Webinar - Novel heat pump technologies based on natural refrigerants and multiple renewable sources

Share this Post:

The next 12th January 2023, the TRI-HP project organises its webinar entitled "Novel heat pump technologies based on natural refrigerants and multiple renewable sources". The session will be hosted by BUILD UP.


For the energy transition to succeed, heating & cooling in buildings need efficient, clean and affordable systems. With this in mind, the TRI-HP project has developed trigeneration systems that provide heating, cooling & electricity that:


  • Are based on heat pumps with natural refrigerants;
  • Have a high degree of demand-side flexibility
  • Reduce both capital and operational costs
  • Integrate a high degree of on-site renewables.

Three heat pump systems have been tested within the project: two solar-ice slurry systems based on natural refrigerants with intermediate storage, and a dual/source sink system using a reversible propane heat pump to provide both heating and cooling.


The systems are backed up by Advanced Energy Management Control which allows for optimal real-time management of energy flows that can lead up to 15 to 20% energy savings when the heat pumps are connected to the smart grid.
