Germany-based Engie Refrigeration has been awarded a contract to supply chillers for Terminal 2 of Moscow’s Domodedovo Airport, three years after the company won a similar contract for Terminal 1.

Domodedovo Airport is fast becoming Russia’s important aviation hub and is Moscow’s largest airport with more than 33 million air passengers a year.

According to Engie, as with the previous project for Terminal 1, the new contract is to provide chilled water for air conditioning the arrival and departure areas and the administration building. Additionally, it will provide cooling for the server rooms.

The full order, Engie said, comprises chillers to provide an overall refrigeration capacity of 45MW. It will involve models from Engie’s water-cooled Quantum X series – in some cases, with twin–tubed condensers for heat recovery for service water pre-heating – and air-cooled machines from the Quantum A series, Engie added.

All Quantum chillers are fitted with oil-free turbo compressors. The order also includes Pensum reversible water chillers, Engie said.

According to Engie, the entire refrigeration system for terminals 1 and 2 is operated and monitored by

the system manager, a control and monitoring software from Engie Refrigeration. The operation, the company said, enables free cooling to be coupled with normal cooling systems. As a result, it added, it is possible to considerably raise the EER value and, particularly in part load operation, the ESEER value, at the airport for most of the year.
