i am a newbie here and i am in nascent stage of HVAC,i am a projects engineer and recently we had project for upgrading the capacity of the sand processing plant.in this process we cool moulding sand(foundry) .
i need to calculate the new chiller requirement for this process(how much TR chiller unit is to be procured) .
(the existing 133tr air cooled unit is not working,present output given is 20 deg c)
sand qty/hr to be cooled : 150ton
outlet sand required : 120 deg c
outlet sand required : 45 deg c
blower capacity : 30000 cum/hr
inlet air temp : Db 45 deg c @70% rh (rh is so high in rainy season ,so need to be reduced)
outlet air temp : Db 15 deg c @50% rh
water used : normal water
can any body plesae help me out in calculating the new chiller requirement
