cooling tower capacity

[moideen]

Hello dears,We have centrifugal chiller 450 ton*2 capacity, and two cooling tower. Each chiller and tower is standby. Last summer (peak time august wet bulb around 88F) chiller was tripped on high discharge pressure when standby cooling tower also working for one chiller. I am from client side and checked the submittals. Found the capacity of cooling tower is 450*2.my question is it the measurement wrong? I heard tower capacity is should be higher than chiller capacity. Consultant submittal says that chiller capacity 450 ton and tower also 450 ton.(still building is not handover being the disput is goin on)Any answer/comments would be appreciated.moideen- dubai
