Abstract:
1. A method for removing non-condensable gas from a cooling system, comprising: trapping contents of a discharge tube using one or more valves associated with the discharge tube, the discharge tube being associated with a plurality of tubes of a heat exchanger, the heat exchanger in thermal communication with an ambient environment at an ambient temperature, the contents of the discharge tube comprising a vapor portion of a cooling fluid, a liquid portion of the cooling fluid, and a volume of non-condensable gas, the cooling fluid at a subambient pressure, the ambient temperature lower than a boiling point of the cooling fluid; inletting, using the one or more valves, a first additional portion of the cooling fluid into the discharge tube to increase a pressure within the discharge tube; allowing, using the one or more valves, the vapor portion of the cooling fluid within the discharge tube to condense; and inletting, using the one or more valves, a second additional portion of the cooling fluid to purge the non-condensable gas from the discharge tube.
