooling Capacity Calculation

Details: Proper cooling capacity estimation ensures efficient system design, energy savings, and adequate cooling for processes.

4. Using the Calculator

Tips: Enter water mass flow rate in lb, specific heat (default 1.0 BTU/lb·°F for water), temperature difference in °F, and latent heat if applicable (default 0). All values must be ≥ 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical specific heat for water?
A: Water has a specific heat of about 1.0 BTU/lb·°F, but this can vary slightly with temperature and impurities.

Q2: When should I include latent heat?
A: Include latent heat when evaporation is significant in your cooling process (common in cooling towers).

Q3: How do I find the mass flow rate?
A: Measure flow rate in gallons per minute (GPM) and multiply by 8.34 lb/gal (for water).

Q4: What's a typical temperature difference?
A: Cooling towers typically have ΔT of 10-30°F depending on design and application.

Q5: How do I convert BTU to tons of refrigeration?
A: Divide BTU by 12,000 to get cooling tons (1 ton = 12,000 BTU/hr).
