Ventilation, Recirculation
Min Supply Ratio is the lowest share (of Supply given at the Ventilation tab) of air (outdoor + re-circulated) that the ventilation system delivers to the zone.
Min Return Ratio is the minimum share of re-circulated air in the ventilation system.
- Max Return Ratio is the maximum share of re-circulated air in the ventilation system.
- Setp CO2 is the set-point for the CO2-level in the zone, which the ventilation system should try to meet. If Setp CO2 = 0 the system do not control towards a certain CO2-level.
- Setp Humid is the set-point for the moisture content in the indoor air, which the ventilation system should try to meet. If the moisture content of the indoor air is below the set-point, the humidifier starts to bring the humidity up to the desired level. If Setp Humid = 0 the system is not controlled towards a minimum humidity level of the indoor air.
- Setp Dehumid is the set-point for the moisture content in the indoor air, which the ventilation system should try to meet. If the moisture content of the indoor air is above the set-point, the de-humidifier starts to bring the humidity down to the desired level. If Setp Humid = 0 the system is not controlled towards a maximum humidity level of the indoor air.
- Min Inlet Temp is the lowest acceptable temperature of the inlet air to the zone.
- Max Inlet Temp is the highest acceptable temperature of the inlet air to the zone.
- Setp Temp is the desired operative temperature of the zone.
Control of ventilation systems with recirculation of the air happens according to the description given in the theory section.
