Refrigeration removes heat from a low-temperature space and rejects it to a high-temperature area. It achieves cooling below ambient temperature through a continuous heat transfer cycle.

Refrigeration is essential for food preservation, preventing spoilage, storing medicines and vaccines, and enabling transport of perishable goods. It is also vital for industrial processes, manufacturing, comfort cooling in homes and offices, and cryogenics in mechanical engineering.
The slide describes the working principle based on the reverse Carnot cycle, specifically the vapor compression refrigeration cycle. It absorbs heat at low pressure in the evaporator and rejects heat at high pressure in the condenser, reversing the heat pump principle.

The slide outlines the refrigeration cycle workflow across four phases: compression (compressor), condensation (condenser), expansion (expansion valve), and evaporation (evaporator). It describes how refrigerant is compressed to high-pressure vapor, condensed to liquid, pressure-reduced for cooling, and evaporated to absorb heat before the cycle repeats.

The slide "Major Components" features a table listing key parts of a refrigeration system and their functions. It covers the compressor (compresses refrigerant vapor), condenser (releases heat, condenses to liquid), expansion valve (reduces pressure), evaporator (absorbs heat), and refrigerant (working fluid like R134a).

The slide, titled "Applications: Domestic & Industrial," lists domestic uses in home refrigerators and air conditioners. It also covers industrial applications like cold storage and food processing.

The slide on Transportation Applications features refrigerated trucks and ships for road and sea transport of perishables like fruits, vegetables, dairy, and meat, maintaining low temperatures to prevent spoilage. It also covers railway reefers, specialized rail cars that preserve goods quality over long distances by avoiding bacterial growth and decay.
