Agricultural Engineering Practice Exam

Question: 1 / 400

What does the discharge line do in refrigeration systems?

It allows refrigerant to enter the compressor

It discharges hot air from the system

It allows refrigerant to flow from the compressor to the condenser

The discharge line in refrigeration systems plays a crucial role in the transport of refrigerant. Its main function is to carry the refrigerant vapor that has been compressed by the compressor to the condenser. After the refrigerant enters the compressor as a low-pressure vapor, it is compressed into a high-pressure vapor, where it gains temperature and energy. Once this process is complete, the discharge line facilitates the movement of this hot, high-pressure refrigerant towards the condenser, where it will release heat and condense back into a liquid state. This cycle is essential for the refrigeration process, allowing the system to cool the desired space effectively. Understanding the discharge line's role highlights the importance of proper refrigerant flow and system efficiency in refrigeration technology.
