She wants sympathy, not solutions. I am after neat tidy permanent solutions. I know how to compute most of these things, I was just disappointed that the refrigerator did not have more cooling power. I spent part of the afternoon designing various TEC solutions.
None are very good.
You end up with two cooling loops. But the head is all designed, and there is really no room without a lot of redesign. I just need about 10 C more. At the moment I just have a plastic window on the head. I could put in one of the filters and pump it down with a vacuum pump.
