This post was last edited by A window that won’t close_KEIQ on 2018-6-23 07:47. For a plate heat exchanger, the inlet temperature on the hot side is 150°C with a target outlet temperature of 50°C, while the inlet temperature on the cold side is 30°C with a target outlet temperature of 130°C. Is it possible to design such a heat exchanger? Assuming that the specific heats on both sides are the same and the mass flow rates are equal, please provide some insights
Original poster, your premise is incorrect. With the same heat capacity and the same mass flow rate, theory dictates that there must be an equal temperature difference between the hot and cold sides in order to maintain energy conservation. In your case, the temperature difference is 100 on one side and 80 on the other – how can a design be created under such uneven conditions? The data provided by the brother in the second comment show that if the temperature difference remains unchanged, the mass flow rates will necessarily differ
The 2L data clearly does not meet the requirements. . . . . There can’t be such a design! ! !
What kind of software is this? Can it be shared?
The temperature difference is the same; I made a mistake in writing down the temperature on one side. I just want to know what the maximum temperature that can be achieved with plate heat exchangers is, under the current manufacturing processes. Thank you
Could you share this software? Thank you so much
OP, I took a quick glance before leaving last night; I didn’t look closely enough~~~ The conditions are: “Assume the specific heats on both sides are the same, and the mass flow rate is the same”~~~ It’s not possible to design this unless a portion of the flow is directed for air cooling (;P)~~~ I borrowed the software from a colleague; I’ll ask him tomorrow if he still has the installation files~~~ HTRI doesn’t even have a heat exchanger module~~~ :L:L
