Which device is located at the end of the liquid line in a refrigeration system?

• A. Compressor
• B. Expansion Device
• C. Evaporator
• D. Condenser

Answer: (B)

The correct choice is the expansion device, which is indeed located at the end of the liquid line in a refrigeration system. This device plays a critical role in the refrigeration cycle by regulating the flow of refrigerant into the evaporator. The expansion device is responsible for reducing the pressure of the refrigerant, allowing it to expand and cool before entering the evaporator where it absorbs heat from the environment, thus facilitating the cooling process. At this point, the refrigerant is still in liquid form and under high pressure after leaving the condenser. The expansion device changes the refrigerant from a high-pressure state to a low-pressure state, which is necessary for refrigeration to occur effectively. This transition is essential for the refrigerant's ability to absorb heat from the indoor environment as it evaporates. While the compressor, evaporator, and condenser are also integral components of the refrigeration cycle, they are located at different points in the system and serve different functions. The compressor is responsible for compressing the refrigerant gas, the evaporator is where heat absorption occurs, and the condenser releases heat to the surroundings. Therefore, the expansion device is specifically the component that follows the liquid line after the condenser, making it the correct answer.
