FIELD: engines and pumps. ^ SUBSTANCE: proposed method consists in that electric power fed to heater is limited subject to relationship where: W, Wmax are electric power, G, Gmax are working air flow rate, T, Tmax are working air temperature. Proposed method is implemented in proposed unit with the help of logical control unit. The latter is arranged between heater and heater load setting device and provided with converters of working air (fed to heater) parameters into electric signal. ^ EFFECT: overheat protection. ^ 2 cl, 1 dwg |
