Urban redevelopment plays a major role in the growth strategy of today's cities. The advantages of urban renewal are obvious: substantial savings can be achieved by using modernized, energy-efficient infrastructure, including air conditioning and cooling facilities - which draw a significant fraction of energy in modern urban areas. In terms of land area, HafenCity is considered the most significant urban redevelopment project in Europe - at the former Hamburg port district.
The heaviest energy users in the cities and urban areas are HVAC systems with their accounts of about one third to half of the overall power consumption - however, recent advanced HVAC technologies promising tremendous energy-saving potential and, in addition, essential environmental benefits. Oilless compressors, variable speed drives, free cooling, microchannel heat exchangers, heat recovery and eco-friendly refrigerants - all these are crucial elements of modern HVAC infrastructure found in Kaltra equipment and offered for Elbbrucken district of HafenCity.
The scope of offered equipment includes Turbocor-based water-cooled chillers with evaporatively cooled heat rejection units for comfort air conditioning, redundant precision air conditioners for mission-critical facilities, and free cooling economization loops. The total duty of the plant exceeds 10MW cooling and 4MW heating.
