Features of the equipment room and ventilation modes of devices
1. The in-row air conditioner is placed between two cabinets. The directions of air supply and return
in the in-row air conditioner are opposite to that on the equipment cabinet. The ventilation mode of
equipment cabinet must be "air inlet from front - air outlet from rear".
2. For an in-row air conditioner, the width ranges from 0.3 m to 0.6 m and the depth ranges
from 1.0 m to 1.2 m.
3. The in-row air conditioners are close to heat sources (cabinets), and the returned air temperature
is high. Therefore, the cooling efficiency of in-row air conditioners is high.
4. In-row air conditioners are commonly used in the modular data center. Some communication
equipment rooms also use in-row air conditioners for local cooling supplement, so as to eliminate
partial hot spots.
