Instead, they rely on other means to remove heat, such as evaporative cooling or thermoelectric cooling. Cyclic methods: These methods involve a continuous cycle of refrigerant compression and expansion. This is the most common type of refrigeration, and it is used in most refrigerators and air conditioners. The two commonly used type on refrigeartion cycles are; Vapor compression refrigeration: This is the most common type of refrigeration, and it is used in most refrigerators and air conditioners. It works by compressing a refrigerant gas, which causes it to heat up. The hot gas is then passed through a condenser, where it cools down and condenses into a liquid. The liquid refrigerant then flows through an expansion valve, which reduces its pressure and causes it to evaporate. The evaporating refrigerant absorbs heat from the surroundings, cooling it down. Absorption refrigeration: This type of refrigeration uses heat to drive the refrigeration cycle. It is often used in solar-powered refrigerators and in refrigerators that are powered by waste heat from other industrial processes. Beside this other refrigeration cycles are, Gas cycle or reverse braton cycle refrigeration, Aircraft or bootstrap refrigeration system, Lithium bromide refrigeration system, electrolux refrigeration cycle. Each refrigeration method has its own advantages and disadvantages. For example, evaporative cooling is very energy-efficient, but it is not as effective in hot, humid climates. Vapor compression refrigeration is very effective, but it requires more energy than other methods. The best refrigeration method for a particular application will depend on a variety of factors, including the temperature that needs to be maintained, the amount of energy available, and the cost of the system. In this lecture the viewer will be able to learn different types of refgrigeartion cycles..
