dc.description.abstractSorption cooling technologies are well known as best practice energy efficient cooling supplying apparatus where heat as driving source is delivered by waste heat, trigeneration systems, solar thermal plants, etc. Recent European demonstration projects could not match this prospect due to parasitic electric consumptions. A research project under participation of science and engineer researchers (TU-Berlin, ZAE Bayern) and an energy provider (Vattenfall Europe) was set up to develop high efficient absorption chillers in the range of 50-320 kW. System set ups for the entire cooling generation including reject heat and hydraulic components and control are within the focus. While a 160 kW absorption chiller is on the test bench, 50 kW absorption systems are already running in 2 demonstration plants. The chiller operates in between 25 and 140% of load at thermal COP´s in the range of 0.80 and can stationary deliver cold down to part load of 5%. While driving heat can be used from 55°C up to 110°C at the inlet (standard operation point is at 90/72°C in/out), reject heat inlet temperatures up to 45°C are feasible for normal operation mode. Even higher reject heat temperatures are viable without crystallization, only limited by lower power density. Operation figures of new 50 and 160 kW absorption chillers as well as energy efficiency ratios of demonstration plants are presented. System layout, including market available dry reject heat systems, gains parasitic electric EER values lower than 6% of cooling load. New volumetric/energetic density benchmarks up to 23 l/kW are proven. Results of 50 kW absorption system overreached thermodynamical targets while proposing a lower price than market available. System demonstration and development up to 320 kW cooling load systems are actually undertaken in Lab and will be lead to real estate installations in 2013.en
