Abstract
According to one embodiment of the present invention, there is provided an apparatus for cooling a data centre. The apparatus comprises an air conditioning unit for supplying cooled air to a cold portion of a data centre, an airflow measurement device for measuring a rate of bypass airflow through a segregation between the cold portion and hot portion of the data centre, and outputting a bypass airflow signal indicative of the rate of bypass airflow between the cold portion and the hot portion, and a control unit arranged to receive the bypass airflow signal from the airflow measurement device and to output a control signal to a means for controlling a rate of the bypass airflow to maintain a predetermined rate of bypass airflow.

An apparatus for cooling a data centre, comprising:
- an air conditioning unit for supplying cooled air to a cold portion of a data centre;
- said air conditioning unit comprising:
- an airflow measurement device for measuring a rate of bypass airflow through a segregation between the cold portion and hot portion of the data centre, and outputting a bypass airflow signal indicative of the rate of bypass airflow between the cold portion and the hot portion;
- and
- a control unit arranged to receive the bypass airflow signal from the airflow measurement device and to output a control signal to a means for controlling a rate of the bypass airflow to maintain a predetermined rate of bypass airflow.
A method of cooling a data centre which is segregated into a cold portion and a hot portion, said method comprising:
- determining a level of bypass airflow between the cold portion and the hot portion of the data centre;
- and
- controlling the bypass airflow to maintain a predetermined level of bypass airflow.
