Facility Description:
Have you ever been surfing on eBay, looking for something interesting? How about sending or receiving money using PayPal? Bought tickets using StubHub? These are all functions that the eBay Utah Data Center server is performing to this very day. And that isn’t even the most interesting thing about this data center. The eBay Utah data center in particular is not powered like most other data centers; it is the world’s first to use Bloom Energy Savers™ as the main power source rather than the main electricity grid. Ebay’s data center is also not cooled like most other data centers. Instead of pushing cold air from underneath a raised floor through perforated tiles, IT equipment at the site is cooled directly by plate heat exchangers bolted onto the back of the racks. Furthermore, instead of using industrial chillers, the facility pulls air from the outside into cooling towers which are supplemented by an evaporative cooling system. The innovative facility has one more interesting feature. It is supplied by Griswold Controls’ Pressure Independent MVP valves. MVP Valves offer pressure independent control with an actuated valve. They are available in 2-1/2″ to 10″ size and flows from 40 GPM to 1220 GPM.
Project Description:
These Pressure Independent MVP valves help reduce energy costs and increase occupant comfort. Traditional control valves allow for overflow and underflow to coils which means excess water is pumped to compensate for their inaccuracy. The actuators in traditional valves also have to cycle more often to compensate for pressure changes in the system that impact the flow. By precisely controlling the flow of water to each coil, the valve enables energy savings, increases available plant capacity, minimizes capital expenses necessary to acquire additional capacity, and simplifies system design and control.
