Original abstract
Energy systems around the world require a sustainable way for energy supply that does not add carbon to the atmosphere and thus reduces the greenhouse effect, The reduction of carbon dioxide emissions and increasing of energy efficiency for residential heating can be performed by implementing RESHeat (Renewable Energy System for Residential Building Heating and Electricity Production) system, which combines solar energy, thermal storage and ground heat pumps. The present work analyses the possibility to regenerate the ground heating capacity for the heat pump by utilizing a heat storage tank, which accumulates waste heat from the photovoltaic panels and the sun-tracked solar collectors. A mathematical model of heat dissipation in soil from the underground heat storage tank filled with water was developed, employing the tank temperature, soil content and its humidity as input parameters. The CFD simulation based on a Finite Element Method was carried out for different time periods. The implementation of low-potential waste heat increases the average COP of the heat pump up to 5.5.
