Which sequence outlines the functions of the condenser?

The sequence that accurately outlines the functions of the condenser begins with de-superheating. In this initial phase, the refrigerant vapor, which is superheated after leaving the compressor, first loses some of its heat as it passes through the condenser coils. This process reduces the temperature of the vapor while it remains in its gaseous state.

Following the de-superheating phase, the vapor then moves into the condensing stage, where it is cooled further as it releases latent heat and transitions from a gas to a liquid state. This condensation is critical because it allows the refrigerant to change phase, effectively removing heat from the system and contributing to the overall cooling process.

The final function is sub-cooling, where the refrigerant liquid is cooled below its condensing temperature before it exits the condenser. This extra cooling step improves the efficiency of the refrigerant and ensures that only liquid enters the expansion device, which is essential for optimal system performance.

This sequence—de-superheat, condense, and then sub-cool—illustrates the proper order in which the condenser operates, highlighting its role in managing heat exchange efficiently in the refrigeration cycle.
