AN EFFICIENT EVOLUTION OF HVAC SYSTEMS DISTRIBUTED PUMPING ENABLES HIGH-PERFORMANCE BUILDINGS Accurately controlled cooling systems are crucial to maintaining an efficient, comfortable building. But this accuracy can be difficult to achieve with standard valve-based chilled water systems. These systems face challenges with balancing and poor dynamic flow regulation, which leads to severe energy loss, inadequate climate control and uncomfortable occupants. Distributed Pumping from Grundfos means a more: Balanced Solution So why are building owners and operators turning to more intelligent ways to balance their HVAC systems. • Improved system design • Improved indoor climate • Up to 54% energy savings Distributed Pumping Solutions replaces centralized pumps, balancing valves and control valves with smaller more intelligent pumps throughout the building. This means the system is equipped with the components that generate pressure only when and where it’s needed, automatically balancing the system and reducing your energy consumption. Sustainable HVAC System Your HVAC system is made up of many components, all working together to provide building comfort. Traditionally, pumps role in this was to circulate water — all of it, at a set rate, without any understanding of what was happening in the system. Now, by placing pumps out in the system you can deliver the precise amount of fluid needed to achieve ideal indoor climates without wasted energy. That’s why Distributed Pumping Solutions are the most efficient solution for your new or existing building — IT’S YOUR INSURANCE AGAINST BUILDING DRIFT. SUBSTANTIAL ENERGY SAVINGS ACHIEVED WITH DISTRIBUTED PUMPING These figures are based on a mixed-use building in Singapore. (See case study on page 6.)
