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.

طرفداران: خط اول خنک کننده

هواداران، درست مانند بادگیر در زمستان، هوای متحرک به سرعت دمای پوست ما را کاهش می دهد، به خصوص زمانی که تبخیر تعریق نیز شامل شود. حتی خانه هایی که از تهویه مطبوع استفاده می کنند نیز می توانند از استفاده از پنکه بهره مند شوند. خنک کردن بدن با یک فن به این معنی است که می توانیم دمای کولر گازی را افزایش دهیم و در کل انرژی را ذخیره کنیم. انواع مختلف پنکه: فن های قابل حمل، پنکه های جعبه ای یا پنجره ای، پنکه های سقفی، پنکه های تمام خانه، پنکه های اتاق زیر شیروانی. #فن #پنکه قابل حمل #پنکه باکس #پنکه سقفی #هوادار کل خانه #پنکه زیر شیروانی #تخریب

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.

فرصت های شغلی تهویه مطبوع

The HVAC/R (heating, ventilating, and air conditioning / refrigeration) industry is rapidly changing due to advancements in technology being spurred on by the need for increased energy efficiencies. Accordingly, the career opportunities open to an individual seeking employment in HVAC fields can be divided roughly into four categories, each dependent upon a different type or degree of education and/or training.

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.

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.
