IEA HPT Annex 43: Fuel Driven Sorption Heat Pumps

The project aimed at investigating the performance and market potential of gas-fired absorption heat pumps (AHPs) in domestic and small commercial or industrial buildings or applications. Selected processes were simulated for various types of buildings in order to calculate the energetic, ecological and economical potential of this technology. The results were compared with monitoring data of a gas-fired AHP system. In addition, a market survey including market barriers for gas-fired AHPs in Austria was conducted and a list of market supporting measures was compiled.
