Pleasant temperatures in the middle of the desert

The highest number of skyscrapers over 300 m high, the third largest airport by passenger volume, the ninth largest port by container throughput and 19th place in the ranking of the most important financial centres worldwide - Dubai surprises both architecturally and economically. The capital of the emirate of the same name, with its 3 million inhabitants, welcomes 15,3 million visitors annually and has been welcoming culture enthusiasts since 2016 with a world-class multifunctional cultural centre, the Dubai Opera.

Designed by Danish architect Janus Rostok (Atkins) and modelled on the shape of a traditional Arab sailing ship (dhow), Dubai Opera offers 2.000 seats for a concert, 1,000 seats for a gala dinner, up to 2,000 m² of space for events and trade fairs, and an impressive rooftop restaurant including a “Sky Garden” with views of Burj Khalifa and the Dubai fountains.

Those who visit Dubai Opera enjoy culture, architecture and a view - perfectly air-conditioned, even when it is 40 °C or more outside. Not least thanks to the intelligent Oventrop systems.

Precise cooling with Oventrop valve systems

Oventrop HydroControl VTR and VFC double regulating and commissioning valves as well as differential pressure and flow regulators regulate the flow and pressure in the complex, extensive cooling circuits. Even during load changes and in partial load operation, they provide the prerequisite that all rooms are cooled precisely and evenly. By using the Oventrop HydroControl VTR and VFC double regulating and commissioning valves and the differential pressure and flow regulators, the individual risers are supplied as required. Increased mass flows in the connected consumers are avoided by reducing excess differential pressure in the differential pressure regulators. The desired flow rate can be precisely controlled and adjusted - each consumer in the cooling circuit is supplied equally.

The importance of a degree-acurate function is shown by the effect of incorrect flow rates in the respective risers on energy consumption. If the flow rates are not correct, the unfavourably located consumers are only supplied sufficiently if the favourably located consumers are oversupplied and cooled by approximately 1 °C too much, which increases the energy costs by a significant 15%.

Furthermore, Oventrop gate valves, stainers, ball valves, swing check valves and butterfly valves are used in various areas.
