“…After a long period of exploitation of the equipment, a small amount of scale was deposited, which was removed easily mechanically ( Figure 13). The discrepancy between the experimental and the simulation values of heat carrier temperature (in the heat supply system with acoustic-magnetic devices) was estimated using the formula eT = T sim − T exp T sim 100% = 2.3% (16) where eT is the calculated error of the T sim ; T sim is the simulated value; T exp is the experimental value. The discrepancy of experimental and simulated data does not exceed 5%, which allows for confirmation of the validity of the simulation and fairly accurate correspondence to its physical prototype.…”

This article presents the results of the simulation of an automatic control system for the heat supply of a greenhouse complex with a geothermal heat source, conducted in order to study the possibility of geothermal heat supply system automation. Scilab version 6.1 was used for simulation. Based on the results of the simulation, the optimal mode of the automation system function of the heat exchanger primary circuit was developed and implemented. Reagentless treatment of geothermal water in the heat supply system with an acoustic–magnetic device (designed and patented by the authors of this paper) can significantly reduce the intensity of scale formation in the heat exchanger and geothermal heat supply system equipment. It provides conditions for the automation of geothermal heat supply systems of greenhouses with a surface heat exchanger. Using an automation system allows greater accuracy and reliability in maintaining the required temperature regime (18–20 °C) in the greenhouse, reduces the frequency of system shutdown for unplanned cleaning of the heat exchanger and equipment, reduces the complexity of manual operations of heat exchanger and equipment maintenance (removal of sludge, scale) and reduces the economic costs of transportation and heat consumption.
