Question by Rox Tarr: How do small water coolers cool water ?

I am talking about those small coolers (with red and blue tap) with hot and cold water taps used in small offices. Do these coolers entire functionality of a fridge , such as compressors, evaporators etc. ? Or these (cooling part) work on a totally different principle of cooling ?

Answer by dan1221nad
Well, it depends on the type of water cooler obviously. Some of them do have compressors, evaporators, etc. and some use Peltier devices.

If it makes any sort of humming noise, that’s probably the pump, pumping the refrigerant around in the system. If it’s one of those table-top ones which are obviously too small for a pump and all the rest of the stuff, it’s probably a Peltier device. These use semiconductors with the special property that when a DC voltage is applied across the chip, one side gets hot and the other side gets cold. They’re much less efficient than a conventional cooling system, so there’s a trade-off between their small size, lower noise, no moving parts, etc. and their efficiency.
