“ In London North , we replaced the two legacy cooling systems with one common system comprising free-cooling chillers ,” Winter explains . “ We also replaced all the CRAH units within technical suites and elevated the temperature of the water that is used as the medium to circulate cooling to the suites while also raising the leaving air temperature from the computer room air handlers to the servers under a supply air control strategy to reduce energy consumption ; the data centre had historically been developed with return air control .
“ In the redeveloped spaces where we have fan walls installed , the design has been validated by CBRE meaning they calibrated
