Abdali District Heating and Cooling project

Abdali is Amman’s new downtown district that provides the Jordanian capital with a central business, social and residential destination that the city requires as a regional hub of business and tourism. In Abdali there have been many modern and luxury buildings developed. Towers, residences, business centers and commercial areas have been developed with a total value of more than 5 billion USD. A lot of green areas, parks and a central Boulevard have also been included in the project for the people to get around on foot and enjoy the scenery. This iconic project is projected to be a reference in the Middle East for similar developments not only because of its clean, modern aesthetics, but also because of its sustainability: all the buildings within the complex will be LEED certified. To achieve this certification a lot of measures have been implemented for energy efficiency including a state-of-the-art District Cooling plant.  

What did Abdali need?

The weather in Amman is extreme: really high temperatures during summer and freezing night-time in winter make it difficult to live indoors without heating and air conditioning. District cooling was selected as the most efficient and reliable solution for the chilled and hot water supply of the new development. The total cooling capacity was calculated to be 52,000 TR. Efficiency is a crucial parameter for these kinds of plants, as the amounts of energy consumed throughout the year is very high. Any improvement in efficiency results in huge savings in any developer’s running costs. Amman has an extra handicap: water availability is scarce. A typical 52,000 TR cooling plant’s water consumption is way out of the range that Amman can supply given the conditions of the region. The original design concept would have implemented a grey water supply from the municipality that would be treated in a water treatment plant inside the District Cooling Plant. The problems with this solution were threefold:

  • The capital cost of the water treatment plant
  • The operation and maintenance cost of the plant, mainly due to the extensive chemical treatment required and the cost of the waste management
  • Water treatment plants usually emit undesirable odors which are not compatible with the level of luxury desired for these new developments

ARANER’s solution

In order to avoid the problems of water consumption and a water treatment plant, ARANER proposed a design based on air cooled chillers with zero water consumption. DC Business Case   The benefit of a cooling tower when compared with an air cooled chiller is not that high and may not really compensate for the additional water consumption. This is the case in Amman where the temperature at night decreases drastically and is close to the wet bulb temperature. ARANER’s air cooled chillers are able to achieve almost the same yearly average COP as a system based on cooling towers but with zero water consumption. The high performance results of the final cooling plant with ARANER products have been certified by several international consultants and by the Jordanian Royal Scientific Society.   These incredible results were achieved by implementing three products in which ARANER is a leader.
