Pad & Fan system

The Pad & Fan system, or mattress cooling, is one of the best-known forms of evaporation cooling, and it is widely used to cool greenhouses especially in southern countries, where the outdoor humidity is often low.

Method of this system;

  1. The dry exterior air is humidified by means of a pad wall.

  2. The humidified air absorbs part of the heat in the greenhouse.

  3. The saturated hot air is extracted from the greenhouse with fans.
