Problems with Cold Aisle containment

1.There are disadvantages in its own principle

Due to the principle of hot and cold aisles, the entire air supply area needs to be sealed (cold aisle sealing). Although the loss of air volume and cooling capacity is greatly reduced or avoided, the efficiency of refrigeration is ultimately greatly improved. For this hot and cold aisle closure The primary problem that has always hindered the large-scale promotion of this solution is fire protection. Since all IT equipment is running in the data center, gas fire extinguishing is usually used for fire protection. Since the cold aisle is closed, once the equipment in the cold aisle catches fire, the fire-fighting gas cannot reach the enclosed area within the specified time, which will inevitably cause greater losses.

2.Too much reliance on precision air conditioning

Because the hot and cold aisles mainly rely on precision air conditioners to adjust the temperature, the air flow circulation in the hot and cold aisles needs to be adjusted by precision air conditioners. Moreover, when building hot and cold aisles, the air supply area is required to be closed, making it difficult for managers to detect precision. Air conditioner failure can lead to many problems.
