Information technology equipment cooling method

摘要

According to one embodiment, a system for removing heat from a rack of information technology equipment may include a sidecar indoor air to liquid heat exchanger that cools air utilized by the rack of information technology equipment to cool the rack of information technology equipment. The system may also include a liquid to liquid heat exchanger and an outdoor heat exchanger. The system may further include configurable pathways to connect and control fluid flow through the sidecar heat exchanger, the liquid to liquid heat exchanger, the rack of information technology equipment, and the outdoor heat exchanger based upon ambient temperature and/or ambient humidity to remove heat generated by the rack of information technology equipment.

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.
