Which of the following is not a component of a closed cycle compression refrigeration system?

In a closed cycle compression refrigeration system, the primary components include the compressor, condenser, and evaporator. These components work together to facilitate the refrigeration cycle, which operates by absorbing heat from a low-temperature environment and expelling it to a higher temperature environment.

The compressor is responsible for compressing the refrigerant vapor, increasing its pressure and temperature before it moves to the condenser. The condenser then cools and condenses the refrigerant from a vapor to a liquid, allowing it to release heat. The evaporator plays a crucial role by absorbing heat from the environment, causing the refrigerant to evaporate and return to a gas state.

The absorber, however, is not a component of a closed cycle compression refrigeration system. It is typically used in absorption refrigeration systems, which utilize a different mechanism involving a refrigerant and an absorbent. These systems operate differently and are not based on mechanical compression. Therefore, the inclusion of the absorber in a closed cycle compression refrigeration setup is incorrect.
