AAON rooftop units were selected for the camp area belonging to LUCOIL in the West Qurna region of Iraq. The AAON RN series rooftop units are used for climatic conditioning and pressurization of E-Houses, which are integrated into the camp’s electrical system and manufactured by SIEMENS in Turkey. These units can operate non-stop in regional conditions, reaching temperatures of up to 55°C.
After successfully passing tests conducted in Sakarya, the RN-031 model units were disassembled and shipped to be integrated into the E-House system at the construction site. In the E-House testing and commissioning process, the AAON rooftop units were successfully operated, with the project supported by Atlantik Grup. The units, which operate in a redundant manner, are connected to a special damper system.
The units operating in the West Qurna Phase 2 project, specifically in the Well Pad 11/1A camp, meet the pressurization needs of the E-Houses, ensuring that dust does not enter the system. The variable speed compressors and variable speed fans of the units fulfill this function. The AAON RN series units, equipped with digital scroll compressors, can adjust the airflow by up to 30% and the refrigerant flow by up to 10%. This capability helps adjust the discharge temperature, preventing issues like condensation and dripping from vents.
Under the challenging regional conditions, the AAON RN series units can increase the fresh air supply to 100% when needed, maintaining a positive local pressure inside the E-Houses, and fully meeting the climatic conditioning and pressurization requirements requested by SIEMENS.
The units, integrated into the building automation system, fully meet the cooling load requirements in the E-House and, thanks to the digital scroll compressors, also operate efficiently during transitional seasons, ensuring energy efficiency. The RN series rooftop units, which work with dual fans, regulate the fresh air intake by operating the supply and exhaust fans sequentially, adjusting the local pressure and preventing dust or other particles from entering the E-House under harsh desert conditions.
