Vapour absorption refrigeration is a type of refrigeration system that uses a refrigerant-absorbent pair to remove heat from an area or object and provide cooling. Unlike vapor compression refrigeration, which uses a compressor to increase the pressure and temperature of the refrigerant gas, vapor absorption refrigeration uses a chemical process to absorb the refrigerant vapor into an absorbent liquid and then release it as a vapor. The basic working principle of a vapour absorption refrigeration system involves four main components: a generator, an absorber, a condenser, and an evaporator. The refrigeration cycle involves a refrigerant-absorbent pair that circulates through the system, absorbing heat at the evaporator and releasing it at the condenser. Here are the basic steps of how a vapour absorption refrigeration system works: 1. The generator: The generator heats the refrigerant-absorbent pair, causing the refrigerant to evaporate and the absorbent to become concentrated. The vaporized refrigerant then flows to the condenser. 2. The condenser: The high-pressure, high-temperature refrigerant vapor flows to the condenser, where it is cooled and condensed into a liquid by removing the heat from the refrigerant. This is usually done using a cooling medium such as air or water. 3. The absorber: The liquid refrigerant then flows to the absorber, where it is absorbed by the absorbent liquid, creating a low-pressure, low-temperature liquid-vapour mixture. 4. The evaporator: The low-pressure, low-temperature liquid-vapour mixture then flows to the evaporator, where it absorbs heat from the surroundings, providing cooling. The cooled air or object is then circulated through the area or object being refrigerated. As the refrigerant absorbs heat, it evaporates and becomes a low-pressure, low-temperature vapour, which is then drawn back into the generator to start the cycle again. Vapour absorption refrigeration is commonly used in the food processing industry to preserve and store a wide variety of food products. Here are some examples of food products that are processed using vapor absorption refrigeration: 1. Dairy products: Milk, cheese, yogurt, and other dairy products require refrigeration to maintain their freshness and prevent spoilage. Vapour absorption refrigeration is commonly used in dairy processing plants and cold storage facilities to store and transport these products. 2. Fruits and vegetables: Many fruits and vegetables are sensitive to heat and can quickly spoil if not stored at a cool temperature. Vapour absorption refrigeration is commonly used in production processing and cold storage facilities to extend the shelf life of these products. 3. Meat and poultry: Meat and poultry products require refrigeration to maintain their quality and freshness. Vapour absorption refrigeration is commonly used in meat processing plants and cold storage facilities to store and transport these products. 4. Seafood: Seafood products are highly perishable and require careful handling and refrigeration to maintain their quality. Vapour absorption refrigeration is commonly used in seafood processing plants and shipping containers to keep seafood products fresh during transport.
