Heat exchange problems in plate heat exchangers
Thread Content
For some reason, the area of the plate heat exchanger used is three times larger than what is actually necessary. With the heat load remaining unchanged and the flow rates on the hot and cold sides staying the same, could such a selection have an impact on the heat exchange efficiency and the rate of scaling? I hope an expert can help answer this, thank you!
Heat exchange will be more thorough, the temperature of the fluid that needs to be cooled will be lower, while the temperature of the fluid on the other side will be higher; as a result, scaling will occur more easily and faster.
Thank you! With a high SS content, scaling will be more severe.
It will definitely be beneficial for heat exchange; check the flow rate to see if it has any impact on scaling.
1. An increased heat exchange area leads to a greater number of plates, which reduces the flow velocity between them and makes scaling more likely； 2. An increased heat exchange area can compensate for the reduction in heat exchange area caused by scaling
Scaling is likely to occur more quickly, but the heat exchange efficiency will be good
