    Operational Protocols
    Capillary evaporator test performance aboard the ISS RS. The experimental equipment is a monoblock and consists of a capillary evaporator configured as a circuit (CPL1) and an electronic control unit. The capillary evaporator design uses a two-phase heat transfer loop, which is used to support satellite thermal control. The loop consists of an evaporator, cooler and reservoir connected by pipes. The heat generated in the evaporator is transferred by working fluid to the cooler section. The reservoir supports the temperature inside the loop and the required reserves of working fluid. The fans provide cooling of the capacitor. The electronic unit consists of a computer with a single-board microprocessor for data acquisition and regulation of the capillary evaporator power, as well as for setting an operating temperature in the reservoir. Water in amount of 20 ml will be used as a coolant.
