This page contains all the resources I have on mini-fridges: how different they are from big ones, what technology they use, and how to choose one for your dorm, RV, or small apartment.
- Thermoelectric fridge – works based on Peltier Effect – heat is being transferred from one side of the device to the other using electric power. The side located on the outside of the fridge releases warmth while the other side gets cold and cools the inside.
- Absorption fridge – works by causing the refrigerant to evaporate in a low-pressure chamber when it absorbs heat from the inside of the fridge. Now as a gas, refrigerant gets heated again which makes the gas evaporate out. With no heat, gas is converted back to a liquid and the cycle starts again.
Compressor fridge – works like standard refrigerators causing the refrigerant circulating through a compressor, condenser, and evaporator to change from a liquid into a gas.
If you want to save the energy your mini-fridge consumes, keep it away from any heat source. The quality of the insulating system on a mini-fridge can also affect the energy-efficiency of it. If it is not properly insulated, the room temperature can affect the internal one.
The time they take depends on their size and model, cooling technology, and whether the fridge is placed in a cool place or exposed to the heat or direct sunlight. They also need to be placed at a distance to the wall for the air to circulate and the fridge to function properly.
