Abstract:
1. A method comprising: connecting configurable pathways between a sidecar heat exchanger, a liquid to liquid heat exchanger, a rack of information technology equipment, and an outdoor heat exchanger; controlling fluid flow through the configurable pathways based upon at least one of ambient temperature and ambient humidity to remove heat from the rack of information technology equipment; recirculating air flow through the rack of information technology equipment and the sidecar heat exchanger such that the air flow through the rack of information technology equipment and the sidecar heat exchanger is isolated from room air; configuring a first coolant loop circulating a first coolant, the first coolant loop including the liquid to liquid heat exchanger and the rack of information technology equipment; configuring a second coolant loop circulating a second coolant, the second coolant loop including the liquid to liquid heat exchanger and the outdoor heat exchanger; connecting the sidecar heat exchanger to the first coolant loop and not the second coolant loop during a first time period; and connecting the sidecar heat exchanger to the second coolant loop and not the first coolant loop during a second time period.
