I wanted to put this up as a separate thread so people can find it easier. I recently built a 42.5cu.ft. maturing chamber using a Stainless Steel double door commercial freezer. I used Peltier TEM technology for the cooling system. The cooling water used in that system does not go below the dew point of the chamber so there is no condensation on the cooling cycle. Thus, I needed a way to remove moisture efficiently. A compressor dehumidifier is way more efficient than a peltier system so that is what I used. I basically followed this youtube for my build:
Except I used a magic chef freezerless 1.7cu.ft. refrigerator because it already had a drain with the cooling plate situated vertically over the drain. I just needed to make a couple baffle plates to divert the air over the cooling plate.
Fabricating the baffle plates:
The mounting brackets for the baffle plate over the cooling plate..I used some 2" C channel. secured the spacers in place with gorilla glue for easier install.
Made some spacers out of 1/2" HDPE to move the cooling plate out from the wall for better contact with the air for dehumidification.
The 1 1/2" intake hole in the dehumidifier refrigerator, clips installed on the cooling plate.
The outlet hole in the dehumidifer refrigerator went through the back wall by the compressor to avoid condenser lines in the sides of the refrigerator., you can see the lower baffle plate clips installed here:
Outside view; You can also see the water drain hose right there in the middle of the picture. I just slipped a 3/8" vinyl hose on it and it was good to go.
The intake fitting installed in the chamber ceiling:
The 1 1/2" outlet fitting installed in the chamber...this is where the header is placed over the outlet.
Baffle plate over the cooling plate installed in the little refrigerator, return air fan installed:
Top baffle plate installed in the little refrigerator, sealed with silicone:
The intake and outlet hose orientation on top the cabinet:
That one screw behind the temperature adjustment was a PITA to install! Had to use one of those small screw tip hand ratchets and get one small bite at a time.
