Freezer Build

[ColdEH]

Hi all just rebuilt my freezer on board .

You can do most any insulation projects working though the hole . You will have to build your self a new liner but the is not a huge project , just on the large size , the benefits are astronomical!!

30 year old disintegrating foam with black mold , and a stainless liner .

[ColdEH]

Then new vapor barrier and Polyisocyanurate insulation 5 inches and the last layer on the cold side being blue board XPS.

[ColdEH]

Build a box out of fiberglass , slip it in , measure twice !!

[ColdEH]

I build my own condensing units and evaporator plates , but thats for another thread .

Did this completely through the opening no destruction or reconstruction.

The door will be done with Aerogell to keep it thin.

Regards

[ColdEH]

Yes those are Noctau fans and an all copper condenser .

Nice,
Where did you find a Rolled bond evaporator with no cap tube?

The first one I built I used a NovaKool plate. Now I build my own plates , all copper .

Typhoon. Nice looking work, are you in the business. One way or another would like to talk to about refrigeration. Where do you sail from

There is a void between the box and the insulation?

[ColdEH]

No , this is a really tight fit , measure twice as you build the box Oh hell measure three times . even so you really need to grease the outside of the liner and tap it in slowly . The fridge was even more challenging I had to cut it in two because the liner was to tall to fit under the cabinet and it was bigger then the hole it was going into. Then fiberglass the seem up and paint. Worked out just fine .

So no possibility of moisture getting there?

Have you decided on the evaporator?

[ColdEH]

No not a chance . Two vapour barriers and all the polyiso boards where end taped with vapour barrier tape.
I build my own condensing units using all copper condensers and thin copper flat evaporator plates of my own design . I use a BD35 and a TXV to control refrigerant . They work great , I have built almost a dozen of them now , some with the BD50 and a manual speed controller . I stay away from water cooling and electronics . I see to many posts from people on here with failed units due to crapped out electronics and plunged sea strainers or loss of refrigerant though bad o rings or pin holes in there condensers . Plus, air cooling works on the hard .
