Floor air supplying data center air conditioning system integrated with T-type tree-shaped air supplying pipeline system

Abstract

The invention discloses a floor air supplying data center air conditioning system integrated with a T-type tree-shaped air supplying pipeline system. The floor air supplying data center air conditioning system comprises the components of a precise air conditioner, an elevated floor, server cabinets and a closed cold channel which are above the elevated floor, a T-type tree-shaped air supplying pipeline system, a variable-diameter pipe and an air conditioning air outlet pipe which are arranged below the elevated floor, and a floor air supplying diffuser which is arranged on the elevated floor.According to the floor air supplying data center air conditioning system, conditioning air is concentrated and distributed through the T-type three-shaped structured air supplying pipeline system; theserver cabinets are arranged according to the T-type tree-shaped structure of the air supplying pipeline system; and furthermore the cold channel is closed. The floor air supplying data center air conditioning system has advantages of realizing uniform air supplying to each server cabinet in a data center, reducing occurrence of local hot points of the cabinet, reducing air supplying resistance of the air conditioning system, and reducing energy consumption of the air conditioning system.

Description

technical field [0001] The invention belongs to the technical field of data center air conditioners, and in particular relates to a floor air supply data center air conditioner system integrated with a T-shaped tree-shaped air supply pipeline system. Background technique [0002] At present, the vast majority of data centers adopt the floor air-conditioning system, and the air-conditioning air cools the server cabinets through the floor static pressure box and the perforated floor on the raised floor. The floor air supply air conditioning system has the characteristics of thermal stratification. In actual work, it only needs to consider cooling the work area. Therefore, compared with the traditional upward air supply air conditioning system, the air supply temperature of this system is higher, which can save energy consumption ; And the system can take the hot air from the working area to the non-working area to improve the airflow in the room. [0003] Currently, there are...

Problems solved by technology

The open-floor plenum is currently the configuration method adopted by most data centers. This configuration method is easy to construct, does not need to install additional air supply ducts and terminals, and has small air supply resistance and low energy consumption; however, the floor static There are problems of air leakage and heat attenuation in the pressure box, which have a certain impact on the energy consumption of the air conditioner; in addition, the flow field in the floor static pressure box is very complicated, the air pressure distribution is uneven, and the air flow is affected by various obstacles in the static pressure box , leading to significant differences in the cooling effect of server cabinets in different locations, which in turn leads to the generation of local hot spots in the cabinet

The configuration method of setting air supply ducts in the floor static pressure box overcomes the problems of air leakage and heat attenuation, and the air-conditioning air is less affected by obstacles in the static pressure box, but the air flow resistance of this configuration method is relatively large, which increases the energy consumption, and it is necessary to cooperate with the terminal pressure regulating device to ensure uniform air supply at each air supply position
