SunHorizon @Green heating and cooling workshop: Heat Pump RD&I in EU Projects

SunHorizon @Green heating and cooling workshop: Heat Pump RD&I in EU Projects 150 150 SunHorizon Project

This event is organised in the framework of the REWARDHeat project, as an opportunity to gather with heat pump stakeholders and share knowledge about the heat pump role in the selected EU projects. 

REWARDHeat project is the organizer and aims to demonstrate a new generation of low-temperature district heating and cooling networks, which will be able to recover renewable and waste heat, available at low temperature. These networks will be able to increase production and distribution efficiency by recovering, renewable and waste heat available at low temperature.

The other two EU projects (SunHorizon and ETIP-RHC) are invited to present their perspective and approach in R&I about heat pump application.

The European Technology Platform on Renewable Heating and Cooling (RHC-Platform) brings together stakeholders from the biomass, geothermal, solar thermal and heat pump sectors to define a common strategy for increasing the use of renewable energy technologies for heating and cooling.

Meanwhile, SunHorizon aims at deploying sun-coupled innovative heat pump in the residential and tertiary sector, thus supporting the decarbonisation of the heating and cooling sector.

Join us in this event to know more about the projects’ development and how innovative heat pumps are deployed in different sectors. 

This event will take place on October 6th and it’s a free virtual event. In your registration, you can select the virtual ticket.

Updates from the tests developed in CEA INES’ facility

Updates from the tests developed in CEA INES’ facility 579 326 SunHorizon Project

In the first half of 2021, CEA experimental platform at INES is hosting the tests of three solar-based hybrid technologies developed by SunHorizon industry partners before the in-situ deployment phase during summer 2021: TP2, TP4 and high vacuum flat solar thermal panels.

Figure 1 TP2 system test principles and outlook of real hardware integration during installation

The test of TP2 involves Ratiotherm (solar heat distribution and 1.3 m3 stratified thermal storage, controller with electricity self-consumption strategy) and Boostheat (20kW thermal compression gas-fired C02 heat pump) as real hardware components while 50m² Dualsun solar PVT panels are virtually emulated, as well as the building and user heat and electricity demand. The TP2 installation in CEA INES semi-virtual lab is finished. A custom 9-days test sequence was developed by CEA to assess TP2 performance, mainly regarding gas and electricity consumptions, in representative operating conditions all year round, for residential heating and DHW application like the Riga Sunisi demo site in Latvia. The test setup already allows gaining experience for fail-proof connections and wiring recommendations of Ratiotherm and Boostheat altogether and validating the proper operation of controllers. The performance test results target is to consume 9MWh of gas and 5.5MWh of electricity concerning 1.5 MWh as DHW, 12.2MWh as space heating and 7.7 MWh as electricity demand.

Figure 2 : TP4-BDR system test principles and real hardware running in semi-virtual test bench

The semi-virtual lab test of TP4 from BDR for residential heating, cooling and DHW application was performed in March-April, in T3.3, following a custom 8-days test sequence developed by CEA for Piera demo site in Spain. BDR developed TP4 new concept for maximising the overall system emissions savings and the PV electricity self-consumption through BDR 6kW reversible air source heat pump and 440L water storage, 4m² thermal and 10m² PV flat solar panels (virtually emulated) with homogeneous tilted roof integration. The analysis of the results is under work, it is already demonstrating 50% annual primary energy savings and 44% renewable energy ratio of the real controller and hardware, very close to the estimated values by dynamic TRNSYS simulation.


Figure 3 : outlook of the LTpower panels shipment and outdoor solar thermal performance test principles

The Sunhorizon demo pilots of TP3 in Sant Cugat, TP1 in Verviers and Berlin are relying on TVP solar LT power high vacuum flat solar thermal panels. Before being demonstrated also in INES PFE professional training platform in summer 2021, CEA is installing 8m² LT power panels on its sun-tracking outdoor solar test bench to get a preliminary experimental performance assessment. Tests are running for a few days in June with appropriate weather conditions, in Chambéry, France. The resulting LTpower performance test datasets and numerical model are to be used in the forthcoming TP1 semi-virtual test or further TVP solar sizing tools and performance simulations.

