Used to cool the greenhouse.

Ventilation air is pumped through filtering cellular panels with a thickness of about 100 mm (in fact, heat exchangers), the humidity of which is maintained at a level of over 90 percent. A wet radiator is either enclosed in a housing together with a fan (evaporative air conditioning), or placed as a filling in openings for supply ventilation.

They allow you to reduce the temperature by 8-10 C.
