Depending on the geographic location and/or cultivated crop, it may be necessary to cool the greenhouse.
Adiabatic cooling (Pad & Fan) only has a slight effect, but may be enough for crops that are grown in a warm climate.
Roof sparkling is used as an alternative form of cooling, whereby the temperature in the greenhouse can be reduced about 2° C.
Forced cooling, last but not least, takes place through compressors and is applied with a strict production planning, whereby, for example, the bud development of the crop is manipulated.
A combination of air heating/ air cooling is possible if no pipe rail system is required. With convectors a compound system is developed, through which heating and cooling are controlled from one unit.
This system can be cooled and heated about 60% faster than with pipe heating. The CO2 quantity is also integrated in this.
