Condenser selection
Thread Content
Our company intends to change the original four-pass design of the constant-pressure condenser to a two-pass design. I would like to ask those with experience: what will be the cooling effect? Is it possible?
The key is to monitor the flow rate of the process medium; it’s acceptable as long as the flow remains in a turbulent state. Is the reason for changing from four pass systems to two pass systems the fact that these systems are prone to blockage? Generally, when going from four pass systems to two pass systems, the flow velocity inside the pipes is reduced by half; it may be difficult to maintain a turbulent flow state, and the heat transfer coefficient inside the pipes decreases significantly. When designing heat exchangers, energy consumption must be taken into account, so the flow velocity inside the pipes cannot be too high. As a result, the cooling efficiency decreases after this change.
