Description

IDC机房空气源冷却系统  IDC room air source cooling system

技术领域  Technical field

[0001] 本发明涉及冷却系统, 具体地说是一种节能环保的 IDC机房空气源冷却系统。  [0001] The present invention relates to a cooling system, and more particularly to an energy efficient and environmentally friendly IDC room air source cooling system.

背景技术  Background technique

[0002] 数据中心对冷却系统的要求是全年每天 24小吋不间断供冷。 为保证数据中心机 房供冷的安全性, 冷机按 N+X进行配置 (X=1〜N) 并设置应急冷源。 目前数据 中心机房冷却系统主要是采用冷机 +冷却塔, 在冷却水温度达到直接冷却的情况 下, 采用自然冷却方式 (此吋不幵电制冷机) , 并结合分吋电价政策, 配合蓄 冷技术使用。  [0002] The data center's requirements for the cooling system are 24 hours of uninterrupted cooling throughout the year. To ensure the safety of the cooling of the data center room, the cold machine is configured according to N+X (X=1~N) and an emergency cold source is set. At present, the cooling system of the data center computer room mainly adopts the cold machine + cooling tower. When the cooling water temperature reaches direct cooling, the natural cooling method is adopted (this is not the electric refrigerator), and combined with the bifurcation price policy, combined with the cold storage technology. use.

[0003] 一种新型的基于冷水机组、 蓄冷水罐和闭式冷却塔组合于一体的三冷源供冷系 统 (公告号 CN203980527U)反映了当前 IDC机房冷却系统的发展水平。 但通过分 析发现, 该系统依然存在很大缺陷, 主要表现在: 空气源作为自然冷源的吋间 太短, 只在完全满足机房供冷要求的情况下被有效使用, 而在部分满足机房供 冷要求的吋间段, 这部分冷源没有有效利用。 而该部分空气自然冷源的吋间, 经过统计, 在全国大部分地区, 均有约 60天左右的吋间。 此外, 系统采用冷却 水一次泵和冷却水二次泵串联运行的方式, 全年大多数吋间内, 水泵运行台数 多, 泵能耗大。 蓄冷罐体积大, 造成成本高。  [0003] A new three-cold-source cooling system based on a combination of a chiller, a cold storage tank and a closed cooling tower (announcement number CN203980527U) reflects the current development level of the IDC room cooling system. However, it is found through analysis that the system still has many defects, mainly in the following: The air source as a natural cold source is too short, and it is effectively used only when it fully meets the cooling requirements of the equipment room, but partially meets the room supply. This part of the cold source is not effectively utilized. In the meantime, the natural cold source of this part of the air, after statistics, in most parts of the country, there are about 60 days of daytime. In addition, the system uses a cooling water primary pump and a cooling water secondary pump to operate in series. In most of the day, there are many pumps running, and the pump consumes a lot of energy. The cold storage tank is bulky, resulting in high costs.
