Application of a Novel, Vacuum-insulated Solar Collector for Heating and Cooling

A solar collector field of 250 m2 is being set up for cooling and adding to the heating of a building of 4000 m2 with mixed use, which includes offices, laboratories, computing and electronics facilities, and a public area. Novel solar thermal collectors will be used, which reach excellent performances, thanks to vacuum-insulation and innovative assembly techniques. This allows the efficient operation of an absorption cooling unit. The thermal concept combines the warm and cold streams and gives priority to solar energy.
