Cooling system, air removal attachment, air removal method, and storage medium

An air removal method of an attachment for a cooling system having at least one heat exchange condenser, the air removal method comprising:

• detecting a presence of a fluid at a position along an exhaust flow path of the attachment;
• exhausting air from the attachment by opening a valve along the exhaust flow path based on the detection of the presence of the fluid;
• and
• blocking the exhaust of air by closing the valve in absence of the detection of the presence of the fluid.

A server rack cooling system comprising:

• a server rack;
• an evaporator configured to remove heat generated by the server rack by way of a refrigerant flown through the evaporator and configured to maintain a lower pressure than the outside air pressure;
• at least one heat exchange condenser configured to cool the refrigerant and into which refrigerant from the evaporator is flown;
• a pipe extension which connects to the at least one heat exchange condenser;
• a valve on the pipe extension configured to allow exhaust to the outside through the pipe extension at an open position and to block exhaust to the outside at a closed position;
• and
• a sensor disposed at a position inside of the pipe extension between the at least one heat exchange condenser and the valve and configured to provide a detection signal determined by a presence of fluid at the position of the sensor,
• wherein, the valve is opened and closed based on the detection signal from the sensor.
