FIELD: heating.SUBSTANCE: invention relates to control of operation of thermal control systems (TCS) of automatic space vehicles (SV) at earth orbits. The method consists in the fact that at stationary thermal loading provision of temperatures of honeycomb panels (HP) is performed by passive devices at the level of a nominal value of allowable temperatures of instruments installed on the same HP. At reduced SV thermal loading, HP temperature is controlled by electric heaters (EH) in the temperature range of the lowest possible value to the nominal value. This range is broken down into two or more intervals including at least one interval of the lower limit and one interval of the upper limit of the range. At deficit of electric power aboard SV, HP temperature is maintained by means of EH at the specified interval of the lower limit, and if electric power is available - at the specified interval of the upper limit. Capacity of each EH does not exceed stationary energy release of instruments of corresponding HP.EFFECT: improvement of temperature stabilisation of instruments installed on HP with simultaneous improvement of reliability, reduction of weight and energy consumption of TCS.2 cl, 1 dwg |
