Provisioning cooling elements for chillerless data centers

摘要

Systems and methods for cooling include one or more computing structure, an inter-structure liquid cooling system that includes valves configured to selectively provide liquid coolant to the one or more computing structures; a heat rejection system that includes one or more heat rejection units configured to cool liquid coolant; and one or more liquid-to-liquid heat exchangers that include valves configured to selectively transfer heat from liquid coolant in the inter-structure liquid cooling system to liquid coolant in the heat rejection system. Each computing structure further includes one or more liquid-cooled servers; and an intra-structure liquid cooling system that has valves configured to selectively provide liquid coolant to the one or more liquid-cooled servers.

1. A method for providing multi-level distributed cooling to a data center, comprising:
providing a flow of liquid coolant to one or more racks in proportion to a number of operating servers in the data center; monitoring a liquid coolant temperature before the coolant has entered into one or more racks; monitoring ambient temperature information; adjusting cooling of the data center in accordance with the ambient temperature information, wherein cooling of the data center is adjusted by decreasing cooling of the liquid coolant if the coolant temperature falls below a first coolant threshold temperature by disengaging one or more liquid-to-liquid heat exchangers, or increasing cooling of the coolant if the coolant temperature exceeds a second coolant threshold temperature by engaging one or more liquid-to-liquid heat exchangers; and turning on additional servers if the coolant temperature is below the first coolant threshold and all liquid-to-liquid heat exchangers have been disengaged.
