Solar community heating and cooling system with borehole thermal energy storage Review of systems
There is a substantial need to accelerate the advancement and implementation of advanced clean energy technologies to solve challenges of the energy crisis, climate change, and sustainable processes. Solar heating and cooling technologies are feasible solutions among clean energy technologies. This paper presents a detailed literature review on studies performed around the solar district energy systems with integrated thermal storage. They are mainly either for heating or cooling. The combined district heating and cooling system with both systems integrated with borehole thermal energy storage (BTES) has not been fully explored. A low temperature distribution fluid, suitable for use in distributed heat pumps around the community with BTES, has also not been practically installed yet. Such system, could reduce the transmission/distribution heat loss within the community, and lower the required amount of energy production and storage, compared to the other systems. This could make the entire system techno economically more attractive while not compromising energy efficiency of the system.
