Solar heating systems offer a sustainable and environmentally friendly approach to warming buildings. To maximize their efficiency, researchers are exploring advanced heat transfer fluids (HTFs) that can enhance the performance of solar thermal collectors. Traditional HTFs, such as water, have limitations in terms of their energy conductivity and viscosity, which can hinder heat transfer. Advanced HTFs, on the other hand, possess superior properties that allow for more efficient capture of solar energy.
These innovative fluids often involve specialized materials such as nanoparticles or organic compounds that exhibit higher thermal conductivities and lower viscosities compared to conventional HTFs. This leads to lowered heat losses during the transfer process, resulting in increased energy output from the solar heating system.
