How Refrigerator Works

Hello everyone. I hope you are all doing fantastic in your lives. Almost all people have a refrigerator at home, and we know the function of a refrigerator. It is used to cool objects or maintain the temperature.

The refrigerator works on a VCR (Vapour Compression Refrigeration) cycle. Before I explain the topic, Let me clear up a few basics.

  1. Compressor
  2. Condensor
  3. Expansion device
  4. Evaporator.

Due to this, the temperature and pressure will increase. The temperature increases, so the refrigerant converts into vapour. 2. Condensor: The high pressure, high-temperature vapour refrigerant from the compressor flows through the condenser and, due to heat transfer, the temperature reduces and the vapour refrigerant is converted into liquid. 3. Expansion valve: The low-temperature, high-pressure liquid refrigerant from the condenser passes through. As a result, the temperature and pressure both fall precipitously.

Evaporator: There are two main objects in the evaporator. 1. absorb the heat emitted by the object 2. turn the liquid refrigerant into vapour. So, the low-temperature, low-pressure liquid refrigerant from the expansion valve flow in condensing, so due to heat transfer, it gives it a low temperature to object (meaning inside the refrigerator) and absorbs the object's temperature. The refrigerant then converts into vapour form.

Then the cycle repeat.

I hope you guys like it. Leave any suggestion in comment section.
