What is Refrigeration?
Refrigeration is a branch of science and technology that involves the process of removing heat from a space or substance to lower its temperature, resulting in the preservation or cooling of perishable items.
The fundamental principle of refrigeration is based on the cycle of compression, condensation, expansion, and evaporation, typically achieved through the use of a refrigeration system comprising a compressor, condenser, expansion valve, and evaporator.
This technology is widely employed in various applications, such as household refrigerators, air conditioning systems, industrial refrigeration for food storage and processing, and even medical applications like cryopreservation.
The refrigeration cycle begins with the compressor, which pressurizes a low-temperature, low-pressure refrigerant gas. As this gas travels through the system, it undergoes changes in pressure and temperature, leading to the absorption and removal of heat from the desired space.
Ultimately, refrigeration plays a crucial role in modern life by extending the shelf life of food, providing comfort through air conditioning, and supporting essential processes in industries and healthcare.

Heat Removal Process
Refrigeration is a process that involves removing heat from a specific space or substance to lower its temperature. This is achieved through a continuous cycle of compression, condensation, expansion, and evaporation.
-
Key Components
The core components of a refrigeration system include a compressor, condenser, expansion valve, and evaporator. These work in tandem to manipulate the state of a refrigerant, allowing it to absorb and release heat at different stages of the cycle.
-
Applications
Refrigeration finds widespread applications in daily life, from household refrigerators and freezers to air conditioning systems. Industrial refrigeration is also crucial for preserving and processing perishable goods, and it plays a vital role in various industries such as food storage, pharmaceuticals, and chemical processing.
