Method and system for controlling the climate of an insect rearing climate area
A system controls the air climate in an insect rearing climate housing. The system has an insect rearing climate housing with clusters of one or more stacks of crates with insects. The crates have at least two ventilation openings associated with each crate. An aeration system has an air control unit with a database having a reference table with conditioned air properties in relation to input parameter(s). Aeration devices are connected to the air control unit adjacent to each stack of crates, and have a plurality of exit openings that provide airstreams over the insects. The method retrieves input parameter(s) for the air control unit per cluster of crates, the air control unit determines appropriate conditioned air properties of the airstreams based on the retrieved input parameter(s), and for each individual cluster of crates separately, the air control unit sets the determined conditioned air properties of the airstreams.
