GeneralSolar termal heating anc cooling technology was utilized in the 2008 Olympic Summer Games. Two separate systems supplied the Olympic sailing center in Qingdao with solar energy. The logistics center was equipped with a solar system for solar cooling, heating of warm water and supplying of energy to the heating system. Operations of the unit, encompassing a collector area of 638 m² /6,867ft², had already begun in 2006.Concurrently, 666 m²/7,169 ft² of collectors for heating the swimming pool, heating of warm water and supplying energy to the heating system, was installed in the Sports Center. The unit on top of the Sports Center captures everyone’s eye owing to its breathtaking architectural design.
TechnologyThe energy generated from a collector area encompassing 638 m²/6,867 ft² on top of the Logistics Center is fed to a buffer store, which holds a capacity of 12 m³/3,170 galUS. Two absorption cooling units are powered by this energy stored in the buffer store. Furthermore, the energy is used for the heating of warm water and, in case heating is required, to supply energy to the heating system. The facility is coupled to a district heating supply to care for peak loads. After feeding the solar energy of the SportsCenter (with a collector area of 666 m² /7,169 ft²) to two buffer stores, which have a capacity of 7m³/1,849 galUS each, the energy isprovided for heating the swimming pool, heating of warm water and to supply energy for the heating system.
