Water Cooling Tower

Technical Description

Cooling towers are a special type of counterflow heat exchanger. Warm water is sprayed from the top down through the column while airflows up through the column. Cooling is predominantly due to the evaporation of the water. The amount of water evaporated is measured. A fan supplies a variable cooling airflow. All important process parameters including the water flow rate are measured electronically and displayed. The measured values can be transferred to a PC for analysis and further processing. A data acquisition card and software are included. Four further cooling columns are available as accessories.

Learning Objectives / Experiments

- Familiarisation with a cooling tower and its
principal parts
- Measurement of the airflow rate, air and water
temperatures and atmospheric humidity
- Changes of the state of air on an h-ω diagram
- Determination of the cooling capacity
- Calculating the process parameters

Features

* Clear experimental set-up on a table₁
* Processing of the measured values on a PC₁
* Transparent, easily exchangeable cooling columns₁
* Complete experiment instructions
