What is the correct order for the functions of a condenser?

In a refrigeration or air conditioning cycle, the condenser plays a critical role in the heat exchange process. The correct order of functions for a condenser is to first de-superheat the refrigerant vapor, then condense it into a liquid, and finally subcool that liquid.

Initially, as refrigerant vapor leaves the compressor, it is at a high temperature and pressure, often in a superheated state. The first function of the condenser is to de-superheat this vapor, which means reducing its temperature without turning it into a liquid yet. This is essential to maintain efficient heat transfer in the condenser.

Once the refrigerant is de-superheated, it undergoes the condensation process. Here, the refrigerant changes phase from a vapor to a liquid as it releases heat to the surroundings. This heat exchange occurs through the condenser coils as air or water cools the refrigerant.

Finally, after the refrigerant has condensed, it is further cooled in a process known as subcooling. This step ensures that the refrigerant is entirely in the liquid state before it flows to the expansion valve, leading to increased efficiency and proper functioning of the system.

Understanding this sequence is crucial because each stage prepares the refrigerant for the next step in the cycle, maximizing the