SUNHORIZON TECHNOLOGY DEPLOYMENT APPROACHING IN RIGA DEMO

SUNHORIZON TECHNOLOGY DEPLOYMENT APPROACHING IN RIGA DEMO 1024 649 SunHorizon Project

During the last months, SunHorizon partners have been actively engaged in various preparatory works for deployment of SunHorizon technologies in Riga demo site, which is located in Latvia and managed by Riga Technical University (RTU). The demonstration will take place in two single-family residential houses where TP2 is going to be installed. It comprises a heat pump from Boostheat, PVT panels from DualSun along with a stratified storage tank, solar station, smart electric heater and other components from Ratiotherm, coupled in an integrated technology package to provide the household with space heating, domestic hot water as well as PV-produced electricity.

Integration of the various technologies in a single SunHorizon TP2 is made possible thanks to the strong collaboration of the technology providers and other partners involved in detailed thermal modelling of the buildings and simulation of the TP2 operation at the specific sites considering their energy consumption patterns and weather conditions throughout the year. While the technical diagrams and simulations were prepared by the SunHorizon partners, it is now up to the local installers to deploy the technologies in both houses. The installers were selected by RTU in an open tender and will complete their work in early autumn before the next heating season. To achieve this, the technology providers are about to start manufacturing the components to be delivered to the demo site during the summer months.

After commissioning of the SunHorizon technology package, its operation will be continuously monitored with a number of heat and electricity meters and room sensors. In addition to that, a weather station has also been installed in Riga. These data will be available for the project partners on the cloud close to real-time in order to keep track on the previously-defined KPIs and assess the energy and cost savings brought by SunHorizon.

We present you the SunHorizon App

We present you the SunHorizon App 1024 446 SunHorizon Project

The SunHorizon app developed by CheckWatt, allows the user to view real-time information about their building’s indoor climate and energy consumption. Furthermore the user can provide feedback about their perceived comfort levels (e.g., if a room feels too hot/cold). The feedback provided is then used by the self-learning algorithm, that effectively ensures a comfortable indoor climate with the lowest energy consumption possible. The app will be available for both Android and IOS platforms. 

Since the demo sites can either be private residential buildings or public buildings the app will be used differently. Users of a residential building will download the app on their personal phones and create an account to access building information and functions. Users tied to public buildings will either be personnel working in the building or possibly visitors. 

To get started with the app the user needs to perform two steps. The first step is to download the app from Google play or App Store and register to create an account. The second step is to connect their account to their building using a code that would have been given to the user in advance. 

Once the user has completed the two initial steps they are ready to explore the app and its functions. For instance, they can view the current indoor temperature of a room. Analyse their energy consumption this month or provide feedback about a room feeling too hot and humid. 

Insights from the demo site in Madrid

Insights from the demo site in Madrid 652 408 SunHorizon Project

Madrid demo site is a social housing building located in central Madrid in Tres Peces street. The building, built in 1948, was originally a police station and dungeons consisting of just one floor above ground. In the middle of the 20th century, it was refurbished achieving the configuration that currently exists with nine apartments, distributed on five floors.

In 2017, an unfavorable Technical Building Inspection report was carried out requiring immediate reparation of several technical aspects. For this reason the EMVS promoted a retrofitting project consisting mainly in improving the envelope (insulation, facade, windows, roof), the structure and the accessibility (ground floor, elevator, etc.)

In 2018, the building was selected as a Demonstrator for the SUNHORIZON European Project. The intervention would warrantee the renovation of the HVAC systems, which go from being individual to centralized, and the integration of renewal energy systems.

The objective would be to contribute to the technological development that allows a more efficient management of energy to supply space heating and cooling and domestic hot water through the coupling and optimization of innovative solutions of heat pumps with advanced solar collection technologies.

The technology package selected for Madrid demo site was TP4:

Due to the implementation  of two retrofitting projects, one focused on the passive elements, and the other focused on the HVAC systems (SunHorizon) of the building, both with different execution plans and in order to maximize the efficiency of the works and minimize the impact on the neighbours, the execution of the SunHorizon intervention was split into two phases:

The first phase, which included both the installation of the Climate, DHW and Ventilation equipment inside the dwellings, as well as the hydraulic vertical distribution. It was carried out in parallel to the Passive renovation. The works began in June 2019 and ended in March 2021.

And the second phase, which included the installation of the SunHorizon equipment, solar field, hydraulic, electrical and control system and commissioning.

At the present time, the tender procedure to select the main contractor to execute the second phase of the SunHorizon project has been finalized, and the shipment of the equipment to the demo is being organized with the technical partners of the project. The start of the works is planned for the beginning of July with expected completion at the end of September, when it is foreseen the beginning of the energy service supply and the collection and analysis of the data.
