Vietcombank - Chiller Plant Sizing for Tender1/04/2010

Plant total load 7860.5 kW *

Plant total load with diversity 7074.5 kW apply further 10% diversity for people, lighting and equipment

Data centers load 1230.6 kW allow for 350Tr; no diversity on data centres loads

Data centers load 0.6153 kW/sqm

Data center area 2000 sqm estimate

Office average load 0.181 kW/sqm

Office load@2000 sqm 362.2 kW

Plant sizing revise =Plant total load with diversity-(Office load@2000sqm)+(Data center load@2000sqm )

Plant sizing revise = 7943 kW

3 main chillers = 2648 kW 756 Tr say 750 Tr

2 standby/low load chillers = 1324 kW 378 Tr say 375 Tr

* Coincident air system cooling loads (includes solar/facade diversity) from E-20 Cal (R1)*

* Facade glass U=1.6W/m2K; SC=0.5
