Data center hot and cold channel isolation to improve energy efficiency

The research shows that in an unreasonable design data center, 60% of the air conditioner is wasted due to the unreasonable airflow organization. At present, the traditional open heat channel structure data center is confronted with two major airflow management problems: the mixture of hot and cold air and the waste of cold air supply. Both of these phenomena greatly reduce the efficiency of air conditioning refrigeration. Among them, the hot and cold air phase mixing phenomenon refers to the equipment generated by the hot air and air conditioner to mix the cold to improve the equipment into the wind temperature; The waste of cold air supply of air-conditioning refers to the phenomenon that the cold air supply of the air-conditioner does not enter the equipment, and the cooling of the equipment directly returns to the air-conditioner.

About the cold air leakage, generally occurs in a number of points in the data center, where most of the leakage occurred in the rack and other places, and the full closure of the cold channel will be able to greatly improve the efficiency of the data center, taking into account the server rack airflow optimization, all choose the right solution is more important

With the development of data center industry, the change of hot and cold channel is a normal. In the data center, the significance of the isolation of hot and cold channels plays an important role in saving energy effectively. Effective control in airflow organization to achieve optimal cooling performance. Closed hot channel, the air from the top of the cabinet discharged, in order to prevent air-conditioning by the server emitted by the hot gas mixed, so the cold channel must also be isolated.

The most common in the data center is the integrated wiring environment, a good data center wiring is based on specific needs to do, through the reasonable allocation and arrangement, effective control of cold air access, and not affected by the wiring system, further improve energy efficiency ratio. In high-density hardware data centers, such as the use of a large number of http://www.aliyun.com/zixun/aggregation/13737.html "> Blade server, more cooling using water-cooled." In the process, retrofitting and connecting water-cooled equipment is another key point.

This is not the only problem, data center cabinets in the development process is also evolving, including different degrees of ventilation, different depth width and height, in a large number of intensive server environment how to place to be able to increase the cooling efficiency again. In some data centers, the unreasonable cabinet is ultimately caused by the data center hot and cold air mixing, resulting in lower energy efficiency.

Also, the floors need to be noted that there may be structural changes to be made. Since it is necessary to assume the weight of the closed systems on the elevated floors, which undoubtedly increases the load on the floor, this is particularly important when proven through closed systems.

In the closed hot and cold passage of the transformation process, there are several problems to note, one is mentioned above the weight problem, the second is the outlet between each cabinet, the ideal case is strictly in accordance with the advance plan to make, reduce the chance of hot spots appear. The third is the problem of the cabinet, in extreme cases, you may be able to do a little bit of the cabinet movement, so that the most appropriate solution, of course, first of all in the actual process to find problems, so that the Commission solution to deal with.

The hot and cold channel closure scheme is a kind of cooling method used in large data centers, especially in high density data centers in recent years. This scheme effectively solves the problem of the high density cabinet cooling, reduces the risk of the downtime caused by the overheating of the equipment, the design of the fire-fighting linkage, and solves the fire risk problem.
