The task of experimental facility design is solved in the paper. The facility intends for investigation of thermalhydraulic processes in a thermal control system of telecommunication satellite. The pumped two-phase loop is used in the thermal control system. The description of experimental facility, its equipment and the results of experimental investigation are presented. The transient stipulated by abrupt units heat load changing was investigated. The conclusions aimed to the system efficiency increasing are formulated on the base of experimental investigation.

Key words: thermal hydraulic process, experimental facility, thermal control system, telecommunication satellite, pumped two-phase loop.
