Which compressor used in refrigerator

The most common types of compressors used in refrigerators are reciprocating compressors and rotary compressors.

Reciprocating compressors use a piston and cylinder to compress the refrigerant. They are typically used in smaller refrigeration units, such as domestic refrigerators, as they are less expensive and easier to repair than rotary compressors.

Rotary compressors use a rotor that rotates inside a cylinder to compress the refrigerant. They are typically used in larger refrigeration units, such as commercial refrigerators, and they are more efficient and have a longer lifespan than reciprocating compressors.

Another type of compressor used in refrigeration is scroll compressor, it uses two interleaved spiral-like vanes to compress the refrigerant. They are considered to be more efficient and quieter than reciprocating compressors, and are used in high-end domestic and commercial refrigeration units.

In summary, the most common compressors used in refrigerators are reciprocating, rotary and scroll compressors. The type of compressor used depends on the size and purpose of the refrigerator and the efficiency and durability required.

Where is refrigeration compressor used?

Refrigeration compressors are used in a wide range of applications, including:

  1. Domestic refrigerators: Compressors are used to cool the interior of a refrigerator and keep food and other perishable items fresh.
  2. Commercial refrigeration: Compressors are used to cool large refrigeration units in supermarkets, restaurants, and other commercial settings.
  3. Air conditioning: Compressors are used to cool the air in buildings by compressing and circulating refrigerant through a system of coils and ducts.
  4. Industrial refrigeration: Compressors are used in industrial settings such as food processing plants, chemical plants, and cold storage facilities to keep products and equipment at specific temperatures.
  5. Transportation refrigeration: Compressors are used to cool the cargo compartments of trucks, trailers, and shipping containers to keep perishable goods fresh during transportation.
  6. Medical refrigeration: Compressors are used to keep vaccines, blood, and other medical products at specific temperatures.
  7. Specialized refrigeration: Compressors are also used in specialized applications such as cryogenics (to produce very low temperatures) and in the production of ice.

In summary, refrigeration compressors are used in a wide range of applications to cool and maintain specific temperatures in order to preserve and protect food, products, equipment, and medical items.

Why compressor is used in refrigerator?

A compressor is used in a refrigerator to compress and circulate refrigerant, which is a substance that absorbs and releases heat as it changes phase. The compressor is the heart of the refrigeration system, and it plays a crucial role in cooling the interior of the refrigerator.

The refrigerant is in a low-pressure, low-temperature liquid form when it enters the compressor. The compressor then compresses the refrigerant, raising its temperature and pressure. This causes the refrigerant to change into a hot, high-pressure gas.

The hot, high-pressure gas is then passed through a set of coils called the condenser coils, where it releases its heat to the surrounding air. As the refrigerant loses heat, it cools down and turns back into a liquid.

The cooled liquid refrigerant is then passed through an expansion valve, which rapidly reduces the pressure and temperature of the refrigerant. This causes it to change into a low-pressure, low-temperature liquid again.

The low-pressure, low-temperature liquid refrigerant is then passed through the evaporator coils located inside the refrigerator, where it absorbs heat from the air inside the refrigerator, causing it to cool. As the refrigerant absorbs heat, it boils and turns back into a gas, completing the refrigeration cycle.
