FIELD: transport.
SUBSTANCE: invention relates to ground simulation of thermal control system operation, primarily, of telecommunication satellites equipped with duplicate liquid circuits. In testing thermal model in both standard liquid circuits, standard liquid heat carrier circulates. One shared hydraulic accumulator (instead of two) is used to maintain operating pressure in said liquid circuits, accumulator chamber being communicated with liquid lines of both circuits. Electrically driven pump units arranged in every liquid circuit ensure required flow rates of heat carrier. Said pump units comprises one main hydraulic pump, with no standby pump.
EFFECT: simplified design.
