What is TRI-HP?

Watch the video! 

Supercooling method

Commercial ice slurry systems use mechanically scraped-surface heat exchangers, where ice is formed on a cold surface and is then removed by a continuously rotating auger. The scraping process increases the mechanical complexity and adds capital, operation and maintenance costs.
What is needed is a passive concept for ice slurry production that does not rely on moving parts and that has high efficiency such as the supercooling method combined with a flow-based crystallizer used in TRI-HP.
 
The proposed concept works as follows: liquid water at the melting temperature is pumped to the heat exchanger where it undergoes supercooling thanks to the icephobic coatings. Right after the supercooling, the flow is disturbed and forced to nucleate in a controlled manner and location in what is called a crystallizer. After the crystallizer, all supercooling sensible heat is converted into latent energy, and thus solid crystals are formed. Since the ice slurry is not supercooled anymore, it cannot freeze anywhere else, thus avoiding clogging and unwanted nucleation in other parts of the system.

TRI-HP WEB
INAR IN COOPERATION WITH BUILDUP

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. 
Save the date for our webinar that we're organising in cooperation with the BUILD UP portal on Thursday 12 January 2023 from 12:00 to 13:30. We will share the registration link soon on our website and social media.

On Tuesday 24 May  TRI-HP has been presented at the workshop "Trigeneration systems based on heat pumps with natural refrigerants and multiple renewable sources" in the Energy theme of CLIMA 2022 the HVAC World Congress.

This workshop aims to facilitate the dialogue between technology developers and HVAC designer experts to discuss the most prominent barriers and identify country-specific but also EU-wide innovation diffusion pathways, towards full market deployment of innovative, renewable heating and cooling applications.
The workshop was articulated in three different parts: in the first part, TRI-HP partners described the innovations of the developed systems, while in the second part, they answered targeted questions by “the jury” – made up of three HVAC experts from different European countries. The third part of the workshop allowed the audience to ask questions and encouraged them to participate in the discussion.
The project’s innovations regarding trigeneration systems based on heat pumps were presented after which an engaging discussion followed with the jury who commented on the added value of a potential life-cycle analysis of the innovations and discussed the economic gains these systems could bring.

During the last part of the presentation, the focus was more on the policy & social barriers to the uptake of heat pumps, with statements by relevant EU associations (EPEE, EHPA & EEB) who all stated the need for better training for installers organised at EU level. The urgency of addressing the “lack of skills” was illustrated as well during the poll question that was answered by the audience.

TRI-HP presentation at the European Heat Pump Association (EHPA) Research & Innovation Committee Meeting

On June 23, 2022 the TRI-HP project has been presented to the European Heat Pump Association (EHPA) Research & Innovation Committee Meeting. 

The EHPA R&I Commitee aims to establish a diverse and expanding group that can exchange information regarding research, innovation, project calls, initiatives, gaps in technology development and opportunities for advancement. To map HP related R&I at European level and to connect with diverse stakeholders that can offer different perspectives, skills and knowledge.

TRI-HP participation at the 10th annual edition of Sustainable Places #SP2022

The 10th annual edition of Sustainable Places was a hybrid event, from 6th September to 9th September, with the in-person sessions hosted in Nice, France. 
 
TRI-HP was presented in two different workshops:
 
  • RHC Solutions for Buildings and Industry - 3rd Edition (Wednesday, September 7th, 2022):  this workshop brought together a selection of H2020 EU-funded projects involving experts from the biomass, geothermal, solar thermal and heat pump sectors to discuss a common strategy for increasing the use of renewable energy technologies for heating and cooling for buildings and industry. Projects were again invited to pitch their progress and achievements to date. Interactive discussion slots allowed for opportunities to identify possible synergies, cooperation on horizontal issues or potential joint dissemination activities to maximise expected impacts.

  • Low-TRL Renewable Energy Technologies- 2nd Edition (Thursday September 8th, 2022):   this workshop brought together a selection of H2020 EU-funded research & innovation projects dealing with the challenge of researching, developing and demonstrating innovative, efficient, flexible, cost-competitive and environmentally safe technologies, which are still at a low Technological Readiness Level (TRL 3-4). The workshop involved experts on new renewable and low-carbon-emission energy generation and conversion technologies, carbon capture and storage and CO2 re-use technologies, smart energy grid and flexible energy storage technologies.

TRI-HP presentation at the workshop 'Ambition requires action mutual recognition agreements and the upskilling transformation' - European Heat Pump Association

On September 27, 2022, TRI-HP has been presented during the workshop organized by the  European Heat Pump Association entitled Ambition requires action: the sustainable housing revolution with heat pumps.

Expanding the use of heat pumps can play a vital role in the growth of sustainable housing in Europe. This event organized in the context of EHPA’s Heat Pump Forum presented the work and efforts of the H2020 projects, Superhomes2030, Sunhorizon and TRI-HP, and the organization EIT InnoEnergy towards sustainable housing.

During the presentation, the project's coordinator Daniel Carbonell presented the TRI-HP  the tri-generation systems developed during the course of the project, and the main results obtained as well as the technology acceptance study and results.

TRI-HP national Dissemination Workshops- Switzerland, Spain and Germany

In this workshop, the TRI-HP project aimed to bring together expertise from different areas with a focus on more technical discussions on trigeneration systems innovations in order to reach national stakeholders.

Current results from the ongoing project have been presented together with the results of a stakeholder survey in several European countries. The survey provides valuable insights into drivers and barriers of market acceptance of heat pump systems in multi-family buildings.

Three workshops were organized by TRI-HP partners:

You may find the recordings of the presentations in German at this link and in Spanish here.
