What Is A Cold Aisle Cabinet?
Dec 05, 2018

The cold aisle cabinet is controlled by the airflow in the equipment room to save cooling energy and improve server operation reliability. The data center consumes a lot of power. In order to save energy and protect the environment, the data center standard recommends that the data center be arranged by means of hot and cold channels. In order to ensure the efficiency of use of cold air, the cold air passage is closed to form a cold pool. Sliding doors are installed on both sides of the cold pool to facilitate personnel access. The top is transparent, which facilitates the light inside the machine room to enter the cold pool. The top is usually movable and linked to the fire protection system. Once a fire alarm occurs, the top window will automatically fall off to dissipate heat and smoke the cold aisle system, and also facilitate gas fire in the equipment room.

       

Functional expansion of the cold aisle cabinet The interior of the cold aisle system can be extended with sensors such as temperature, humidity, smoke, and infrared to monitor the environmental conditions inside the cold aisle system in real time. In addition, in order to ensure the safety of the cold aisle system, the sliding doors on both sides can also be combined with fingerprint locks, password locks, etc. according to user requirements.

Hot aisle cold aisle concept

The hot aisle/cold aisle is the layout design of the server rack and other computing devices in the data center. The hot aisle cold aisle configuration is designed to save energy and reduce cooling costs by managing airflow.


The simplest data center hot aisle cold aisle design is to align the server racks in a row, with the inlet for cold air facing one side and the hot air outlet facing the other. The line formed by the front end of the rack is called the cold aisle. Typically, the cold aisle faces the output duct of the air conditioner. The row of hot air output is called the hot aisle. Typically, the hot aisle faces the return air duct of the air conditioner.


A closed system can be used to isolate hot aisle and cold aisle from mixing hot and cold air. The closed system acts like a physical barrier, separating the hot and cold channels with vinyl sheets or plexiglass. Currently, suppliers offer ventilation rooms and other commercial options that combine a closed system with a variable fan drive (VFD) to prevent mixing of cold and hot air.

Best practices for hot aisle cold aisle containment include:

1. 1.5 feet from the ground, so that the air pushed out by the air conditioner can pass.

2. Deploy a rack grill with 600 cubic feet per minute (CFM) output.

3. Position the device with the side and top exhaust pipes in their position in the data center.

4. Install an automatic door in the data center.
