Why? Conventional refrigeration systems are about 8-10 times more
efficient than a Peltier cooler. The only plus to the Peltier is that
you don't have a compressor and circulating fluid, unless you count the
need for airflow over the heatsink to keep the hot-side temperature low
enough so the cold side of the Peltier device has a chance to cool
something other than itself.

I have a small wine-cooler-size Peltier fridge, and that's about all
it's good for (well, substitute soft drinks for wine in my case). The
particular unit I have can't be set to cool below 44F, and practically
speaking, it won't cool more than 15-20F lower than ambient temperature.
During the summer when our kitchen is typically 75-80F, the "cooler"
won't get lower than 60F, and in order to manage THAT, I need to pull it
off the shelf about every other week and give it a good once-over with
an air can to get rid of the dust bunnies that collect on the fan and
heat sink. It also pulls more current than a "dorm-sized" conventional
fridge.

When that thing craps out, I'm definitely not replacing it with another
Peltier unit... what good's a cooler that can't keep beer cold?

Peltier cooler? The name sounds familiar to me.My big G.E.refrigerator
has had it! I am more than fed up with any and all refrigerators that
have a motor/compressor.I am currently using an old Dometic
propane/electric RV vehicle refrigerator which dates back to the 1980s,
it works perfectly, I bought it at a Goodwill store back around 1985.I
want to buy a larger solid state/peltier refrigerator.I don't care if it
(solid state/peltier) uses more electricity, I can afford it.

Wow...

We have one that we take on long road trips that will actually freeze
bottles of tea (not so much my Pepsi, since it's under pressure). I've seen
it get as low as -4C, with the temperature inside the car around 70-75. It
does, admittedly, force a lot of air past a pretty large pair of Peltier
junctions (it draws enough current that I've had to repair the internal DC
power connection once, and the accessory cigar-lighter socket in the car
once.) It's not a really large cooler, about .4 cubic meter or less, so
there's a good ratio for cooling. Biggest hassle I have with it is if the
lid is not tightly sealed, the panel inside the cooler that contacts the
Peltier (to transfer the cooling) will frost up and it gets very inefficient
in a hurry.

One of my FLUKE meters has a thermistor wire thingy which plugs into the
meter.I am going to use it and check the freezer compartment temperature
and also the non freezer part of my old Dometic (Dometic, brand name) RV
refrigerator.I know it gets cold inside there.Sometimes I turn it off
for a while untill the ice inside of the freezer compartment melts so I
can wipe it up.
