Published Papers

A number of papers have been published by participants in the Annex and authors invited by the Operating Agent.

12th IEA Heat Pump Conference in Rotterdam (Netherlands) 2017

A number of papers have been presented at several of the Conference sessions by participant in the Annex and/or people closely related to the Annex work.

At the Conference a special workshop was held on the combination of Heat Pump Water Heaters and Solar Energy and three session blocks of the Conference (1.7 – 1.9) with 21 papers were on the topic of Heat Pump Water Heaters, which can be downloaded as ZIP-file.

13th IEA Heat Pump Conference in Jeju (South Korea) 2021

The latest development and experiences are presented at the ‘hybrid’ conference in on-line sessions. The main bulk of papers, related to HPWH, was on refrigerants, heat exchangers and storage modelling. A number of papers is from participants in the Annex.

Other Conferences

At number of other Conferences papers have been presented by the participants. Conferences organized by Purdue and IIR are typical platforms for presenting heat pumping technologies. But also organisations like EGEC and EHPA have their own venues, not to overlook the Conferences organized by other IEA TCP’s like SHC.

Journals

Scientific and other Journals published a number of papers by participants. Oak Ridge National Laboratory has a number of papers as they manage the R&D Program on HPWH.
