The rack mounted fiber optic
terminal box can be a sliding, dummy and dustproof design.
Changes in the airflow are achieved through opening and closing the
terminal box damper.
This section presents the improved dynamic control strategy for VAV
terminal box control that enables matching of ventilation rates with actual zone occupancy to minimize energy use for cooling, reheating, and fan operation.
Figure 5 shows the relation of simulated actual minimum airflow and the design value under different ratios of the static pressure set value and the design
terminal box static pressure value, [omega] = [P.sub.[s,des]]/[P.sub.[box,des]].
Motor options are varied and include brakes, thermal overload protection, space heaters, potted
terminal boxes, condensation drain holes and connectivity solutions.
The 1LE motor range has user friendly
terminal boxes and a rugged design.
"The 1LE motor range features user-friendly
terminal boxes and a ruggedized design, and has been created with leading-edge modelling techniques to produce new internal geometries," said Nadeem Kazmi, Head of Industry, Siemens Pakistan.
