Russian scientists together with the European colleagues create a solar-powered heating system


Novosibirsk scientists together with their European colleagues are creating a solar-powered heating system. Scientists from the Institute of Catalysis of the Siberian Branch of the Russian Academy of Sciences in Novosibirsk, in particular, are responsible for the creation of one of the most important components of the installation - selective water sorbent.

Scientists of Federal Research Center "Institute of Catalysis. G. K. Boreskov of the Siberian Branch of the Russian Academy of Sciences” are involved in the creation of the SWS-HEATING installation, which will accumulate solar heat in the summer in order to heat the building with it in the winter. It is planned to use it in small houses in Europe (including Northern Europe). Novosibirsk researchers are creating for this installation one of the main components - selective water sorbents.

Selective water sorbents are composite adsorbents consisting of a porous matrix, inside of the pores of which there is an inorganic salt, capable of interacting with vapors. "In the summer, solar heat is used to dry this adsorbent, that is, to desorb water vapor from it. If there is a need for heat, we combine the dry adsorbent with an evaporator containing the working fluid (for example, water), and the reverse process occurs, at the same time heat is released, which can be used for heating ", - the TASS press service quotes the research manager, head of the group of energy-accumulating processes and materials of the EC SB RAS Yuri Aristov.

The installation will collect solar heat, and then direct it to heat water up to 60 degrees. The system will “charge” the drive itself, that is, regenerate the adsorbent and send solar energy to the heat buffer, which allows for the redistribution of heat. For example, if at the moment hot water in the house is not used, and the container with it is already fully heated, then heat can be transferred to the storage part through a buffer. The drive will allow you to store warmth for a long time, providing a house with heating in the winter.

SWS-HEATING is not suitable for use in Siberia and most other regions of Russia, but there are very favorable conditions for this installation in Europe. It is assumed that using such systems will help provide about 60% of the thermal energy required by a small private house in the north of Europe, and about 80% in the south. The technology is currently under development. The ultimate goal of the project is the creation of installations that will be sold on the market and which can be installed in existing houses.

The SWS-HEATING project, which included representatives of many European scientific organisations, received the European Union grant Horizon 2020. Horizon 2020 is the largest research and innovation programme in the history of the European Union with a budget of around € 80 billion for seven years (from 2014 to 2020). It should contribute to an increase in the number of innovative technologies, discoveries and promising developments by promoting ideas from scientific laboratories to the market.
