Abstract
Systems and methods for cooling a datacenter are disclosed. In at least one embodiment, an absorption chiller includes a generator vessel to enable removal of heat from fluid returned from at least one computing component of the datacenter.
Claims22
A heat recovery system, comprising:
- an absorption chiller comprising a generator vessel to couple to one or more computing components in a datacenter via a primary cooling loop to receive heat from fluid returned from the one or more computing components;
- a secondary coolant associated with a secondary cooling loop and operatively used as the fluid;
- and
- one or more flow control valves associated with the secondary cooling loop to enable diversion of the secondary coolant from the secondary cooling loop to the heat recovery system and to enable return of the fluid to a cooling distribution unit (CDU) or to the one or more computing components.

A datacenter cooling system, comprising:
- a generator vessel to couple to one or more computing components in a datacenter via a primary cooling loop to receive heat from fluid returned from the one or more computing components, the generator vessel comprised in an absorption chiller within the datacenter cooling system;
- a secondary coolant associated with a secondary cooling loop and operatively used as the fluid;
- and
- one or more flow control valves associated with the secondary cooling loop to enable diversion of the secondary coolant from the secondary cooling loop to the generator vessel and to enable return of the fluid to a cooling distribution unit (CDU) or to the one or more computing components.
1 more element
A method for a datacenter cooling system, comprising:
- providing a heat recovery system comprising an absorption chiller comprising a generator vessel;
- coupling the generator vessel to one or more computing components in a datacenter via a primary cooling loop to receive heat from fluid returned from the one or more computing components;
- determining that fluid returned from the one or more computing components has heat addressable by the absorption chiller;
- enabling the generator vessel to cause removal of at least one part of the heat from the fluid;
- providing a secondary coolant associated with a secondary cooling loop to be operatively used as the fluid;
- enabling diversion of the secondary coolant from the secondary cooling loop to the heat recovery system;
- and
- enabling return of the fluid to a cooling distribution unit (CDU) or to the one or more computing components.
