Month 36: Ready for commissioning.

 Month 36: Ready for commissioning. 150 150 SunHorizon Project

Report from our 2nd review meeting with the European Commission.

Month 36 is critical in most H2020 projects; it’s usually the month by which things start to go “live”, solutions that took years to develop reach the first customers (or end-users, or demo sites, as we usually call them) and the Consortium have to face many unforeseen events. SunHorizon hasn’t been any different.

We started with great promises: creating 4 technology packages with 6 different technological components and commissioning them in 8 demo sites in 4 different EU countries, by September 2021.
Despite COVID-19 and consequent suppliers’ bankruptcy, raw material scarcity, certification requirements, and overloads of the logistic chain, we have managed to ship all the technologies to 3 of our 8 demo sites by September 2021. This is one of our Consortium’s greatest achievements.

Unfortunately, the work at the sites just starts from this point: little parts to be replaced, sensors which do not fit the requirements, missing devices, unstable internet connections. This is complete fieldwork, which our Consortium partners have dealt with incredibly. RTU (Riga Sunisi and Riga Imanta residential houses), VEOLIA (Sant Cugat “Mirasol Civic Centre”), EMVS (Madrid “Tres Peces 9”) will be able to commission their site in January next year!

For the others, just a few more months of hard work and site work…keep updated to know more!

FAHRENHEIT´S HYBRID CHILLER UNDERGOES PERFORMANCE TESTS AND OPTIMISATION OF OPERATION STRATEGY

 FAHRENHEIT´S HYBRID CHILLER UNDERGOES PERFORMANCE TESTS AND OPTIMISATION OF OPERATION STRATEGY 150 150 SunHorizon Project

Over the last months the hybrid chiller unit ZEO M 10 HCN 30 developed by Fahrenheit GmbH has undergone intensive testing and improvements. The chiller unit is the “little sister” of the hybrid chiller ZEO M20 HCN 60 that will be commissioned beginning of next year in Sunhorizon’s demosite in San Cugat (Spain): its cooling power has been reduced by 50% to meet the power and space requirements of the laboratory environment of CNR ITAE in Messina (Italy) and Fraunhofer Institute of Solar Energy Systems ISE in Freiburg (Germany).

The combination of adsorption and compression chiller technology within one single machine offers a higher flexibility and broadens the range of operation both for lower chilled water temperature and higher ambient temperature. Whereas the hybrid chiller has been tested according to existing standards for different part load conditions with the re-cooling unit placed in a climatic chamber, the main focus of the experiments at CNR-ITAE was on the operation and control strategy in bivalent mode (adsorption and compression working in parallel).

Apart from the experimental results a valuable outcome was to gain experience in the transport, installation, and commissioning of the newly developed hybrid chiller and to have first users outside Fahrenheit to operate the machine.

The re-cooler was placed in a climatic chamber to simulate different ambient temperatures. The measurements are carried out based on EN 14511:2018 and EN 14825:2018 for Hybrid Chillers.

The measurements were performed by simulating cooling load thanks to properly controlled external circuits. The full hybrid mode was validated with a specific focus on the optimization of the management strategy, to maximise the achievable savings during real operation in the demo site.

“SUN COUPLED HEAT PUMPS NOW READY TO SUPPLY THE SUNHORIZON DEMO SITES” press release

 “SUN COUPLED HEAT PUMPS NOW READY TO SUPPLY THE SUNHORIZON DEMO SITES” press release 150 150 SunHorizon Project

SUNHORIZON PRESS RELEASE – December 2021

Brussels, 06.12.2021.

SunHorizon is an EU funded project[1] which aims to demonstrate up to TRL 7 innovative and reliable heat pump solutions (thermal compression, adsorption, reversible) able to provide heating and cooling to residential and tertiary buildings with lower emissions, energy bills and fossil fuel dependency when coupled and managed with advanced solar panels (PV, hybrid, thermal).

The project is currently on its 38th month of activity, and the work on the demo sites is progressing; three of the eight demo sites are finalizing the commissioning stage and are ready to supply the residential and tertiary buildings!

The coldest location selected for the demonstration of SunHorizon technologies is Riga (Latvia), where two single-family residential houses have been upgraded with a heat pump coupled with photovoltaic thermal collectors (PVT) and stratified thermal storage. Integrated and efficient operation of the whole SunHorizon technology package #2 (TP2) is enabled by advanced control solutions developed within the project, and end-users’ feedback during the demonstration is acquired through a dedicated mobile app.

