بررسی اهمیت سیستم فیلتراسیون اتاق سرور

چرا کولر گازی انتخاب مناسبی برای تعدیل دمای سرور روم نیست؟

بررسی اهمیت سیستم فیلتراسیون اتاق سرور

یکی از ارزشمندترین موارد در سیستم های زیرساخت مراکز داده ، فیلتراسیون اتاق سرور است. گاهی بخاطر قیمت بالای سیستم های کولینگ تهویه، از کولرهای گازی استفاده می شود که انتخابی پرخطر می باشد. در این بخش به علل اشتباه بودن این انتخاب و فواید استفاده از فیلتراسیون اتاق سرور خواهیم پرداخت. با طیف نیوز همراه باشید… .

تهویه سرور روم

مراکز داده باید مرتبا از لحاظ میزان آلودگی کنترل و بررسی شوند که برای این منظور اصولا از فیلتراسیون اتاق سرور و در واقع فیلترهای کنترل غبار با توجه به رده بندی MERV به کار گرفته می شوند. اگر دستگاه ها سرمایش مخابراتی و تهویه دقیق باشند، از فیلترهای قابل شست و شوی 4G استفاده می شود و چنانچه میزان آلودگی و گردوغبار بیشتر باشد، فیلتراسیون سرور روم ارزشمند تر شده و از فیلترهای بیشتر و با رده بندی های متفاوت استفاده می شود.

کولرهای گازی، چون فشار فن ثابتی داشته و یک فیلتر پلاستیکی دارند، نمی توانند شرایط استانداردی از لحاظ فیلتراسیون اتاق سرور ایجاد کنند.

چرا کولرگازی انتخاب مناسبی برای تعدیل دمای مراکز داده نیست؟

1. شرایط استاندارد و الزامات فیلتراسیون سرور روم با استفاده از کولر گازی قابل تأمین نیست
2. کولرهای گازی نسبت به ظرفیت سرمایشی خود از میزان هوادهی کمتری برخوردارند، و این امر طبیعی است چون مناسب کامفورت ساخته و طراحی شده اند.
3. کولرهای گاز مرتبا رطوبت هوا را تقطیر می کنند و قادر به حفظ رطوبت مراکز داده مانند فیلتراسیون اتاق سرور نخواهند بود.
4. تفاوت فشار دو سر کمپرسور در سیستم تهویه مطبوع میزان بیشتری دارد نسبت به تهویه دقیق و دستگاه تهویه دقیق با تنش و فشار کمتری کار می کند.
5. به جز کولر گازی اینورتر که کاربرد آن نیز ریسک بالایی دارد، کولرهای گازی در فصل سرما نمی توانند سرمایش را تأمین کنند و روشن نمی مانند. کمپرسور مدل اینورتر در زمستان در خطر مایع کشیدن و خرد شدن پره های داخلی می باشد.

با این اوصاف اگر قصد فیلتراسیون سرور روم را دارید استفاده از کولرهای گازی کاملا مردود است و هزینه های پنهان زیادی دربر خواهد داشت.

    Categories of Dog Beds:

    Orthopedic Beds: Right for geriatric dogs or for dogs who
    are arthritic, delivering the support via the memory foam.

    like to have their heads supported.

    and any specific requirements. Locate good, wipe-easy material that will withstand a bit of
    time and which will offer supportive needs. Infrequent washings keep them fresh

