The air temperature in the rooms will be maintained for the summer season. For the air conditioning of the premises of the building - where necessary - a climate split and multi-split systems operating on direct evaporation are installed. The indoor units are for high-wall installation. Condensate is drained on PVC pipes with thermal insulation and is connected to vertical sewerage branches through S-shaped siphon to prevent the spread of odors. Each body has a separate remote control which provides the possibility of individual adjustment of the operating mode. Each body operates at full recirculation, thus providing only the room temperature regime.
