Trickle bodies for the air conditioning of, in particular, animal housings, that possess only partially latticed layer elements. Trickle bodies are formed of a plurality of sandwiched layer elements that, in known trickle bodies, are formed of corrugated and completely latticed plastics foil. The trickle bodies formed of such layer elements possess a relatively low stability and a limited evaporation capacity. The plastics-formed layer elements of the instant invention are produced by injection molding, allowing layer elements having corrugation heights of more than 12 mm to be formed. Such trickle bodies are more stable, enable a high evaporation capacity and are, moreover, also less permeable to light.
