Where does the gas defrost system line connect?

The gas defrost system line connects from the inlet of the condenser to the inlet of the evaporator. This relationship is crucial for the operation of the refrigeration cycle, particularly during the defrost process.

When ice builds up on the evaporator coils, the gas defrost system diverts hot gas (typically from the compressor) to the evaporator. This hot gas enters the evaporator at the inlet and warms the coil, which helps in melting the accumulated ice. Once the ice has melted, the water can then drain off, allowing efficient operation of the refrigeration system.

This connection is vital because it allows the system to effectively manage the temperature in the evaporator, maintaining performance and efficiency. Understanding this connection is essential for troubleshooting and ensuring that defrost cycles function correctly, making it an important concept for anyone preparing for the Rhode Island Journeyman's Refrigeration License.
