Abstract

A system for cooling heat generating objects arranged in a room. The system adapts in real time to changing cooling demands of the objects. Remote sensors mounted in proximity to the heat generating objects relay information to cooling units, which adjust their operation in response to the information.

Claims (7)

1. A cooling system for cooling a plurality of discrete heat generating objects in a room, the system comprising a plurality of cooling units, a plurality of remote sensors mounted in proximity to the heat generating objects, and a central hub for processing information from the remote sensors and transmitting instructions to each of the cooling units, wherein each of the cooling units comprises a heat exchanger containing a fluid coolant, and wherein the instructions from the central hub to each respective cooling unit control one or more parameters associated with that cooling unit, at least one of the one or more parameters being selected from the group consisting of coolant flow rate and coolant temperature.

2. A cooling system according to claim 1 , wherein the sensor is located adjacent an air intake vent of the heat generating object.

3. A cooling system according to claim 1 , wherein the remote sensors and cooling units communicate with the hub via a hard-wired connection, a wireless connection or any combination thereof.

4. A cooling system according to claim 1 , wherein the at least one sensor comprises a plurality of sensors.

5. A method of cooling a plurality of heat generating objects comprising:

sensing one or more parameters of an environment containing the heat generating object; and

in response to the one or more sensed parameters, independently modulating one or more parameters of at least one of a plurality of cooling units, each of said cooling units uniquely associated with one of the heat generating objects, wherein each of the cooling units comprises a heat exchanger containing a fluid coolant, and each of the one or more modulated parameters is selected from the group consisting of coolant flow rate and coolant temperature.
