GC10 Room group controller
Functional description ● Performance features Functional description
The GC10 room group controller automatically and decentrally balances the setpoints for laboratory room control (room supply and exhaust air). The room air change rate requirements of DIN 1946, Part 7 are taken into account and are freely programmable. Negative room pressure (in laboratories) or positive room pressure (in clean rooms) may be adjusted by a percentage relative to the room exhaust air or with a fixed offset (. 300 m3/h). The negative room pressure is determined using the following formula: Room supply air= exhaust air * 0,9 Room supply air= exhaust air - 300 Negative room pressure = 10% Offset = 300 m3/h By means of the LON control, the GC10 room group controller fulfills the function of a DDC sub-station. Summated balances (room supply/exhaust air) are available in the BMS as work variable types (SNVT).
And the positive room pressure is calculated with the following formula: Room supply air= exhaust air * 1,1 Room supply air= exhaust air + 300 Positive room pressure = 10% Offset= 300 m3/h
Building Management System
The building management system (BMS) can be integrated anywhere in the work. Malfunction notification, room by room daytime/night-time switching as well as room exhaust and supply air actual values are available via SNVTs.
Where there is sufficient air intake and circulation (. around doors), the room supply/exhaust air ratio should be established using a calculated percentage rather than a fixed offset. The percentage ratio should be approx. 10...15% in order pensate possible uracies of approx. 10% in the entire system (. excessively low upstream and downstream flow routes). In airtight rooms, . where there is insufficient air intake and circulation, a fixed offset must be added (positive room pressure) or subtracted (negative room pressure.