  30. Beneath you’ll discover my favourite four workouts together with video demonstrations. Sharpening up the highest of your physique is the key to attaining the coveted V-shape, and no quantity of running, sit-ups or squats goes to provide you shoulders worth writing house about. Hopefully you’re now feeling inspired and are raring to go with a sensational shoulder session. They supply plenty of adjustments for the plates so you can get in that vertical place to get your shoulder aligned. If the exercise still feels uncomfortable, or you’re looking for an alternate, you should check out the monkey row. It’s some of the popular compound movements for this reason.
    Cable external shoulder rotations are the antidote to all that medial rotation. They may also help stop or alleviate the shoulder pain attributable to rotator cuff imbalances. Doing them with a cable somewhat than dumbbells means your deltoids are underneath almost fixed pressure. It’s also harder to cheat with this exercise than it’s when utilizing free-weights. All in all, it is a very effective anterior deltoid exercise.
    Make certain you’re not bringing your shoulder forward as you curl the weights up. Doing so shifts some of the work from your biceps to the entrance of your shoulders. Don’t be shocked if you must use a considerably lighter weight when doing incline dumbbell curls compared to when you stand or sit upright. The incline curl locations your bicep muscle in a weak position, and even comparatively mild dumbbells might be sufficient to place most stress on it. In regular dumbbell curls, you raise each dumbbells concurrently, however with alternating dumbbell curls, you carry one dumbbell at a time, alternating between your left and right. Doing so enables you to focus more on every arm individually and might help you pay more consideration to good type.
    With minimal shoulder joint stress however maximal muscle activation, it’s an efficient way to train your delts even in case you have painful shoulders. Choose a few dumbbells and stand with them by your sides, palms dealing with your physique. Keeping your higher physique nonetheless – that means no swinging – carry the dumbbells out to your facet with a slight bend at your elbows.
    But if you’re severe about full, balanced muscle development, you can’t afford to neglect your rear delts. If accomplished correctly, adding the dumbbell front raise to your shoulder workouts will help improve shoulder muscle symmetry and strength. If building your pushing strength is a aim, front raises are an excellent shoulder train to assist. They construct strength for movements such as the bench press whereas enhancing shoulder stability and mobility by working the stabilizing shoulder muscles. Using cables retains your muscle tissue beneath tension for the whole rep, which ought to be better for hypertrophy. Training one side at a time means you can actually focus in your medial deltoid and make sure that each shoulders are skilled equally. Bear in thoughts that it is a difficult session designed for individuals with extensive training expertise who want to build critical dimension and strength of their shoulders.
    Examine out our articles on the most effective cable shoulder workouts or these barbell shoulder exercises. Plus, you’ve already accomplished a standing overhead press with the push press, so it is good to throw some position selection into the combination. It Is a strong move that uses explosiveness to propel the load upward, which should enable roughly 30% more weight than a normal shoulder press. When performing isolation workouts, I choose utilizing the cable machine over dumbbells as it permits a clean, consistent pressure from any angle. The overhead press is notoriously tricky as a outcome of biomechanics, and because of this, many lifters just tend to avoid it. But, remember, your shoulders will all the time be weak should you do not prepare them.
    As with the opposite shoulder workouts, begin off with a light weight, as you’ll slowly however certainly feel increasingly fatigued as you work your method via the repetitions. The dumbbell shoulder press primarily works the entrance deltoids. By using dumbbells, you pressure all sides of the muscle to work independently while additionally recruiting the stabilizer muscles of the shoulder joint. Constructing robust, well-defined shoulders is vital to attaining the long-lasting Alpha male physique. Broad shoulders provide the width that enhances the striking V-shaped higher physique. With all three deltoid muscle heads totally developed, you’ll seem powerful and broad, whether or not you’re rocking a t-shirt or dressed up in a swimsuit. As A Substitute, you need to raise your arms keeping them straight with palms going through the ground, and raise them out to the side by initiating the contraction from the deltoids.
    The posterior deltoids – positioned on the back of your shoulders, the posterior or rear delts oppose the anterior deltoid. They are liable for extension, horizontal extension, and external rotation of the shoulder joint. Acting as a synergist or helper muscle, the anterior deltoids work together with your pecs whenever you do bench presses, push-ups, flyes, dips, or crossovers. The shoulder is a “ball-and-socket” joint between the upper arm’s humerus bone and the scapula bone (shoulder blade). The dumbbell lateral increase with a lean offers you increased stability and vary of motion as the gap your arm has to travel to carry out the lateral raise is additional. This higher range of motion with a robust contraction of the lateral deltoid results in more pressure and more features than the standing or sitting variation. Lateral raises require you to lift weights out to the aspect and away out of your body.
    Additionally, as a result of you’re pulling the load at a diagonal angle, you’re not allowing your biceps any possibilities to chill out and relaxation. The incline dumbbell curl would possibly look just like common dumbbell curls, however the incline of the bench is the secret sauce that turns this exercise into a unique biceps blaster. The dumbbell curl may be performed standing or seated, whichever you like. In addition, you can curl both dumbbells on the same time or alternate between sides. If you had to choose only one exercise in your biceps, the dumbbell curl would be an excellent alternative.
