Peltier effect cooling efficiency test

Peltier effect cooling efficiency test.

A peltier module is a solid state device often used for doing cooling. Their found in some portable coolers for carrying food to the beach or in water dispensers like the one shown below.
While they’re useful for those purposes, they’re not very efficient. Only around 5% of the electrical energy used to power them gets used for cooling. I decided to do the simple efficiency test shown here. I wasn’t testing the module directly, but instead testing how efficiently it could cool 250ml of water.
