A Compact Refrigerator is also known as a mini refrigerator.

Compact and Mini denotes the size of the refrigerator. There are two distinct designs of a compact refrigerator; one has a miniature freezer and the other does not.

A compact refrigerator with a miniature freezer compartment has its evaporator (miniature freezer compartment) on the upper side of the inner space.

Manufacturers use light aluminum, copper, or iron sheet to make the evaporator, although they prefer aluminum because it is a good conductor of heat, and it is not as expensive as copper.

The evaporator looks like a small cabinet with a door. It occupies a quarter, or less, of the whole compact refrigerator’s storage space, and the remaining space is cooler ( does not freeze stuff, that is).

A mini refrigerator would be good for you if you don’t need a lot of frozen items or, if you have a dedicated freezer, a compact refrigerator can supplement it.

Compact refrigerators come in different sizes of between less than a cubic foot, and higher. This makes them ideal for bedside, outdoor recreational area, gaming room, or home office.

The inner storage space of a compact refrigerator, excluding the “small freezer,” is also ideal for wine bottles and other brittle-glass bottled drinks.

Mini refrigerators are available in different colors that carter for variable tastes.

The mini refrigerator runs on minimal electricity if you compare with a two-door refrigerators because its compressor is smaller. Compressor is the engine (motor) that pumps refrigerant in the refrigerant cycle.

There is another design in mini refrigerator category  with a small fan inside the refrigerator compartment. The fan stirs cold air in the refrigerator to make cooling even.

Control components in a mini refrigerator needs to be in working condition. One component is the thermostat. It automatically switches off the compressor when temperature inside the refrigerator reaches optimum low level, and then switches it on when the temperature rises.

Thermostatic off-and-on switching is a regular process that if you analyze the sum total of ‘stop-time’ and the sum total of ‘run-time’ within 24 hours, you will find that you saved on electricity.

If you compare electricity consumption of a compact refrigerator which has a functional thermostat with one that has a faulty thermostat, the later uses more power. Reason, the refrigerator with the faulty thermostat runs non-stop. The thermostat does not regulate its running.

A compact refrigerator is quiet operating because the sound of its running compressor is low. You have to be keen to hear the thermostatic stop-start of the compressor.

There are mini refrigerators that run on Direct Current (DC) electricity. “Direct Current” electricity is the same as that of a flashlight or car battery and, for a refrigerator, the sun or conventional national grid is the electrical energy  source.

A refrigerator that runs on DC is more economical and Eco-friendly.

If your house connects to the national grid Alternating Current (AC) electricity, an inverter inside your refrigerator converts AC current from the wall socket to DC.

Even though that sounds technical, however, you don’t need technical knowhow for your refrigerator to function. Just plug the refrigerator into wall socket and enjoy your refrigerator service.

All the work of AC to DC power conversion happens in invisible electronic components inside the fridge.

There are models that manufactures fit with “electronic cooling system” instead of the compressor motor. We’ll talk about this kind of cooling in another article.
