Abstract
A method of cooling a data centre having at least one hot aisle (145) and at least one cold aisle (144), including the steps of producing cooling air having controlled to have temperature and relative humidity within certain pre-defined limits; supplying the cooling air to a plurality of items of IT equipment (143) located in the data centre between the cold aisle and the hot aisle; measuring the velocity of air flowing from the hot aisle to the cold aisle through an opening (150) between the hot aisle and the cold aisle; and controlling the rate of supply of cooling air to the items of IT equipment in dependence on the velocity of air so measured.
Claims20
A method of cooling a data centre with an evaporative cooling apparatus, the evaporative cooling apparatus comprising an evaporative cooler having at least a first evaporative cooling section, a second evaporative cooling section and a third evaporative cooling section, wherein each section is individually selectively operable, and an adjustably sized aperture arranged as a bypass damper operable to allow air to bypass the sections of the cooler;
- the method comprising the following steps to control an amount of cooling,
- a) operating at least two but not all of the evaporative cooling sections, wherein air is permitted to pass through a non-operational section of the cooler;
- wherein the method further comprises either,
- increasing the amount of cooling by means of:
- b) reducing the size of the adjustable aperture, and
- c) causing a further single evaporative cooling section of the cooler to become operational and at substantially the same time increasing the size of the adjustable aperture by moving the adjustable aperture to a pre-set position,
- or,
- decreasing the amount of cooling by means of:
- d) increasing the size of the adjustable aperture, and
- e) causing a single evaporative cooling section of the cooler to become non-operational;
- wherein air is permitted to pass through said evaporative cooling section of the cooler caused to become non-operational.
