Abstract

As a result of the depletion of traditional fuel and energy sources in the world and the increase in the burden on the environment, the issue of saving and efficient use of natural fuel and energy resources is becoming one of the urgent problems on a global scale. Special attention is also paid to the issue of providing households with autonomous heat supply systems using sustainable energy resources in conditions of a sharply continental climate. In this article, the authors have developed a heating scheme for a rural model house with an heat pump unit (HPU) and a warm floor heating system with a heat accumulator. The heat balance equation for the developed rural model house with an HPU and a warm-floor heating system with a heat accumulator was developed using thermal engineering and heat-exchange methods. The calculations were carried out using the Matlab Simulink software package. The results of numerical modeling using the Matlab Simulink software package showed the need to determine the optimal ratio between heat sources and heat losses to ensure a stable microclimate in the room in the range of 20÷24 °C.
