Cooling Aerocool

by Abbi-Aerotech B.V.

When a tunnel ventilation system is in place, it is relatively easy to add a cooling system. For this purpose so-called pads are used. Water is pumped across these pads and fans draw air through them. The resulting airflow makes the water evaporate and cools down the hot air. This cooler air is then drawn through the building. Depending on outside ...
