SYNOPSIS

Air-conditioning consumes a large portion of energy in a building. Inefficient in chilled water distribution not only cost more in energy bill, it also compromising the human comfort. Buildings with inefficient chilled water distribution are experiencing balancing issue and uneven cooling which lead to unsatisfied customers and tenants. Excessive pumping from huge centralised pump does not resolve uneven cooling and costing more energy and may also lead to low delta T syndrome.

Accurately controlled cooling systems are crucial to maintain an efficient, comfortable building. Distributed Pumping System, a radically new control strategy for pumping water in a closed loop chilled water circuit of centralised air-conditioning system is proven an intelligent way to a balanced chilled water system. Distributed Pumping Systems replace larger centralised pumps and energy-consuming balancing and control valves with smaller intelligent pumps placed on each floor of the building. This means the system is equipped only with components that generate pressure only when and where needed, automatically balancing the system. The result is substantial energy savings and a more comfortable indoor climate.
