Systems for cooling of the building.
According to the local climate, natural ventilation is possible to run only short time period. All the rest of the year rooms have to have air conditioning.
Preconditioned outside air supply for each room 1-3 air changes per hour, to keep comfortable indoor environment. Air treatment in the air handling unit – filtering, dehumidifying and cooling.
Slight excess of dry make-up air ensures that treated air rather than outdoor air will fill the building cavities, keeping them safe from condensation, molds and mildew. Dehumidification will be controlled by dew point temperature, to prevent the condensation in the building envelope.
To lower room temperature, concrete slab will be cooled till 20C with built in chilled water pipes. That will give good thermal stability and lover peak cooling loads.
Water-cooled chiller with heat rejection via heat exchangers to the swimming pool, hot water preheating and outside air. For noise reduction to the surroundings, chiller is placed in technical room.
Employee and guest spaces will be air conditioned by multi split units and mechanical air handling units for basic air exchange.
