How cold does a Peltier cooler get?

Peltier devices are designed to move a given amount of heat when the hot side of the device is at a given temperatures and the cold side is at a given temperature. The cold side for the refrigerator will be around 2.7C for perishables. The hot side would be room temperature so about 21C.

Keeping this in consideration, how cold does a thermoelectric cooler get?

The peltier plate in a standard portable thermoelectric cooler consumes 3-5 amps. It is capable of temperatures that are about 40 degrees Fahrenheit lower than ambient temperature. This means, for example, that if your cooler is sitting outside on an 80 degree day, the coldest it can get is 40 degrees.

Beside above, can a Peltier module cool a room? Peltier junctions produce a temperature difference between one side and the other. This is the temperature they cool with respect to. If they are 60 degrees C on the hot side, and 40 degrees C on the cold side, then it is working and cooling. Sure, both sides are above room temperature, but that doesn't matter.

Secondly, which side of Peltier is cold?

Cooler Modules Place the module on a flat surface so that the wires are pointing towards you with the positive (red) wire on the left hand side and the negative (black) wire on the right hand side. In this orientation the cold side will be facing down and the hot side will be facing up towards you.

How efficient is Peltier cooling?

Peltier effect cooling efficiency test. Peltier cooling effic. 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.
