Cooling from district and waste heat for businesses - feasibility studies

The topic of solar thermal cooling is one of the core competencies of the ASIC. However, recent case studies for industrial and commercial enterprises including economic feasibility studies revealed payback periods from 8 to 14 years, depending on location and other boundary conditions. The use of existing sources of waste heat to drive a cooling process provides an alternative interesting option.

The waste heat potential survey of the KPC from 2012 reports of more than 6 GWh waste heat from businesses which incur to 97% in communities with an available local or district heating network. Applied to the ever increasing cooling demand in the workplace a large potential for sorption cooling machines locally-operated with local or district heating can be identified.