The gas-driven thermal compression heat pump replaces the existing gas boiler to provide space heating and domestic hot water in a much more efficient way. The outside air and heat produced by the PVT panels serve as additional heat sources to the heat pump. When there is no immediate heat demand, the thermal energy provided by the PVT field is stored in a stratified thermal storage tank, whereas the electricity produced by the solar panels fully covers the electricity demand of the household during the year (employing net metering). Additionally, TP2 includes a smart electric heater enabling power-to-heat conversion for the surplus electricity from the PVT field.

“Demonstration of the innovative SunHorizon technology package in Latvia is going to provide broad experience for the local stakeholders considering that gas-driven heat pumps, stratified energy storage and PVT panels haven’t been used much in our country so far,” explained Zane Broka (Riga Technical University). “Whilst replacing their existing gas boiler, the households will be able to continue benefiting from their already existing gas grid infrastructure, meanwhile significantly increasing the operating efficiency of their heating system. Also, thanks to the onsite electricity generation, their overall energy cost is going to decrease. The flexibility and efficiency of the new SunHorizon system is further enhanced by the thermal storage and power-to-heat solutions.”

The deployment of SunHorizon TP2 in Latvia is managed by Riga Technical University. The technologies installed are provided by SunHorizon partners: Boostheat, DualSun, Ratiotherm and Schneider Electric. In addition, the demonstration strongly relies also on the modelling efforts and cloud solutions provided by Cartif, CheckWatt, IES and RINA-C.

The installation of the main TP2 components in both demo sites was completed by November 2021. The commissioning is scheduled for December 2021 (Imanta site) and January 2022 (Sunisi site).

Another location selected for the demonstration of the SunHorizon technologies is a social housing building built in 1948 in Madrid (Spain), which originally served as a police station, then was retrofitted and converted into 10 apartments (1072 m2). The installation of SunHorizon technology package #4 (TP4) has been concluded and the commissioning phase is going to start soon.

The SunHorizon contribution to the building comprehends a full renovation of the HVAC system by installing two heat pumps (one air-to-water and one water-to-water) coupled with hybrid solar panels and stratified storage tanks to supply the demand for space heating and cooling (SHC) and domestic hot water system (DHW).

Moreover, inside the dwellings, the SHC and ventilation are integrated into the same all air system, zoned per room by means of a fan-coil with plenum and a heat recovery unit. On the other hand, DHW production is produced instantaneously through an individual heat exchanger.  

The system is centralized and remotely controlled.

The demo site manager, Diego Romera (Empresa Municipal de la Vivienda) said, “SunHorizon project will help to improve the quality of life of the tenants, by attempting to achieve high degree of comfort, reducing to minimum the energy consumption.’’

Furthermore, the “SunHorizon project aspires to become a replicable model for retrofitting EMVS buildings or even new EMVS buildings in the city center of Madrid.”

The technologies installed are provided by the SunHorizon partners: Schneider Electric, BDR THERMEA, DualSun and Ratiotherm. Other partners, Veolia and Cartif, supported the work in the demo site.

The commissioning is scheduled for December 2021.

The SunHorizon technology package #3 (TP3) has been put in place in the Mira-sol civic center (1050 m2), a facility dedicated to cultural activities, located in Sant Cugat del Vallès (Spain).

10 different rooms of the civic center are monitored with CO2, temperature, humidity, window and occupancy sensors. The heating and cooling demands are covered by the hybrid adsorption-compression chiller, high-vacuum solar thermal panels, storage tanks, and advanced monitoring and controls interface components.

The center has a 50 m2 outdoor technical room, where the heat pump is installed, additionally, the building has a large roof surface (350m2) available where the solar collectors have been installed. The high-vacuum solar thermal panels are connected directly to the heating distribution system, thus to reduce the heat pump heat production.

The integration between solar and heat pump technology aims to cover part of the heating and cooling demand of the building, to maximize solar self-consumption and guarantee adequate internal comfort.

As the site manager Gerard Riba (Sant Cugat del Valles City Council) explained, “The SunHorizon solutions applied in the Sant Cugat demo site will rely on renewable, local energy sources to promote feasible alternatives to traditional fossil fuel-based solutions. The solutions are expected to have positive impact in terms of: GHG emission savings (14.6 tCO2/year) and primary energy savings (122.95 MWh/year), reduction of thermal energy bill: 6,147 €/year, and the creation of 10 new jobs, among others.”

The technologies installed are provided by the SunHorizon partners: Schneider Electric, FAHRENHEIT, TVP Solar and Ratiotherm; while Veolia and Cartif supported in the installation, commissioning, monitoring and data acquisition.

The commissioning is foreseen to be finalized between end of December and beginning of January 2022.

 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.
