Heating / Cooling Electrical Question
Hey Guys,
Hope everyone is having a great holiday season. As many of you know, I am waiting to hear from some positions that I have applied for and in the mean time I have hired on locally as an HVAC instructor at one of the local technical colleges. I have a question in reference to a water cooler that a student has brought in to work on . This unit is one of the cheap stand alone units that run about $100. at Wally World. I noticed that this thing does not appear to have a compressor or regular cooling system, which leads me to believe that it is working under the same principals as those little cooler/heaters that you plug into your cigarette lighter of your car. My question is does anyone know how these things work... I don't have any experience with these and thought I would pass the question on to you guys... maybe someone understands or knows the working theory behind them.... thanks in advance...

If it's a so-called "swamp cooler" it works off of simple evaporation. Evaporating water is a highly endothermic process and effective at removing heat.

Hey POP thanks for the reply.. No, it isnt a swamp cooler, I am familiar with those. This unit is one of the coolers that you would put a 5 gallon bottled water bottle upside down onto. You can buy them for your house or office, and they sell them at wal mart. I think that those small cooler/heater chests that you buy at Cabela's/Academy work with some kind of micro chip that causes the cooling/heating effects... Since this unit does not appear to have a compressor, condensor etc.. I figured it worked under the same theory as the other travel chests you can buy. I noticed that it did have two cooling fans over what appeared to be a condensor of sorts, but electrically speaking like on a stereo amplifier.

Maybe thermoelectric cooling? http://en.wikipedia.org/wiki/Peltier_cooler
