Innovation in residential heat pumps with natural refrigerants

Heat pumps are a key technology for the electrification of thermal demand. One of the challenges they face is the transition towards refrigerants with low GWP (Global Warming Potential)

Programme

• A series of innovative developments in heat pumps for the residential sector will be presented: heat pumps that use natural refrigerants, such as CO₂ (R744) and Propane (R290).
• Their integration in trigeneration systems associated with a range of renewable energy sources will be discussed.
• The event will address questions such as:
  • Is it possible to design a dual heat pump capable of exchanging heat with glycol water from geothermal probes or directly with air or with both simultaneously?
  • Is it possible to design a dual CO₂ heat pump with good performance, not only in DHW, but also in heating + DHW mode?
• This event also aims to identify opportunities associated with this type of innovations. To do so, group dynamics will be used in order to contrast the needs of manufacturers and installers in the current situation brought about by the impact of F-Gas.

Further information

The developments indicated have been carried out within the framework of the “Trigeneration systems based on heat pumps with natural refrigerants and multiple renewable sources (TRI-HP)” European project, aimed at significantly reducing the demand for primary energy, as well as greenhouse gas emissions, in comparison with conventional systems.
