Mathematical Modeling of the Combined Heat Supply System of a Solar House

Today, increasing energy efficiency in residential heating systems, saving fuel and resources, improving the of using devices based on renewable sources is an urgent issue. The purpose article to develop a mathematical model heat balance conduct theoretical study one-story rural houses use solar non-stationary mode. To achieve this goal, experimental house with autonomous supply was built. mainly uses energy, when load exceeds load, traditional boiler device used. power provided by panel (photovoltaic converter). A scheme for electrothermal physical are proposed. Based proposed schemes, calculation algorithm equation dynamic state system mode have been developed. On basis modeling, influence capacity wall structure temperature regime building studied. MATLAB-Simulink program, main characteristics were built, which change internal air analyzed depending ambient temperature. modular scheme, results experiment changing inside outdoor presented form graph. thermal obtained recommended development energy-efficient houses.
