BK117: Temperature sensors
The fifteen temperature sensors are placed as follows:
- BK117 is divided into two halves, DOOR and REAR
- Five sensors are placed near the supply fans of the CRACs
- Two sensors are placed under the cold aisle VENTS
- Two sensors are placed just below the cold aisle ROOF
- Two sensors are placed at the EXHAUSTs, near the far wall as seen from
the CRACs
- Two sensors are placed over the EXHAUSTs, near the hot aisle ROOF
- So the air flows from Supply*CRAC to Supply*Vent to Supply*Roof to Return*Low to Return*High to Return*CRAC
Simple!
