How Mini Refrigerators Work
Like all refrigerators, mini models rely on the principles of thermodynamics to transfer heat from inside the unit to the outside. This process involves several key components, most notably the compressor, condenser, evaporator, and refrigerant.
- Compressor: The compressor compresses the refrigerant and pumps it into the condenser.
- Condenser: In the condenser, the refrigerant dissipates heat and transforms into a liquid state.
- Expansion valve: The refrigerant then moves to the expansion valve, where it undergoes a pressure drop, turning it back into a gas.
- Evaporator: Finally, in the evaporator, the refrigerant absorbs heat from the interior of the refrigerator, cooling down the space.
The role of refrigerants like Freon or its alternatives is crucial for maintaining this cycle efficiently.
What is Freon?
Freon is a brand name that refers to a class of chlorofluorocarbons (CFCs) and halocarbons that were commonly used as refrigerants in air conditioning and refrigeration systems. The original formulation was developed in the 1920s, and it quickly gained popularity due to its effectiveness and safety compared to other available chemicals at the time.
