Air-conditioning specialists Trane has said that its infrastructure systems installed at the new King Abdullah Financial District in Riyadh will help save huge amounts of energy during operation.

Part of the Ingersoll Rand group of companies, Trane will provide systems for two 50,000 ton cooling plants which are nearing completion at the site and are expected to be commissioned in July or August 2012.

Each plant will feature 16 Trane EarthWise CenTraVac chillers, making the whole operation one of the most environmentally friendly, reliable and energy efficient systems in the Middle East.

“The financial district will require only 80,000 tonnes of the systems’ 100,000 ton capacity. Two massive chilled water thermal storage tanks will be added to optimise the systems’ capabilities.”

“During off-peak periods, (usually at night), the cooling plant will reduce the temperature of these thermal reservoirs, which will be brought online during peak periods, i.e.: when the facility is fully occupied and the heat of the day is at its peak,” explained Albert Haykal, district cooling specialist for the Middle East region for Trane.

He added that the heat rejection component of the system was accomplished by cooling towers, which recycle treated sewage effluent, rather than the more usual air-cooled approach which is less efficient from a power consumption standpoint.

The EarthWise systems used in the King Abdullah Financial District help ensure that the design requirements of the project are met. They feature low-pressure (R123) technology that is intended to nearly eradicate the risk of refrigerant leak.

The systems were also the first and to date, only, industrial chillers to be included on Masdar City’s Future Build product database, a resource for architects, engineers and contractors to use for information on sustainable buildings and systems.
