Abstract

The concept of optimizing heating costs for a separate residential building at the expense of supplying the energy transformed by the heat pump to the home and the changes in the heat energy losses everywhere external walls is presented in this work.
The main purpose of the article is to determine the rational modes of operation of the heat pump, on the condition that there is compensation for the cost of heat through the walls of the building. This allows to adjust the heating costs of the building through the use of a heat pump, reducing the coefficient of thermal conductivity of the material of the walls of the house and saving electricity. Electricity savings result from reducing the heat pump's operation and reducing heat loss through the walls of a residential building. Calculation of thermal energy losses through the walls was carried out on the basis of calculations of tabular data and research on the operation of the heat pump, which were carried out on the basis of the physical model of the thermal installation. In assessing the economic efficiency of the heat pump it takes into account the difference in size of market rates for equivalent amounts of electricity and heat as the heat pump to work consumes electricity and useful thermal energy is consumed. With the integrated use of the heat pump and a 41.5% reduction in the coefficient of thermal conductivity of the material of the walls of the building, it will allow an additional 43.5% increase in the cost of heating.
