ROOM COOLING WITH SOLAR THERMAL ENERGY: FASA AG

2018

“FASA AG is considered one of the pioneers of solar construction in Germany. With the construction of a new company headquarters in Chemnitz in 2011, with the ENERGETIKhaus® principle, an active sun office building was developed that almost exclusively (more than 90 %) covers its energy requirements for heating and hot water via the sun. In 2019, the plant technology was extended by a cooling system. When cooling for the summer months, FASA AG chose FAHRENHEIT for the expert in sustainable adsorption cooling from Halle an der Saale.

For the air conditioning of the offices, the heat of the in-house solar thermal system (solar large storage tank with 110 m³ volume) was used, which delivers exactly the right temperature of 80 to 90° C for the operation of the adsorption refrigeration system FAHRENHEIT. Thus, the room is cooled by FAHRENHEIT’s eCoo 2.0 adsorption chiller, using almost no electricity, and being CO2 neutral.“
