How a Mini Fridge Works
A mini fridge is a compact refrigerator designed to provide convenient cooling for small spaces such as offices, dorm rooms, or even as a secondary storage unit in your kitchen. Despite their smaller size, mini fridges function using the same basic principles as regular refrigerators.
Overview of Mini Fridge Functionality
Mini fridges work by utilizing a compressor and a refrigerant to remove heat from the interior compartment, thereby cooling the contents stored inside. The compressor compresses the refrigerant, increasing its temperature and pressure. The heated pressurized refrigerant then flows through a condenser coil, dissipating heat and converting it into a liquid state.
Once the refrigerant has been cooled and condensed, it passes through an expansion valve, which reduces its pressure. This sudden decrease in pressure causes the refrigerant to evaporate, absorbing heat from the interior compartment of the mini fridge. The evaporating refrigerant then returns to the compressor to repeat the cycle.
