Zusammenfassung: | FIELD: heat engineering, in particular, methods for control of heat condition of aerodynamic heating installations, applicable in installations for drying of long-sized products. ^ SUBSTANCE: the method consists in heat-up of the space of the working space to the preset temperature and upkeep of it within the preset range during the preset time by supplying electric current to the electric motor of the rotor heater, rotation of the impeller of the rotor heater an increasing of the speed of its rotation with adjustment of the consumption of heated gas heat-transfer agent fed to the working passage due to variation of the speed of motion of the gas heat-transfer agent, the speed of motion of the heat-transfer agent is varied by variation of the frequency of the electric motor supply voltage, in the stage of heat-up the frequency of the electric motor supply voltage is increased so that the value of the electric motor current would remain constant and equal to the preset value, and in the stage of temperature upkeep within the preset range the requirement of current constancy is neglected, and the voltage frequency is varied within the fixed range. ^ EFFECT: reduced time of warm-up of the working space. ^ 4 cl |
