thanks for the good advice |PuNiSh3R|! i was thinking it was feasible too. the issue with small air leaks is all but removed with an evaporator since, as you stated, the humidity contamination will freeze on it. i would certainly grab the phase-change system off of a "dorm-fridge" as you recommended. maybe the well insulated fridge casing itself can also be used (just bolt the door shut & mount a double-pane window in it). one issue that may come up with this config is the duty cycle of the compressor. i'm not sure about bypassing the thermostat altogether, since the 100% duty cycle could trash the compressor in short time. i was thinking that the inside would have enough "cooling mass" (specific heat) to keep the system cool during off cycles. maybe a circulating fan can be left on all the time to even out the component temperature differences between cycles & the thermostat could be set to keep the air at a somewhat constant temp. how does that sound |PuNiSh3R|? any thoughts from experienced & knowledgeable phase-change ppl would help.
