DATA CENTRE COOLING SYSTEM

摘要

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.
