There are 24 results.
IEA HPT Annex 49: Design and integration of heat pumps for nZEB
A dominating concept to reach a nearly Zero Energy Building (nZEB) is the combination of solar PV systems and heat pumps. The extended scope of the Annex 49 regards the balance of single buildings and groups of buildings/neighbourhoods, a thorough investigation of heat pump integration options for nZEBs and nZE neighbourhoods by means of monitoring and simulation as well as the design and control optimization for heat pumps in nZEB and the integration into energy systems.
IEA HPP Annex 47: Heat Pumps in District Heating and Cooling Systems
A significant use of alternative heat sources with the help of district heating and cooling networks is a major challenge for a sustainable energy supply. In times of increasing shares of fluctuating producers such as PV and wind energy, the relevance of heat pumps increases. Within the framework of the IEA HPT Annex 47, potentials and barriers for the integration of heat pumps in DHC networks were analyzed.
IEA HPT Annex 50: Heat Pumps in Multi-Family Buildings for Space Heating and DHW
The project aims at demonstrating the potentials of heat pump technology for the energy supply of multi-family houses (MFH) and to contribute to the elimination of existing market barriers. Concepts and innovative technology options for heat pumps in MFH will be investigated in detail by means of simulations and experiments. The findings and results will be presented in international expert meetings and disseminated among national heat pump manufacturers, installers and planners.
IEA HPP Annex 33: Compact heat exchangers for heat pumping equipment
International cooperation aiming at widening the use of compact heat exchangers in heat pumping equipment. The goal of this project is to identify compact heat exchangers, either existing or under development, that may be applied in heat pumping equipment such as compression or absorption heat pumps.
