VRF / VRV systems in Abu Dhabi City 

VRF / VRV systems in Abu Dhabi City: local context

Abu Dhabi City covers the main island's grid of streets, from the Corniche towers and government buildings to dense mid-rise blocks built from the 1980s onward, along with hotels, hospitals and private palaces. Many buildings are now 20–40 years old, so replacement and upgrade work runs alongside new towers. Manolia's work in the capital includes building works for a G+3P+24 office tower, MEP works for a 28-storey tower and HVAC works for Al Bahar Palace.

• Fire and life safety upgrades are approved and witnessed by ADCDA, and refurbishments commonly bring smoke control, alarm and sprinkler systems into line with the current UAE Fire & Life Safety Code.
• Palaces demand concealed, quiet HVAC with precise zoning, robust standby capacity and finishes that tolerate no visible ductwork or grilles out of place.
• ADDC load approvals and substation arrangements need to be confirmed before final electrical design, especially when existing buildings add significant cooling load.

Building types we serve in Abu Dhabi City

For office buildings, the work concentrates on VAV or FCU zoning for flexible floor plates, tenant fit-out interfaces, energy metering and BMS integration.

Scope of work

• Brazing under nitrogen purge to prevent internal oxidation, followed by pressure testing and deep vacuum before charging.
• Fresh-air provision through dedicated fresh-air units or treated air connections, since VRF indoor units alone do not dehumidify outdoor air well.
• Refrigerant charge calculation and recording, followed by manufacturer commissioning and test run of every indoor unit.
• Refrigerant leak risk review for small rooms such as bedrooms and offices, checking the charge per system against room volume and specifying leak detection where needed.

Systems we install

• Ducted, cassette and high-wall indoor units
• Central touch controllers and BMS gateways

UAE site and climate challenges

• Fine dust settles on outdoor coils within weeks during construction or sandstorms, so access for coil washing is planned and units are protected until handover.
• Outdoor units mounted on facade ledges or balconies in high-rise apartments can recirculate hot air in confined recesses, so recess depth, louvre free area and discharge direction are checked with the manufacturer before installation.
• VRF versus chilled water: VRF avoids a plant room and suits villas and low-rise buildings, while chilled water generally suits larger towers and has longer equipment lives.
