BladeTec untuk Tempat-Tempat Ibadah

BladeTec tidak hanya dapat digunakan di pabrik, kantor ataupun tempat ritel dan komersil. BladeTec pun dapat digunakan di tempat-tempat beribadah sekalipun. Duduk atau berdiri di satu tempat dalam waktu yang lama dapat menjadi tidak nyaman jika udara terasa sumpek. Tetapi dengan kipas biasa saja, suara bising yang dihasilkan dapat menganggu jalannya ibadah. Karena itu BladeTec adalah solusi yang tepat. BladeTec menghasilkan angin yang lembut dan tidak mengganggu berlangsungnya ibadah akan disambut dengan sangat baik oleh seluruh jemaat yang sedang beribadah.





Mengurangi biaya untuk menjaga tempat ibadah yang nyaman.
Menjaga
para jemaat agar tetap nyaman dapat membutuhkan biaya yang mahal, terutama di Indonesia dimana cuaca panas dan lembab hampir sepanjang tahun. Kipas langit-langit komersial BladeTec memberikan aliran udara yang sejuk dan lembut dan dapat menjangkau ke seluruh bagian tempat ibadah Anda. Jadi Anda tidak hanya menikmati lingkungan yang lebih nyaman, namun juga dapat mengurangi biaya pendinginan hingga 20%.

Pada bulan-bulan musim
hujan, kipas kami menggerakkan udara hangat dari langit-langit untuk meratakan suhu agar menjaga jemaat Anda hangat dan senang. Serta dapat membantu mengurangi kelembaban di udara dengan meningkatkan sirkulasi udara dalam ruang. Dan karena kipas HVLS BladeTec™ beroperasi dengan lancar dan tenang, Anda dapat melakukan ibadah tanpa gangguan.

Sekilas Under Floor Air Distribution UFAD


Underfloor air distribution (UFAD) is an air distribution strategy for providing ventilation and space conditioning in buildings as part of the design of an HVAC system. UFAD systems use an underfloor supply plenum located between the structural concrete slab and a raised floor system to supply conditioned air through floor diffusers directly into the occupied zone of the building. Thermal stratification is one of the featured characteristic of UFAD system, which allows higher thermostat setpoints compared to the traditional overhead systems (OH). UFAD cooling load profile is different from a traditional OH system due to the impact of raised floor, particularly UFAD may has higher peak cooling load than OH systems. UFAD has several potential advantages over traditional overhead systems, including layout flexibility, improved thermal comfort, improved ventilation efficiency, improved energy efficiency in suitable climates and reduced life cycle costs. UFAD is often used in office buildings, particularly highly-reconfigurable and open plan offices where raised floors are desirable for cable management. UFAD is appropriate for a number of different building types including commercials, schools, churches, airports, museums, libraries etc.[1] Notable buildings using UFAD system in North America include The New York Times BuildingBank of America Tower and San Francisco Federal Building. Careful considerations needs to be paid in the construction phase of UFAD systems to ensure a well-sealed plenum to avoid air leakage in UFAD supply plenum.

DuctSox as fabric duct or sox duct manufacturer in USA has developed a special line called UFSox (Under Floor Sox) for specific application in UFAD system. Underfloor air distribution is frequently used in office buildings, particularly highly-reconfigurable and open plan offices where raised floors are desirable for cable management. UFAD is also common in command centers, IT data centers and Server rooms that have large cooling loads from electronic equipment and requirements for routing power and data cables. The ASHRAE Underfloor Air Distribution Design Guide suggests that any building considering a raised floor for cable distribution should consider UFAD.[5]
Specific space considerations should be taken when using UFAD systems in laboratories because of its critical room pressurization requirements and potential migration of chemicals into the access floor plenum due to spillage. UFAD systems are not recommended in some specific facilities or spaces, such as small non-residential buildings, wet spaces like restrooms and pool areas, kitchens and dining areas and gymnasiums, because UFAD may result in especially difficult or costly in design. UFAD systems may also be used with other HVAC systems, like displacement ventilation, overhead air distribution systems, radiant ceiling or chilled beam systems to get better performance.[5]
