直接芯片液体冷却：高密度数据中心热管理的未来
数据中心的功率密度已飙升至每个机架 12-30 kW，因此液体冷却至关重要。了解单相和两相直接芯片系统的工作原理、制冷剂选择标准以及现代高密度数据中心中软管、管道和接头的关键设计注意事项。
冷却塔均衡：工程基础和最佳实践
Cooling tower equalization is a critical engineering system that maintains hydraulic balance across multiple cooling tower cells through dedicated piped connections or internal flume boxes. External equalizers must be sized for 15% of the largest tower flow rate and positioned on the deep side of tower basins to prevent operational failures including air entrainment, pump cavitation, and reduced heat transfer efficiency. The system ensures consistent water levels between towers operating on common headers, with proper sizing ranging from 3″ for flows up to 120 GPM to 20″ for flows exceeding 6,930 GPM. Key design considerations include overflow elevation consistency, piping symmetry, valve placement for isolation capabilities, and cleanout provisions for bottom connections. External equalizers provide superior operational flexibility compared to internal flume boxes, justifying additional cost through enhanced maintenance accessibility and system reliability for complex installations.
平衡通风
Air Exchangers exchange stale indoor air with fresh air from the outside. Heat recovery ventilation (HRV) is a system that exhausts air from inside of a home and replaces it with outdoor air. Energy recovery ventilation (ERV) is a system that does everything that an HRV does with the addition of transferring moisture from the exhausted air into the air entering the home and restricting moisture from incoming air.

Balancing air systems (ductwork) may be accomplished in various ways. The most common method to accomplish ductwork balancing is Proportional Method. Each diffuser is adjusted to supply the right percentage of total air volume in the ductwork.

生命周期成本分析方法
The life-cycle cost analysis method is the most commonly accepted method to assess the economic benefits of energy conservation projects over their lifetime. Typically, the method is used to evaluate at least two alternatives of a given project (for instance, evaluate two alternatives for the installation of a new HVAC system: a VAV system or a heat pump system to condition the building). Only one alternative will be selected for implementation based on the economic analysis.

暖通空调控制图
In this blog post, we will introduce some of the most common HVAC control diagrams. We will also provide a brief explanation of each diagram and how its components work together. HVAC control diagrams are essential tools for designing, installing, and maintaining HVAC systems. They provide a visual representation of the system’s components, how they are interconnected, and how they are controlled. This information can be used to troubleshoot problems, optimize performance, and make informed decisions about system upgrades.
