The difference

The cold aisle has a small space and can open the environment to the hot air flow. The cooling capacity used to cool the environment is reduced. Although the ambient temperature is high, it can ensure the operating temperature of the server.

Its air flow temperature is higher, so the return air temperature of the air conditioner will be higher, which can increase the cooling capacity of the precision air conditioner. When there is a problem with the refrigeration system, the hot aisle closure can be used to deal with the cold air flow outside the computer room to ensure short-term cooling.

Features

1. Cold aisle monitoring technology confines the cold air to the small environment of the cabinet. The cold air must pass through the cabinet before it can be released into the computer room to achieve air circulation, which is conducive to heat dissipation of all equipment in the cabinet and can completely solve the problem of local overheating in the cabinet;

2. The cold aisle monitoring technology completely isolates hot and cold gases, increases the return air temperature, solves the dilemma of too low ambient temperature in the computer room and too high temperature of the cabinet equipment, avoids ineffective operation of air conditioners, and improves refrigeration efficiency and refrigeration effect;

3. Cold aisle monitoring technology can effectively reduce the P U E value of the energy consumption rate of the computer room, improve the efficiency of the data center, increase the storage density of cabinet equipment, and increase the volume ratio of IT equipment in the data center.                    

Cold air enters the computer room from vents in the floor or ceiling, flows through servers and equipment, absorbs heat, and is discharged again.

The cold aisle computer room can provide uniform temperature distribution to ensure that the equipment operates efficiently within the appropriate temperature range.

Cold aisle computer rooms are generally easier to achieve airflow control and heat dissipation management, providing higher energy efficiency and maintenance convenience.                  

1. The hot aisle maintains a relatively low temperature in the computer room by discharging hot air outside the computer room.

2. Hot aisle computer rooms are usually combined with efficient heat dissipation systems to ensure continuous and stable operation of the equipment.

3. Hot aisle computer rooms are suitable for densely deployed equipment and high-load applications, and can better control the temperature of equipment.
