Information technologies such as big data, AI, and industrial Internet are changing with each passing day. In order to meet the needs of new business development, it is urgent to strengthen the construction of data centers and promote business development. The Sugon Data Center product line has a complete product line portfolio that can cover a wide range of application needs and provide users with a “one-stop” data center solution.
Traditional Low-Density Data Center Construction Solutions
The data center room is the basic infrastructure protection of IT facilities running. The construction of room mainly includes decoration system, power distribution system, air conditioner fresh air system, lightning protection and earthing system, monitoring and management system, fire alarm system, integrated wiring system. The air conditioning system is the environment protection of the data center room running. Because a large number of network and computer equipments are stored with high density in the data center room, a lot of heat is not only produced, but the requirements on humidity, dust quantity and size in the environment are high, which put forward higher requirements for air conditioning system.
According to the classification of air conditioning application, they can be divided into two kinds of comfort air conditioning and process air conditioning, the former is mainly designed for human life and work, the latter is for the particular requirements for temperature and humidity, air cleanliness, operating conditions etc. Precision air conditioning is designed for the characteristics and environmental requirements of data center room, communications room, and belongs to process air conditioning.
To sum up, the environment of room is required to be stable and reliable, and specific precision air conditioning can be adopted to achieve this goal. Although comfort air conditioning units reduce the initial investment, they are unable to ensure the constant temperature and humidity, air cleanliness and ventilation in the room.
Air supply of room air conditioning system in data center is divided into two ways, room air supply and cabinet close range air supply. The latter is mainly used for high heat density cabinet refrigeration, and the former applies to the conventional environment of a single cabinet heat density less than 10KW. Air supply airflow organization in room include under-floor air supply, air supply on the hood and duct air supply. Under-floor air supply is the most important way among them with the characteristics of cooling efficiency, ease of installation and clean.
The cool air from air conditioning in the room flows into the space under static floor forming a big static pressure box under the floor. The cool air will be delivered to the front of the server cabinet by the hole-floor, inhalation by server equipment through cabinet mesh door. The hot air discharged by the cabinet will be naturally replaced by the cool air or delivered to the air outlet at the top of air conditioning through channel ceiling, air duct completing a refrigeration cycle.

The cabinets will be arranged as face-to-face and back-to-back to form the hot and cold aisles. You can set ventilation floor with enough holes with large ventilation rate in the cold channel side of the cabinet. The floor ventilation rate can be adjusted according to the different heat load, or fix the ventilation floor location. It will not place ventilation floor in the hot channel side of the cabinet.
In order to ensure the cabinet temperature and humidity of the proximal and distal air conditioners is uniform, reduce wind resistance under the floor and improve the cooling efficiency, usually, the following measures can be taken:
1）Improve the height of floor placed from 300mm to 400 or even 600 to 1000mm;
2）The layout of electrical wiring is adjusted as the upper alignment, dedicated to be plenum box under the floor;
3）To close cold aisle or hot aisle to effectively cut off from the hot and cold air to prevent air short-circuit;

4）To increase the air containment fittings, you can increase the air supply refrigeration to 10KW high power density within the cabinet, such as floor ADU. Floor ADU is with function of forced air blowing, containing the unit floor outlet of cabinets, high porosity, and strong wind capacity for the down air distribution system, which can improve the air volume of individual floor vents to solve individual high density cabinets with wind.
The Green Rack cabinet-level micro data center is designed according to the standard of the data center computer room. The cooling, power distribution, monitoring, wiring, UPS and battery modules are integrated into one or more cabinets to form a cabinet-level micro data center, widely applied in monitoring, medical, broadcasting, communications and financial industries.
The Green Pool cabinet pool-level micro data center integrates cabinets, power distribution, cooling, wiring, and monitoring subsystems. It provides two options: closed cold pool and closed hot pool according to the cold and hot air flow in the closed channel. The density range is from 3 to 10 kW in a single cabinet, suitable for medium and low density data centers.
The GreenRow cabinet is equipped with a micro data center, which integrates cabinet, power distribution, cooling, wiring and monitoring systems. It adopts a fully enclosed design. The interior uses the inter-row air conditioner to cool nearby. The cold and hot air flow channels are isolated in the cabinet, and the heat exchange efficiency is greatly improved. The power density of single cabinet can reach up to 30kW, which perfectly matches the construction needs of medium and high density data centers.
