خنک کننده مایع مستقیم به تراشه: آینده مدیریت حرارتی مرکز داده با چگالی بالا
چگالی توان مرکز داده به 12 تا 30 کیلو وات در هر رک افزایش یافته است که خنک کننده مایع را ضروری می کند. با نحوه عملکرد سیستم های تک فاز و دو فاز مستقیم به تراشه، معیارهای انتخاب مبرد و ملاحظات طراحی حیاتی برای شیلنگ ها، لوله ها و کوپلینگ ها در مراکز داده مدرن با چگالی بالا آشنا شوید.
متعادل کننده جریان هوای کانال
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.
ویژگی های شیر
چرا باید از ویژگی های شیر آگاه باشیم؟ هر جزء در یک سیستم هیدرونیک سطحی از تأثیر را بر کنترل و عملکرد یک سیستم هیدرونیک دارد. سوپاپ ها کلیدی هستند زیرا دستگاه های کنترل کننده در مناطق بحرانی انتقال حرارت هستند.

این پنج سری از انتشارات شامل Emerson Climate Technologies, Inc. Refrigeration Manual است. اگرچه هر بخش جداگانه، حوزه خاصی از تئوری و عمل تبرید را پوشش میدهد، هر انتشار متوالی درک اساسی از مطالب ارائه شده در بخشهای قبلی را فرض میکند.
سیستم های ذخیره سازی یخ
Thermal energy storage (TES) involves adding heat (thermal) energy to a storage medium, and then removing it from that medium for use at some other time. This may involve storing thermal energy at high temperatures (heat storage) or at low temperatures (cool storage).
الزامات لوله کشی مبرد
This guide focuses on systems that use Refrigerant-22 (R-22). While the general requirements are the same for systems that use other refrigerants, velocities and pressure drops will differ.
روش تحلیل هزینه چرخه عمر
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.
