Research project
HT-PCM – Feasibility assessment for a high temperature phase change material storage
The project HT-PCM aims at providing a feasibility study of using phase change materials (PCM), e.g. erythritol, as storage solution for temperature ranges in between 110 °C to 120 °C. The storage concept is designed to be integrated with solar thermal collectors to provide solar process heat to industries. The proposed PCM…
Research project
RepicKuba – Climate-neutral cooling with the sun in Cuba
In this project, an air conditioning system is being developed for tropical, humid climate regions that can both cool and dehumidify rooms. A compressor refrigeration machine is used, which is fed directly from a solar system.
Research project
SolarEmmi – Pilot project for solar thermal support of Emmi Fondue
Together with TVP Solar and Planair SA, an industrial solar thermal system with innovative vacuum flat-plate collectors is being built in this project. A plant with a nominal output of 164 kW will be built on an area of 211 m², which will cover around 8% of the heat demand at the site. SPF's contribution includes multi-year…
Research project
PVT-Copras – PVT-Collector with Overheating Protection by Rollbond Absorber Shifting
The aim of the project is the development of a single covered PVT collector with high electrical and thermal efficiency and a self-securing overheating protection realised by absorber shifting. An aluminium roll-bond absorber is used as heat exchanger, which enables good thermal properties on one hand and smart integration of the…
Research project
Innosuisse Flagship RENOWAVE
RENOWAVE is a flagship project of the Swiss Innovation Agency (Innosuisse). It aims to reduce the CO₂ emissions of the Swiss building stock by renovating buildings and switching from fossil fuels to renewable energies.
Research project
SophiA – Sustainable off-grid solutions for pharmacies and hospitals in Africa
Clean water, a reliable power supply and cooling systems for medicines and vaccines are not a given in many rural hospitals in Africa. To ensure better healthcare also in remote regions, the EU is supporting SophiA project, which relies on modular containers to produce drinking water, heat, cold and electricity using solar energy.…
Research project
SolHOOD / Solar energy neighborhoods – Optimal design and operation of heat, cold and electricity supply on the neighborhood scale
In this project, we develop smart planning methods and control strategies for solar neighbourhoods, in order to make optimal use of solar energy, storage solutions, and the interconnection of buildings via electrical and thermal grids. A focus is on the winter heat supply, and alternatives to air/water and geothermal heat pump…
Research project
SolEnEV – Solar energy (PV) self-consumption for heat
SPF has analyzed in more detail the options for self-consumption of photovoltaic electricity for water heating and prepared a fact sheet for EnergieSchweiz. It has been shown that self-consumption through hot water production via heat pumps can be useful by making appropriate adjustments to the running times of the heat pumps.…
Research project
Ice-Grid – Implementation of ice storage tanks into 5GDHC networks
Within the project Ice-Grid possible application of ice-storage tanks in low temperature thermal networks will be analyzed. In combination with other storages, ice-storage tanks can help to shift the availability of heat or cold. As latent heat can be used at 0 °C within an ice storage, this type of storage is of particular…
Research project
BigStoreDH – large heat storage for district heating
Within this project the potential of large thermal energy storages to facilitate the decarbonisation and simultaneous expansion of thermal networks are analysed. Different techniques of short-, medium- and long-term heat storage are considered. The focus is on the replacement of fossil peak load, the increased integration of waste…
Research project
100%solarLCA – Life cycle analyses of different concepts for 100% solar heated buildings
The seasonal storage of heat in 100 % solar thermal heated single and multifamily buildings has been implemented in a number of projects in Switzerland. The first multifamily building with seasonal thermal energy storage that uses a combination of PV and heat pump instead of a solar thermal system is currently being built in…
Research project
CharacSorb – Optimized sorption heat pump for efficiency increase of district heating networks
Sorption heat pumps can provide cooling based on renewable district heat or waste heat, thus expanding the scope of district heating networks (DHN) and making better use of existing renewable heat sources. On the other hand, sorption heat pumps in district heat transfer stations can also provide heat while significantly reducing…
