Hot Aisle / Cold Aisle, this hot and cold aisle containment is actually in the data center. At most, it is mainly used to control the flow of air. This data center knows that there are many equipment and the heat generated when it is running is very high.
By establishing specific hot and cold channels, it is necessary to ensure that cold air can be effectively sent to the equipment and that hot air can be discharged quickly. Let’s talk about the basic concept first. Do we have a clear score on the hot channel and cold channel?
Next, let’s talk about the key content, which can be divided into several modules. First of all, this layout planning is very important. The location should be planned reasonably based on the size of the equipment and power consumption. In this way, avoid the strange problems of airflow reflux as much as possible. The placement is too messy, and the hot air may be sucked back by the equipment, so the refrigeration effect will definitely be greatly reduced. What rules should be arranged according to the equipment? The equipment should be distributed reasonably based on the equipment's refrigeration demand, and these equipment with large power consumption should be placed together. It feels like arranging seats. If you are a student from high and low classes sitting in the back, the light and other problems will not be solved. Allow the hot air flow to form a unified and smooth passage. For example, if the heat is out in a row, if it is mixed, it will not be able to form a stable and effective "track". And this cold passage is to ensure that the air supply is evenly enough to reach the equipment air intake. The air supply grille must be arranged in a reasonable manner, such as components!
The second module talks about physical partitions, and the choice of partition materials is too critical! It is necessary to have thermal insulation! Fireproof What is the function… Many materials have heat insulation functions but they are not fireproof. In our computer room! If the fire accidentally catches, the consequences will be unthinkable! So we have to take into account both fireproof functions and choose materials in many aspects. Effectively separate hot and cold air flow. Look at the partitions that were not properly set! The heat may have flowed into the cold channel. Therefore, some metals and glass have their own advantages and disadvantages, and they need to be comprehensively measured. When installing, you have to be more careful whether each board needs a gap… If there is a gap, then the air conditioner will be robbed by the heat. It's… It's definitely not possible to be effectively sent to the equipment location! Of course, the installation must be strictly followed by the relevant rules and regulations. If you install it randomly, it means that you spend money to show off, just like you can’t live in a house that you can’t live in at all!
The third module talks about what system the air conditioner is. The selected model must be able to adapt to the hot and cold channel layout, and the cooling capacity must be strong enough. If the air conditioner is not strong, no matter how good the layout is later, it will be nonsense! The air conditioner circulation must be coordinated with the hot flow and cold chain. Otherwise, the temperature of the equipment will not be reduced! During operation, you must always monitor the temperature changes. If there is any abnormality, please adjust the strategy as soon as possible. If the temperature rises immediately! That's not a small matter, you suddenly have a "fever". You have to find out where the disease is. Otherwise, the lifespan of the equipment will also affect the high temperature for a long time. The efficiency will naturally be reduced.
The question and answer format adds some details. Some people may ask how to determine the ratio of the length of the hot channel and the cold chain? In fact, there are no absolute authoritative standards, but the key is to look at the equipment power consumption and air conditioning efficiency in a comprehensive way. If you consider these situations as a whole, you will probably get a good solution. Some data centers have large power consumption so that the hot channel is appropriately lengthened, and the air conditioning can be supplemented a little later to make it more concentrated!
So should we add some heat removal measures to the hot channel? It depends on the specific situation! If the temperature is high, you can add a fan to guide the hot air flow to quickly discharge… but you can't get too close to the data device and easily get dust wrapped in! After all, data equipment is expensive, and once there is too much dust accumulation, it is easy to have problems.
There is another question that many people ask if partition design has style requirements? The style requirements can be said to be lacking. Hot Aisle/Cold Aisle Containment. First of all, we need to achieve the airflow separation function. On this basis, we can take into account the coordination of the appearance of the computer room. For example, it is better to look cleaner and more beautiful, because some customers may visit and look beautiful under the premise of stable operation of the equipment.
I just mentioned in many aspects that are similar to the content of this hot channel and cold channel, which many people are concerned about. But I personally think that in terms of actual operation, we should fully understand the equipment characteristics as much as possible, examine the successful experience of similar data centers, and then repeatedly consider the plan based on actual operation. The hot channel cold chain is set up reasonably, so it can create a high-quality operating environment for the equipment. This is definitely worth the effort and effort to make it more refined!
