When it comes to cooling tower operation, understanding the difference between wet bulb and dry bulb temperatures isn’t just academic—it’s a foundational aspect of optimizing performance and achieving significant energy efficiency.

What Are Wet Bulb and Dry Bulb Temperatures?

• Dry Bulb Temperature is the ambient air temperature measured using a regular thermometer.

• Wet Bulb Temperature is the lowest temperature air can reach through evaporation, accounting for humidity. It plays a critical role in defining the theoretical cooling limit of evaporative systems like cooling towers.

The closer the wet bulb is to the dry bulb, the more humid the air—making evaporation (and cooling) less efficient.

Why It Matters for Cooling Towers

Cooling towers function by allowing water to evaporate, removing heat in the process. The effectiveness of this process directly depends on the wet bulb temperature.

Higher wet bulb temps mean reduced cooling efficiency. This makes it critical to factor in these values when designing or upgrading cooling systems.

AAD Tech’s Smart Approach to Cooling Tower Optimization

At AAD Tech India, we integrate these parameters into every aspect of our cooling tower retrofits. Here’s how:

1. AAD Tech-Ziehl Abegg EC Fan Retrofits

• Designed for maximum energy efficiency.

• Fan speed adjusts automatically based on real-time wet bulb readings.

• Reduces overcooling and undercooling, optimizing energy use.

2. Smart Sensors & IoT-Based Monitoring

• Sensors measure both wet and dry bulb temps to offer dynamic control.

• Connected to our cloud-enabled control systems, they provide real-time diagnostics and allow remote maintenance.

3. Predictive Maintenance & Optimization

• Using data from ambient temperatures and system load, we predict component stress and suggest proactive maintenance.

• Avoid downtime, reduce maintenance costs, and increase system lifespan.

The Payoff: Energy, Cost, and Carbon Savings

• Energy Reduction: Our clients report up to 40% savings in cooling tower energy usage post-retrofit.

• Operational Efficiency: Consistent water temperature management improves HVAC system performance.

• Sustainability Impact: Reducing overuse of electricity helps cut carbon emissions—crucial for reaching Net Zero Goals.
