Where can I find an NTU equation for a counter flow plate heat exchanger?

Click For Summary
The discussion focuses on finding an NTU equation specifically for counter flow plate heat exchangers, as standard textbooks do not provide these equations. A user named Henrik is seeking resources for dimensioning a plate heat exchanger using the effectiveness NTU method. Another participant suggests two online resources that may contain the needed information. The conversation highlights a gap in available literature for this specific type of heat exchanger. Accessing the recommended links could provide the necessary equations for Henrik's project.

Hi

I am woking on a project with dimensioning a plate heat exchanger and are looking at the effectiveness NTU method. The textbooks provide NTU equations for many kinds of heat exchangers but not for plate heat exchangers.

Does anyone knows where I can find an NTU equation for a counter flow plate heat exchanger?Best regards

Hello Henrik, welcome to PF :smile: !

I googled around and found http://www.mie.uth.gr/ekp_yliko/CEP_Plate_and_Frame_HX.pdf and http://www.aidic.it/escape20/webpapers/569Arsenyeva.pdf and a few more.

Thread 'UV filter for home central heating?'

Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now I'm finding out there's more than one type of UV filter: one for the air flow and one for the coil. He was suggesting we might get one for the air flow, but now we'll have to change the bulb...
