Study of thermal performance of a solar collector-based hydraulic system

Abstract

Radiation life support systems, such as solar collectors, are highly efficient, have an almost unlimited resource, and do not use complex technologies. Technologies of heating, heating and hot water supply are implemented quite simply. Such systems use the energy of solar radiation, which is carbon-free, environmentally friendly and renewable. This energy is converted into thermal radiation by solar collectors and transferred to heated rooms using hydraulic or pneumatic systems. For low-rise detached buildings such as cottages and rural houses, hydraulic systems are more promising due to the greater heat capacity of water or non-freezing liquids compared to air. This paper discusses experimental and computational studies of the radiation life support system carried out in 2018–2021. It is possible to determine the thermal performance and geometric dimensions of solar collectors with the accuracy necessary for practice by calculations based on experimental data. It is possible to obtain missing experimental data using interpolation, extrapolation and similarity theory.
