IEA common study on advanced heat pump systems, technology survey. Part 2: Assessment of systems and conclusions
Abstract This second part describes the advanced heat pump systems which were selected by the 13 participating countries as case studies for the technology and market assessment parts of the International Energy Agency collaborative project. These case studies formed the basis, together with the assessment of research and development trends, described in Part 1 of this paper, for the evaluation of advanced heat pumps for residential heating and cooling. The paper also summarizes the comparison of advanced systems for commercial district heating and industrial applications and contains the main conclusions and recommendations of the technology survey part of the project.
