Indirect Evaporative Cooler Performance Study

Approx. component budget: Rs. 7,000 - 12,000

Objective

Measure the cooling and the effectiveness of an indirect evaporative cooler at different airflow rates.

What you will build

Dry and wet air channels, a cooling pad with a small water pump, a fan and temperature/humidity sensors.

Results you can expect

• Temperature drop
• Effectiveness vs airflow
• Comparison with a direct cooler

What you will learn

Psychrometrics and HVAC basics, with low-energy cooling that suits Indian summers.

Tools and notes

Sensors, anemometer, Excel. Results depend on weather, so test on several days.

Resume points from this project

• Built and tested Indirect Evaporative Cooler Performance Study; objective: measure how much an indirect evaporative cooler cools air and how effective it is at different airflow rates.
• Measured and analysed temperature drop achieved and Effectiveness vs airflow; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
