Parts Of A Refrigerator

Parts of a Refrigerator

These parts are used in all basic refrigeration systems.
Ice machines, air-conditioners, freezers, refrigerators, etc..
The sizing of the parts and equipment are calulated by BTUs.
The more work load or the more space to condition, the higher
the rating of BTUs.

There are five basic parts to any refrigerator:

• Compressor
• Heat-exchanging pipes 
• Expansion valve
• Heat-exchanging pipes 
• Refrigerant 

  
  

The basic mechanism of a refrigerator works like this:

1. The compressor compresses the refrigerant gas. This raises the refrigerant's pressure and temperature.
   

2. As it cools, the refrigerant condenses into liquid form and flows through the expansion valve.

3. When it flows through the expansion valve, the liquid refrigerant  expands and evaporates. In evaporating, it absorbs heat, making it cold.

4. The coils inside the refrigerator allow the refrigerant to absorb heat, making the inside of the refrigerator cold. The cycle then repeats.
