Claim of US Patent No. 10,398,064

1. A cooling arrangement for air conditioning an IT environment housed inside a building, the cooling arrangement comprising:a cooling unit housing for cooling the IT environment;
a first heat exchanger packet included with the cooling unit housing;
a first blower included with the cooling unit housing, wherein the first blower is disposed to draw air from the building into the cooling unit housing through a first housing side of the cooling unit housing, to convey air through the cooling unit housing and the first heat exchanger packet, and to blow air out of the cooling unit housing over a second housing side located opposite the first housing side;
a second heat exchanger packet for disposition outside of the building housing the IT environment;
at least one second blower for blowing air through the second heat exchanger packet;
a passive cooling circuit and a compressor cooling circuit fluidly separate from one another and both extending between the first heat exchanger packet and the second heat exchanger packet;
a condenser of the compressor cooling circuit, the condenser included in the second heat exchanger packet;
an air-coolant heat exchanger of the second heat exchanger packet through which the liquid coolant of the passive cooling circuit is conducted; and
a recooler housing including the condenser vertically stacked on top of the air-coolant heat exchanger of the second heat exchanger packet, such that air vertically passing through the second heat exchanger packet passes successively through the air-coolant heat exchanger of the second heat exchanger packet and then the condenser.
