The floor blowing data center air-conditioning system of system.
Background technology
Currently, most data centers take Under-Floor Air-conditioning System, air-conditioner wind is by floor plenum chamber and makes somebody a mere figurehead
Perforation floor on floor cools down server cabinet.Under-Floor Air-conditioning System has the characteristic of Thermal stratification, in reality
It only needs to consider to cool down workspace in the work of border, therefore relative to traditional upper air supply air-conditioner system, which send
Air temperature is higher, can save operation energy consumption；And the system can take away the hot-air of workspace to nonclient area, improve in room
Air current composition.
The configuration mode of current common Under-Floor Air-conditioning System has open type floor plenum chamber and in floor plenum chamber
Interior two kinds of setting air supply duct.Open type floor plenum chamber is the configuration mode that current most of data centers take, the configuration
Mode is easy to construct, and need not install additional air supply duct and end, and fan resistance is small, operation energy consumption is relatively low；However, ground
Plate plenum chamber there are problems that leaking out and heat fade, and certain influence is generated on air conditioning energy consumption；In addition, the flow field in the plenum chamber of floor
Sufficiently complex, air pressure is unevenly distributed, and air-flow is influenced by various barriers in plenum chamber, is caused to different location
Server cabinet cooling effect there are significant differences, and then lead to the generation of hot localised points phenomenon in cabinet.In floor static pressure
The configuration mode of setting air supply duct, which overcomes, in case leaks out and the problem of heat fade, and air-conditioner wind is by barrier in plenum chamber
Influence it is smaller, but the air flow resistance of the configuration mode is larger, increases energy consumption, and needs to coordinate end regulator
It can ensure that each air supply position air-supply is uniform.
The present invention proposes the collocation form that the tree-shaped air supply duct of T-type is arranged in the plenum chamber of floor.On the one hand, pipeline
Arrangement alleviates floor plenum chamber and leaks out and the phenomenon that heat fade, reduce influence of the barrier to air-conditioner wind, optimize air-flow
Tissue；On the other hand, the length and width of each section of pipe-line system meets certain mathematical relationship, is carried out to the arrangement of pipeline
Optimization so that the collocation form can reduce the flow resistance of air-conditioner wind, reduce energy consumption；On the other hand, due to T-type pipeline cloth
The flow resistance of the characteristics of setting form, each end of blowing is of substantially equal, the uniform journey of air current composition and the cabinet air-supply of air-conditioner wind
Very big improvement can be obtained in degree.
