Adiabatic Cooling Systems

During summer months, rainwater is used for air conditioners in the building of the Institute of Physics. For the process of adiabatic cooling, rainwater is sprayed on the building's exhaust air whereby fresh air entering the building is cooled through a heat exchanger. The use of rainwater means to save both drinking water and waste water.

This process of air conditioning of a building is effective in cooling incoming air to a temperature of 21 - 22 °C with outside temperatures of even up to 30 °C, without having to revert to technical cooling systems.