    This exercise benefits anyone utilizing an upper-body strength exercise. Nothing screams sheer energy like a few well-developed traps. You can have great arms and shoulders, but if your traps aren’t up to snuff, your physique will just look…missing. Typically neglected with direct focused work, the trapezius muscular tissues add thickness to the again in addition to present stability for overhead movements and enhance upright posture. The finest train for deltoids will concentrate on isolation movements for each individual head of the muscle.
    Named after the world’s most well-known Arnold (yes, Schwarzenegger), this variation of the overhead press increases vary of movement and hits all three heads of the deltoids. Remember to rotate your workouts for balanced improvement and continuous enchancment. At All Times begin with warm-up sets to prepare the muscle tissue and forestall damage. Pay consideration to kind and method, particularly when lifting heavy weights. Building stronger, fuller shoulders requires an understanding of the deltoid muscle’s anatomy. This muscle includes three heads – anterior, lateral, and posterior – each needing particular workout routines for balanced growth. Time to actually test these side delts now with some lateral raises.
    You ought to by no means hit snooze on a heat up, however for shoulder workouts, a warm up is much more important! As mentioned, the shoulder is a complex joint, which makes it particularly susceptible to injuries, strains, and dislocations. Taking 5-10 minutes to properly heat up the shoulder joint initially of your workout could be fundamental in stopping harm and making certain an excellent range of movement. You Are in all probability beginning to see a pattern now with these isolation shoulder exercises…
    Per workout session, it is recommended to carry out 3-4 completely different shoulder workout routines. You can add single-arm exercises when doing a shoulder exercise with a dumbbell at home to appropriate potential imbalances. Right Here are some other good ways to do dumbbell shoulder presses at house.
    That can help to create the definition between the arm and deltoid that makes the shoulders pop right off of the arm. This variation of the lateral elevate helps to restrict using the supraspinatus muscle to put extra of the emphasis on the middle head of the delts. To carry out the train, merely maintain onto a stable construction (like an influence rack) with one arm and lean away at about a diploma angle.
    The resistance from the bands helps to isolate the rear delts, making each rep count towards better definition and energy. Incline Rear Delt Rows stand out as a result of they isolate the rear deltoids in a method few exercises can. By positioning your self on an incline bench, gravity works differently, placing the emphasis squarely on the rear deltoids. It’s this particular physique alignment and movement that makes your rear delts work tougher than ever.
    Are you tired of doing the same workout routines and never making any gains? The shoulder muscle, or deltoid, is fairly small – it does not need ten totally different exercises to grow. The reality is, you can build the biggest boulders with simply three exercises. In this article, we’ll show you the only three exercises you should create the most monumental boulder shoulders of your life. Clearly, when it comes to hitting shoulders I’m by no means short on options. However for those whose shoulders are actually lagging, or anybody who wants to convey their delts out much more, I’ve designed a whole program round doing just that.
    This can hold your shoulders from rounding forward and also activate the rear delts. Upright row prompts all main shoulder muscular tissues, making it glorious for upper physique stability and conditioning. It is important to do this frequently to enhance your posture and shield yourself from harm.
    Keep In Mind, with TRX workouts it’s necessary to maintain your body in a relatively straight line across your heels, hips, and shoulder blades. All of those can be used to load some weight if you’re at house and don’t have entry to dumbbells/barbells. With these exercises you can undoubtedly develop nicely defined cap-like shoulders with full frontal, middle, and again shoulder heads. If you have a pair of dumbbells and a TRX suspension coach, it could help. You ought to train your trapezius muscle tissue twice per week, with a spot of hours between classes. In this article, I’ve carefully curated the 12 finest dumbbell workouts you are able to do at house for full trap development.
    That being stated, the shoulder is a delicate joint, and even if you aren’t doing a dedicated shoulder workout, you’ll still be coaching your shoulders during compound lifts. Take this into consideration when calculating your total weekly quantity, and unfold your shoulder workouts over multiple days to keep away from overtraining. Being that the deltoid is a three-headed muscle, you will want to work every of these heads equally so as to result in proportional and complete growth. All of the extra work that these two deltoid heads obtain can often result in the facet (lateral) head falling behind.
    As Soon As you’re into your exercise, you should manage the load you’re lifting. If you begin to struggle, drop the weight or pickup a lighter possibility. Go onerous or go residence might work for some muscles, but in phrases of shoulder exercises it’s just not worth it. This exercise strengthens the rear delts and improves shoulder stability, decreasing the danger of harm.
    This increases the volume of labor demanded on your upper body and might result in quicker progress in comparability with just engaged on the higher body as soon as per week. With this ultimate shoulders and arms workout routine, you’ll hit quite so much of exercises utilizing quantity, frequency, and intensity to optimize your upper body features. It offers you a extensive range of movement as you decrease the dumbbells properly down in entrance.
