Abstract
A system and method for cooling a room configured to house a plurality of computer systems. A heat exchanger unit is configured to receive air from the room and to deliver air to the room. The heat exchanger unit is supplied with cooling fluid operable to cool the received air in the heat exchanger unit. At least one of the temperature of the cooling fluid supplied to the heat exchanger unit and the air delivery to the room may be controlled in response to temperatures sensed at one or more locations in the room.
Claims24
A method for cooling a room configured to house a plurality of computer systems, said method comprising:
- providing a plurality of heat exchanger units configured to receive air from said room and to deliver air to said room;
- supplying said plurality of heat exchanger units with cooling fluid from an air conditioning unit;
- cooling said received air through heat exchange with the cooling fluid in the plurality of heat exchanger units;
- sensing temperatures at one or more locations in said room;
- controlling at least one of the temperature of said cooling fluid and said air delivery by said plurality of heat exchanger units to said room in response to said sensed temperatures at said one or more locations;
- and
- manipulating the workload on the plurality of computer systems to optimize energy efficiency in cooling said plurality of computer systems.
A system for cooling a room containing one or more computer systems, said system comprising:
- a plurality of heat exchanger units configured to receive cooling fluid through a cooling fluid line from an air conditioning unit for cooling the cooling fluid, said plurality of heat exchanger units being further configured to receive air through openings in the plurality of heat exchanger units, wherein said air is cooled through heat transfer with said cooling fluid in the plurality of heat exchanger units;
- said plurality of heat exchanger units having at least one fan configured to cause air to flow into and flow out of the heat exchanger unit;
- a heat exchanger controller operable to control a supply of said cooling fluid to said plurality of heat exchanger units and operable to control the speed of the at least one fan;
- one or more temperature sensors for sensing temperatures at one or more locations in the room;
- an air conditioning unit controller configured to operate the air conditioning unit to vary the temperature of said cooling fluid delivered to the one or more locations in the room;
- and
- wherein the air conditioning unit controller is configured to manipulate the workload on the plurality of computer systems by varying the locations where the workload is performed to optimize energy efficiency in cooling said plurality of computer systems.
A system for cooling computer systems housed in one or more racks, said racks being maintained in a room, said system comprising:
- a plurality of means for receiving air from the room, said plurality of means for receiving air being located at various locations of the room;
- a plurality of means for cooling the received air in the plurality of means for receiving air, said plurality of means for cooling including means for receiving cooling fluid from an air conditioning unit;
- a plurality of means for delivering cooled air to said computer systems;
- means for measuring temperatures at one or more locations in said room;
- means for controlling delivery of said cooled air through said plurality of means for delivering cooled air in response to the temperature measurements;
- means for controlling the temperature of said cooling fluid;
- and
- means for manipulating the workload on the plurality of computer systems to optimize energy efficiency in cooling said plurality of computer systems.
A computer readable storage medium on which is embedded one or more computer programs, said one or more computer programs implementing a method for cooling a room configured to house a plurality of computer systems, said one or more computer programs comprising a set of instructions for:
- supplying a plurality of heat exchanger units configured to receive air from the room and to deliver air to said room with cooling fluid from an air conditioning unit;
- cooling said received air through heat exchange with the cooling fluid in the plurality of heat exchanger units;
- sensing temperatures at one or more locations in said room;
- controlling at least one of the temperature of said cooling fluid and said air delivery by said plurality of heat exchanger units to said room in response to said sensed temperatures at said one or more locations;
- and
- manipulating the workload on the plurality of computer systems to optimize energy efficiency in cooling said plurality of computer systems.
