Method for improving horizontal lateral air sending refrigeration efficiency

Abstract

The invention provides a method for improving horizontal lateral air sending refrigeration efficiency, and belongs to the technical field of calculating data central machine room refrigeration. The method includes the following steps of forming a refrigeration row cabinet through three STULZ CyberRow horizontal lateral air sending precise air conditioners and four high-thermal-density server cabinets by taking local-high-heat local processing as the thought, making the precise air conditioners run with two in one set and the other one in the other set when fully loaded, sending air from the single side, namely, the air conditioners at the two ends, of the CyberRow or the two sides, namely, the middle air conditioner, of the CyberRow, and closing air sending spaces and air return spaces of the precise air conditioners and the server cabinets to form independent passageways respectively through closing assemblies so that cold air flow and hot air flow which are generated by the row cabinet can be prevented from flowing and being sent to other areas of the machine room. The row cabinet closing assemblies are customized air flow loop assemblies matched with the server cabinets and the precise air conditioners on the machine room site. Due to the air sending spaces and the air return spaces of the closing assemblies, cold air or hot air is prevented from overflowing, and refrigeration efficiency is improved. The closing assemblies are detachably connected with the server cabinets.

Description

technical field [0001] The invention relates to a method for improving the cooling efficiency of horizontal and lateral air supply, and belongs to the technical field of cooling for computer rooms of computing data centers. Background technique [0002] In the past, the average load of a single server cabinet in the computer room was 3kw / cabinet, and the layout of the cabinets was arranged in a queue. The cooling of the computer room used traditional precision air-conditioning equipment. Cooling efficiency is low. [0003] With the use of high heat density blade server clusters, the heat load in some areas of the computer room reaches 13KW / cabinet. The traditional computer room cooling method (underfloor air supply, ceiling return air) can no longer solve the heat dissipation problem. The problem of local high heat density in the computer room environment has become a major problem for high-performance computing data centers. [0004] The traditional airflow distribution m...

AI Technical Summary

Problems solved by technology

Due to the limitation of the physical size of the air supply cross-sectional area under the floor and the effective air outlet area of ​​the floor air outlet (the air outlet floor cross-sectional area, through-hole ratio), it can only solve the problem that the load of a single cabinet is less than 5KW. After using blade servers in the computer room The problem of high heat density (single cabinet load 13KW)

Traditional refrigeration methods cannot meet the needs of high heat density
