Claim of US Patent No. 10,694,642

1. A system for cooling computing devices, comprising:a facility having an interior space that includes a supply air space and an exhaust air space, the supply air space configured to receive outside air from an external environment of the facility, the exhaust air space configured to exhaust heated air to the external environment;
an air inlet coupled to an exterior wall of the facility and configured to deliver outside air to the supply air space from the external environment;
an exhaust air outlet configured to exhaust the heated air from the exhaust air space to the external environment;
a plurality of computing devices arranged within a computing space of the supply air space fluidically connecting the supply air space and the exhaust air space, wherein at least some of the plurality of computing devices include at least one fan of a plurality of computing device fans that, when operable, draw the outside air from the external environment into the supply air space through the air inlet, move the outside air from the supply air space across one or more heat generating components of the plurality of computing devices to cool the one or more heat generating components, exhaust the outside air into the exhaust air space as heated air, and push the heated air within the exhaust air space into the external environment through the exhaust air outlet;
the interior space further including a mixing chamber in which a temperature of the outside air is adjusted via mixing, the mixing chamber disposed downstream of the air inlet and upstream of the plurality of computing devices;
wherein the mixing chamber is at least partially defined between the exterior wall of the facility and an interior wall at least partially separating the mixing chamber and the computing space;
wherein the plurality of computing device fans are configured to provide sufficient airflow of the outside air through the system to cool the plurality of computing devices;
wherein an overall airflow through the system is driven by the plurality of computing device fans and an average temperature of the system is maintained within a desired temperature range by the overall airflow through the system;
wherein the facility is a multi-story facility including a plurality of levels:
wherein the computing space includes a main portion, a first computing floor portion, and a second computing floor portion disposed above the first computing floor portion;
wherein the mixing chamber is in fluid communication with the main portion of the computing space via an air filter: and
wherein the main portion of the computing space is in fluid communication with the first computing floor portion and the second computing floor portion via at least one second air filter.
