METHOD OF CONTROL OF TEMPERATURE OF SPACECRAFT EQUIPPED WITH SOLAR BATTERIES Russian patent published in 2006 - IPC B64G1/50 F28D15/02 

FIELD: control of temperature of spacecraft and their components.

SUBSTANCE: proposed method includes measurement of temperatures in spacecraft temperature control zones, comparison of these temperatures with high and low permissible magnitudes and delivery of heat to said zones at low limits. Heat is delivered by conversion of electrical energy into thermal energy. Power requirements are measured at different standard time intervals of spacecraft flight forecasting orientation of its solar batteries to Sun. Magnitude of electric power generated by solar batteries is determined by forecast results. Measured magnitudes of consumed electric power are compared with forecast data. According to results obtained in comparison, flight time is divided into sections at excess of energy generated by solar batteries over consumed power, equality of these magnitudes and shortage of generated energy. High magnitudes of temperature are maintained at excess energy sections by conversion of difference of generated energy and consumed energy into heat. In case of reduction of generated energy in the course of changing the orientation of solar batteries on Sun, temperature in these zones is reduced to low limits at simultaneous equality of energies. In case of further increase of generated energy, temperature in said zones is increased to high limits at equality of energies. Then, in the course of change of generated energy, temperature correction cycles in temperature control zones are repeated.

EFFECT: avoidance of excess of consumed energy above generated energy of solar batteries.
