This article presents the results of the design of acoustic–magnetic device thermal protection technology based on simulation. The acoustic–magnetic device (AMD) was installed in the heat supply system of a greenhouse complex with a geothermal heat source, developed and patented by the authors of this paper. Simulation was performed to investigate the possibility of maintaining the acoustic transmitter temperature of the acoustic–magnetic device in its operating range. The QuickField Student Edition v 6.4 simulation environment was used for this purpose. Based on the results of the simulation, the optimum thermal mode of the acoustic–magnetic device was developed and implemented. The optimum temporal operating mode of the acoustic–magnetic device is necessary for the optimization of the non-reagent treatment of geothermal water in a heat supply system of a greenhouse complex. It allows for a considerable reduction in the intensity of scale formation in the heat exchanger and equipment of a geothermal heating system. As demonstrated by the simulation thermal modes, the acoustic–magnetic device provides conditions for the work maintenance of the AMD acoustic transmitter at the resonance frequency, reduces the power expenses, and increases the efficiency of the acoustic influence on the scale formed in the heat supply system of a greenhouse complex. The results of the simulation were implemented in the greenhouse complex of JSC “Raduga.” The thermal protection technology was realized by installing two acoustic–magnetic devices and automation systems in the geothermal heating system a greenhouse complex.

Objectives. The study was aimed at improving the reliability of heat supply systems. At present, this is one of the most relevant topics in the field of heat supply. The issue of reliability of heat supply is of great importance in terms of the safety of citizens and the state as a whole. Due to the severity of winter conditions and risk of hypothermia, heat supply security can be considered to be as critical as food security. Therefore, the reliability of heat supply systems becomes one of the most important aspects of the security of the state.Method. The study was carried out using the method of reservation of the heat supply system by looping.Result. In order to avoid the defrosting of the heat supply system and reduce additional costs, a redundancy scheme was proposed with one-way connection to the looped main pipelines, additionally looping the pipelines of the heat supply systems between two boiler rooms. The calculation of losses in the event of an emergency in the heating system was carried out.Conclusion. The most important problem requiring immediate solution is how to increase the reliability and redundancy of the heat supply system itself, in order to achieve minimal discomfort for consumers of heat energy at the time of failure of the source or transmission of the heat supply system. The proposed method for increasing the reliability of operation of heat supply systems is characterized by a high efficiency, since allows the number of idle hours and the total amount of short-received heat to be reduced.
