FIELD: space engineering.
SUBSTANCE: proposed system includes main fan, gas-flow duct, condensate discharge unit, gas cooling and dehumidification loop and gas-and-liquid heat exchanger of heat pick-up loop. Gas cooling and dehumidification loop is provided with closed main with phase transition; this loop includes the following components mounted in succession: compressor, coolant condenser, throttle valve, main and additional gas-and-liquid evaporators. Gas inlet passage of additional evaporator is brought into communication with gas duct of ventilation system at outlet of gas-and-liquid heat exchanger; outlet passage is brought into communication through additional fan at main fan inlet.
EFFECT: increased cooling effect at reduced mass.
