从罐体到系统整体设计

Explore how stratified TES tanks, engineered water diffusers, optional flow-management baffles and chiller plant integration work together to deliver flexible cooling capacity.

了解分层式 TES 储能罐、低扰动布水器、按需设计的导流板,以及冷水机房集成如何协同实现灵活的供冷能力。

01 / TES TANK CROSS-SECTION

Designed for stable temperature stratification以稳定温度分层为设计核心

A stratified chilled-water TES tank stores warmer return water above colder supply water. A transition zone, called the thermocline, separates them. Carefully engineered upper and lower diffusers distribute flow at low velocity to reduce unwanted mixing.

分层式冷冻水 TES 储能罐中,较暖的回水位于上层,较冷的供水位于下层,中间为温度过渡层(Thermocline)。上下布水器通过低流速、均匀布水,减少冷热水混合。

Baffles may be incorporated where hydraulic analysis shows a benefit. Temperature sensors at multiple elevations help monitor thermocline movement and state of charge.

导流板是否采用及其布置,应依据水力分析确定。不同高度的温度传感器可用于监测温跃层移动和储能状态。

02 / DIFFUSER ENGINEERING

Uniform flow. Minimal mixing.均匀布水,降低混合

Low-velocity water distribution低流速布水设计

Diffusers spread incoming and outgoing water across the tank section. Their geometry, openings and discharge velocity are engineered for the required flow range and temperature difference.

布水器将进出水流分配到储能罐截面。布水臂、开孔与出口流速需根据设计流量、温差及工况进行计算。

03 / BAFFLE ARRANGEMENT

Flow management where it matters按需配置导流板,改善水力分布

Segmented baffle plates can be considered to redirect local currents and manage recirculation. They are not a universal requirement: poorly designed plates may increase pressure loss or worsen mixing.

分段式导流板可用于调整局部水流路径及回流区,但并非所有 TES 储能罐都必须安装。设计不当可能增加压损,甚至加剧混合。

HULKEN's proposed engineering workflow evaluates baffle placement together with diffuser performance, structural support, maintenance access and hydraulic losses.

HULKEN 的设计流程建议将导流板布置与布水器性能、支撑结构、检修空间及水力损失一并评估。

01 · Charge / 蓄冷

Chillers produce cooling to charge the tank; colder water accumulates toward the bottom as the thermocline moves upward.

冷水机组向储能罐蓄冷,低温水从底部逐步增加,温跃层向上移动。

02 · Discharge / 放冷

The tank supplies chilled water to support the cooling load while warmer return water enters the upper region.

储能罐释放冷量支援建筑负荷,较暖回水进入罐体上部。

03 · Control / 控制

Pump sequencing, valve positions, temperature monitoring and plant optimisation coordinate the operating modes.

通过水泵联动、阀门切换、温度监测及冷站优化协调运行模式。
