This article describes the structure and the operation of energy-saving systems based on a heat pump with the use of renewable energy sources. Using the method of an experiment three-factor active planning, the response surfaces and their two-dimensional cross sections were constructed in the isolines of the transition process duration and the amount of the energy carrier heat from the the electric heater power. The developed energy-saving systems support the temperature regime of an agricultural object by using solar energy, low-potential and artificial energy sources throughout the year. The developed system (option one), installed in hard-to-reach places at agricultural facilities, is designed to generate thermal energy, electricity, and provides significant energy savings during energy supply. Due to the speed of the electric regulator with solid filler and electric heater, the efficiency of the heat pump is increased, which maintains the microclimate parameters of the agricultural object.
