Fabric duct solution unburdens data center build-outs part 1

Cooling build-outs can be one of the highest operational costs facing data storage facilities. However, executives at San Diego-based redIT says it has implemented a new cost-saving measure at its data centers. The new procedure involves adding cooling drops for individual partitions inexpensively, and only as new customers come onboard.

To ensure redundant capacity, datacenter construction requires a complete and expensive build-out of a space’s HVAC system, including ductwork and diffusers. Because it may take years to lease out the entire space, this upfront cooling build-out can be a costly practice. redIT officials have found a short-term, more cost-effective alternative by installing each sheet metal drop and diffuser only after a customer comes onboard. This approach postpones construction costs while saving data centers time and resources.

That said, this phased sheet metal construction approach also has disadvantages. Sheet metal construction creates airborne particulates and poses other unnecessary risks to neighboring computer equipment. It also costs thousands of dollars in installation labor and material associated with each new cooling drop. Additionally, outsourced sheet metal contractors in highly restricted access control areas can potentially jeopardize security efforts.

redIT, operating multi-tenant facilities with many Fortune 500 clients, realized these challenges. Furthermore, the firm wasn’t satisfied with the prices, performance, or flexibility of conventional CRAC air distribution systems.

redIT used this cost-saving phased cooling approach during the build-out of the first 14,800-sq-ft datacenter phase of its 88,000-sq-ft facility in San Diego. The HVAC service contractor, Countywide Mechanical Systems, introduced fabric ductwork to redIT’s design team. The team included Mark Hopperton, chief technology officer, and Gabriel Faulkner, facility manager.

Factory engineers from fabric duct manufacturer DuctSox Corp., and the redIT team, partnered with Gilbert Dominguez, manager of manufacturer’s representative Toro-Aire, to design a custom-fabricated fabric ductwork drop as an alternative to conventional sheet metal drops. The application was the first case for the manufacturer where a custom-fabricated, inverted T-shaped fabric fitting was used for data center equipment spot cooling.

Fabric Underfloor Air Dispersion for Efficient Cooling in Buildings

With over 80 per cent humidity in Indonesia all year round, fabric duct for underfloor air dispersion is an ideal alternative to conventional metal ducting for more efficient cooling. Efficient and effective cooling is necessary to create comfortable indoor environment while keep cost at reasonable amount.
Fabric underfloor air dispersion system is a unique method for delivering conditioned air in buildings or spaces. Ideal for high rise buildings, offices, hospitals, hotels, schools, airports and other commercial buildings. DuctSox has specifically developed UnderFloorSox (UFSox) to distribute and disperse air to perimeter and high-heat load locations in under floor air distribution systems.
Unlike conventional overhead air-mixing systems, fabric duct for underfloor air dispersion system use the space beneath the raised access floor as a plenum to introduce air into occupied space, usually through special floor-mounted diffusers. Fabric duct for underfloor cooling are becoming increasingly accepted in commercial buildings space as the benefits, which are well documented by ASHRAE, can include:
- Improved employee comfort
- Reduced energy costs
- Improved indoor air quality
- Improved productivity and health
- Reduced floor to floor heights
- Reduced life cycle building costs

Fabric duct for underfloor cooling are based on displacement ventilation principles, requiring that the air stratifies from the floor to the ceiling, where it is either exhausted or recycled back into the space. New construction projects using fabric duct for underfloor cooling technology frequently qualified for LEED credits and green rating by Green Building Council for increased ventilation 'effectiveness'.
Key advantages of UnderFloorSox systems by DuctSox are:
- Even air dispersion: this continues to be a significant features and advantage of fabric air dispersion systems versus metal. Engineered vents and/or orifices and variable endcaps are designed to meet your application providing high entrainment rations and uniform air dispersion patterns (low velocity). These advantages maintain temperature control both under and above the raised access flooring,especially in extended distance locations.

- Air porous fabric: UnderFloorSox by DuctSox reduces heat loss (temperature gain) or thermal decay over extended distances and to perimeter zones. Additionally, porous fabrics eliminate the risk of condensation to the ductwork.

Keuntungan Memasang Kipas Angin HVLS

Sudah familiar dengan kipas angin HVLS dari BladeTec?

Beberapa keuntungan dari memasang kipas HVLS ini adalah:
- Kualitas udara yang lebih baik
- Kadar kelembapan yang lebih rendah
- Berkurangnya bakteri-bakteri jahat
- Udara yang lebih bersih dan sehat

Cara terbaik untuk membandingkan udara pengap dan tak bergerak dengan udara yang bersih dan beredar merata dalam ruang dengan baik adalah dengan membandingkan dengan sungai. Sungai serring dianggap sebagai sumber air yang jauh lebih aman daripada kolam yang airnya tidak bergerak. Selain itu, upaya ekstra sering diperlukan untuk membersihkan kolam. Hal yang sama juga berlaku bagi udara yang kita hirup. Ketika beredar dengan baik, udara akan menjadi lebih bersih, lebih aman, dan kadar kelembabannya berkurang.

Kipas angin bervolume tinggi berkecepatan rendah (HVLS High Volume Low Speed fans) memberikan lebih banyak keuntungan dibandingkan dengan kipas angin tradisional kecil berkecepatan tinggi. Kipas angin kecil berkecepatan tinggi akan segera ketinggalan zaman karena begitu banyaknya manfaat yang dapat diberikan oleh  kipas angin HVLS.

Kipas angin HVLS dari BladeTec terutama memberikan penerapan ramah lingkungan bagi gudang dan bangunan komersial lainnya. Hal ini memungkinkan pemilik usaha mendapatkan hasil maksimal dari peralatan dan barang-barang mereka, sekaligus melindungi dan melestarikan energi dan bahan yang disediakan alam. Banyak perusahaan yang mulai melakukan praktik ramah linkungan, tidak hanya untuk memperbaiki lingkungan dan masyarakat mereka, namun juga krena sekarang pemerintah menyediakan imbalan dan insentif bagi praktik-praktik cerdas tersebut. Perusahaan juga akan mendapatkan imbalan untuk penghematan yang dapat dilakukan dengan adanya praktik ramah lingkungan.

Ingin mencoba kipas HVLS dari BladeTec? Kipas HVLS BladeTec tersedia dalam berbagai ukuran untuk menyesuaikan dengan kebutuhan Anda. Hubungi Tawada CleanTech di 021 5794 1139 atau email ke marketing (at) tawadacleantech (dot) com untuk info lebih lanjut.
