Trigeneration systems based on heat pumps with natural refrigerants and multiple renewable sources
TRI-HP will provide the most appropriate knowledge and technical solutions in order to cope with stakeholder’s needs, building demand characteristics, local regulations and social barriers.
Objectives
- Development and testing of affordable flexible tri-generation systems able to cover heating, cooling and electricity demands with a large share of renewable sources. The systems developed are:
- Solar-ice system using a supercooling ice-slurry heat pump with solar as main heat source
- Dual source/sink heat pump system using ground and air as heat sources/sinks
- Development and testing of special heat exchangers for the different heat sources and refrigerants, able to improve the performance of the heat pumps. Three heat exchanger types will be developed:
- An always free-of-ice evaporator, the so-called supercooler, for an ice-slurry heat pump
- Tri-partite gas cooler for simultaneous domestic hot water and space heating provision for a CO2 heat pump
- A dual source/sink heat exchanger for ground/air renewable heat sources.
- Development and testing of three natural-refrigerant based reversible heat pumps able to provide heating and cooling with multiple heat renewable sources. Three heat pumps will be developed:
- A transcritical CO2 heat pump with a tri-partite gas cooler and a supercooler evaporator
- A propane heat pump with a dual source/sink heat exchanger for dual ground/air use
- A propane heat pump with a supercooler evaporator
- Development of two advanced controls:
- A heat pump self-diagnosis algorithm to increase reliability and facilitate maintenance
- An advanced energy management system based on model predictive control
- Understanding and improving stakeholders’ acceptance of TRI-HP systems
- Analyse and identify the interest and needs of end-users and installers
- Understand and determine other stakeholder’s acceptance
