A U.S. engineering firm was designing a new district cooling plant for Dubai Healthcare City in the United Arab Emirates. The plant provided 52,000 tons of cooling and the owner, Empower, wanted to provide the chilled water in the most efficient manner possible. The project used a local system integrator for the panel building and installation with EES control system design and chiller plant optimization
The district cooling plant was a new installation with twenty-six 2000 ton chillers. The owner wanted a seamless solution that would utilize the best-in-class hardware along with optimized control for both the electrical usage and water usage. Loss of water in the UAE through the cooling towers is a major cost for the owner so he wanted to run the towers using EES’ chilled water system expertise. The facility consisted of the following:
Characteristics of the new control system:
The new facility was up and running in an efficient manner thereby maximizing the payback through efficient district plant operation. The system calculates the cost of operations and provides diagnostics on the chillers to alert when inefficiencies arise so the operator can turn on other chillers. The load control was paramount to project success. The building heat exchanger control was accompplished through the central plant so chilled water setpoints were optimized based on load. Running a plant of this size in the most efficient manner translated to significant operational cost savings.
