Thank you for all the feedback, I think I need to explain further actually what I wanted to do .

A little background about myself. I am working in a manufacturing company that requires drying process. The drying process is actually quite simple, fresh air are taken in and heated up before passing through our products. The hot moist air is then partially thrown out to the atmosphere while some recycle back to the drying chamber. This is to ensure that the overall temperature do not drop drastically.

When I came across the articles on TEC, where some mention that the temperature different can be up to 40 degrees Celsius. I was thinking why don’t I try to do the drying in a closed system. All I have to do is channel the thrown out (hot and moist air) to the cold side of TEC where water will condensate leaving dry cold air. I will then channel this dry cold air to the hot side of the TEC which will then heat back the air to its original temperature. The heated air will then be channel back into the drying chamber. Imagine if I am successful in this I will save a lot of fuel which is required to heat the fresh intake air of the drying chamber. The collected water will be recycle back to production which will then reduce the water bill.

Well, it looks simple enough in theory but then why so many other smart guy out there have not thought of it. There must be some catch. I mean some reason why it cannot be done that I do not know of.

Here come the actual reason why I join this forum, I want to learn all I can on TEC but too lazy to go back to the basic of reading. So I will try to ask questions and hope that someone will be able to give me some answers. This way I can learn faster. Hope all of you don’t mind
