Sistema Obespecheniya Teplovogo Rezhima, SOTR
The system is designed to maintain normal temperature (18 - 25 degrees C) and humidity ( 20 - 80 percent) inside habitable sections of the spacecraft and the nominal temperature (0 - 40 degrees C) for the vehicle's systems and structures. The system includes both active and passive elements, among them thermal insulation known by its Russian acronym EVI, for Ekranno-Vacuumnaya Izolyatsiya, EVI, a ventilation system, and internal and external liquid cooling loops.

A classical seven-ton Soyuz vehicle consists of three major components, providing for every stage of flight from orbital insertion to landing. To protect the ship's systems from extreme temperature swings in space, all its surfaces exposed to space, except for active elements of sensors, antennas, windows, the docking hardware, thruster nozzles and radiator panels, are blanketed by multilayer vacuum-screen thermal insulation.
