Problem Problem Specification -Develop a method to monitor the real time efficiency of a set of cooling towers -Provide recommendations to improve the overall efficiency of the set using the real time analysis. Design Constraints Non-intrusive – No changes to the structure – No interference Durable – weather conditions – resist damage bearing multiple take-downs Portable – The system fits in 1 or 2 suitcases – 4 to 8 hour set up

Cooling Tower Basics Passes water and air over “fill” surface area Cools through evaporation Cools fluid to near wet bulb temperature Why use cooling towers? Human comfort Industrial process Power generation Resources Water Electricity Chemical

Our Approach

Instrumentation and Measurements Required Measurement required Ambient Air Temperatures  Dry bulb  Wet bulb Cold Water Flow Water temperatures  Hot Water  Cold Water Fan Power Ambient Relative humidity at inlet (weather station) and RH at exhaust Atmospheric pressure Monitoring System 100Ω Platinum RTD Magnetic Mount RTD Current Transducer Wireless DAQ System Weather Station Ultrasonic Flow- meter

LabVIEW Monitors and displays real time data Analyzes stored data Displays aggregate data for trend identification Modular programing with sub-VI’s for ease of modification
