Using advance computing methodologies and energy simulations to design unique features in the HVAC system Greg Little Color Rush Jersey , BAKE USA have enabled achieve 35 - 40% less operating cost.
Radiant cooling
Major part of heat exchange from a human body happens through radiation. Hence, any cooling strategy which cools using radiation is the most efficient option for cooling the space. Radiant cooling has been used as a primarily cooling mode for the project.
Chilled water pipes inside slab
Flexible pipes are embedded in the slab which carries chilled water through the slab. All the cold is stored in the slab, which eventually exchanges the cold with the occupants.
Air supply at occupied zone
Air supply for the latent cooling is delivered at floor height. Supply of cool air at the lower level return air at higher level allows most efficient way of air circulation.
VAV boxes & VFD
The office has been divided into different thermal zones. Each zone has an individual VAV box Brian Burns Color Rush Jersey , thereby allowing increasing or decreasing the air flow as per occupancy and load. VFD in the AHU reduces the fan speed accordingly, thus reducing the operational electricity consumption.
Night cooling
Use of radiant cooling inside slab allows chiller to operate at night and store all the cold inside the building structure. This reduces the chiller operation during day. As ambient temperatures are low at night time, higher efficiency is achieved at chiller energy consumption.
Investment & Payback
Though relatively higher priced Black Devin Funchess Jersey , radiant cooling systems give value for money over the long-term by way of significant energy cost savings. Payback is the time taken to recover the additional investment made in the building to make it more energy-efficient.
Advantages of Radiant Cooling
As we all know that heat transfer happens through Conduction, Convection and Radiation. Radiation contributes to more than 67% of heat transfer from a human body. Radiant Cooling or Heating is the most efficient way of heat exchange as it requires no medium. The same advantage is used in radiantly cooled buildings. Surface temperature of wall and roof is reduced. Human body then exchanges heat with that low temperature surface radiantly without requirement of circulating large amounts of air. This reduces energy consumption.
BEKA USA's Radiant Cooling and Radiant Heating by Micro Capillary Tubes (KaRo) takes advantage of this biological fact thus making it the first biologically. Fore More Details Visit More About the Author
Radiant coolingheating affords unheard of living human comfort, free of noise and dust pollution Black Shaq Thompson Jersey , free of air draft and turbulence, no pockets of uneven cooledheated spots, no nose or throat dryness during the heating season Black James Bradberry Jersey , and no 鈥 building syn h 100% fresh air all the time provided by a DOAS (Dedicated Outdoor Air System). Each zone can have a different temperature control if so wanted or needed. For industrial, commercial and residential buildings Black Daeshon Hall Jersey , the radiant heating and cooling installation needs less plenum space and therefore you can get more floors
