1. Select model
The plate heat exchanger model can be customized according to the actual situation. For example, if the flow rate is large and the pressure drop is small, the plate heat exchanger model with lower resistance can be selected, and vice versa.
Those who want to choose a stainless steel plate heat exchanger or a fully welded type can choose according to the specific conditions such as temperature and other parameters. Here, the editor of Kang Jinghui reminds everyone not to choose a plate with a smaller area, which will affect the heat exchange efficiency!
2. Selection of runners and processes
A group of parallel flow channels in the same flow direction of a medium in a plate heat exchanger equipment, similar plates form the flow channel of the medium. Under normal circumstances, many flows are connected in different combinations according to specific processes. To meet different processes.
Calculate according to the parameters and select the process combination form. Under the condition that the refrigeration, heat exchange and other processes can be achieved, try to make the heat transfer coefficients in the flow channels of each medium close to achieve better heat transfer effects.
3. Pressure drop
The pressure drop has a direct impact on the plate heat exchanger, so independent requirements will be set and repeated trials will be conducted until the process requirements are met.
