Claim of US Patent No. 10,716,239

1. A data center cooling system comprising:an indoor portion wherein heat is absorbed from components in said data center by a heat transfer fluid;
an outdoor heat exchanger portion in selective fluid communication with said indoor portion;
a geothermal heat exchanger portion in selective fluid communication with said indoor portion;
a valve arrangement; and
a control unit configured to operate said valve arrangement to switch said data center cooling system from a first mode to a second mode of operation, responsive to measured temperature of said heat transfer fluid entering said indoor portion exceeding a first maximum allowable value and responsive to ground temperature adjacent said geothermal heat exchanger portion being less than a temperature of air surrounding said outdoor heat exchanger portion;
wherein:
said first mode comprises:
geothermal cooling of said heat transfer fluid in said geothermal heat exchanger portion only;
said second mode is different than said first mode and comprises:
ambient air cooling of said heat transfer fluid in said outdoor heat exchanger portion; and
said geothermal cooling of said heat transfer fluid in said geothermal heat exchanger portion.
