Technology 

The AC-Sun unit is driven by high-efficiency turbines which use no electrical energy. The turbines are powered by steam, generated by thermal solar panels or other heat sources such as waste heat or district heating. The process can be powered by heat source providing temperature of 60oC or higher. 

The cooling system also creates waste heat that is transferred outside the building. This waste heat can be used for other purposes e.g. heating up a swimming pool.
