Chiller installation in Khalifa City 

Chiller installation in Khalifa City: local context

Khalifa City is a suburban district on the mainland between Abu Dhabi airport and Yas Island, made up of large villa plots, private palaces, schools, mosques and neighbourhood retail, with mid-rise apartment buildings in some sectors. It has grown steadily since the 2000s as a family area. Manolia completed the MEP works for a school project here.

• Schools need fresh-air AHUs with energy recovery and dehumidification, CO2-based ventilation control, and fire alarm and public address systems integrated for safe evacuation.
• Inland mainland sites bring dust and high summer temperatures, so plant is derated and air intakes protected with sand-trap louvres and good filtration.
• Estidama Pearl requirements apply to new buildings, with government schools typically targeting a higher rating.

Building types we serve in Khalifa City

For malls and retail centres, the work concentrates on large-volume air handling, tenant-ready chilled water or refrigerant capacity, smoke extraction for atriums and car parks and food-court exhaust.

Scope of work

• Review of plant capacity, redundancy and part-load profile so the number and size of chillers matches how the building actually operates through the year.
• Structural and acoustic coordination for roof or plant-room locations, including spring isolators, inertia bases and maintenance clearances around each machine.
• Header, bypass and expansion arrangements with air separators, chemical dosing pots and make-up water connections.
• Power cabling, starter panels and interlocks from the LV board, coordinated with the electrical contractor and utility load approval.

Systems we install

• Air-cooled screw or scroll chillers selected for high ambient
• Refrigerant leak detectors and plant-room emergency ventilation fans

UAE site and climate challenges

• Hot discharge air recirculating between closely spaced roof chillers raises inlet temperatures further, so layout, screen walls and spacing are checked against manufacturer clearance guidance.
• Water-cooled plants with cooling towers face high water consumption and Legionella risk in warm basins, so dosing, drift eliminators and treated or TSE make-up water are considered at design stage.
• Air-cooled versus water-cooled: air-cooled needs no cooling tower or water treatment and suits most towers, while water-cooled is more efficient but needs make-up water, treatment and more maintenance.
